Protein Coffee:
The Ultimate Recipe Guide.

Everything you need to make protein coffee at home — hot, iced, no clumps, 20g+ of protein per cup.

What is protein coffee?

Protein coffee (also called "proffee") is regular coffee fortified with protein — either from a sachet that already blends arabica with whey, or by stirring protein powder into brewed coffee. The result is a single cup that pulls double duty: caffeine to start your day, and 15–25g of protein to actually keep you full.

How to make protein coffee — hot

  1. Brew 150–200ml of coffee at 80–90°C. Boiling water scrambles whey, so let it cool 30 seconds off the kettle.
  2. Add 1 scoop of whey protein (or 1 Blackn Brownn protein coffee sachet) to your mug.
  3. Add 50ml of warm water first and stir into a smooth paste — this is the no-clumps trick.
  4. Pour the brewed coffee in slowly while stirring. Top with milk if you like it creamy.

How to make iced protein coffee

  1. Dissolve 1 sachet (or 1 scoop of protein powder) in 50ml warm water. Stir until smooth.
  2. Add 150ml cold milk or cold water and a tall glass of ice.
  3. Stir for 10 seconds, or shake in a closed bottle for a frothy finish.

Can you put protein powder in coffee?

Yes — with two rules. First, don't pour boiling coffee directly onto dry powder; whey denatures above ~90°C and goes grainy. Second, always make a paste with a splash of warm water before adding the rest of the liquid. That single step solves the clumping problem nearly every home recipe runs into.

Best ratio for high-protein coffee

For a 250ml cup, aim for 1 scoop of whey (20–25g protein) + 150ml coffee + 100ml milk. If you're using Blackn Brownn protein coffee sachets, one sachet already carries 4–5g of protein; pair with 200ml of milk for a 12–15g cup without any powder.
