This cupcake includes all the essential elements of an Irish Car Bomb – a Guinness batter, Jameson ganache, and Bailey’s frosting. Super delicious!
1 cup Guinness
1 cup unsalted butter
3/4 cup cocoa powder
2 cups all-purpose flour
1 1/2 tsp baking soda
3/4 tsp salt
2/3 cup sour cream
Dry ingredients first – whisk together the flour, sugar, baking soda, and salt
Beat together the eggs and sour cream at medium speed until combined. Add the Guinness mixture and beat until combined. Add in the flour mixture, beat on low briefly. Use a spatula to fold the batter until completely combined.
Yield: 24 cupcakes
Finely chop the chocolate and put it in a bowl. Heat the heavy cream until simmering, pour it over the chocolate, and let it sit for one minute. Stir until smooth. Add Jameson and butter, and let it cool until it firms up a bit but isn’t too stiff to pipe.
Whip butter on medium-high for 3-5 minutes. Gradually add in powdered sugar, beating on medium-low until all of it is mixed in. Mix in the Bailey’s, add heavy cream as needed for a smoother and creamier texture to the frosting. Mix on medium-high another 2-3 minutes.
Pipe onto cupcakes and enjoy!
