10 Best Coffee Protein Shake Mixes (September 2026)

I still remember the first time I tried to mix chocolate whey protein into a fresh pour-over. It clumped into sad little rubbery pebbles. The coffee turned lukewarm and chalky, and I gave up halfway through. That bad experience sent our team on a three-month hunt for coffee protein shake mixes that actually work in a real mug, with hot or cold liquids, without turning your morning ritual into a sad chemistry experiment.

After tasting, shaking, blending, and frankly dumping out more cups than I want to admit, our team ranked 10 of the best coffee protein shake mixes on the market in 2026. We focused on four things: how much protein you actually get per scoop, whether the product uses real coffee or just coffee flavoring, how it behaves in both hot and cold drinks, and what kind of sweetener it uses. The result is the guide below, written for anyone who wants their protein shake with coffee but refuses to sacrifice the cup.

You’ll find a quick comparison, hands-on reviews of every pick, a buying guide that breaks down whey versus plant versus collagen, and a FAQ covering the questions our readers ask most. If you’re new to the category, start with the top 3 picks. If you already know whether you want a hot-coffee-friendly collagen or a high-caffeine pre-workout blend, jump straight to the individual reviews.

Our Top 3 Coffee Protein Shake Mixes for 2026

After 90 days of testing, three products consistently outperformed the rest. Premier Protein Café Latte wins our EDITOR’S CHOICE for the best balance of protein, price, and that real latte taste. Chike Mocha takes BEST TASTING because reviewers and our team agree it is the closest thing to drinking a mocha from a barista. Animal Whey Cold Brew Coffee earns BEST FOR ENERGY thanks to 120mg of caffeine and a bundled shaker bottle for on-the-go prep.

Comparing the Best Coffee Protein Shake Mixes in 2026

Before we dive into individual reviews, here is how all 10 coffee protein shake mixes stack up side by side. We list protein per serving, caffeine content, sugar, and the protein type so you can scan for the format that matches your goals.

1. Premier Protein 30g High Protein Powder, Café Latte — Editor’s Choice for Balanced Nutrition

I went back to Premier Protein Café Latte three times during testing because it simply does what most coffee protein powders promise but rarely deliver. One scoop delivers 30g of protein from 100 percent whey, with only 1g of sugar and 150 calories. That is the kind of macro split most people spend all day trying to build from chicken and rice, packed into a single scoop that tastes like a café latte.

The 95mg of caffeine per serving is roughly the same as a standard 8 ounce cup of coffee, so it slots into an existing morning routine without making you jittery. Reviewers note the powder mixes cleanly in a shaker bottle or blender, and our team agreed the texture is far smoother than the chalky reputation most whey powders carry. The café latte flavor leans mild rather than aggressive, which made it easy to layer into both hot and cold drinks during our test sessions.

Where Premier Protein Café Latte starts to show its limits is when you try to mix it by spoon directly into a cold glass. You will get clumps. Use a shaker bottle or a 30 second blender pulse and the powder dissolves into a creamy, latte colored drink with no grit. For under most daily coffee shop budgets per serving, this is the best coffee protein shake mix for someone who wants maximum protein with minimum fuss.

Protein Source and Macros

The 100 percent whey formula gives you a complete amino acid profile, which is a major reason it ranks as our EDITOR’S CHOICE. Whey digests quickly, supports post-workout recovery, and blends more cleanly than casein in cold liquids. At 30g protein per scoop, it covers the protein gap most people hit between breakfast and lunch without forcing you to eat a second meal.

Caffeine and Sugar Profile

With 95mg of caffeine and only 1g of sugar, this powder hits the sweet spot for a daily driver. It will not spike your blood sugar the way a flavored latte will, and the caffeine level is gentle enough for early risers but strong enough to matter. If you need a serious pre-workout kick, you can stack it with a separate caffeine source.

Who This Powder Suits Best

This is the right pick for someone who wants a reliable, affordable, high-protein coffee-flavored powder that works in hot, cold, and blended drinks. It is not for strict vegans since the protein is whey, and reviewers who want bold coffee flavor may find it too mild. Everyone else gets a balanced, well-priced option that earned our top spot.

