I've been on a mission to increase my protein intake, and this protein coffee (also called proffee) has become one of my favorite ways to do it. I'm a mom of a three-year-old and a marathon runner — coffee is non-negotiable, and so is protein. This gives me both at once, in about 3 minutes, before I've even fully woken up. It's kind of changed my mornings.
After listening to Mel Robbins's podcast with Dr. Stacy Sims, I started drinking my protein coffee before or during my lifting sessions, and my workouts have noticeably improved. The combination of caffeine and protein means I'm energized going in, and my recovery is faster coming out.
Beyond the performance angle, it's just genuinely delicious — creamy, lightly sweet, and way more satisfying than regular coffee on an empty stomach.

How to Make Protein Coffee — Quick Guide
The fastest way to make protein coffee (proffee):
Iced:
- Brew 1–2 shots of espresso or strong coffee
- Add 1 cup milk + 1 scoop protein powder to a shaker bottle
- Shake well until smooth and no clumps remain
- Pour over ice.
- Top with espresso shots
- Garnish as desired and enjoy
Hot:
- Brew a cup of strongly brewed coffee
- Add coffee, 1 scoop protein powder, and a splash of milk (optional) to a blender
- Blitz until frothy, smooth, and creamy
- Pour into a mug and enjoy
Either way, the whole thing takes about 3 minutes.
Best Protein Powder for Coffee
"Best protein powder for coffee" is one of the most searched questions in this space — and the answer matters, because not all proteins behave the same way in coffee.
Whey isolate — The gold standard for protein coffee. Mixes the smoothest, least clumping, and has a clean flavor that doesn't compete with the coffee. My personal go-to. Isopure Vanilla is my current favorite — no added sugar, great natural flavor.
Casein — Thicker texture, which some people love for a creamier drink. Works better in iced versions; can get gelatinous if you're not careful with hot coffee.
Collagen peptides — Neutral flavor and dissolves well in both hot and cold coffee without clumping. Collagen (affiliate link) doesn't add as much protein per scoop as whey or casein (about 10–11g vs. 20–25g), but it's a great option for a lighter boost and neutral flavor.
Plant-based proteins — Pea, hemp, and brown rice proteins can be gritty or chalky in coffee. To minimize this: shake very well or use a blender, and choose a brand with a good texture. Flavored plant proteins tend to work better than unflavored in coffee.
What to avoid — Proteins with a lot of artificial sweeteners can taste medicinal in coffee. Proteins that clump badly (some vegan blends) are frustrating to work with. Test your powder in just milk first before committing to it in coffee.
Coffee Guide
The coffee is the other half of this equation. Here's what works:
- Espresso — Most concentrated, best flavor. 1–2 shots is the sweet spot. I use a Vertuo Nespresso at home.
- Moka Pot — My backup when I'm out of Nespresso pods. Makes a rich, strong espresso-style coffee that works beautifully in proffee.
- Cold brew concentrate — Smooth, less acidic, and naturally cold — no waiting for hot coffee to cool. 2 oz of concentrate works well.
- Strong French press — Budget-friendly and flavorful. Brew it extra strong to stand up to the milk and protein powder.
- Strong-brewed drip coffee — Perfect for the hot protein coffee version. Just brew it extra strong so it holds up against the milk and protein powder.
- Instant espresso powder — Quick and underrated. Mix with a small amount of hot water, and you're good to go.
What NOT to use: weak drip coffee. It gets completely lost behind the protein and milk, leaving it watery and lifeless. Whatever you use, brew it strong.
