5Bake in preheated oven for about 1 hour or until a toothpick inserted into the center of the cake comes out clean. Remove from oven and place immediately into the freezer for 45 minutes.
6Meanwhile, make the frosting; In a large bowl, using an electric mixer, cream together 1/2 cup butter and cream cheese until smooth. Add the vanilla and beat until combined.
