A very tasty, very easy peanut butter frosting ( needs refridgerating) is about a cup of peanut butter and a pkg of instant vanilla pudding blended with about a half a cup of cold milk. This works with either a 13x9 cake or a layer cake, depending on how thick you frost it you may need to double the recipe for a layer cake. I have used this on chocolate cake and it was delish!!!
