This easy-to-make Fluffy Marshmallow Frosting is spreadable, pipe-able and all around shiny and lovely!


  • 4 large egg whites
  • 1 cu granulated sugar
  • 1/4 teaspoon cream of tartar
  • 1/4 teaspoon salt
  • 1 teaspoon vanilla


  1. Add the egg whites, granulated sugar, cream of tarter, and salt to a heat-safe bowl of an stand mixer. Set the bowl over a saucepan crammed with a few inches of simmering water.
  2. If you aren’t using a stand mixer, use any large heat-safe bowl, with high sides for mixing.
  3. Heat the mixture, whisking continuously until the egg whites are warm to the touch and sugar has dissolved, about 3 – 4 minutes.
  4. Remove the bowl from the heat and transfer to your stand mixer fitted with the whisk attachment. Mix on high speed, until stiff, shiny peaks form, about 7-9 minutes. Add the vanilla during the last 10 seconds of mixing.
  5. Spread or pipe onto cake instantly.


Best if used instantly.
