Seven Minute Frosting is an old-fashioned recipe that should never go out of style. It's sweet. It's fluffy. It's a veritable cloud of a frosting. Even better, you need just a handful of pantry ingredients and about 7 minutes to make this recipe.
In a large mixing bowl, combine 8 oz granulated sugar, 4 large egg whitesm ½ teaspoon cream of tartar, and ¼ teaspoon table saltSet the bowl over a pan of barely simmering water, making sure the bottom of the bowl doesn't touch the water. Whisk the egg whites until the temperature reaches 160°F.
Remove the bowl from the heat and add 1 tablespoon vanilla extract. Whip the whites on high speed until stiff peaks form and the whites are cooled. About 4-5 minutes.
Use immediately as the frosting will stiffen upon standing.
Notes
If you use pasteurized egg whites from a carton make sure the package says they can be used for meringue. Some markets sell pasteurized eggs still in the shell, those can also be used for this recipe.
