The Best Way To Make Mug Cakes


  1. In a mixing bowl, mix the flour, sugar, butter, eggs, vanilla essence, and lemon zest together until you get a smooth batter.
  2. Transfer the mixture to a well-greased, medium-sized microwave-resistant dish (we used a 0.8-litre dish).
  3. Microwave the mixture for 3-4 minutes (we made this sponge in an 800W microwave in 3 minutes) until the sponge has risen and is fully cooked. You can check by inserting a skewer in the middle of the sponge – it should come out clean.
  4. Leave the sponge to rest while you place the lemon curd in a microwave-safe dish and heat it for 30 seconds. Stir it until it’s glossy and soft, then generously spread it on top of your sponge before serving.


In just a few simple steps, you can create a delicious and fluffy lemon sponge cake that’s perfect for a quick dessert. This recipe is easy to customize and is sure to be a hit with family and friends. So why not try it out today and enjoy the sweet and tangy flavors of this delightful dessert!
