Sweet Potato Brownie

1 Preheat oven to 350°F and line an 8x8 baking pan with parchment paper.
2 In a mixing bowl, combine mashed sweet potato, nut butter, maple syrup, and vanilla extract. Stir until smooth.
3 Add cocoa powder, salt, baking powder and almond flour. Mix until fully combined and no lumps remain.
4 Spread the batter evenly into the prepared pan.
5 Sprinkle chocolate chips on top, if using.
6 Bake for 25 -30 minutes, or until the edges are set and the center is soft but not wet.
7 Let cool completely before slicing. The brownies will firm up as they cool.
