Line an 8x8 baking pan with parchment paper. Preheat the oven to 350° F.
In a large bowl whisk all the dry ingredients together: almond flour, baking powder, baking soda, cocoa powder, brown sugar, and salt.
Add the wet ingredients into the dry mixture. Use a spatula to mix everything together. When the mixture is thoroughly combined, fold the chocolate chips into the batter.
Pour the batter into the parchment-lined 8x8 baking dish.
If making sweet potato swirls, combine the almond butter and mashed sweet potato in a small bowl. Place spoonfuls of the mixture into the brownie mixture, making sure to leave spaces. Take a butter knife and carefully make circles and swirls into the brownies to spread the mixture and make a swirl design.
Bake for 28-30 minutes, or until a toothpick comes out clean.
Remove from oven and allow the brownies to cool for 2-3 minutes. Grab the outsides of the parchment paper to remove from the baking dish. Slice and enjoy!
