Once the cake has cooled and the whipped cream topping is made, soften 2 pints of ice cream at room temp or with a few short bursts in the microwave
Slice the cooled loaf cake horizontally into 3 equal portions (if the top slice has a tall dome, slice some of it off to create a flat top for decorating)
Lightly grease a loaf pan and line it with sheets of plastic wrap that hang over all four sides enough to completely cover the top of the cake and give you enough to hold onto when it comes time to lift the frozen cake out of the pan
Place the bottom slice of the loaf cake into the base of the pan
Spread a pint of softened ice cream out evenly and then add the middle slice of cake
Gently press the middle cake slice down to evenly press the ice cream out and then add your second pint of softened ice cream and spread it out evenly
Add your top cake slice, press it down lightly and use the excess plastic wrap hanging over the edges to cover the top of the cake completely
Freeze the ice cream cake for several hours or until solid
When ready to decorate and slice, use the plastic wrap to lift the ice cream cake out of the loaf pan (since we greased the pan, it should not stick, but if it does, use a blow dryer to lightly warm the outside of the pan until the cake releases)
Remove and discard the plastic wrap
Top the cake with your whipped cream and garnished with shaved chocolate or sprinkles or both!
Slice and enjoy!
Freeze leftovers tightly wrapped in plastic or in freezer safe airtight containers
