1/2-3/4 lb. (2 or 3 sticks) butter, room temperature,1 lb. (2 cups) confectioner's sugar,1/2 tsp. vanilla,16 oz. tub of marshmallow cream (I recommend Fluff)
Cream the butter (I love my Kitchenaid!) on high until it's light and fluffy. Add the confectioner's sugar, 1/4 cup at a time, and beat until fluffy each time. Beat in the vanilla until incorporated. Then dump in the Fluff and mix it up 'til it's all creamy. Transfer to pastry bag (if desired) and pipe onto cupcakes! (You can also cut the corner off a Ziploc bag and use that instead.)
Then sprinkle with graham cracker crumbs. and top with a square (rectangle actually, I guess) of a Hershey's chocolate bar.
Are you a princess? I said & she said I'm
much more than a princess, but you don't have a name for it yet here on
earth.
