A Rich, Thick, Caramel Frosting--Great for Cakes or Cupcakes
Melt butter in saucepan; stir in brown sugar and salt. Bring to a rolling boil and boil rapidly 2 minutes, stirring constantly. Remove from heat, carefully stir in milk, then return to a rolling boil. Cool 20 minutes or until lukewarm. Beat in confectioners' sugar until smooth. Add more liquid if necessary if frosting is too stiff.
Makes enough for a two-layer cake.
