Recipe: Microwaved mug cake

So sometimes you really just want a dessert for one. Especially being a student it can be hard to make a whole cake that you want to keep to yourself but then actually have to struggle to eat the whole thing (unless you freeze it but frozen/thawed cake is never the same). Plus this way, you get a freshly ~zapped cake every time.

It takes less than 5 minutes or as much as you want in order to add things/make it fancy.

For this mug cake, I decided to make a peanut butter chocolate cake. You can get creative, even put in chocolate bits, crushed up candy bars, M&M’s, candy, etc. With my version, it’s also vegan friendly!

Makes: 1


  • 4 tablespoons plain flour
  • 4 tablespoons sugar (I have vanilla-scented sugar from a vanilla pod that I keep in my sugar – makes everything way more delicious).
  • 2 tablespoons cocoa powder
  • 3 tablespoons oil (I used a flavourless one i.e. canola)
  • 3 tablespoons water (or milk/soy milk)
  • 1 teaspoon peanut butter
  • A dash of salt (because salt tastes great with chocolate!)


  1. Mix dry ingredients together in a mug.
  2. Add oil and water. Stir until it forms a paste. Make sure you get all the dry ingredients, no one likes clumps of flour at the bottom!
  3. Stir in peanut butter. (It’s also a good arm workout!)
  4. Microwave mug for 2-3 minutes. At 2 minutes you should test your cake either with a skewer or if lazy, just touch the top – it should spring back when cooked. Mine took about 2.5 minutes.
  5. Dust with icing sugar if desired. Would be really lovely with a scoop of ice cream on top.


Some people use egg in their recipes but I find that the oil is a good substitute and is sufficient enough to bind everything.

When microwaving the cake will sort of billow out but it deflates when you take it out. Water molecules being vibrated and all. I’m not going to discuss how a microwave works. I hate physics.

If you grease up the sides, you’ll probably even be able to turn it out and decorate to serve to guests etc. Which means it could be a very good dessert idea for lazy cooks, last minute guests, etc. Alternatively, use a microwavable ramekin.
