How to Make Marshmallow Fluff

  1. In a clean, grease-free bowl, beat 3 large egg whites with 1/2 teaspoon cream of tartar using an electric mixer until light and frothy.
  2. With the mixer running on low speed, gradually add 2 tablespoons of granulated sugar, beating until soft peaks form.
  3. In a small saucepan, combine 1/3 cup water, 1/2 cup light corn syrup, and 2/3 cup + 2 tablespoons granulated sugar.
  4. Cook over medium heat, stirring constantly, until the sugar dissolves and the mixture comes to a rolling boil.
  5. Continue cooking, without stirring, until the mixture reaches the firm-ball stage (240°F on a candy thermometer), about 6-8 minutes. Be careful not to burn.
  6. Immediately remove the syrup from the heat.
  7. With the mixer running on low speed, slowly pour the hot syrup into the beaten egg whites, being careful to avoid splashing.
  8. Increase the mixer speed to high and beat for 5 minutes, until the mixture is thick, glossy, and has increased in volume.
  9. Add 1 teaspoon vanilla extract and continue beating on high speed for another minute until the mixture resembles marshmallow cream.
  10. Pour the marshmallow fluff into a clean glass jar with an airtight lid. Store at room temperature.
