This easy chocolate mug cake recipe is the perfect quick fix dessert. No need to make an entire cake with the satisfying single-serving treat.


  • 3 tablespoons all purpose flour
  • 1 1/2 tablespoons cocoa powder
  • 1/2 teaspoon baking powder
  • 3 tablespoons sugar *
  • 1 egg yolk
  • 4 tablespoons milk (cow or plant milk)
  • 1 tablespoon oil (olive oil or canola oil)
  • 1/4 teaspoon pure vanilla extract


Add the wet ingredients to a large microwave safe mug. This includes the egg yolk, milk, oil and vanilla.

Add the dry ingredients. This includes the flour, cocoa powder, baking powder and sugar.

Mix well. Make sure there are no dry bits of batter on the bottom of the mug.

Microwave. This mug cake cooks for me in 2 minutes, but the time may vary depending on the strength of your microwave. I’d start with 1 minute 45 seconds and then check the cake. It is done when it has risen nicely and is firm on the top when you press it gently with your finger. (Careful, it will be hot.)

Cool and serve. Let the mug cake cool for a few minutes. It will be very hot! Then add your favorite toppings. I’m always partial to caramel sauce, sprinkles, ice cream or chocolate sauce. 


* When I make this cake for myself, I use 2 tablespoons of sugar. But when I make it for kids or for someone with a bigger sweet tooth than me, I use 3 tablespoons of sugar.
