Chocolate mug cakes are what I call chocolate cake in a mug. They are a single-serving cake. The quickest and easiest dessert you can make when you want chocolate cake in a moment.

They are perfect for any sweet occasion such as Valentine’s Day or when you have unexpected friends coming or maybe when you are craving something sweet after dinner and don’t want to bake an entire cake.

What mug size to use:

You want to use a large (14 oz) mug or (12 oz) ramekin to prevent overflowing as the cake will rise quite high during cooking before sinking back down.

TIPS to get best results for this MUG CAKE:

  • Mix the batter well until there are no clumps
  • The cook time will vary according to your microwave – check after 50 seconds then pop it back in the microwave in 10 second increments if not done – do not overcook or the mug cake will be dry
  • Lightly coat the mug or ramekin with ghee or baking spray if you decide to bake the mug cake in the oven.

Follow these tips for best result:

  • Preheat the oven to 350 degrees F. Mix all the ingredients together in a medium bowl or measuring cup.
