Make A Surprisingly Moist Microwave Sponge Cake

Make A Surprisingly Moist Microwave Sponge Cake

Cooking cakes in a microwave isn’t a new ideas before, but they often turn out with a somewhat unusual texture. Instructables user jessyratfink claims to have figured out how to overcome that problem with a delicious five-minute sponge cake recipe. Amusingly, the idea is lifted from Masterchef Australia:

This is absolutely, 100% the best microwave cake I have eaten in my life.* It takes 5 minutes to throw together and it tastes like sugar cookies and the texture is like REAL CAKE. I was watching Masterchef AU last night and Matt Preston was making a microwave sponge cake that involved passionfruit pulp for the liquid in the recipe. I was instantly excited. It looked great, and I needed it!

After quite a bit of experimentation, she settled on this recipe:

  • 50g melted butter
  • 50g sugar
  • 50g flour
  • 1/2 teaspoon baking powder
  • 1 egg
  • 2 tablespoons milk

This makes two microwave sponge cakes. Just pour half into a ramekin greased with cooking spray, cover with plastic wrap poked with breathing holes, and microwave for 50-60 seconds. When finished you’ve got cake! For the full how-to, check out the post over at Instructables.

  • This is outrageously good as a midnight snack. Just made it myself, needed 10 more seconds for me, which is of course down to the different models of microwaves.
