Homemade Marshmallows

1 cup powdered sugar, for dusting
2 cups white granulated sugar
1 Tbsp light corn syrup
1 1/4 cups water, divided
1/4 cup unflavored beef gelatin
2 egg whites, room temperature
1 tsp vanilla extract
Lightly spray a 9x9 inch baking dish with vegetable oil spray and generously dust with powdered sugar. Set aside.
In a medium saucepan (ideally with tall sides) over medium-high heat, stir together white sugar, corn syrup and 3/4 cup water. Heat to 250° - 265° degrees F (121° - 129° degrees C), or until a small amount of syrup dropped into cold water forms a rigid ball.
While syrup is heating, place remaining 1/2 cup of cool water in a small metal mixing bowl and sprinkle gelatin over the surface. Place bowl over double boiler or set in pan of very hot tap water. Stir occasionally until gelatin has dissolved completely. Keep warm until syrup has come to temperature.
Remove syrup from heat and whisk a small amount of the gelatin mixture into hot syrup. Syrup will bubble and froth significantly; stir gently until settled. Continue to add gelatin mixture until fully combined. Set aside to cool slightly.
In bowl of powerful standing mixer, whip egg whites to soft peaks. Slow beater to medium and pour syrup mixture into egg whites in a thin stream. Add vanilla. Once all ingredients are incorporated, beat on high speed until the egg whites are very stiff (10-12 minutes; watch your mixer to prevent overheating or motor damage!). Spread evenly in prepared pan, cover with cling wrap, and let rest 8 hours or overnight.
To cut, loosen edges of marshmallow sheet and turn out onto cutting board. Slice into squares or rectangles with a serrated or bread knife, cleaning blade in between with very hot water. Shake marshmallows in ziplock bag with additional powdered sugar to coat cut edges. Seal bag and store up to 1 month.
I think I saw somewhere a recipe that added coffee to marshmallows, so there's an option for caffine addicts. And your basic marshmallow recipe is the base for nougat, so if you ever want to try making your own candy bars there's an option, too. (I'm happy to taste test any attempted candy bars!)
