Marshmallow Fluff Ingredients

  • 1/3 cup water
  • 3/4 cup sugar
  • 3/4 cup light corn syrup
  • 3 large egg whites (room temperature)
  • 1/2 teaspoon cream of tartar
  • 1 teaspoon vanilla extract

Instructions

  1. Prepare Sugar Syrup: Combine the 1/3 cup water, 3/4 cup sugar, and 3/4 cup light corn syrup in a medium heavy-bottom saucepan fitted with a candy thermometer. Place the pan over medium-high heat without stirring, allowing the mixture to bubble and cook until it reaches 240°F.
  2. Whip Egg Whites: While the syrup cooks, place the 3 large egg whites and 1/2 teaspoon cream of tartar in the bowl of a stand mixer fitted with the whisk attachment, or use a large mixing bowl with an electric hand mixer and whisk. Whip the egg whites to soft peaks, approximately 3 to 4 minutes.
  3. Combine Syrup and Egg Whites: When the sugar syrup reaches 240°F, remove it from heat. Slowly and steadily pour the hot syrup into the egg whites while the mixer is running on medium speed. This step may require assistance if using a hand mixer.
  4. Whip to Finish: Once fully combined, increase the mixer speed to medium-high. The mixture will initially deflate but then thicken again. Continue whipping for 7 to 8 minutes until thick and glossy.
  5. Add Flavor: Whisk in 1 teaspoon vanilla extract to flavor the marshmallow fluff.
  6. Cool and Store: Allow the mixture to cool completely before use. Store the marshmallow fluff in an airtight container at room temperature for up to 2 weeks.
  7. Enjoy and Share: Once you’ve tried this recipe, feel free to share your feedback or star rating!

Notes

  • Ensure egg whites are at room temperature for better volume and stability when whipping.
  • Use a candy thermometer to accurately measure the temperature of the sugar syrup to prevent crystallization and ensure proper texture.
  • Be cautious when pouring hot syrup into egg whites to avoid splashing and burns.
  • Store fluffy marshmallow spread in an airtight container to maintain freshness.
  • This homemade fluff can be used as a topping for desserts, in sandwiches, or as a dip.
