For the frosting, i didn't want to use just a regular buttercream and i remembered seeing a recipe using marshmallow fluff so on Cakecentral i found a peanut butter marshmallow buttercream. The frosting was sooo good it was hard to stop eating it, and the peanut butter was not overpowering at all, it had just the right amount of sweetness.
This recipe is a keeper!!
(Bruna, that is the towel your mom made for us under the cupcake, we use it for everything!!)
