Prep: 7 min | Cook: 15 min | Total: 32 min

Cost: $4.40 total, $0.73 per serving

Ingredients

  • 2 cups Granulated Sugar (for syrup)
  • 0.5 cup Light Corn Syrup (helps prevent crystallization)
  • 0.25 cup Water (for syrup)
  • 2 teaspoons Unflavored Gelatin (dissolved in water)
  • 4 large Egg Whites (room temperature)
  • 0.25 teaspoon Cream of Tartar (stabilizes egg whites)
  • 1 teaspoon Vanilla Extract (flavor)

Instructions

  1. Measure and Prepare Ingredients

    Gather all ingredients, measure them into separate containers, and set the mixing bowl aside.

    Time: PT2M

  2. Bloom the Gelatin

    Sprinkle the gelatin over 2 tablespoons of cold water in a small cup and let it sit for 5 minutes until it swells.

    Time: PT5M

  3. Make the Hot Sugar Syrup

    In the saucepan combine granulated sugar, corn syrup, and 1/4 cup water. Place over medium heat, stir until sugar dissolves, then attach the candy thermometer and bring the mixture to 240°F (soft‑ball stage).

    Time: PT10M

    Temperature: 240°F

  4. Whip Egg Whites to Soft Peaks

    While the syrup is heating, separate the egg whites into the mixing bowl, add the cream of tartar, and begin whipping on medium speed until the whites become foamy and form soft peaks.

    Time: PT5M

  5. Combine Syrup and Egg Whites

    When the syrup reaches 240°F, turn the mixer to high and slowly drizzle the hot syrup into the egg whites in a thin, steady stream, aiming for the side of the bowl to avoid splatter. Continue beating until the mixture becomes glossy and holds stiff peaks.

    Time: PT5M

  6. Add Vanilla

    Add the vanilla extract and beat for another 30 seconds just to incorporate.

    Time: PT2M

  7. Cool and Store

    Transfer the marshmallow fluff to an airtight container. Let it sit at room temperature for a few minutes to set, then refrigerate if not using immediately.

    Time: PT5M