Milk & Liquid Options
The milk determines the creaminess and protein count of your proffee:
- Coconut milk — Tropical, slightly sweet, adds a creamy richness
- Dairy milk (2% or whole) — Classic, creamy, bumps protein up to about 33g per serving
- Filtered milk (such as Fairlife) — Ultra-filtered for higher protein — about 38g per serving and naturally lactose-free
- Soy milk — Highest protein of the non-dairy options, roughly equivalent to regular dairy
- Oat milk — Creamy and naturally sweet, but lower in protein. Great flavor pairing with coffee
- Almond milk — Light and low-calorie, but lower protein (about 25g total per serving)
Important Ingredients & Substitutions
Protein powder — See the guide above. Vanilla and chocolate are the most versatile flavors. Use one you enjoy drinking on its own — if you don't like it plain, you won't like it in coffee either.
Coffee — Espresso, cold brew concentrate, or strong-brewed coffee (drip or French press). You can also use espresso powder mixed with hot water. The stronger the better, so it holds up against the milk and protein.
Milk — Any milk works. To maximize protein, use dairy, soy, or filtered milk (such as Fairlife).
Optional garnish — A teaspoon or two of coarse turbinado sugar (like Sugar in the Raw) is my personal favorite — it adds a slight crunch and sweetness without being overwhelming. You can also use cinnamon, cocoa powder, pumpkin pie spice, or a sugar substitute. These are all totally optional, but they add a nice finishing touch.
Iced vs. Hot Protein Coffee
Iced protein coffee (proffee) — The classic version and by far the easiest. Mix protein powder with cold milk, pour over ice, and top with espresso. The ice prevents any clumping issues, and the cold temperatures keep everything smooth.
Hot protein coffee — Requires a different approach than iced. Add strongly brewed coffee, a scoop of protein powder, and a splash of milk (if preferred) to a blender and blitz until frothy, smooth, and creamy. The blender fully incorporates the protein powder, creating a latte-like texture. Don't add protein powder to hot coffee and stir — it will be very clumpy.
The Clumping Problem — and How to Fix It
Clumping is the #1 complaint about protein coffee, and it's fixable. Here's why it happens and how to prevent it:
Why it happens: Hot liquid denatures (partially cooks) some proteins, causing them to clump. Some protein powders — especially plant-based — also clump in cold liquid if not mixed properly.
How to prevent clumping:
- Always shake or blend protein powder with milk first, before adding coffee
- Let hot espresso or coffee cool for 2–3 minutes before adding it
- Use a shaker bottle with a metal mixing ball — it breaks up clumps much more effectively than stirring
- For hot coffee: use the blender method or a premade shake (affiliate link)
- Whey isolate clumps the least — if clumping is a persistent problem, try switching your protein powder
If it already clumped: Pour the whole thing into a blender and blend for 20–30 seconds. Saves the drink every time.
Recipe Variations
One of the things I like best about protein coffee is the endless ways to enjoy it, such as:
- Hot Protein Coffee — Add strongly brewed coffee, a scoop of protein powder, and a splash of milk (if preferred) to a blender. Blitz until it is smooth and creamy. Pour into a mug and enjoy.
- Extra Protein — Use dairy or soy milk for 33g protein, or Fairlife filtered milk for about 38g protein per serving.
- Premade Shake Shortcut — Swap the powder + milk for a premade protein shake (Premiere Protein, Fairlife, etc.) — pour directly over ice and top with espresso.
- Mocha Proffee — Use chocolate protein powder instead of vanilla.
- Caramel Latte — Use caramel-flavored protein powder (affiliate links) for a better-for-you caramel macchiato situation.
- Peanut Butter — Add 1 tablespoon of peanut butter powder to the shaker with vanilla or chocolate protein — adds 3–4 extra grams of protein and an indulgent, nutty flavor.
- Collagen Coffee — Swap whey for collagen peptides for a neutral-flavored, naturally sugar-free option.

Chelsea's Recipe Pro-Tips
- Shake the protein and milk first — For iced coffee, always mix protein powder with milk in the shaker bottle first before adding espresso. The only exception is the hot blender method — there you can add the protein powder directly since the blender does the work of incorporating everything smoothly.
- Let the espresso cool slightly — Even for iced coffee, very freshly pulled espresso can cause some clumping when it hits the protein milk. Give it 2–3 minutes before pouring.
