Preheat oven: Preheat your oven to 350°F (175°C) and grease or line an 8×8-inch square baking pan with parchment paper.

1. Prepare sweet potato: Peel and chop the sweet potato into cubes. Steam or boil the sweet potato until soft, then mash it until smooth. You’ll need about 1 cup of mashed sweet potato.
2. Mix ingredients: In a large mixing bowl, combine the mashed sweet potato, almond butter, cocoa powder, maple syrup, vanilla extract, salt, and baking powder. Stir until well combined.
3. Add coconut flour: Add the coconut flour to the mixture and stir until the batter is smooth. If the batter is too thick, add a tablespoon of water or milk to help loosen it up.
4. Fold in chocolate chips: Fold in the chocolate chips, if using, for extra richness and texture.
5. Bake: Pour the batter into the prepared baking pan and spread it evenly. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs. Be careful not to overbake, as this can cause the brownies to dry out.
6. Cool and serve: Allow the brownies to cool in the pan for at least 10 minutes before transferring them to a wire rack to cool completely. Slice and serve!
