  • ½ overripe banana
  • 2 tablespoons powdered peanut butter (i.e. PB2)
  • 1 tablespoon whole wheat flour
  • ¼ teaspoon baking powder
  • ¼ teaspoon cinnamon
  • Pinch salt
  • ½ tablespoon maple syrup
  • 1 tablespoon 1% milk (or milk alternative*)
  • ½ tablespoon dark chocolate chips


  • Place the half of the overripe banana in the mug. Use a fork to mash well.
  • Add the powdered peanut butter, flour, baking powder, cinnamon, salt, maple syrup, and milk. Stir together until well combined. Fold in the chocolate chips.
  • Place the mug in the microwave and cook for 45-60 seconds, or until the top of the cake does not appear damp. Do not overcook.
  • Let cool for a few minutes, then enjoy! Feel free to add a dollop of vanilla ice cream or Greek yogurt on top if you’d like.


  • *This works best with a very overripe banana – one with lots of brown spots or starting to turn black. If your banana is only slightly overripe (i.e. a few brown spots), it will not provide as much moisture. As such, you may need to increase the milk to 2 tablespoons in that situation.
  • Freeze the remaining half of the banana to use in smoothie recipes.
