Whipped Marshmallow Frosting

Ingredients
- 2 1/2 cups granulated sugar
- 2/3 cup water
- 6 egg whites, room temperature
- 1/2 tsp. cream of tartar
- 2 tsp. vanilla extract
- 1/2 tsp. fine sea salt
- 1 vanilla bean, seeds removed
Directions
- Place the sugar, water, egg whites and cream of tartar in a glass or heat proof bowl that will fit over a double boiler. Beat the mixture, off the heat, with a hand mixer until white and foamy, about 1 minute. 
- Place the bowl on top of the double boiler, on low heat, and beat on high for about 10 minutes until it is light, fluffy and stiff peaks form. 
- Remove from heat and add the vanilla extract, salt and vanilla bean seeds. Beat for another 2-3 minutes to thicken even more. - Scoop into a pastry bag fitted with a large round tip or frost using an off-set metal spatula. - Recipe Adapted from the cookbook Cupcakes! by Elinor Klivans
