How to Make Marshmallow Sauce

  1. In a medium saucepan, combine 1 cup granulated sugar, ½ cup light corn syrup, and ½ cup milk. Stir over medium-low heat until the sugar dissolves completely.
  2. Bring the mixture to a rolling boil, then reduce heat and simmer for exactly 5 minutes, stirring occasionally.
  3. Meanwhile, in the top of a double boiler (or a heatproof bowl set over a pan of simmering water), combine 10 ounces (about 2 cups) mini marshmallows, 2 tablespoons unsalted butter, and 2 tablespoons of water. Stir frequently until the marshmallows are completely melted and smooth.
  4. Gently pour the hot syrup from the saucepan into the melted marshmallow mixture, stirring constantly with a whisk or spatula until well combined and smooth.
  5. Stir in 1 teaspoon pure vanilla extract.
  6. To reheat, gently warm the sauce in the top of a double boiler or in the microwave in short bursts, stirring frequently until smooth.
  7. Beat the sauce well before serving for a light and airy texture.
