1 box Cake Mix 3 lbs Ricotta cheese 8 Eggs 1 tbs Vanilla 3/4 cup Sugar Cinnamon and Sugar mixture for topping Preheat oven to 350 Prepare cake mix as directed Pour cake mix into 13x17 pan Mix Ricotta cheese, eggs, vanilla and sugar together Pour and spread mixture over top of cake mix Bake at 350 for 1/2 hour Sprinkle top with sugar and cinnamon mixture Bake until cake is done - test with toothpick When this cooks, the cake comes to the top, and the cheese goes to the bottom, so testing with a toothpick works. But, if you touch the cake it will seem to be undone as the cheese on the bottom will be VERY soft until the cheesecake cools down. I burnt mine once cause of that! The secret is, once the cake tests done, turn off the oven and let it sit for about ten minutes
