Brown Sugar Frosting Recipe

Brown sugar frosting is one of my favorite frostings. If you use light brown sugar, as shown above on my sweet potato cupcakes, the brown sugar frosting tastes like a thicker version of the glaze on a glazed doughnut. If you use dark brown sugar, as shown below, the flavor is a bit richer and the frosting is somewhat more creamy. This makes sense since dark brown sugar is really just light brown sugar plus additional molasses.

You can’t go wrong either way.


Replace the powdered sugar with peanut butter for a peanut butter brown sugar frosting!

  • 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.
