Ingredients

Scale
  • 1 scoop (30g) protein powder (vanilla, chocolate, or your favorite flavor)
  • 2 tablespoons oat flour (or almond flour for low-carb)
  • ½ teaspoon baking powder
  • 1 teaspoon cocoa powder (optional, for chocolate flavor)
  • 1 egg (or 3 tablespoons unsweetened applesauce for egg-free)
  • 3 tablespoons milk (dairy or non-dairy)
  • ½ teaspoon vanilla extract
  • 1 teaspoon honey or maple syrup (optional, for sweetness)
  • 1 teaspoon peanut butter or chocolate chips (optional, for extra flavor)

Instructions

1. Mix the Batter
  1. In a microwave-safe mug, mix protein powder, oat flour, baking powder, and cocoa powder (if using).
  2. Add the egg, milk, vanilla extract, and sweetener. Stir well until a smooth batter forms.
  3. Mix in peanut butter or chocolate chips if desired.
2. Microwave the Mug Cake
  1. Microwave on high for 60–90 seconds. Check at 60 seconds—if the center is still wet, microwave for another 15–30 seconds until set.
  2. Let cool for 1 minute before eating.
3. Serve & Enjoy
  1. Top with Greek yogurt, nut butter, or berries for extra flavor!

Storage & Reheating
  • Best eaten fresh, but can be stored in the fridge for up to 24 hours.
  • Reheat in the microwave for 15–20 seconds.

Notes

  • Use casein or whey protein for different textures. Casein makes it denser; whey makes it fluffier.

  • Want it fudgy? Add 1 teaspoon melted chocolate or ½ mashed banana to the batter.
