1 cup butter, softened
1/4 teaspoon salt
1 (32-oz.) package powdered sugar
6 to 7 Tbsp. milk
1 tablespoon vanilla extract
Beat butter and salt at medium speed with an electric mixer 1 to 2 minutes or until creamy; gradually add powdered sugar alternately with 6 Tbsp. milk, beating at low speed until blended and smooth after each addition. Stir in vanilla. If desired, beat in remaining 1 Tbsp. milk, 1 tsp. at a time, until frosting reaches desired consistency.
