Step-by-step Instructions

1. Generously spray the bottom and sides of a 9×13-inch baking pan with nonstick cooking spray. Dust the pan with a mixture of the confectioners’ sugar and cornstarch so the marshmallows will release easily later. Tip: tap out excess dusting mix so the coating is even.

2. Place the gelatin and 1/2 cup cold water in a stand mixer bowl to bloom while you prepare the syrup. Let it sit undisturbed so the gelatin absorbs the liquid.

3. In a saucepan, combine the remaining 1/2 cup cold water, corn syrup, granulated sugar, and salt. Cook over medium heat, stirring until the sugar dissolves, then bring to a boil without stirring and continue until the mixture reaches 235 to 240°F on a candy thermometer.

4. Remove the saucepan from heat and let the syrup cool for 5 minutes. Slowly pour the warm syrup into the bowl with the bloomed gelatin while the mixer runs on low speed. Pour in a thin, steady stream to avoid splashing and to ensure the syrup incorporates smoothly.

5. After all the syrup is added, increase the mixer speed to high and whip until the mixture becomes thick, glossy, and tripled in volume, about 10 to 15 minutes. The mixture should hold soft peaks when ready.

6. Add the vanilla extract in the last minute of whipping so the flavor stays bright. Mix just long enough to distribute it evenly.

7. Pour the marshmallow mixture into the prepared pan, using a lightly oiled spatula to smooth the top. Let the pan sit at room temperature, uncovered, for at least 6 hours until the marshmallow is fully set.

8. Once firm, dust a cutting board with the remaining confectioners’ sugar and cornstarch mixture, invert the marshmallows onto the board, and cut into squares with a sharp knife or pizza cutter dipped in the dusting mix to prevent sticking.

9. Optionally coat the cut edges lightly in the dusting mixture before storage to keep pieces from sticking together.

Tips, Storage & Variations

• Practical tips: Use an accurate candy thermometer for the syrup. If your kitchen is very humid, set the marshmallows in a lower-humidity room for the best texture. When cutting, lightly oil your knife and dust it between cuts for clean edges.

• Storage: Store marshmallows in an airtight container at room temperature for up to 2 weeks. Keep them separated with parchment paper if stacking.

• Freezing advice: You can freeze the marshmallows in a sealed freezer bag for up to 3 months. Thaw at room temperature in the sealed bag to prevent condensation.

• Flavor variations using existing ingredients only:

  • Omit the vanilla for a neutral sweet marshmallow.
  • Add a little extra vanilla extract for a stronger vanilla flavor.
  • Slightly reduce the salt for a sweeter profile, or keep the salt as written to brighten the flavor.

For creative pairings, try spreading a smear of warm homemade jam on crackers and topping with a toasted marshmallow.
