After baking...
Allow the cake to cool inside the spring form pan and spray another cake pan with nonstick spray.
Pour in your remaining batter and bake until done.
Allow both layers to cool completely.
With a cup full of warm water, place your spatula in the warm water.
Let your ice cream sit until it is slightly softened.
Begin spreading ice cream on your pineapple/cherry layer of cake while in the
spring form pan.
