Ingredients

  • ½ cup banana puree (from about 1 large or 2 small bananas)
  • cup natural peanut butter
  • 1 egg
  • ½ tsp ground cinnamon
  • 1 tsp baking powder
  • 2-3 tbsp chocolate chips plus more to sprinkle on top (optional)

Instructions

  • Preheat the oven to 350 degrees F (180 degrees C).
  • Add the banana puree, peanut butter, egg, cinnamon, and baking powder to a bowl and mix until well combined.
  • Fold in the chocolate chips until incorporated.
  • Pour this mixture into a parchment paper-lined loaf pan. Use a spatula to flatten and smooth out the top. Sprinkle a few extra chocolate chips on top.
  • Bake for 25 minutes, or until the edges are golden brown.
  • Allow it to cool completely before slicing it into bars.

Notes

  • Use overripe bananas for the best natural sweetness.
  • Make sure to use natural peanut butter that contains only peanuts (or peanuts and salt) as the ingredients.
  • I used a 9 by 5 loaf pan for this recipe. Feel free to double the ingredients to make enough to fill a brownie pan!
  • Add in extra add-ins for more texture and taste! Crushed nuts are a great mix-in option for added texture!
