Preheat your oven to 325 F. Line an 8x8 inch brownie pan with parchment paper or spray with coconut oil or grease with butter.
In a large bowl mash your bananas. Add the peanut butter, maple syrup, egg, cacao powder, vanilla, baking soda and salt to the bowl. Mix until just combined. Fold in the 1/2 cup of chocolate chips.
Transfer the batter to your prepared pan and spread out evenly with a rubber spatula. Toss some extra chips on the top for aesthetics.
Bake for 25 minutes or until toothpick comes out clean. Allow it to cool in the pan for 15 minutes prior to removal. Place on wire rack for minimum 1 hour or over night in a tupper.
Notes
You can substitute the bananas with 3/4 cup pumpkin puree.
You can substitute the peanut butter with almond butter or any nut or seed butter.
You can substitute the maple syrup with honey or agave.
These are very GOOEY. Add 1/4 cup almond flour to thicken them up and keep them flourless OR add 1/4 cup regular flour.
