Human: I need to know how to make a homemade ice cream cake. Assistant: 
To make a homemade ice cream cake, you will first need to prepare the cake batter and bake it in a 9x13 inch pan. Once the cake is cool, you can then prepare your favorite flavor of ice cream. Spread the ice cream on top of the cooled cake and freeze for at least 4 hours or overnight. When ready to serve, slice and enjoy!
