This particular “mug cake” uses only a banana for sweetness, with no added flours or sugars. The result is a truly delicious, and guilt-free treat!
- 1 very ripe banana (with brown spots!)
- 2 Tablespoons natural peanut butter, or nut butter of choice
- 1 whole egg
- ¼ teaspoon baking soda
- dash of cinnamon (optional)
