Banana mug cake is a moist, fluffy and super easy mug cake recipe that takes under 5 minutes to make. Make this cozy banana bread mug cake for the perfect single serve dessert.
Grab your favorite mug. It should hold at least 8 oz. (240 ml) of liquid. Melt one tablespoon of butter in the mug. This takes about 20-30 seconds in the microwave.
If there is any liquid at the bottom or the cake seems underbaked in the center or bottom of the mug, heat the mug cake in the microwave in additional 20 second increments until the cake is to your desired consistency.
