Ingredients

  • 1 cup white granulated sugar
  • ⅛ teaspoon salt
  • 4 egg whites
  • 1 teaspoon vanilla extract

Instructions

  • Use a double boiler or fill a pot with an inch or two of water and add a heat proof mixing bowl to create a double boiler.
  • On low heat, add sugar, salt, and egg whites, whisking continuously until the sugar dissolves and the mixture is hot to the touch (about 5 minutes).
  • Pour mixture into large mixing bowl or stand mixer and add vanilla. Beat on high until stiff peaks form, about 7 minutes.
  • Spoon marshmallow icing onto cooled cupcakes.
  • Optional: Toast marshmallow under your stove's broil setting for 30 seconds, or using a torch.
