Sometimes you just need some chocolate. And sometimes you just need some cake. And you always need simplicity and effectiveness. And that is exactly what this 4-Ingredient Chocolate Microwave mug Cake is: a single-serving, easy-to-make cake packed with chocolate and cooked in the microwave. This cake only takes about two minutes to whip up, and is extremely light and fluffy! Because there is no added oil or butter, this cake is slightly healthier, but also slightly less moist. I would recommend topping this mug cake with frosting, ganache, or whipped cream to add back some richness.
