  • Candy thermometer
  • Stand mixer


  • 7 large egg whites
  • 2 cups sugar
  • 1 1/2 teaspoons vanilla extract


  • Combine the ingredients in the metal mixing bowl of your stand mixer and set over a pot filled with boiling water on a range, creating a double boiler.
  • Whisk by hand for a few minutes until the mixture reaches 110 F on a candy thermometer.
  • Place the bowl on a stand mixer fitted with the whisk attachment. Whisk on medium speed for 10 minutes.
  • Increase to high speed and whisk until stiff glossy peaks form, about 5 to 10 minutes more.
  • Pipe or spread frosting onto desserts.
  • Using a culinary torch, toast the frosting.
  • Store in the refrigerator until ready to eat - up to 3 days.


  • Make sure the inside of the bowl is totally dry.
  • Make sure there are no egg yolks mixed in with the egg whites.
  • Keep on whisking – don’t stop early.
