Equipment

  • 4.7-inch baking dish
  • Oven

Ingredients
  

For the Cake:

  • 1/4 cup oat flour
  • 1/4 cup protein powder (casein or vegan recommended)
  • 2 tbsp cocoa powder

  • Preheat oven to 350° F
  • In a mixing bowl, combine oat flour, protein powder, cocoa powder, sweetener, and baking powder.

  • Pour batter into the dish and smooth the surface evenly.
  • Bake for 20 to 25 minutes, or until the center is just set.
  • Let cool slightly before serving. Add low-calorie Nutella and chocolate chips if desired.