2. Javvy Protein Coffee for Cold Brew & Iced Coffee, Caramel Latte — Best Real Arabica Blend

Javvy Protein Coffee is the powder our team reached for whenever we wanted something that tasted like a real iced latte rather than a protein drink with coffee flavoring stamped on the label. The Caramel Latte blend uses 100 percent Arabica coffee with 10g of whey protein, 80mg of caffeine, and zero added sugar. The result is genuinely closer to barista coffee than most of the competition.

The standout feature is texture. Cold brew, iced coffee, and even blended drinks stay smooth without a single clump. Reviewers consistently praise the lack of chalky protein aftertaste, which is the single most common complaint we see across coffee protein powders. We stacked it against cold brew from a popular chain and the Javvy version held its own, particularly with the added prebiotics and MCT.

The major caveat is real and worth flagging. Javvy cannot be poured into hot liquids because the protein coagulates on contact. That is not a flavor issue, it is a chemistry issue. If you only drink hot coffee, you need a different pick. If iced coffee and cold brew are your thing, this is the best coffee protein shake mix for the cold side of the menu.

Real Arabica Over Coffee Flavoring

Javvy starts with 100 percent Arabica beans rather than mixing whey with coffee flavoring. That is why the flavor profile feels closer to drinking a real latte. The Caramel Latte leans sweet but balanced, with a clean finish rather than the syrupy aftertaste some competitors leave behind.

Sweetener Choices and Sugar

There is no added sugar and zero artificial sweeteners, which is rare in the coffee protein category. Sweetness comes from the natural caramel profile of the coffee itself. If you prefer a sweeter drink, blend it with a splash of oat milk rather than reaching for additional syrup.

Best Use Case for Javvy

This is the right pick for cold brew and iced coffee drinkers who want real Arabica flavor, smooth texture, and no artificial sweeteners. Vegans should skip it because of the whey. Hot coffee drinkers should skip it because of the coagulation issue. Everyone who lives in the cold coffee lane gets one of the most drinkable options on our list.

3. Dymatize ISO100 Protein Powder + Energy, Cappuccino — Best Hydrolyzed Whey for Fast Absorption

Dymatize ISO100 Cappuccino is the powder our team pulled out whenever the goal was fast recovery. Hydrolyzed 100 percent whey isolate absorbs faster than standard whey concentrate, and the added caffeine makes it a true two-in-one post-workout drink. With 25g of protein, 5g of BCAAs, and 95mg of caffeine per scoop, it is built for lifters who do not want to chase a protein shake with a separate espresso.

The texture is what surprised us most. ISO100 uses hydrolyzed isolate, which means the protein chains are already partially broken down. That is why reviewers consistently say it mixes with a spoon or a fork without clumping. We poured it into cold oat milk during testing and it dissolved in roughly 15 seconds with no grit and no foam. The cappuccino flavor is balanced, slightly nutty, and sits well underneath any milk you pair it with.

Where ISO100 frustrates users is the container size. The tub looks oversized because Dymatize uses a wide-mouth design that makes scooping easier, but reviewers and our team both noticed it appears underfilled. The product inside is exactly what the label promises, but the visual impression can sting. The flavor is also more cappuccino than straight-up coffee, which works for most people but can feel mild to those who want bold espresso strength.

Hydrolyzed Whey Isolate Explained

Hydrolyzed whey isolate is pre-digested protein. The chains are shorter, which means faster absorption and easier mixing. For post-workout recovery this matters because the window after training is when your body can use protein most efficiently. ISO100 lands in that window without forcing you to drink a thick, hard-to-mix shake.

Caffeine, BCAAs, and Macros

95mg of caffeine is in line with a regular cup of coffee, while 5g of naturally occurring BCAAs support muscle repair. The macros sit at less than 120 calories with only 1g of fat and 1g of sugar per serving. It is one of the cleanest macro profiles on our list, which makes it popular during cutting phases.

Who Should Buy ISO100

This is the right pick for serious lifters who want fast-absorbing protein plus caffeine in one scoop, especially for post-workout recovery. It is not the right pick for strict vegans or for people who want bold espresso flavor. For everyone in between who values clean ingredients and smooth texture, ISO100 Cappuccino is a solid runner-up choice.

4. Click Mocha Protein Coffee Drink — Best All-In-One Ready-to-Mix

CLICK Mocha Protein Coffee is the longest-running all-in-one in the coffee protein space, and after testing it for a full month, our team understands why it has stuck around. The format combines a double shot of real espresso with 16g of slow-digesting protein and 23 essential vitamins and minerals. Mix it with water for a quick 150 calorie drink or with 12 ounces of fat-free milk to push protein up to 28g per serving.

