All ya do is mix one chocolate cake mix with one angel food cake mix. Shake them up in a big ziplock bag. Then when you are ready to make yourself a cake combine 3Tbsp of cake mixture with 2 Tbsp of water in a coffee mug. Microwave for 50 seconds. Turn mug over and let cake drop out onto plate.
This recipe would be excellent with Cool whip, unfortunately I didn't have any when I took this picture.
Try it! It's great!
