Ingredients
Method
- Preheat oven to 350°F (180°C). Grease an 8-inch square pan. In a large bowl, whisk the sweet potato, oil, both sugars, eggs, and vanilla until smooth.
- Sift the flour, cocoa, baking soda, and salt over the wet mixture. Fold until just combined, then stir in the chocolate chips.
- Pour the batter into the pan, sprinkle top with extra chocolate chips if desired, and bake 30 to 35 minutes, until a toothpick has moist crumbs.
- Cool in the pan 10 minutes, transfer to a rack, and cool completely before slicing.
Notes
Use cooled, fully mashed sweet potato. The cake is even better the next day; store it covered at room temperature overnight or in the fridge for longer storage.
