How to Neatly Cut the Cake
Make sure cake is chilled before serving. Then, use a serrated knife dipped in hot water to cut the cake, carefully wiping blade with clean damp towel between cuts to prevent the filling from building up on the blade.
Prepare cakes as directed; cool completely. Tightly wrap each layer in plastic wrap and freeze up to 2 weeks. When ready to serve, thaw cakes at room temperature before preparing COOL WHIP mixture and using to frost cakes.
How to Use Leftover Gelatin
Dissolve each of the 4 remaining gelatin mix flavors in 1 cup boiling water, using separate bowl for each flavor. Pour half of each flavor gelatin into one of 8 small dessert dishes. Refrigerate until firm. Top with additional thawed COOL WHIP Whipped Topping just before serving. Makes 8 servings.
