These vegan sweet potato brownies are fudgy, deeply chocolatey, and made with just six simple ingredients. Gluten-free and oil-free, they taste so indulgent that no one will believe there's a vegetable inside.
Preheat the oven to 180°C (350°F). Line a brownie tin with parchment paper.
Add the mashed sweet potato, maple syrup, peanut butter, coconut flour, melted dark chocolate, and salt to a blender or food processor. Blend on high until the batter is completely smooth. Alternatively, mash the sweet potato very thoroughly and mix all ingredients in a large bowl until no lumps remain.
Pour the batter into the prepared brownie tin and spread evenly. Bake for 40–45 minutes, until a toothpick inserted in the center comes out with just a few moist crumbs. Do not overbake.
Remove from the oven and allow to cool in the tin for at least 15 minutes before slicing and serving.
