My favourite method for cooking sweet potato is to use my Instant Pot. Simply add unpeeled sweet potato to the basket. Add 1 cup of water and pressure cook on high for 12 minutes. The peel comes off very easily with your fingers after cooking.
Or bake sweet potato in a 425 F oven for 45 -60 minutes.
Preheat oven to 350°F (175°C). Grease an 8x8 inch baking pan with a touch of avocado oil or line it with parchment paper for easy removal.
In a large mixing bowl, mash the cooked sweet potato until smooth.
Add the eggs, maple syrup, cocoa powder, natural peanut butter, and vanilla, chocolate chips (optional) to the bowl with the sweet potato. Mix well until all the ingredients are thoroughly combined.
Gradually add the coconut flour to the mixture, stirring until it forms a thick batter. The coconut flour will help bind the ingredients together and absorb any excess moisture.
Once the batter is well combined, pour it into the prepared baking pan, spreading it out evenly with a wooden spoon or spatula.
Bake the brownies in the preheated oven for 30-35 minutes, or until the edges are set and a toothpick inserted into the center comes out clean.
Remove the brownies from the oven and allow them to cool in the pan for at least 10 minutes before slicing and serving.
