In a 5-quart mixer add the butter and using a paddle attachment, slowly beat in the sugar. Add salt, vanilla, and buttermilk and beat to until slightly stiff. You can adjust the consistency by adding more buttermilk, if you prefer a softer icing. This is a base icing adjustable to having ingredients added for your own flavors.
