Irish Car Bomb Cupcakes

by Allison @ Alli 'n Son on March 11, 2012

I’m all about cupcakes lately. But they have to be filled. Otherwise it’s just a piece of cake and frosting, where’s the fun in that?

There’s no fun. Zero. Even if the frosting is fantastic, which is necessary for a good cupcake, if it isn’t filled, I’m not eating it.

Wait, no. I’ll still eat it. But I won’t be happy about it.

Now, St. Patty’s Day is this Saturday, March 17th. I’m already celebrating with Homemade Bailey’s Irish Cream, but I need something to go with it. A girl can’t live on Bailey’s Irish Cream along. Or so I’ve been told.

But, since it is St. Patty’s Day, whatever I’m enjoying with my Irish Cream, better have some booze in it. That’s the only way to celebrate, am I right?

Yes, yes, I’m right.

Irish Car Bomb Cupcakes

And so, I present to you my take on Irish Car Bomb Cupcakes (inspired by the Irish Car Bomb drink). Guinness Stout chocolate cupcakes. Filled with chocolate whiskey ganache. All topped with an Irish Cream Cream Cheese frosting.

Irish Car Bomb Cupcakes

Can you taste the decadence? Can you taste booze? Okay, you can’t really taste the booze exactly, but all of the flavors combine and complement each other so perfectly, so beautifully, that these Irish Car Bomb cupcakes practically sing.

They sing a song that you can dance an Irish jig to, obviously. But still, I think that counts as singing.

Yield: 24 cupcakes

Irish Car Bomb Cupcakes

Dark chocolate stout cupcakes, filled with chocolate whiskey ganache and topped with Irish cream cream cheese frosting.


    Guinness Stout Cupcakes
  • 3/4 cup unsweetened Hershey’s special dark cocoa powder
  • 2 cups sugar
  • 2 cups all-purpose flour, sifted
  • 1 teaspoon baking soda
  • Pinch fine sea salt
  • 1-1/2 cups (one 12 oz bottle) Guinness (stout beer), at room temperature
  • 1/2 cup (1 stick) butter, melted and cooled to room temperature
  • 1 tablespoon vanilla extract
  • 3 large eggs, at room temperature
  • 3/4 cup sour cream, at room temperature
  • Whiskey Chocolate Ganache Filling
  • 8 ounces bittersweet chocolate, chopped
  • 2/3 cup heavy cream
  • 2 tablespoons butter, room temperature
  • 1 to 2 teaspoons whiskey
  • Bailey's Irish Cream Frosting
  • 8 ounces cream cheese, at room temperature (ideally left on the counter overnight)
  • 1/2 cup (1 stick) unsalted butter, softened (ideally left on the counter for 2-3 hours)
  • 4 tablespoons Irish Cream
  • Pinch of fine sea salt
  • 2 cups powdered sugar, sifted


    Guinness Stout Cupcakes
  1. Preheat oven to 350 degrees.
  2. Line two 12-cup muffin tins with cupcake liners. Set aside.
  3. In a medium sized bowl whisk together the cocoa powder, sugar, flour, baking soda, and salt. Set aside.
  4. In the bowl of an electric mixer, on low speed, combine the stout, melted butter, and vanilla.
  5. Beat in the eggs, one at a time, until mixed in.
  6. Add the sour cream and mix until smooth (if the butter hardens a little, the batter may not be perfectly smooth, that's okay).
  7. Slowly add in the flour mixture. Mix until combined.
  8. Using an ice cream scoop, fill each lined muffin tin about 3/4 full.
  9. Bake for 24-26 minutes, rotating the pans halfway through.
  10. Cool completely.
  11. To fill the cupcakes, use a small paring knife to cut a cone shape out of each cupcake, about 2/3 of the way down. Using a frosting bag and tip, pipe the ganache into each cupcake.
  12. Frost each cupcake with cream cheese frosting.
  13. Whiskey Chocolate Ganache Filling
  14. Put the chopped chocolate in a heatproof bowl.
  15. In a small pot, heat the cream over medium heat until simmering, stirring occasionally.
  16. Pour cream over chocolate. Let it sit a few minutes to soften the chocolate. Stir until smooth.
  17. Add butter and whiskey. Stir to combine.
  18. Let sit at room temperature until thick enough to spoon or pipe into the cupcakes. To speed up the process, put the ganache in the fridge, stirring often, until thickened.
  19. Bailey's Irish Cream Frosting
  20. In the bowl of an electric mixer with a paddle attachment, beat the cream cheese on medium speed until smooth, about 1 minute.
  21. Scrap down the sides of the bowl, then add the butter. Beat on medium speed until combined, about 1 minute.
  22. Mix in the Irish Cream.
  23. With the mixer on low, slowly add in the salt and powdered sugar. Beat on medium speed until the mixture is smooth, scraping down the sides of the bowl as needed.

how amazingly creative and super delicious! I’m drooling

2 Dorothy @ Crazy for Crust March 12, 2012 at 8:21 pm

Wow! Those are awesome! They really are like an bomb of Irish flavor!

