What You Need
3 packages (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 pure vanilla extract
1/2 cup powdered sugar
1/2 cup cornstarch
What You Need
Lightly grease a 9×13-inch baking pan and dust it with a mixture of powdered sugar and cornstarch. This will prevent the marshmallows from sticking.
In the bowl of a stand mixer, combine the gelatin and 1/2 cup of cold water. Allow it to sit while you prepare the sugar syrup.
In a medium saucepan over medium heat, combine the granulated sugar, corn syrup, salt, and the remaining 1/2 cup of water. Stir until the sugar dissolves, then insert a candy thermometer. Allow the mixture to come to a boil without stirring. Let it reach 240°F (soft-ball stage).
With the stand mixer on low speed and the whisk attachment in place, slowly pour the hot sugar syrup into the gelatin mixture. Once combined, gradually increase the speed to high and whip for 10-12 minutes, until the mixture becomes thick and glossy.
Add the vanilla extract during the last minute of whipping, ensuring it’s well incorporated.
Pour the marshmallow mixture into the prepared pan, spreading it evenly. Allow it to sit uncovered at room temperature for at least 4 hours or overnight until set.
Combine equal parts powdered sugar and cornstarch on a cutting board. Turn the marshmallow slab onto the board and cut it into squares using a sharp knife or cookie cutter. Coat each piece in the sugar-cornstarch mixture to prevent sticking.
