I saw the recipe on FB a while ago and just last week decided to try it. It's super easy, called "3,2,1 cake".
Get a box of Angel food cake mix, a box of any other flavor and mix them up well. I just poured both of them in a big ziplock bag.
Then you take three tablespoons of mix, two tablespoons of water and put it in the microwave for one minute. 3,2,1.
It's spongy, but it has a good flavor, I made an orange flavored mix and a devil's food mix.
I'm going to give some to my mother-in-law, I bet she'd like it.
