This sweet potato cake is ridiculously moist, perfectly spiced, and topped with a rich coffee icing that makes regular frosting look weak. The natural sweetness from the sweet potatoes balances the bold coffee kick, creating a dessert that feels indulgent but secretly nutritious. No, it won’t turn you into a health guru, but at least it’s not just sugar and regret. Whether you serve it at brunch, dessert, or just eat it straight from the pan, it’s guaranteed to disappear fast. Fluffy, spiced, and draped in coffee magic—this is cake on a whole new level.
