Ingredients

Scale

Liquid Ingredients

  • 1/3 cup water
  • 3/4 cup light corn syrup
  • 1 teaspoon vanilla extract

Dry Ingredients

  • 3/4 cup granulated sugar

Egg Whites

  • 3 large egg whites (room temperature)
  • 1/2 teaspoon cream of tartar

Instructions

  1. Prepare the Sugar Syrup: Combine the water, granulated sugar, and 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: In the bowl of a stand mixer fitted with the whisk attachment or a large mixing bowl with an electric hand mixer, whip the egg whites and cream of tartar on medium speed until soft peaks form, approximately 3-4 minutes.
  3. Combine Syrup with Egg Whites: Once the syrup reaches 240°F, remove it from heat and very slowly pour it in a steady stream into the whipped egg whites while mixing on medium speed. If using a hand mixer, having an extra person to help with pouring is recommended.
  4. Whip Until Thick: After fully combining, increase the mixer speed to medium-high. The mixture may deflate at first but will thicken again. Continue whipping for 7-8 minutes until glossy and thick.
  5. Add Vanilla: Whisk in the vanilla extract until fully incorporated.
  6. Cool and Store: Let the marshmallow fluff cool completely before use. Transfer it to an airtight container and store at room temperature for up to 2 weeks.
  7. Enjoy and Share: Use your homemade fluff as a topping or ingredient, and be sure to share your feedback in the comments or star ratings!

Notes

  • Use room temperature egg whites for optimal volume when whipping.
  • Do not stir the sugar syrup as it cooks to prevent crystallization.
  • If the syrup reaches temperature too quickly, reduce heat to avoid burning.
  • The fluff will thicken significantly after adding the syrup and whipping – patience is key.
  • Store marshmallow fluff in an airtight container at room temperature; refrigeration can alter the texture.
  • Double the recipe for larger batches, but ensure you have a large enough mixing bowl and saucepan.
