Nadine, I just cleaned this morning! I microwave a mug of water 3-5 minutes to power steam everything loose. The cake is my reward for scrubbing and waxing and powerbuffing the kitchen floor.
I will cut back to cook time a little bit to get it moister. Next time.
It took 8 minutes because I had to hunt for the new can of cocoa. I also added about a half teaspoon of baking powder.
I will always blame Davaroo for this. Always. It took longer to post all this than make it. One dirty mug, fork and measuring spoon. I have a tummy ache from wolfing down...
