Chocolate Stout Cupcakes with Baileys Ganache and Jameson Frosting


Editors note:  Thank you to everyone who is coming by for my cupcake recipe this year. Just a quick note, you’ll see that I’ve changed the title.  I’ve always been conflicted about naming it after the drink or just spelling out what the cupcake is.  I’m proud of my work and I think you’ll love this cupcake but I feel better about not offending anyone with the name.  

Today I have your one stop, one shop St. Patrick’s Day party needs covered.  Not only am I providing you with a cupcake filled with three types of liquor but I have 13 other amazing recipes to share too! 

First, the most important point, these cupcakes are 21 and over ONLY.  

Second, raise your hand if you’ve dared to actually drink an Irish Car Bomb.  Yes? Well you are a brave soul.  Oh, me?  You want to know?  Well, umm. . . I can’t remember, I think I might have in college, or perhaps I remember being with someone when they ordered it, but truthfully it’s been tucked so far in the archives it isn’t coming back up!

Irish Car Bomb Cupcakes

I love baking with beer, especially stouts, as I feel they really compliment chocolate, but I wanted to do something fun and a little different this time around.  Technically though, I shouldn’t even call these an Irish Car Bomb because things are out of order. 

The drink is done as follows: your trusty bartender fills up a pint with Guinness, and then pours a shot of Jameson and a shot of Bailey’s.  Then you pour the Jameson into your Guinness and quickly drop the Bailey’s in before it curdles.  Drink quickly. 

Irish Car Bomb Cupcakes

Don’t be upset: I can’t stand Bailey’s.  An unfortunate incident has caused me to never tolerate it again.  The idea of a Bailey’s buttercream was not sounding good.  So I switched it around.  Bailey’s ganche, and Jameson buttercream.  Hide the Bailey’s yo.  

Extra special thanks needs to go out to Jen at Jen’s Favorite Cookies today.  She is the mastermind behind this amazing collage and arranged all you see below.  Go and say hi and check out everyone else’s recipes too which are listed at the bottom.

Kerrygold was awesome enough to send me a St. Patrick's party in a box, included was Clodagh's Kitchen Diaries by Clodagh McKenna. My cupcake recipe is based very slightly off her Chocolate Birthday Cake on page 118.

Save Recipe


  • For the cupcakes:
  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 cup cocoa powder
  • 1 1/2 sticks butter, room temperature
  • 1 1/4 cups white granulated sugar
  • 4 large eggs
  • 12 ounce Guinness stout
  • 1 teaspoon vanilla extract
  • For the Bailey's ganache:
  • 1/2 cup semi-sweet chocolate chips
  • 1/4 cup heavy cream
  • 3 tablespoons Bailey's
  • For the Jameson Buttercream
  • 1 cup unsalted butter, room temperature
  • 4 cups confectioners sugar
  • 1/4 cup Jameson Irish Whiskey


    For the cupcakes:
  1. Pre-heat your oven to 350 degrees F. Line two cupcakes tins with cupcake wrappers.
  2. In a medium bowl, whisk together the flour, baking powder, baking soda, salt and cocoa powder. Set aside.
  3. Using your stand mixer or hand mixer, cream together the butter and sugar until light and airy. Beat in the eggs one at a time until well combined. Mix in the vanilla extract.
  4. Starting and ending with the flour mixture, alternating between the Guinness mix in parts, making sure not to over mix the batter.
  5. Scrape down the sides and bottoms of the mixing bowl, scoop into the prepared tins and bake for 25 minutes or until a toothpick inserted comes out clean.
  6. Let cool completely before frosting.
  7. For the ganache:
  8. Heat the heavy cream in a small pot on medium heat until it begins to just simmer. Remove from the heat and stir in the chocolate until completely melted.
  9. Whisk in the Bailey's and set aside to cool.
  10. For the buttercream:
  11. Using your stand or hand mixer, beat the butter and confectioners sugar until light and creamy, about 2-3 minutes.
  12. Pour in the Jameson and beat for an additional minute, until well combined.
  13. If you choose to do so, scoop the buttercream into a prepared piping bag to frost the cupcakes.
  14. Assembly:
  15. With a small paring knife, remove a small section of the center of each cupcake. Pour in 1/2 teaspoon of the Bailey's ganache into each hole and place the cupcakes into the refrigerator for 20 minutes to set up.
  16. Once the ganache is slightly firm, top each cupcake with the Jameson Buttercream.

    I’ve never had an Irish Car Bomb drink. It sounds like a humdinger for sure. I’m not sure I could handle it BUT I’m positive I could handle these cupcakes. Great recipe for St. Pat’s!

    yum! I LOVE baileys so I made the icing with it and did the jameson filling. I could never do these in college..what can I say, I am not a chugger haha.

    1. Erin

      When you made it with the Jameson filling and the Bailey’s frosting, did you use the same amounts called for in this recipe? So 3 tbsp of Jameson and 1/4 cup of Bailey’s?

        Hi Erin!

        Yes that’s correct, the buttercream packs quite the punch, so you are always welcome to reduce the amount of whiskey if you so desire. Enjoy! Susan

    I’m pretty sure I’ve had an Irish car bomb. I say pretty sure because it involves downing a ridiculous amount of alcohol in a short span of time, which tends to impair memory somewhat. 🙂 (Also, I wouldn’t touch such a concoction unless I’d already had a few drinks, which might also contribute to this memory problem of mine.)
    This sounds like a much tastier way to get the beer/whisky/Bailey’s trifecta in my belleh. Love the idea of a Jameson’s buttercream. Yum!

  10. Nancy @ gottagetbaked

    I strongly suspect than an overindulgence in the Baileys produced your aversion to it and same with the convenient amnesia over your Irish car bomb days 😉 I love these cupcakes – way to get three types of booze in there, Susan! I’m totally on board.

    1. Susan

      Oh yeah, let’s just say it would not be a good story if I wrote about the last night I drank Baileys. It didn’t end well. I also never suggest it as a gift to a 21 year old, as it sat in my kitchen and I, uh, pre gamed that fateful night with it. uggggh.

    Um, seriously these are the bomb. Bah, couldn’t help myself. These are gorgeous Susan. I would inhale a dozen all by my lonesome. Perfect St Patty’s Day dessert.

  13. Stefanie @ Sarcastic Cooking

    I can say I am one of the brave souls who have dared to try and chug this massive shot/drink. The thought of drinking something quickly before it curdles before your eyes is rather nasty to think about after you have already attempted to drink this. The taste of the two together is rather nice though and I know this has to translate into a sturdy yet fluffy cupcake. I was just looking for something to make to celebrate that isn’t dyed and this will be perfect! Pinned!

  14. Jenn and Seth

    now i’m starting to feel all weird about the fact that i’ve never had an irish car bomb…how did i miss trying this drink?? so to make up for this, i think i totally need to make these to celebrate st pattys this year

  15. Carla

    You don’t like Baileys?! Then again I had a bad incident with that shot called Pineapple Upside Down Cake, so I totally get never drinking it again. Love that you used ganache for the filling!
