  • 1/2 cup unsalted butter
  • 1 cup brown sugar packed
  • 1/4 cup milk
  • 2 cup sifted confectioners' sugar


  • In a saucepan, melt butter.
  • Add the brown sugar.
  • Bring to a boil, lower heat to medium low, and continue to boil for 2 minutes, stirring constantly.
  • Add the milk and return to a boil, stirring constantly.
  • Remove from heat and cool to lukewarm.
  • Gradually add sifted confectioners' sugar. (I would highly recommend sifting this confectioners' sugar. It's such a pain to sift, but it ensures that the frosting will be extra smooth.)
  • Beat until thick enough to spread. If too thick, add a little hot water.
