Ingredients
Scale
- 1 medium ripe banana (about 120g or 4.2 oz), mashed
- 1/4 cup (30g or 1.06 oz) self-rising flour
- 1 large egg, room temperature
Instructions
- Lightly grease the inside of a microwave-safe mug with butter or neutral oil.
- Peel and mash the ripe banana directly in the mug using a fork until mostly smooth with a few small lumps.
- Crack in one large egg and stir thoroughly until combined and slightly frothy.
- Add 1/4 cup self-rising flour and stir gently until no dry flour remains. Batter should be thick but spoonable; add a teaspoon more flour if too runny.
- Microwave on high for 90 seconds. Check at 75 seconds to avoid overcooking. The top should spring back when lightly touched and a toothpick inserted should come out mostly clean.
- Let the mug cake rest for 1-2 minutes to firm up.
- Enjoy warm straight from the mug or tip out onto a plate.
Notes
Use very ripe bananas with brown spots for natural sweetness and moisture. Adjust microwave time by 10-second increments based on your microwave’s power. Grease the mug to prevent sticking. Optional add-ins include cinnamon, nutmeg, walnuts, chocolate chips, or gluten-free flour substitutions.
