  • Mixing Bowls
  • 8×8 Pan
  • Oven


  • 2 mashed ripe bananas
  • 2 eggs
  • 1/4 cup maple syrup
  • Tsp vanilla
  • 1/4 cup creamy pb + 2 tbsp for topping
  • Tsp baking powder
  • 1/4 cup cocoa powder
  • 1 1/4 cup oat flour
  • Optional 1/4-1/2 cup choc chips
  • Pinch of salt


  • Preheat oven to 350F
  • Mash bananas well and whisk together with eggs, maple, vanilla, and peanut butter until your mixture is smooth.
  • Add baking powder, salt, and oat flour and mix until fully combined and no lumps remain. Add chocolate chips if desired (or you can add nuts, etc).
  • Pour brownie mixture into a parchment-lined 8×8 pan.
  • Microwave 2 tbsp of peanut butter for 10 seconds so it’s a bit runny. Dollop on top of brownie mixture and use a knife to swirl.
  • Bake for 40-50 min for a cakey texture, less if you like them fudgy, but a toothpick some come out relatively clean
  • Cool for at least 20 min before slicing and enjoy! I love to top these with a little bit of flaky sea salt for some sweet and salty action – highly recommend!
