I slice my apples into 9x13 pan with cinnamon, a little lemon juice, and vanilla. Take a white cake mix and mix in a stick of melted butter. This will form a crumble for the top. I dot with butter and bake for about an hour. Sometimes I go ahead and put the apples in while the oven is heating. I mix up the crumble and clean up the kitchen for a little while to let the apples start to bake. Just to make sure they are done. The crumble doesn't take as long as the apples. I don't like biting into a hard apple piece in my pie. I have used canned filling too but it isn't as good. I added caramel the last time and everyone liked that. I even tinted the crumble orange and green for Halloween. Made it look moldy.lol
