Family and the folks from church love this cake from Ann Byrn (The Cake Mix Doctor). I've made it many times and experimented with different pan sizes. I've listed my results below so you can choose to make it "moist and gooey" or with a firmer cake base (my preference). Slicing the apples takes some time, but since the recipe uses a cake mix, it goes together faster than you think! This was a "hot item" when sold at a church bake sale (sold in disposable pans).
