Add: Pour the coffee into a quart-size mason jar. Add protein powder of choice, milk, and sweetener if using.
Shake: Screw the lid tightly. Shake vigorously until the protein powder has dissolved. The milk will foam up on top. Pour into glasses with ice and serve immediately.
Notes
Note: The final macronutrient count will depend on your protein powder. I used collage peptides in the nutrition facts. Storage: Store leftover protein coffee in a sealed container like a mason jar for up to 7 days.Reheat: For warm protein coffee, gently reheat on stovetop in a small saucepan on medium low heat until warmed through.
