7-Minute Marshmallow Frosting Recipe


  • 1 1/2 cups granulated sugar
  • 1/4 teaspoon cream of tartar
  • 1/8 teaspoon salt
  • 1/3 cup water
  • 2 egg whites
  • 1 1/2 teaspoons vanilla extract

Tools Needed:

  • Double boiler
  • Handheld electric mixer


  1. Prep the Stage: Combine the granulated sugar, cream of tartar, salt, water, and egg whites in the top part of a double boiler. Don't have a double boiler? No worries, just place a heat-proof bowl over a pot of boiling water; it works just as well.

  2. Beat It Just Right: Grab your handheld electric mixer and beat the mixture gently for about 1 minute just to get them acquainted.

  3. The Boil Is Key: Heat some water in the bottom part of your double boiler until it’s nicely boiling. Position the top pan with your mixture over this boiling madness. Make sure the water isn’t touching the bottom of your mixing bowl – that’s crucial to prevent graininess.

  4. Time to Whisk: With the heat on, beat the egg white mixture with your mixer at high speed. Keep at this for exactly 7 minutes—a stopwatch or kitchen timer is your best friend here. Yes, keep beating continuously; think of those perfect peaks!

  5. Vanilla Twist: Once your timer dings at 7 minutes, pull the mixture off the heat and quickly stir in the vanilla extract.

  6. Cool Down: Let the frosting cool slightly for about 10 minutes. It's best to use this gorgeous fluff immediately to frost your cakes or cupcakes for optimal spreading ease.

And there you have it, a luscious marshmallow frosting ready in about the time it takes to pick a movie on Netflix. Go ahead, give it a try. It’s guaranteed to elevate your desserts from simple to spectacular. Plus, who can resist that marshmallow charm?
