After baking the cake, cool in the pan for 15 minutes, then poke holes in the cake with a fork every 1/2 inch. Stir together one 3-ounce package strawberry Jell-O and 1 cup boiling water for two minutes. Add in 1/2 cup cold water, then pour the Jell-O mixture over the cake. Keep the cake refrigerated for at least three hours, then top with one 8-ounce package Cool Whip.
