A very simple icing perfect for piping on top of cupcakes.
  • 3 sticks (12 oz) unsalted butter, softened
  • 1/2 cup confectioners' sugar
  • 1 teaspoon of vanilla extract
  • 16 oz of Marshmallow Fluff or Marshmallow Creme.
  1. In the bowl of a stand mixer, beat the butter until creamy. Add the sugar and beat until creamy, then add the vanilla.
  2. Add the Marshmallow Fluff (or Marshmallow Creme) and beat until fluffy.
  3. Put in a piping bag and pipe on top of cupcakes
  4. In my opinion, it worked the best on cupcakes. It was fine on a layer cake, but the texture isn't as smooth when spread and it seems to work better when piped out in dollops.
If you're making a small batch of cupcakes or just want to ice 12, scale the recipe down and use 1 stick butter, 2 tablespoons plus 2 teaspoons of sugar, and a dash of vanilla. Weigh out 5 1/3 ounces of marshmallow creme using a scale.
