Ingredients

1 large banana
1 large egg
1 tablespoon peanut butter
1 tablespoon maple syrup
⅓ cup oat flour
1 teaspoon baking powder
¼ teaspoon ground cinnamon
pinch of salt

Instructions

Place the peeled banana in a large microwave-safe mug (16-ounce or larger) and use a fork to mash until smooth.
Add in the egg, peanut butter, maple syrup, flour, baking powder, cinnamon, and a pinch of salt. Stir well until the mixture looks like a lumpy cake batter. Sprinkle a few chocolate chips or walnuts on top, if you'd like extra texture.
Place the mug in the microwave and cook on high power for 2 minutes. The cake will rise above the top of the mug as it cooks, but it shouldn't spill over as long as you use a 16-ounce or larger size mug. The cake should feel firm to the touch in the center when it's done cooking; add another 30 seconds of cook time if you need to.
Carefully remove the mug from the microwave (it will be hot!) and let it cool for 5 minutes before digging in.

Notes

Nutrition information is for a single serving without the optional toppings. This information is automatically calculated and is just an estimate, not a guarantee.

Oven Directions: Preheat the oven to 350ºF. Place the oven-safe mug on a baking sheet for easy removal (this will ensure the mug doesn't tip over on a wire shelf). Bake for 35 minutes, or until a toothpick comes out clean from the center of the cake. Let it cool for 5 minutes before serving.

Mug Cake for Two: If you want to make a snack-size portion or have smaller mugs to work with, divide this batter into two 10-ounce coffee mugs and cook them simultaneously for 2 minutes in the microwave.

Update Note: This recipe was updated in July 2023 to use a microwave and turn out more like banana bread. Find the original recipe here if you prefer the flourless oven-baked version, which does not work in a microwave.
