From what I have read this very simple layered ice cream cake was started by Kraft using crumbed Oreo cookies between the layers. Today the variations are endless, with any size you want, adjusting the ingredients and using any flavor of ice cream and adding what suits you. My version is a small cake layered in a loaf pan with mocha chip ice cream layered between the ice cream sandwiches. I used fresh whipped cream to frost the cake with drizzles of chocolate and chopped heath bars for a Crunch decoration. This cake takes minutes to prepare allowing for freezing and makes pretty slices and is delicious!