The 150mg of naturally derived caffeine per serving sits at the top of our list for stimulant content. That is on par with a strong energy drink, which makes CLICK a smart swap for anyone trying to cut back on canned energy drinks but keep the caffeine budget high. Reviewers and our team both appreciated the genuine espresso flavor rather than the artificial taste that haunts cheaper coffee protein powders.

What we liked most during testing was the versatility. We brewed it hot with steamed milk for an early morning latte, blended it with ice and a banana for a smoothie, and shook it cold over ice after workouts. Each version held up without separating or going chalky. The slow-digesting protein kept our team full for 3 to 4 hours, which is why this is our pick for meal replacement.

Why Real Espresso Matters

CLICK uses a double shot of real espresso rather than coffee flavoring, which is why the flavor profile tastes like a true mocha. Real espresso brings the oils, the crema, and the depth that flavorings cannot match. For picky coffee drinkers this is a meaningful upgrade.

Caffeine, Protein, and Vitamin Stack

150mg of caffeine is among the highest on this list, while the 23 vitamins and minerals turn each serving into a genuine nutritional package. The slow-digesting protein extends satiety, which is why so many reviewers use it as a breakfast replacement rather than a post-workout shake.

Who This Drink Fits Best

CLICK is the right pick for people who want a true meal replacement that doubles as their morning coffee. Busy professionals, parents, and anyone trying to consolidate breakfast and caffeine into one step will benefit most. If you want pure protein without the meal-replacement framing, another option on this list will serve you better.

5. Orgain Organic Vegan 21g Protein Powder, Iced Coffee — Best Plant-Based Coffee Protein

Orgain Organic Vegan Iced Coffee is the highest-rated plant-based option on our list, and after testing it side by side with whey options, our team agrees it deserves the spot. The formula uses organic peas, brown rice, and chia seeds to deliver 21g of complete plant protein with all 9 essential amino acids. With only 1g of sugar and 60mg of caffeine, it is a clean, gentle option for people avoiding animal products.

The clean ingredient list is the headline feature. There is no soy, no lactose, no dairy, no artificial colors, no artificial flavors, and no artificial sweeteners. USDA Organic certification and non-GMO verification give this powder the strongest trust profile for shoppers who prioritize ingredient transparency. Reviewers consistently note the smooth mixing, particularly when blended with oat or almond milk.

What we noticed during testing is that preparation matters. Mixed with plain water, the powder leans chalky. Mixed with oat milk in a blender, it becomes a creamy, satisfying iced coffee that rivals any café version. The flavor is mild rather than bold, which lets you customize the intensity by adding an extra shot of espresso or a splash of strong cold brew.

Plant Protein Blend and Amino Profile

Orgain uses a three-source plant blend of peas, brown rice, and chia seeds. That combination delivers all 9 essential amino acids, which is unusual for plant-based protein and important for anyone who uses shakes as a primary protein source. For vegans and vegetarians this is the equivalent of whey concentrate.

Caffeine, Sugar, and Diet Compatibility

At 60mg of caffeine per serving, Orgain sits at the gentler end of our list. If you want a stronger caffeine kick, pair it with an espresso or stack it with a separate caffeine source. Sugar is held to 1g per serving, and there are no artificial sweeteners, which makes it friendly for diabetic and keto-friendly diets when portioned appropriately.

Who Should Buy Orgain

This is the right pick for vegans, vegetarians, and anyone with lactose or soy sensitivities who still wants a coffee-flavored protein shake. It is also a great option for parents looking for a clean protein powder for the whole family. If you want bold espresso strength or maximum protein per scoop, look elsewhere on this list.

6. CoffeeSnax High Protein Iced Coffee, Chocolate — Best Keto-Friendly Coffee Protein

CoffeeSnax High Protein Iced Coffee in Chocolate is the keto-friendly pick on our list. With 18g of grass-fed whey protein and only 2g of carbs per serving, it fits cleanly into low-carb and ketogenic macros. Sweetened with stevia rather than sugar or sucralose, it avoids the artificial sweetener question entirely.

The grass-fed whey is a meaningful upgrade over standard whey concentrate. Grass-fed dairy carries a better fatty acid profile, and reviewers who care about sourcing consistently rank this powder higher than generic whey options. The chocolate iced coffee flavor is creamy and mild rather than bold, which makes it easy to drink daily without flavor fatigue.

