Microwave cake

One day, my mom sent me an email about a recipe. The recipe allows you to bake a cake in your micorwave in about 5 miunutes. I'm like "HELL YES!" Cake all the time and with easy access??? Sweet :) So I've tried it today just for the hell of it. The recipe is pretty simple. Here are my steps and result:

4 tablespoons of flour
4 tablespoons of sugar
2 tablespoons od cacao (mix well)

1 egg
3 tablespoons of milk
3 tablespoons of oil
dash of vanilla
3 minutes in the microwave

End result. Well yes it lokks like rubber. I have to say, I didn't mesure the oil and milk well. I also used peanut oil, because I only had that. But still eatable, but the not the best. Must retry in the futur.