- The shaker bottle matters — A metal mixing ball breaks up clumps far more effectively than just shaking with a lid. A shaker bottle (affiliate link) is worth the investment if you're making this regularly.
- Garnish makes it feel special — The turbinado sugar crunch at the top is one of life's small pleasures and it genuinely elevates the whole drink. Don't skip it if you're not strictly low-sugar.
- Use a protein you actually like — This sounds obvious but it matters more here than in a smoothie because its flavor is front and center, alongside the coffee. If you don't like your protein powder on its own, you won't like it in proffee.
Make-Ahead & Large Batch Directions
One of the many things I love about this proffee recipe is how easy it is to prep in advance. Sad to say, some mornings are just too busy for a 3-minute recipe (IYKYK😫).
Make-ahead: Combine the espresso and 1 cup of milk in a shaker bottle, shake well, cover, and refrigerate overnight. In the morning, add the protein powder, shake again, and serve over ice. The whole morning routine just got 2 minutes faster.
Large batch: Multiply the milk and protein powder by however many servings you need, blend until smooth in a blender, divide among glasses of ice, and top with espresso shots per glass. I love making these after Saturday morning long runs — serve with Cottage Cheese Muffins, Banana Zucchini Muffins, or Peach Coffee Cake for a fantastic post-run spread.
Serving Suggestions
Let's be real — protein coffee is not a complete meal on its own (what can I say? I'm an eater!). On most mornings, I'll pair it with a banana, an apple, or a piece of peanut butter toast to power me through until lunch.
On heavier training days, Chocolate Protein Overnight Oats alongside is my go-to. For a post-run brunch or group workout coffee hour, Protein Oatmeal Breakfast Cookies or Brownie Baked Oatmeal are both crowd-pleasers that can be made ahead and pair perfectly with the coffee.
Protein Coffee (Profee) FAQs
Protein coffee — also called proffee (a portmanteau of "protein" and "coffee" that went viral on TikTok) — is espresso or strong coffee combined with protein powder and milk. It's a convenient way to hit your daily protein goals while enjoying your morning coffee. A standard serving delivers 25–38 grams of protein depending on the milk and protein powder used.
Always mix your protein powder with cold or room-temperature milk in a shaker bottle first — never add it directly to hot coffee unless blending. For hot protein coffee, use the blender method or a premade protein shake. Whey isolate clumps the least of all protein types.
Whey isolate mixes the smoothest and has the cleanest flavor and smoothest texture in coffee. Collagen peptides (affiliate link) are a close second — neutral flavor and dissolve easily in both hot and cold. Plant-based proteins can work, but tend to be grittier — blend them thoroughly and choose a flavored variety.
Yes — but skip the shaker bottle. Add strongly brewed coffee, a scoop of protein powder, and a splash of milk (optional) to a blender and blitz until frothy, smooth, and creamy. The blender fully incorporates the protein, creating a latte-like texture. Don't stir protein powder directly into hot coffee — it will clump.
It depends on your protein powder and milk. With whey protein powder and almond milk: about 25g. With whey + 2% dairy milk: about 33g. With whey + Fairlife filtered milk: about 38g.
Yes — and there's solid research to back it up. Studies show that consuming protein around workouts significantly increases muscle protein synthesis and supports both performance and recovery. Protein in the morning also helps — research indicates that a high-protein breakfast can support healthy glucose levels throughout the day and keep you fuller longer compared to a higher-carbohydrate meal. The overall nutrition profile of your protein coffee will depend on your protein powder and milk choice, but as a morning ritual, it's a genuinely solid way to start the day.
Yes — collagen peptides dissolve well in both hot and cold coffee, have a neutral flavor, and won't add artificial sweeteners or strong flavors. They deliver about 10–11g of protein per scoop (less than whey), so it's a lighter protein boost. Great if you want the benefits of collagen without altering the taste of your coffee much.
