Why Marshmallow Frosting? Marshmallow frosting stands out for its light and airy texture, reminiscent of fluffy marshmallows. It’s not only delicious but also versatile, making it a perfect addition to a wide range of desserts. From classic vanilla cakes to chocolate cupcakes, marshmallow frosting can elevate your creations to new heights.

  • 3 large egg whites
  • 3/4 cup granulated sugar
  • 1/4 teaspoon cream of tartar
  • 1 teaspoon vanilla extract


  1. Prepare a Double Boiler: Fill a saucepan with a few inches of water and bring it to a simmer over medium heat. Place a heatproof bowl over the simmering water, ensuring that the bottom of the bowl doesn’t touch the water.
  2. Whisk Egg Whites: In the heatproof bowl, whisk together the egg whites, granulated sugar, and cream of tartar. Continue whisking constantly until the sugar is dissolved and the mixture is warm to the touch, about 3-4 minutes.
  3. Beat Until Stiff Peaks Form: Transfer the mixture to a stand mixer or use a hand mixer. Beat on high speed until stiff peaks form and the mixture is glossy and thick, about 7-10 minutes. Be patient, as this step is crucial for achieving the desired fluffy texture.
  4. Add Vanilla Extract: Once stiff peaks have formed, beat in the vanilla extract until well combined. Your marshmallow frosting is now ready to use!
