Pour cheesecake in the prepared pan. Place cake pan into a larger cake can or casserole dish.

Place a spoonful of frosting onto the cake plate. This will help keep the cake from shifting while you decorate. Use a serrated knife to cut the domes off the cakes. Place one cake layer on the cake, then cover the top with about 1 cup of frosting.
Take the cheesecake out of the pan by lifting the aluminum foil. Remove the foil and place it on top of the cake. Spread another 1 cup of frosting on top of the cheesecake.
Add the last cake layer and do a crumb coat over the whole cake.
