Ingredients
  

Main Ingredients
  • 1 scoop protein powder 25-30g, whey or plant-based
  • 2 tbsp mashed banana very ripe works best
  • 2-3 tbsp milk any type - oat, dairy, almond, soy
Optional
  • 1 pinch baking powder for extra fluffiness

Equipment

  • Microwave-safe mug
  • Fork or small whisk
  • - Measuring spoons

Method
 

  1. In a microwave-safe mug or small bowl, add 1 scoop protein powder, 2 tbsp mashed banana, and 2 tbsp milk. Stir until you get a smooth batter. If too thick, add 1 more tbsp milk. If too runny, add a bit more protein powder. Optional: add a pinch of baking powder for extra fluffiness.
  2. Microwave on high for 45 to 60 seconds. Check the center—if it's still wet, microwave for 10-15 seconds more. Do not overcook—the center should be just set and spongey. Timing varies by microwave power.
  3. Let the mug cake rest for 1 minute before eating for better texture and safety. The cake will continue to set during this time. Enjoy warm!

Notes

Pro Tips: Use very ripe bananas with brown spots for maximum sweetness. Room temperature ingredients blend more easily. Start with less milk and add gradually to achieve the perfect consistency. Variations: Add cocoa powder for chocolate version, vanilla extract for vanilla cake, or fresh berries for fruity twist. Storage: Best enjoyed fresh but can be stored covered in refrigerator for up to 2 days. Reheat for 15 seconds before serving.
