Never Fail Marshmallow Frosting

I made some vanilla cupcakes the other day and tried a new frosting recipe. It doesn't say it's '7 minute' frosting, but it looks very much the same as other recipes I've seen. It's also very similar to how to make marshmallows, but they have gelatin, but this frosting doesn't. This is very easy and like the recipe says, it's 'never fail' -- always a good thing in my book. For these cupcakes, I used a piping bag.

Fluffy White Marshmallow Frosting

(makes enough for 18-24 cupcakes)

1 cup sugar

1/4 tsp. cream of tartar

1/3 cup water

Pinch of salt

2 egg whites

1 tsp. vanilla

Mix first four ingredients in a small saucepan and bring to a boil. Pour over egg whites, add vanilla and beat on high speed until stiff peaks form. (It may seem to take a long time, but keep beating and you'll notice the change.)
