Boozy pumpkin spice buttercream is a delicious fall take on homemade icing. A basic buttercream gets the special treatment with a shot of Bailey's Pumpkin Spice Irish Creme liquor for a frosting you'll want to use on everything this fall.
Using a hand mixer or a stand mixer with the paddle attachment, beat the room temperature butter until it is light and fluffy, about two minutes. Add the powdered sugar, Irish Creme, and heavy cream. Beat until the mixture comes together and gets light and fluffy, scraping down sides to make sure everything gets thoroughly incorporated.
