Homemade marshmallows are soft, fluffy, and far superior to store-bought. With simple ingredients, you can make customizable treats perfect for hot cocoa, s’mores, or snacking.

Ingredients

  • 3 envelopes (21g) unflavored gelatin
  • 1 cup cold water, divided
  • 1 1/2 cups granulated sugar
  • 1 cup light corn syrup
  • 1/4 teaspoon salt
  • 1 tablespoon vanilla extract
  • 1/2 cup powdered sugar
  • 1/2 cup cornstarch

Instructions

  1. Grease a 9×13-inch baking pan and dust it generously with a mixture of powdered sugar and cornstarch.
  2. In the bowl of a stand mixer, combine gelatin with 1/2 cup cold water. Let it bloom for 10 minutes.
  3. In a saucepan, combine granulated sugar, corn syrup, salt, and the remaining 1/2 cup water. Cook over medium-high heat until it reaches 240°F (soft-ball stage).
  4. With the mixer on low, slowly pour the hot syrup into the bloomed gelatin. Once added, increase speed to high and whip for 10–15 minutes, until thick, glossy, and tripled in volume.
  5. Add vanilla extract during the last minute of mixing.
  6. Quickly pour the mixture into the prepared pan and smooth the top with a greased spatula.
  7. Let it sit uncovered at room temperature for at least 4 hours, or overnight, to fully set.
  8. Dust a surface with powdered sugar and cornstarch. Turn marshmallows out, cut into squares with a greased knife, and coat all sides in the sugar mixture.
