For the days when you want an impressive but quick sweet treat, a mug cake delivers a cozy, single portion. Baking chocolate cake batter in the microwave instead of a conventional oven allows you to enjoy a homemade dessert in just minutes. In this extra-rich recipe, which makes two cakes, devils food cake meets a peanut butter cup. The cakes don’t rise all the way to the top of the mug, giving you ample room to scoop on some vanilla ice cream and your favorite toppings, like crunchy flaky sea salt and chopped roasted peanuts.
Notes from the Food & Wine Test Kitchen
We tested these cakes in 900W and 1250W microwaves. Cooking times may vary for different microwave models; use cooking times and doneness qualifiers as guides to adjust accordingly.
If you have an instant-read thermometer, insert it into the center of a cake. The center should register around 190°F to 200°F. If you prefer a gooier, more batter-like texture, feel free to “bake” in the microwave for a shorter period of time.
