Marshmallow Frosting

**Update- It's probably the egg whites but this frosting was only good for the first couple hours, so I will not make this again unless I am serving it immediatly.
I love to bake but I wouldn’t consider myself a baker. I pass over any recipe that requires yeast, I always use boxed cake mix, and I refuse to make anything that takes longer than an hour. So it is always a challenge when I go looking for dessert recipes. I saw a recipe for Marshmallow Frosting/7-minute frosting that I couldn’t resist! You have to mix for a good 7-8 minutes but it was easy and SO delicious! It really did taste like fluffy marshmallow cream!

Ingredients
2 large egg whites
1/2 cup sugar
1/4 cup light corn syrup
2 tablespoons water
1 1/2 teaspoons pure vanilla extract

Directions
Combine frosting ingredients with a pinch of salt in a metal/glass bowl set over a saucepan of simmering water and beat with a handheld electric mixer at high speed until frosting is thick and fluffy, 6 to 7 minutes. Remove bowl from heat and continue to beat until slightly cooled. Mound frosting on top of cake.