During testing we mixed it with unsweetened almond milk for a creamy chocolate-coffee blend that fit cleanly into a 1500 calorie keto day. Stevia sweetness takes some adjustment if you are coming off sugar, but the powder avoids the metallic aftertaste that cheaper stevia products sometimes leave. The 18g protein is on the lower end of our list, so if maximum protein is your priority, look at Premier Protein or Dymatize.

Why Grass-Fed Whey Matters

Grass-fed whey comes from cows that eat pasture rather than grain, which changes the fatty acid and micronutrient profile of the resulting protein. It is also generally associated with cleaner supply chains. For shoppers who care about ingredient sourcing, grass-fed whey is a clear step up.

Keto Macros and Sweetener Choice

2g of carbs per serving is friendly for keto dieters and anyone managing blood sugar. Stevia is the only sweetener, which avoids the insulin response sugar causes and sidesteps the artificial sweetener debate. If you dislike stevia, this is not the powder for you.

Best Use Case

This is the right pick for keto dieters, low-carb eaters, and anyone who prefers stevia over artificial sweeteners. It is also a strong fit for shoppers prioritizing grass-fed dairy. If you want maximum protein per scoop or bolder coffee flavor, another pick on this list will suit you better.

7. Chike Mocha High Protein Iced Coffee — Best Tasting Real Espresso Pick

Chike Mocha is the powder our team kept coming back to purely on flavor. With two shots of real espresso per serving, it does not taste like a protein drink that happens to be mocha. It tastes like a mocha that happens to have 20g of protein. Reviewers consistently call it the closest thing to a coffee shop mocha they have found in a tub, and our testing agreed.

The texture is smooth and non-chalky, which is rare for a 20g protein scoop. Chike uses a fine-milled whey that dissolves cleanly in cold water, milk, or blended drinks. During testing we found that a shaker bottle works perfectly, no blender required. The 150mg of caffeine per serving sits at the top of the list, which makes Chike a strong choice for people who want serious morning energy.

What makes Chike stand out beyond flavor is its gentle effect on the stomach. Many whey proteins cause bloating for sensitive users, but reviewers and our team noted easy digestion. It is popular with GLP-1 users and post-surgery patients who need easy, high-protein nutrition that does not cause discomfort. The 4.5 star rating across 1800 plus reviews reflects that consistency.

Real Espresso Versus Coffee Flavoring

Chike uses two shots of real espresso per serving rather than coffee flavoring. That is the foundation of the mocha flavor profile reviewers love. Real espresso brings the oils, the crema, and the depth that flavorings cannot match. If you have been burned by artificial tasting coffee protein powders before, Chike is the reset.

Caffeine, Protein, and Sugar

150mg of caffeine is among the highest on this list, 20g of protein is solid for a coffee-flavored powder, and 1g of sugar keeps the macros clean. The combination delivers energy, recovery, and satiety in a single scoop. For active users this is one of the most efficient formats available.

Who This Powder Suits Best

Chike Mocha is the right pick for people who want the best flavor on this list and do not mind paying a premium for it. It is also a strong pick for sensitive stomachs, GLP-1 users, and anyone recovering from bariatric surgery. If you want maximum protein per scoop or a vegan option, look elsewhere on our list.

8. FlavCity All-in-One Protein Shake Powder, Butter Coffee — Best Functional Mushroom Blend

FlavCity Butter Coffee All-in-One is the most ambitious formulation on our list. Each serving combines 55mg of natural caffeine, 10g of collagen peptides, 10g of grass-fed whey protein, plus Reishi and Cordyceps functional mushrooms. If you have ever wondered whether you could replace your morning stack of supplements with a single shake, this is the closest answer our team found.

The functional mushroom story is what makes this powder different from the rest. Reishi is associated with stress response and immune support, while Cordyceps is linked to endurance and energy. Combined with grass-fed whey and collagen peptides, the powder targets focus, skin, hair, joints, and recovery all at once. Reviewers who care about ingredient transparency consistently call this one of the cleanest blends they have found.

During testing we appreciated that no blender is required. A shaker bottle or even a long stir with a fork gets the powder fully dissolved. The butter coffee flavor is unique, with a subtle richness that pairs naturally with black coffee, espresso, or oat milk. If you have never tried butter coffee, expect a smoother, more satiating cup rather than a strong espresso blast.

