Add all ingredients to a bowl. Mix together until smooth and combined using a spatula.
Add batter in an even layer to an 8x8 baking dish lined with parchment paper.
Bake brownies for 30-40 minutes, until a toothpick comes out clean.
I like to top my brownies with some chocolate chips and flaky salt as soon as they come out of the oven. This way the chocolate melts. Let brownies cool completely for at least an hour to set. Slice and enjoy.
Notes
*I baked mine in the oven for about 50 minutes at 425 degrees the night prior. You can bake the sweet potato several days in advance if desired.
