Protein Mug Cake


  • Cooking spray
  • ½ small ripe banana
  • 2 tablespoons (about 15 grams) chocolate or vanilla protein powder of your choice
  • 1 tablespoon peanut butter, plus more for topping
  • 1 tablespoon milk or milk-alternative of your choice
  • 1 tablespoon dark chocolate chips
  • ¼ teaspoon baking powder


Spray a large mug with cooking spray. Add banana to mug and mash until mostly broken down.

Add in protein powder, peanut butter, milk, chocolate chips and baking powder. Stir until everything is fully combined into a batter-like consistency. Microwave for 60 to 75 seconds. Then, let cool for 30 seconds. Batter should be mostly dry to the touch and have a cakey texture.

Enjoy with more peanut butter and chocolate chips over top, if desired.

Cooking note:

  • You want to use a large mug because the cake will puff up in the microwave when it cooks. Using a large mug prevents it from spilling over the sides.
