I had a cupcake while in Napa at Sift that was a Guinness Stout with Bailey's frosting and HAD to try to make one myself. While searching the internet, I found cupcakes with not only these ingredients but also with a Jamison whiskey ganache filling. How could I resist my Irish roots calling to me to create this liquor filled cupcake...the results were wonderful!!! The Guinness in the cupcake gives it quite an interesting and delightful taste - and then you get the surprise of the ganache in the center. The frosting with the flavor of Bailey's was just the right amount of sweetness to not overtake the cupcake. All-in-all, me sainted mother would be pleased!
