  • Use a fork to stir together all ingredients except the chocolate chips in a 10 to 12 ounce microwave-safe mug.
  • Microwave on high until a toothpick inserted in the center comes out clean, about 1 minute 45 seconds. Pause cooking once halfway through and open the microwave door to prevent the cake from overflowing.
  • If desired, sprinkle the chocolate chips on top. Serve the mug cake while it's still warm.


  • Don't over-mix the batter! Like any cake, over-mixing will make it tough and rubbery instead of moist and fluffy.
  • Amp up the flavor. If you have instant espresso powder on hand, add 1/4 teaspoon of it to this recipe. It will help pull out the flavor notes in the chocolate.
  • Serve it how you like it. This cake is moist and delicious on its own, but you can serve it any way you like your chocolate cake! A few topping ideas are: chocolate chips, vanilla ice cream, whipped cream, or fresh sliced strawberries.
