My sister is coming to visit me and we'll be celebrating a belated "half-birthday". That means half a layer cake (I've halved a recipe and will cut the single layer in two to make the layer cake). Does anybody have a good PB frosting recipe? Also, how far ahead of time can I make this? I'd like to make it Sunday to frost and serve on Tuesday afternoon (because of work, etc, the "etc" being cleaning, vacuuming, dusting).
And the recipe should be able to frost/fill HALF of a 9-in layer cake, so I assume this would be a standard recipe that is easily halved (most frosting recipes are, unlike some cake recipes).
