Protein Coffee
That Actually Tastes Great
Combine your morning coffee and post-workout protein shake into one smooth, energizing drink.
“Proffee” (protein + coffee) became a viral fitness trend — and for good reason. It solves two morning problems at once: getting your caffeine hit and hitting your protein targets, all in one convenient, genuinely delicious drink. If you skip breakfast but need to fuel a workout, this is your answer.
Our protein coffee recipe delivers around 25g of protein alongside the caffeine of two espresso shots. It’s smooth (no grittiness if you follow the method), mildly sweet, and takes 5 minutes from start to sip.
This pairs perfectly with our broader coffee recipes collection and slots beautifully into any healthy recipe routine.
*Approximate values based on 1 scoop whey isolate + 200ml semi-skimmed milk + 2 espresso shots.
Protein Coffee Recipe (Proffee)
High-protein, energizing, ready in 5 minutes
🛒 Ingredients
- 2 espresso shots (60ml) or 120ml cold brew
- 1 scoop protein powder (vanilla or mocha)
- 200ml cold milk or oat milk
- 1 cup ice cubes
- 1 tsp sweetener (optional)
- Cinnamon or cocoa to garnish
👨🍳 Instructions
- Let espresso cool to lukewarm. Hot liquid causes protein powder to clump badly.
- In a shaker or blender, combine protein powder + cold milk. Shake until completely smooth.
- Fill a large glass with ice all the way to the top.
- Pour cooled coffee over ice, then slowly pour protein milk on top. Stir, taste, and garnish.
Choosing the Best Protein Powder for Coffee
Whey Isolate (Best Overall)
Whey protein isolate dissolves most cleanly and has a neutral flavour that complements coffee without fighting it. Vanilla whey + espresso = a genuine latte-style experience. It’s our top pick for protein coffee.
Casein (Best for Staying Power)
Casein protein digests more slowly than whey, meaning it keeps you satiated for longer. Great if protein coffee is replacing breakfast before a mid-morning workout.
Pea Protein (Best Plant-Based Option)
Pea protein is the plant-based winner — relatively neutral flavour and mixes more cleanly than brown rice or hemp protein. Blend thoroughly with milk before adding coffee.
Avoid These
Soy protein tends to foam excessively. Hemp and brown rice proteins can give a gritty texture. Collagen peptides work but add minimal protein per scoop (8–10g). Stick with whey, casein, or pea for best results.
Best Flavour Pairings
Vanilla + Espresso: Classic, clean, like a vanilla latte. Mocha + Cold Brew: Deep chocolate and coffee harmony. Caramel + Espresso: Sweet, warming, dessert-like. Unflavoured + anything: Total control over taste — add your own syrups and spices.
Variations to Try
Frozen Protein Coffee (Frappé Style)
Blend everything together in a blender with a full cup of ice. The result is a thick, icy protein frappé — almost like a coffee milkshake. Outstanding on hot mornings.
Hot Protein Coffee
Yes, you can make it hot. Use cold brew concentrate as the base (room temperature), heat your milk separately until warm (not boiling), then mix in protein powder and stir gently. Never use boiling liquid — proteins denature and you get a grainy mess.
Mocha Protein Coffee
Add 1 tsp unsweetened cocoa powder to the protein-milk mixture before shaking. The result is a rich mocha that genuinely tastes like a café drink — but with 25g of protein.
Frequently Asked Questions
What protein powder works best in coffee?
Whey isolate is the best overall choice — it dissolves cleanly and has a neutral flavour. For dairy-free, pea protein is the winner. Always shake with cold milk before adding coffee. Vanilla and mocha flavours work best.
Can you put protein powder in hot coffee?
You can, but avoid very hot liquid. High heat denatures the protein and causes clumping. Use room-temperature or lukewarm coffee, or better yet, cold brew concentrate. Always pre-mix protein with cold milk first.
How much protein is in protein coffee?
Using 1 scoop of whey (25g protein) and 200ml semi-skimmed milk (7g protein), you get approximately 32g of total protein per serving — a substantial portion of most daily protein goals in a single drink.
Is protein coffee good before a workout?
Excellent. The caffeine boosts alertness and physical performance, and protein primes muscle protein synthesis before resistance training. Drink 30–60 minutes before your session.
Can I use cold brew instead of espresso?
Absolutely — cold brew concentrate works even better because it’s already cold and mixes more smoothly with the protein milk. See our full cold brew coffee guide to make your own at home.
