Easy microwave mug cake recipe for chocolate lovers

We know we aren’t the only ones who love something sweet with a cup of tea or coffee while winding down after a day at work. But what do you do when the craving hits and you have nothing sweet at home? A chocolate microwave mug cake is the answer! This easy, quick recipe with ingredients you probably have in your kitchen will easily satisfy any sweet or chocolate craving.

What is a chocolate microwave mug cake?
As the name suggests, a chocolate microwave mug cake is a little chocolate cake you make in a mug and ‘bake’ in the microwave. It can also be made in another container, like a bowl or dish, if you prefer.


  • ¼ cup flour
  • ¼ cup sugar
  • 2 tablespoons cocoa powder (unsweetened cocoa powder is best)
  • ¼ teaspoon bicarbonate of soda
  • Pinch of salt
  • 2 Tbsp. milk
  • 2 Tbsp. vegetable or canola oil
  • ¼ tsp. vanilla essence
  • 2 Tbsp. water
  • Chocolate chips (optional)

Cooking Instructions
After measuring all the ingredients, combine the wet and dry ingredients in a bowl/container. Line your mug with oil and then pour the mixture into the mug. Pop it in the microwave for 60 to 90 seconds, let it cool for a few minutes, and enjoy!

Your microwave’s wattage affects the cooking time and heating time. For example, the Hisense 30l Mirror Microwave Oven has a 900W microwave power output, which means you’d likely be able to cook a microwave mug cake in 60 seconds. The Hisense 26lt Electronic Mirror Microwave Oven, which is cheaper, has an 800W microwave power output, which means it would take a bit longer.

Topping or Extras
If you want to make your chocolate microwave mug cake special, you could add a bit of icing on top, a scoop of ice cream, fresh fruit, or even a chocolate spread. For a gooey centre, put a spoon of chocolate spread in the centre of the mixture before cooking it in the microwave.

A Healthier Version
If you want a healthier alternative to this quick sweet treat, or a version that suits your dietary requirements, we’ve got you covered. For vegans, you can substitute milk with a plant-based milk. If you’d prefer a gluten-free chocolate microwave mug cake, rather use an oat flour or gluten-free all-purpose flour. Nut lovers could also add chopped nuts into the mixture before cooking.
