for the Cupcake Batter

  • 1 box devil's food cake mix
  • 1 cup Guinness Extra Stout beer

for the Chocolate Whiskey Filling

  • 1 tub chocolate frosting 16 oz
  • 2 tsps Jameson Irish Whiskey

for the Bailey's Buttercream Frosting

  • 1 tub butter cream frosting 16 oz
  • 2 tbsps Bailey's Irish Cream


mix & bake the Cupcakes

  • Prepare the cake batter following the instructions on the back of the box replacing the water for the Guinness beer. I use either Duncan Hines Devil's Food or Pillsbury Devil's Food cake mix. Both call for 1 cup of water which I substitute with 1 cup of Guinness.
  • Fill a cupcake pan with the batter and cook according to the instructions on the box.
  • Take the cupcakes out of the oven and allow to cool for 10 minutes.
  • While the cupcakes are cooling, prepare the cupcake filling and frosting.

prepare the Cupcake Filling & Frosting

  • For the cupcake filling, add the chocolate frosting (I use Duncan Hines Dark Chocolate Fudge) and Jameson Irish Whiskey to a mixing bowl and mix with a hand mixer on low to medium speed until the whiskey is fully incorporated into the frosting.
  • For the frosting, add the buttercream frosting (I used Betty Crocker Butter Cream) and Bailey's Irish Cream to a mixing bowl and mix with a hand mixer on low to medium speed until the Bailey's is fully incorporated into the frosting.

make them Car Bomb Cupcakes

  • Now, core the cupcakes by inserting a knife about halfway in from the top of the cupcake and cut out a circle. Then, using the knife or a small spoon, scoop out the middle of the cupcake about halfway down into the cupcake. I use a cupcake corer to make this task easier. Now fill the cupcake with the whiskey infused chocolate frosting.
  • Next, add the buttercream frosting to a piping bag and decorate the top of the cupcake with the Bailey's buttercream.
  • Serve and enjoy these wonderfully easy Irish Car Bomb Cupcakes.