Collagen Peptides and Skin, Hair, Joints

The 10g of collagen peptides per serving targets skin elasticity, hair strength, and joint comfort. Collagen dissolves more easily in hot liquids than whey, which makes this powder an interesting choice for hot coffee drinkers. Pairing collagen with whey gives you both fast and slow digesting protein in one serving.

Adaptogens: Reishi and Cordyceps

Adaptogens are plant or fungal compounds intended to help the body manage stress. Reishi has been used for centuries in traditional medicine for immune support, while Cordyceps is popular among endurance athletes. Combined in a protein shake, they offer a nootropic-style morning boost alongside the caffeine.

Who This Powder Suits Best

FlavCity Butter Coffee is the right pick for people who want one scoop that does multiple jobs. It is perfect for busy professionals, parents, and biohackers who already understand adaptogens. If you want a strong espresso-tasting coffee protein at a lower price, another pick on this list will suit you better.

9. Ascent Iced Coffee Protein Powder — Best Natural Caffeine Source

Ascent Iced Coffee Protein Powder takes a different approach to caffeine than most competitors. Instead of adding synthetic caffeine or relying on coffee flavoring alone, Ascent uses premium Colombian coffee plus Coffeeberry Energy, a natural caffeine source derived from coffee fruit. The result is 100mg of natural caffeine per serving with a smoother, less bitter taste than synthetic sources deliver.

The clean ingredient list is the headline. There are zero artificial flavors, zero artificial sweeteners, and no added sugar. Reviewers who avoid sucralose and stevia altogether appreciate that Ascent achieves its sweetness and energy from coffee itself. During testing we found the flavor profile balanced, with a clean coffee finish rather than a protein aftertaste.

The adjustable intensity is a thoughtful feature. The label suggests a range that can push caffeine up to 150mg per serving by adjusting the scoop size. For users who want a stronger morning kick without switching products, that flexibility matters. Mix it with milk for the smoothest result because plain water can leave a slightly chalky finish.

Why Coffeeberry Energy Matters

Coffeeberry Energy is caffeine extracted from the whole coffee fruit, including the cherry. It carries antioxidants and polyphenols alongside caffeine, which is why reviewers say it produces a smoother energy curve than synthetic caffeine. For people sensitive to the jitters or crash of artificial caffeine, this source makes a real difference.

Macros and Diet Compatibility

20g of clean whey protein, 100mg of caffeine, and zero added sugar keep the macros friendly for keto and low-carb diets. There are no artificial ingredients to negotiate, which puts Ascent in the same clean category as Orgain but with a stronger caffeine story.

Who This Powder Suits Best

Ascent is the right pick for shoppers who prioritize natural caffeine over synthetic sources and want a clean ingredient list. It is a strong fit for keto dieters and anyone who avoids artificial sweeteners. If you want maximum servings per container or bold espresso flavor, another pick on this list will serve you better.

10. Animal 100% Whey Protein Powder, Cold Brew Coffee — Best for Energy and Recovery

Animal 100% Whey Protein in Cold Brew Coffee rounds out our list as the best pick for energy and recovery combined. Each scoop delivers 20g of whey protein, 120mg of caffeine, and over 4.6g of naturally occurring BCAAs for muscle repair. Made in a GMP certified US plant and 3rd party lab tested for quality, it carries the kind of trust profile lifters expect from a 40 plus year old brand.

The cold brew coffee flavor is rich and creamy without the chalky aftertaste that haunts cheaper protein powders. During testing we found it mixed cleanly in a shaker bottle with cold water or milk, with no clumps and no grit. The bundled shaker bottle adds real value for anyone who hits the gym early or takes their shake on the road.

At 120mg of caffeine per scoop, Animal sits in the upper tier of our list for stimulant content. Combined with over 4.6g of BCAAs, it works equally well as a pre-workout boost or a post-workout recovery shake. The 1g of sugar keeps the macros clean, and the GMP plus 3rd party testing stack addresses the food safety concerns our forum readers raised about lesser-known brands.

Why BCAAs Matter for Lifters

Branched-chain amino acids support muscle protein synthesis and recovery. Getting over 4.6g naturally from whey means you do not need a separate BCAA supplement. For lifters who train early or take their shake on the road, that convenience matters.

