  • 1/2 cup butter softened.
  • 1/2 cup shortening.*
  • 3/4-1 cup powdered sugar.
  • 1 marshmallow cream.** 13 oz
  • 1 1/2 teaspoon vanilla extract.***


  • Cream butter and shortening with an electric mixer on medium until fluffy.
  • Gradually add the confectioners' sugar, about 1/2 cup at a time.
  • Add vanilla extract and mix.
  • Fold the marshmallow creme into the frosting until incorporated.
  • Makes enough to generously frost 24 cupcakes.


* You can use butter instead of shortening, but shortening makes it more firm to be used in decorating.
** I’ve started with 7oz jar then tasted and kept adding marshmallow cream until I was satisfied with the taste.
*** You can also use almond extract.
*** To make Mocha Marshmallow frosting, add cocoa in with the powdered
sugar and a bit of espresso powder.
