1/2 cup (1 stick/4 oz./113g) butter
1/2 cup milk
2 cups sugar
dash of salt
1 teaspoon vanilla extract
Melt the butter over low heat in a heavy saucepan. Stir in the milk, sugar and salt. Raise heat to medium, bring mixture to a full, rolling boil, and boil for 2 minutes. Remove from heat. Add vanilla and do not stir. Allow to cool. (Don't stir, now.)
When mixture is cool (bottom of pan will be barely warm to the touch), beat by hand or with an electric mixer until frosting is creamy and thick enough to spread.
Makes enough to frost an 8 or 9-inch 2 layer cake.