3 Julia {The Roasted Root} March 12, 2012 at 10:44 pm

Hey there! I love your site! It’s creative and colorful. These cupcakes look wonderful…Guinness is actually my favorite beer (shhhh, don’t tell anyone, I get made fun of for that fact) and I love the variety of chocolate and alcohol that you put in the recipe. This looks like quite the chocolatey treat with a kick! Look forward to seeing more of your recipes :)

4 Allison @ Alli 'n Son March 14, 2012 at 9:27 pm

You can’t go wrong with chocolate, right? :

5 JC March 12, 2015 at 9:59 pm

Psh… Guinness is my favorite too and when anyone tries to make fun of me for it, because I’m a girl, I just look them in the eye and chug it.

6 BluBabesCreate March 13, 2012 at 9:55 pm

Love the politically incorrect name! Come check out my politically incorrect breakfast!

7 Marie P March 14, 2012 at 1:03 pm

Using “Irish Car Bomb” to celebrate an Irish holiday – literally, a holy day – is akin to creating a drink called the “falling twin towers” and promoting it on Sept 11.

Seriously, can we have a little more sensitivity? The Irish “Troubles” isn’t a subject that should be made light of in such a way.

8 Allison @ Alli 'n Son March 14, 2012 at 9:30 pm

I meant no offense, these cupcakes were inspired by the drink, not anything political.

9 Marie P March 14, 2012 at 9:40 pm

Honestly, it’s less about the name (The name of the drink is offensive any day, though)… and more about the choice to use *that* name in conjunction with St Patrick’s Day. It’s insult to injury.

I’m sorry.. i know this was posted well over a year ago but i couldn’t help but chime in. I stumbled upon this recipe after realizing that you could mix dessert and beer successfully. I love chocolate, baileys, and stouts.. I couldn’t ask for more! I’m incredibly excited to make these in the near future and if i remember, i’ll let you know how ridiculously amazing they’re sure to turn out. That being said, I am 100% irish. I was born in Cork County but my parents immigrated here when i was a wee baby and the rest of my family (minus and aunt and uncle) still live in Ireland. We would go back about once a year to visit when i was younger and i’m currently bursting with anticipation over my upcoming trip back. I’m proud of my heritage, love being an irish citizen (i love america too, don’t worry), and respect every bit of my countries past.. but i also have a sense of humor, something the Irish are known for. Your choice of name whether based off of the drink (obviously) or the actual event (those would be dangerous cupcakes) is in no way offensive. I find it clever, creative, and very appropriate. I just had to let you know this in case you were made to feel as though you had done something wrong. Don’t let any person or their ignorance get in the way of your talent and self-expression.

11 Green March 14, 2012 at 7:21 pm

Marie, please relax. She did not invent the drink!! There are plenty of cocktails with less than savory names. I think this is a great way to celebrate Irish flavors and they compliment each other very well in this cake, despite the name of the drink.

Thanks for the recipe Allison! I made these yesterday and they were awesome!

12 Allison @ Alli 'n Son March 14, 2012 at 9:30 pm

Thanks Green! I’m glad you enjoyed the cupcakes, despite the name. 😉

13 Bonnie March 14, 2012 at 9:15 pm

Love the recipe…cupcakes look delicious
Gotta do something about the name though….not cool

14 Allison @ Alli 'n Son March 14, 2012 at 9:32 pm

The name of the cupcakes come from the drink they were inspired by, nothing political. I’m sorry if it offended you.

15 Miz Helen March 16, 2012 at 3:45 pm

Oh my goodness Ali, this is a great way to celebrate St. Patrick’s Day. These Cupcakes look amazing! Hope you are having a great week end and thank you so much for sharing with Full Plate Thursday.
Happy St. Patrick’s Day!

These are the bomb! Thanks so much for sharing ~ such great combos. I can only imagine how wonderful they will taste.


17 Lilly March 16, 2012 at 8:14 pm

I am literally making these as I type this. Amazing. Though I recommend not making these alone. One person eating the middles of all these cupcakes… Oof.

The name is not offensive. Don’t change it.

18 Paul Newman August 23, 2012 at 7:13 pm

As a proud and devout Irishman, Alli, I LOVED THESE CUPCAKES!!!!

They BLEW (‘scuse the pun) my taste buds, the combination of stout and chocolate is amazing.

Bye the bye Marie P, I took no offence to the name, or the drink. Love the work Alli, keep it up

19 Charlie February 15, 2013 at 4:01 am

Would the same ingredients work for a 9/11 cupcake, I could bake enough for all the kids in “Tuesday’s Children”.
