Donut Mug Cake

Prep Time: 4 minutes
Cook Time: 1 minute
Total Time: 5 minutes
Course: Dessert
Cuisine: American
Servings: 1 mug cake
This single serving mug cake tastes just like baked old fashioned donuts or the baked donut muffins that became popular a few years ago. But instead of having to make an entire batch, you can make an individual one in just minutes.


  • 3 tbsp granulated white sugar
  • 6 tbsp all purpose flour
  • 1/2 tsp baking powder
  • 1/16 tsp ground nutmeg this looks like a very small amount, but please do not omit this!
  • 1 3/4 tbsp vegetable oil
  • 3 tbsp low fat or fat free milk
  • 1/4 tsp vanilla extract

Chocolate ganache frosting (optional)

  • 1/4 cup semisweet chocolate chips
  • 2 tbsp boiling heavy cream


  1. In a microwave-safe mug (at least 8 oz or more. I used 8 oz mugs and the cakes rose exactly to the top), add all ingredients. Mix with a mini whisk until batter is smooth. Cook cake in microwave at full power about 1 minute 30 seconds or until top of cake is done. Let cake cool a few minutes before eating or decorating. Cake is best consumed soon after it is cooked or it will start to dry out, so if you are planning on decorating, do not wait too long.

  2. If desired, use a cupcake corer to remove some of the center of your cake, creating a donut appearance. I only cored out half rather than having the hole go straight to the bottom. For a cinnamon sugar finish, lightly brush the surface with butter and then sprinkle sugar and cinnamon.

  3. To make ganache frosting, add boiling heavy cream to chocolate chips and whisk until smooth and glossy. If your chocolate is not completely melted, microwave briefly for about 10 seconds and then try to whisk again until smooth and glossy. The chocolate ganache should be thick but slightly running, making it easy to spread on the donut cake.
