Ingredients
Method
- Place the banana in a 12-ounce microwave-safe mug and mash until smooth with a fork.
- Add the egg, melted butter, and vanilla, and stir until fully combined.
- Sprinkle in the flour, sugar, baking powder, and salt, and gently fold just until no dry streaks remain. Fold in chocolate chips if using.
- Microwave on high for 1 minute (adjust for wattage), until the top is set but the center is slightly glossy.
- Let it rest 1 minute, then top with whipped cream or extra chocolate chips and enjoy warm.
Notes
The cake tastes best right after it cools for a minute, when it’s still soft and steamy. If you want a drier, more bread-like texture, microwave for an additional 10 to 15 seconds, but keep an eye on it so it does not dry out.
