Incredible Chocolate Sweet Potato Cake

Preheat oven to 350°F. Line a 9-inch round or 8-inch square silicone or other nonstick cake pan with parchment paper. For frosting, in a blender or food processor combine sweet potato, coconut sugar, unsweetened cocoa powder, cashew butter or almond butter, plant-based milk, vanilla extract, and sea salt. Cover and blend until very smooth, scraping sides as needed. If necessary, add 2 to 3 tablespoons of milk and 1 to 2 tablespoons of coconut sugar to make desired consistency and sweetness. Cover and chill until ready to use. For cake, in a blender combine sweet potato, maple syrup, vinegar, vanilla, and ½ cup water; cover and blend until completely smooth. In a large bowl stir together flour, coconut sugar, chocolate chips, and salt. Sift in cocoa powder, baking powder, and baking soda. Add sweet potato mixture to flour mixture. Use 1 tablespoon water to rinse blender to remove any remaining puree and add to flour mixture. Mix just until well incorporated. Transfer batter to prepared pan. Bake 21 to 23 minutes. Cool in pan on a wire rack. Remove cake from pan and top with frosting. Prep-time: 20 MINUTES / Ready In: 40 MINUTES Makes 18 to 20 onion rings Serving size: ¼ of recipe
