Description

This Marshmallow Frosting is a light, fluffy, and glossy topping perfect for cakes and desserts. Made with egg whites, sugar, and a hint of cinnamon and vanilla, it delivers a classic, sweet, and smooth texture that enhances any dessert with a marshmallow-like flavor.


Ingredients

Marshmallow Frosting Ingredients

  • 4 large egg whites
  • 1 cup granulated sugar
  • Pinch of kosher salt
  • 1 teaspoon vanilla extract
  • Pinch of ground cinnamon (optional)


Instructions

  1. Prepare a Double Boiler Setup: Bring 1 inch of water to a simmer in a pot. This will be used to gently heat the egg white mixture without direct contact with the heat to prevent cooking the eggs.
  2. Combine Ingredients and Heat: In the bowl of your stand mixer, add egg whites, granulated sugar, and a pinch of kosher salt. Whisk together to combine, then place the bowl over the simmering water, ensuring the bowl fits tightly and the bottom does not touch the water. Heat the mixture while whisking frequently.
  3. Monitor Temperature: Continue whisking until the mixture reaches 120°F on a candy thermometer or feels hot to the touch. This step ensures the sugar dissolves completely and the eggs are heated safely.
  4. Whip the Frosting: Remove the bowl from heat and place it in the base of your stand mixer fitted with the whisk attachment. Beat the mixture on high speed until it becomes cool, thick, and glossy.
  5. Add Flavorings and Finish: Add the vanilla extract and a pinch of ground cinnamon if desired. Beat again to incorporate these flavors evenly into the frosting.
  6. Use the Frosting: Spoon the finished marshmallow frosting into a large piping bag fitted with your choice of tip for decorative frosting, or simply mound it on top of your dessert, such as cheesecake, for a delightful presentation.

Notes

  • Ensure the bowl does not touch the simmering water to prevent scrambling the egg whites.
  • The temperature of 120°F is critical for safety and to achieve the correct frosting texture.
  • The pinch of cinnamon is optional but adds a warm spiced note to the frosting.
  • Use immediately or store covered in the refrigerator for up to one day. Re-whip before use if refrigerated.
  • This frosting is not fully cooked, so avoid serving to individuals sensitive to raw egg whites.
