Ingredients
Method
- Preheat the oven to 350F and line an 8x8 pan with parchment.
- Mash the banana with the sweet potato, then whisk in the brown sugar, eggs, and butter.
- Stir in the flour, cocoa, and baking soda until just combined.
- Fold in the chocolate chips and spread into the pan.
- Bake 28 to 32 minutes and cool before slicing.
Notes
The riper the banana, the less added sugar you'll need.
