Want a quick frosting that won't taste like just another spread on can of it?
Once your cake is cool, simply warm up a can of frosting -- not too warm, just warm enough that it is easy to work with -- then put it in a bowl and stir in a container of Cool Whip. Adjust the amount of Cool Whip, using more for a milder frosting and less for a sweeter one. You can use any flavor of frosting you like. (Of course once spread on the cake, the cake will have to be kept in the fridge.)
My family doesn't care much for frosting from a can because it is just so sweet, but everyone who has tried one of my cakes made this way loves it and thinks it's some kind of frosting I made from a recipe that required work. (Smile)
