Fudgy protein brownies are much healthier than regular brownies, are made with simple ingredients, while still being filled with a rich chocolate flavor.
Preheat the oven to 350 degrees F. Line a square 8x8 brownie pan with parchment paper or lightly grease it with oil.
Add mashed banana, nut butter, cocoa powder, oat or almond flour, protein powder, vanilla extract, and salt to a large bowl. Mix until evenly combined. Fold in the chocolate chips.
Pour brownie batter into your pan. Spread across the pan in an even layer.
Bake brownies for ~40 minutes. After, remove from the oven and allow brownies to cool completely. Slice and enjoy!
