Mix the two cake mixes in a large zip top bag or the container of your choice. One mix MUST be angel food. When someone wants cake put 3 tablespoons of the mix into a coffee mug. Add 2 tablespoons of water. Stir until all the mix is moistened. Place in the microwave and cook for 1 minute on high. Turn onto a small plate and top with whipped topping if you choose. Or sprinkle with a little powdered sugar. Or do as my oldest does and add a scoop of ice cream. Mmmmmmm, warm cake, cold ice cream. Enjoy!
