1 lg. angel food cake
1 qt. (approximately) sherbet or ice cream (lime is pretty for Christmas)
1 lg. carton Cool Whip

Split cake crosswise, making 3 layers. Spread softened sherbet (or ice cream) on bottom layer; place next layer on top; spread with more sherbet (or ice cream) and top with the remaining layer. Frost completely with Cool Whip. Decorate with cherries if desired. Store in freezer.

The cake will slice beautifully if removed from freeze about 15 minutes before serving.
