Marshmallow Fluff Ingredients

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

Instructions

  1. Prepare Egg Whites: Place the egg whites and cream of tartar in the bowl of a stand mixer or a large mixing bowl. Set aside to be whipped later.
  2. Make Sugar Syrup: In a small saucepan, combine the granulated sugar, light corn syrup, and water. Heat over medium heat, stirring occasionally, until the mixture reaches 245°F (soft-ball stage) on a candy thermometer.
  3. Whip Egg Whites: While the sugar syrup is heating, beat the egg whites and cream of tartar on medium speed until soft peaks form.
  4. Combine Syrup and Egg Whites: Lower the mixer speed to low. Slowly drizzle the hot syrup into the whipped egg whites in a thin, steady stream, being careful not to let the syrup touch the whisk or sides of the bowl.
  5. Whip to Stiff Peaks: Increase the mixer speed to high and whip for 7–9 minutes until the mixture thickens, becomes glossy, forms stiff peaks, and the bowl cools to the touch. Then, beat in the vanilla extract for 30 seconds to blend thoroughly.
  6. Store or Use: Use the marshmallow fluff immediately or transfer it to an airtight container and store it in the refrigerator for up to 2 weeks.

Notes

  • Ensure egg whites are at room temperature for better volume when whipped.
  • Use a candy thermometer for precise syrup temperature at 245°F (soft-ball stage).
  • Be cautious when pouring hot syrup into egg whites to avoid splashing or cooking the egg whites prematurely.
  • Store in an airtight container to maintain freshness and prevent drying out.
  • Can be used as a filling, topping, or in various dessert recipes.
