• Granulated sugar - 2 cups
• Light corn syrup - 1 cup
• Salt - ¼ teaspoon
• Vanilla extract - 1 tablespoon
• Confectioners' sugar - ½ cup

Instructions

1. 1.

   In the bowl of a stand mixer, sprinkle gelatin over 1/2 cup of cold water to soften.

2. 2.

   In a small saucepan, combine granulated sugar, corn syrup, salt, and remaining 1/2 cup of cold water.

3. 3.

   Heat over medium-high, stirring until sugar dissolves, then stop stirring and allow to boil until the mixture reaches 240°F on a candy thermometer.

4. 4.

   Remove from heat and slowly pour the hot syrup into the softened gelatin with the mixer on low speed.

5. 5.

   Increase speed to high and whip until the mixture is very thick and fluffy, about 10 minutes.

6. 6.

   Add vanilla extract and mix until incorporated.

7. 7.

   In a small bowl, mix confectioners' sugar and cornstarch. Lightly grease a 9x13 inch baking dish and dust with some of the sugar-starch mixture.

8. 8.

   Pour marshmallow mixture into the prepared dish, spreading evenly, and dust the top with more sugar-starch mixture.
