  • Total Time: 5 minutes
  • Yield: 1 serving

Ingredients

Wet Ingredients

  • 1 large egg
  • 3 tablespoons milk (preferably coconut milk)
  • 1 tablespoon maple syrup

Dry Ingredients

  • 2 tablespoons chocolate protein powder
  • 2 tablespoons oat flour or gluten free baking flour
  • 1 tablespoon unsweetened cocoa powder
  • Pinch of sea salt

Optional Add-ins

  • 2 teaspoons chocolate chips (divided, 1 tsp to mix in, 1 tsp to sprinkle on top)

Instructions

  1. Whisk: In a 10-12 oz microwave-safe mug, whisk together the egg, milk, and maple syrup until fully combined.
  2. Mix: Add the chocolate protein powder, oat flour, cocoa powder, and a pinch of sea salt to the wet mixture. Fold everything together gently until just combined. Then fold in 1 teaspoon of the chocolate chips.
  3. Cook: Microwave the mug on HIGH power for 90 seconds. Carefully remove it from the microwave—it will be hot. Check the cake’s texture; it should be firm and spring back when pressed lightly.
  4. Serve: Let the mug cake cool for 1-2 minutes. Top with the remaining chocolate chips, fresh berries, or whipped cream if desired. Enjoy immediately for best texture and flavor.

Notes

  • Use a microwave-safe mug to avoid any damage or accidents.
  • Substitute oat flour with gluten-free baking flour to make it gluten-free.
  • Adjust microwave time based on your microwave’s wattage; reduce time if it starts to overcook.
  • Maple syrup can be replaced with honey or agave syrup.
  • For a vegan version, substitute the egg with a flax egg and use a plant-based milk.
  • Adding a pinch of salt helps to balance and enhance the chocolate flavor.
