Method
- Pierce the sweet potato several times with a fork.
- Microwave on HIGH for 5 to 9 minutes, turning it halfway through, until very tender.
- Cool and peel the sweet potato.
- Mash until smooth, then measure 1 cup.
- Heat the oven to 350°F.
- Grease a 9-inch square baking pan.
- In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
- In a large bowl, whisk together 1 cup mashed sweet potato, the eggs, maple syrup, canola oil, buttermilk, and vanilla extract.
- Add the flour mixture to the sweet potato mixture and stir just until no dry streaks remain.
- Spread the batter evenly in the prepared pan.
- Bake for 30 to 36 minutes, until a toothpick inserted in the center comes out with a few moist crumbs.
- Cool the cake in the pan for 20 minutes.
- Transfer it to a wire rack and cool completely.
Notes
For the best texture, measure 1 cup of the mashed sweet potato after cooking and mashing. Refrigerate covered for up to 4 days; freezer-friendly. A 1-to-1 gluten-free flour blend may work as a swap, though the texture can vary.
