Mix the cake according to the box directions. Pour into the Pampered Chef Deep Dish covered baker. Scoop out spoonfuls of frosting and drop on batter, spacing as you go, and using about half of the container of frosting.Cook covered approx. 10 minutes. When done cooking, frost cake warm with remaining frosting.
I am a purist and dont have a lot of kitchen gadgets or specialty items, so I use a regular square glass pan then dot with frosting mix+instant pudding mix for same effect. I use my own cocoa frosting from back of cocoa box. Fewer non-food additives and much cheaper per recipe
