Try this: follow this recipe Chocolate Cake In 5 Minutes! It will take you the same amount of time to make a bowl of cereal, which is to say, no time at all!
And while the cake is baking in the microwave, make a cup of coffee, tea, or whatever your favourite beverage is that goes with chocolate cake. No sooner will you have your drink that you will hear the “ding!” of the microwave!
The other great thing about this is that you can have your cake, eat it, and then not have more slices in the fridge to tempt you. (Ok, that is a rationalization, I know, but it works for me.)
You need to have a recipe like this around. Trust me! 🙂
P.S. You need the cake flour for the rising action. But it’s easy enough to get a small bag. It’s worth it.
