Mickey Marshmallows

1. Combine the gelatin with ½ cup cold water in a heat-safe bowl. Set aside.
2. Combine the sugar, corn syrup, salt, and ½ cup water in a small saucepan and cook over medium heat until sugar dissolves.
3. Raise the heat to high and cook until the syrup reaches 240 F. Remove from heat.
4. Beating on low, slowly pour the sugar syrup into the gelatin. Turn the beaters to high and beat until very thick, about 15 minutes. Add the vanilla extract and mix thoroughly.
5. Stift powdered sugar into a 8x12 glass baking dish. Pour the marshmallow into the dish, smoothing the top. Sift more powdered sugar on top of the marshmallow.
6. Let sit uncovered overnight.
7. Once the marshmallow is set, turn it out onto a cutting board and cut into Mickey shapes using a small Mickey shaped cookie cutter.