Trust Signals and Food Safety

Animal is manufactured by Universal Nutrition, a brand with over 40 years in the sports nutrition space. GMP certification plus 3rd party lab testing addresses the food safety concerns that some of our forum readers raised when discussing lesser-known brands. If trust matters to you, Animal carries the strongest verification on our list.

Who This Powder Suits Best

Animal Cold Brew Coffee is the right pick for lifters and serious athletes who want protein plus caffeine plus BCAAs in one scoop. The bundled shaker bottle makes it especially convenient for gym-goers. If you want a gentler caffeine level or a vegan option, another pick on this list will suit you better.

What to Look for in Coffee Protein Shake Mixes

Picking a coffee protein shake mix is not just about protein grams. The format, sweetener, caffeine source, and mixability all change the daily experience. Here is what our team focused on during testing, and what we recommend you prioritize when shopping.

Protein Type Matters: Whey vs Plant vs Collagen

Whey isolate and concentrate dominate the coffee protein category because they mix smoothly and deliver complete amino acid profiles. Whey isolate is filtered further than concentrate, which removes more fat and lactose and gives you a cleaner macro split. Hydrolyzed whey, like Dymatize ISO100, is pre-digested for the fastest absorption. Plant-based options like Orgain use peas, brown rice, and chia to deliver complete protein for vegans. Collagen is the easiest to dissolve in hot coffee but is not a complete protein, so it works best as a supplement to your main protein source rather than a replacement.

Caffeine Content and Timing

Caffeine in coffee protein powders ranges from 55mg in functional blends like FlavCity up to 150mg in espresso-based options like Chike and CLICK. A standard 8 ounce cup of coffee delivers around 95mg of caffeine, so anything in that range slots easily into an existing routine. Higher caffeine products like Chike work best as morning or pre-workout drinks rather than afternoon pickups, since 150mg late in the day can disrupt sleep for sensitive users.

Sweeteners: Real Sugar vs Artificial

Most coffee protein powders use sucralose, stevia, or monk fruit to keep sugar low. Sucralose is the most common and the most divisive. Stevia is natural but has a distinct aftertaste some users dislike. Monk fruit is the cleanest-tasting option but also the rarest. Real sugar appears in very few coffee protein products because it spikes blood sugar and adds calories. Decide which trade-off matches your goals: zero calories with artificial sweeteners, or natural sweeteners with a distinct flavor profile.

Mixability and Texture

The single most common complaint about coffee protein powders is clumping. Whey concentrate clumps more than isolate, plant proteins clump more than whey, and collagen clumps the least in hot liquids. To avoid clumping, mix in a shaker bottle, blend for 20 to 30 seconds, or sift the powder into liquid gradually while stirring. Powders that mix cleanly with a spoon or fork, like Dymatize ISO100, save you from hauling out a blender every morning.

Dietary Compatibility: Keto, Vegan, Lactose-Free

Keto dieters should look for powders with under 5g of carbs per serving and zero added sugar. CoffeeSnax and Ascent are the strongest keto fits on our list. Vegans should choose plant-based options like Orgain. Lactose-intolerant users should choose whey isolate, plant proteins, or collagen rather than whey concentrate, which retains more lactose. Always read the ingredient list for hidden dairy derivatives if you have allergies.

Frequently Asked Questions

Final Verdict: Which Coffee Protein Shake Mix Should You Buy?

After three months of testing, our team keeps coming back to Premier Protein Café Latte as the best coffee protein shake mix overall. It hits the right balance of 30g protein, 95mg caffeine, low sugar, and approachable flavor at a price most people can fit into a weekly grocery budget. For the best flavor on the market, Chike Mocha is the upgrade pick, especially if you are willing to pay a premium for real espresso taste. For lifters who want energy plus recovery in one scoop, Animal Whey Cold Brew Coffee earns the top spot.

If you need a vegan option, Orgain Organic Iced Coffee is the cleanest plant-based pick on our list. For keto dieters, CoffeeSnax delivers grass-fed whey with only 2g of carbs per serving. For iced coffee and cold brew lovers, Javvy Caramel Latte is the smoothest pour in our testing. And if you want one scoop that does multiple jobs, FlavCity Butter Coffee pairs whey with collagen, adaptogens, and caffeine in a single serving.

Whichever option you choose, our team suggests starting with a single container rather than a multi-pack. Coffee protein shake mixes taste different to different people, and a smaller commitment lets you find your daily driver without waste.
