Irish Car Bomb Cupcakes

The last time I had an Irish Car Bomb was senior year of college. As I recall, I didn’t even really want to drink it. I hate beer, and I stay away from whiskey if I can help it, but my friend Melissa told me that if I chugged the drink really quickly all the ingredients would mix together and taste exactly like a chocolate milkshake. She LIED.

The Car Bomb was nothing like a chocolate milkshake. As I choked down the thick fizzy brew, all I could taste was the bitter yeastiness of Guinness, the burn of cheap whiskey (Canadian Mist), and the faintest hint of sweetness from the generic cream liqueur we bought instead of real Baileys. It. Was. Not. Delicious. I was not happy.

(Blurry. Ugh. I hate shooting in low light.) 

This cupcake version of the Irish Car Bomb does make me happy, however. It makes me very happy. What’s not to love about a moist, tender chocolate cupcake filled with rich chocolate ganache and topped with sweet, boozy buttercream?  Nothing. It’s the best! Not too boozy, not too sweet; just rich and chocolate-y and delicious. If the drink tasted like these cupcakes, I would be drunk all the time.

Happy early St. Paddy’s Day, everyone!

** I know that the name “Irish Car Bomb” is technically sort of offensive, but it’s the name I’ve always known the drink by. Hopefully no one is offended by this dessert — feel free to call them “Boilermaker Cupcakes” or “St. Paddy’s Day Cupcakes”!

      Thank you! They really are delicious…I’ll have to pawn them off on my friends before I eat the whole batch!

    I have no recollection of that incident, Tina 😛 But I do agree about the taste of normal car bombs… my wimpier version (with it’s 3:2 ratio of Guinness to Baileys) is much more enjoyable! I do really enjoy baileys in a steaming mug of coffee, though it lacks the excitement of a car bomb haha. Still, it is a morning drink…

    These cupcakes look wonderful though–even though you called me a liar!! <3 you!

      I was actually going to make the frosting with coffee AND Baileys, but I got lazy and the sun was disappearing…

    Love the story and the recipe is even better! I had never heard of a “car bomb” and after reading your description, I’ll leave those for the young people. I’ll pass thank you! However, you are welcome to pass a few of those cupcakes my way. They look delicious!

    Im not a fan of the traditional Irish car bomb shot. However, after making your Irish car bomb cupcakes, I fell in love! They are soooooo DELICIOUS! Thank you for sharing! That whiskey chocolate center is pure heaven!

      I’m not a fan of the drink either! But there’s something magical about chocolate + booze, isn’t there? I’m so glad you liked the cupcakes :)

    I’m planning on making these for my fiance’s birthday and he loves the irish car bomb shot and it was actually the first shot we had together lol. I was wondering in the ingredients it says cream, what kind of cream did you use? i went to the store and saw heavy whipping cream and was wondering if there was a specific one?

  5. Katie says

    I was wondering when you added the whiskey to the ganache. After it cools? Or while it is still simmering in the sauce pan?

      Good question! Can’t believe I left that out of the directions – sorry about that. Add the whiskey while it’s still on the stove, after your chips have melted. Hope that helps!
