Easy Mug Cake

The first time I heard of mug cake I was beyond myself in excitement. A cake which is ready in 2 minutes in a microwave sounded too good to be true…. In a way it was, as all the recipes I tried ended up in an uneatable mess. I had completely given up on mug cakes but recently I gave it another go and discovered a brilliant recipe. This one is so light and spongy! I love it and can’t have enough of it now.

mug cake

  • 40g oats, ground. Grind the oats using a blender. (Use gluten free oats if you have coeliac disease)
  • 1 tablespoon sugar
  • 1 teaspoon baking powder (Use gluten free oats if you have coeliac disease)
  • 1/2 of an unripe banana, mashed
  • 2 tablespoon lactose free milk of choice
  • 2 egg whites
  • 1 teaspoon vanilla paste or extract (optional)


  1. Mix the oats with the baking powder and sugar.
  2. Add the remaining ingredients and mix everything together until you have a smooth batter.
  3. Grease a mug with a little bit of oil.
  4. Pour the mixture into the mug. The batter should fill 3/4 to 7/8 of the mug. Cook in a microwave on high for approximately 2 to 2 1/2 minutes.
  5. I love serving mine with some fresh blueberry puree.

I received some questions regarding the mug cake so here are some further tips:

  • The oats don’t need to be ground very finely. Here’s a picture of what mine looked like.ground oats
  • The cake will just slide out of the mug if you oil it a little.
  • Choose the right sized mug to ensure it cooks properly. The batter should fill 3/4 to 7/8 of the mug.
