This easy penuche frosting is cooked on the stovetop for just a few minutes. The frosting has a fudgy texture, and it is fabulous on a butter pecan cake or spice cake. 

Spread it on these butternut squash cupcakes or brown sugar cupcakes. If the frosting is too firm, add a little hot water. To smooth the frosting, dip your spatula or knife in hot water as you spread.


  • 1/2 cup (8 tablespoons) unsalted butter

  • 1 cup brown sugar, packed

  • 1/4 cup milk

  • 2 cups sifted confectioners' sugar, more or less

  • Hot water, optional

Steps to Make It

  1. In a saucepan, melt 1/2 cup butter. Add the brown sugar. Bring to a boil and lower heat to medium-low. Boil for 2 minutes, stirring constantly.

  2. Add the milk and bring back to a boil, stirring constantly.

  3. Remove the pan from the heat and let the mixture cool to lukewarm.

  4. Gradually add sifted confectioners' sugar while beating until thick enough to spread. If too thick, add a little hot water.

  5. Makes enough frosting to cover the top and sides of a 2-layer cake or a 13x9-inch cake.
