What you will need
This recipe uses 6 simple ingredients that you can find at any grocery store:
- 0.5 medium very ripe banana mashed
- 4 tbsp all-purpose flour
- 2 tbsp brown sugar
- 2 tbsp melted butter
- 0.25 tsp ground cinnamon
- 1 tbsp chopped walnuts
Step by step instructions
Step 1: Mash the Banana
Mash the ripe banana directly in a large microwave-safe mug until it forms a nearly smooth puree with only small lumps remaining.
Step 2: Mix in Remaining Ingredients
Add the flour, brown sugar, melted butter, and cinnamon to the mashed banana and stir until a thick batter forms.
Step 3: Fold in Walnuts
Stir in the chopped walnuts, distributing them evenly through the batter.
Step 4: Microwave and Serve
Microwave on high for 80 to 90 seconds until the top is set and slightly springy. Rest for 30 seconds then eat directly from the mug.
Easy substitutions

- chopped walnuts → chocolate chips or pecans
- melted butter → coconut oil for a dairy-free version with a slight tropical flavor
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Using an underripe banana does not provide enough natural sweetness or moisture for the proper texture
- Not mashing the banana thoroughly enough leaves dense chunks that create uneven cooking in the microwave
