What Is a Chocolate Mug Cake?
A mug cake is a single-serve cake made directly in a mug and cooked in the microwave. The batter comes together in minutes and bakes in about 60–90 seconds. The result? A warm, fluffy, perfectly portioned chocolate cake whenever the craving hits.

How to Make a Chocolate Mug Cake

Step 4: Microwave for 60–90 seconds, until the cake has puffed up and is mostly set on top. (Microwave times vary, so keep an eye on it!)
