First, make your mix! In a large bowl mix the angel food cake mix powder and the any flavor cake mix. I mix it with a wire whisk. Be careful or you will have a cloud of powder in the air. When well mixed, place all of the powder in a gallon size resealable bag. Mark the following directions on the bag with a Sharpie marker. 3 Tablespoons mix, 2 Tablespoons of water, 1 minute in the microwave.
