Ingredients

Scale
  • 1 scoop (about 30g) vanilla or chocolate protein powder (whey or plant-based)
  • 3 tbsp (23g) all-purpose flour (or oat flour for gluten-free)
  • 1/4 tsp baking powder
  • Pinch of salt
  • 1 large egg (room temperature)
  • 2 tbsp (30ml) milk (dairy or non-dairy)
  • 1 tbsp (15ml) melted butter or coconut oil
  • 1/2 tsp vanilla extract
  • 12 tbsp (12-24g) granulated sweetener (sugar, stevia, monk fruit, or erythritol)
  • 1 tbsp (10g) mini chocolate chips or berries (optional)
  • 1 tbsp nut butter (peanut or almond, optional)
  • Pinch of cinnamon or cocoa powder (optional)

Instructions

  1. Lightly grease the inside of a microwave-safe mug (12-16 oz) with melted butter or oil.
  2. In the mug, whisk together protein powder, flour, baking powder, and salt until well combined.
  3. Add the egg, milk, melted butter or coconut oil, and vanilla extract. Whisk until the batter is smooth and no streaks remain.
  4. Stir in sweetener and any optional mix-ins (chocolate chips, berries, nut butter, cinnamon).
  5. Microwave on high for 60-90 seconds. Start with 60 seconds, then check. If needed, microwave in 15-30 second increments until the cake is set.
  6. Let the mug cake cool for 1-2 minutes before eating.
  7. Top with yogurt, whipped cream, nut butter, or extra chocolate chips/berries if desired.

Notes

Do not overmix the batter to keep the cake fluffy. Use a wide mug for best results. Adjust microwave time based on your microwave’s wattage. For vegan, use flax egg and plant-based protein powder. For gluten-free, use oat or almond flour. Mix dry ingredients in advance for quick prep. Cake is best enjoyed fresh but can be stored in the fridge for up to 24 hours.
