These flourless peanut butter banana brownies are so easy to make, gluten free and baked with a tasty peanut butter swirl! Perfectly fudge, rich and made in one bowl.


  • 2 ripe bananas, mashed
  • 1 cup (250g) natural smooth peanut butter
  • 2 large eggs
  • 1/3 cup honey (or maple syrup)
  • 1 teaspoon vanilla extract
  • 1/2 cup cocoa powder
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1/2 cup dark chocolate chips
  • Extra peanut butter to swirl (optional) 


  1. Preheat the oven to 160C/ 325F. Line a 23cm/ 8×8 inch brownie pan with baking paper.
  2. In a large bowl mash the bananas then add the peanut butter, honey, eggs and vanilla, and mix until combine.
  3. Add the cocoa powder, baking powder and salt, and mix until just combined. Fold in the 1/3 cup of chocolate chips.

  5. Bake for 25-30 minutes or until toothpick comes out clean. Allow it cool in the pan for 15 minutes before slicing. Enjoy!
