Guinness Buttercream Frosting

Pair your chocolate Guiness cupcakes with this beer flavored buttercream icing. At first thought, you might think we're overdoing it with Guinness, but give the recipe a try!

The chocolate cupcakes are denser and more chocolate flavored than anything, with the Guinness giving it a subtle enhancement. Paired with the creamier buttercream frosting, it's the perfect balance of sweet and savory.

  • 1 cup unsalted butter (room temperature)
  • 2 1/2 cups sifted powder sugar
  • 1/4 cup milk
  • 1/2 whole scraped vanilla bean
  • 1/2 tablespoon vanilla extract
  • 1 cup Guinness Extra Stout

In a sauce pan, simmer Guinness on low heat for 10-15 min, until it stout becomes reduced and thicker in consistency. Similar to a syrup. *Tip: keep your eye on the stove, so stout does not over cook. Let cool.

In a stand alone mixer, cream your butter for 1 minute

Slowly add the powder sugar in thirds, alternating with a little milk each time till mixture is creamy.

Add scraped vanilla bean and vanilla extract.

Slowly add reduced Guinness a little at a time. Taste test to desired flavor. You may not use all the Guinness reduction.

Place buttercream in a piping bag with a #848 french star tip, frost cupcakes and enjoy!
