Guinness, Whiskey & Irish Cream Cupcakes
The classic cocktail shot transformed into cupcakes – Guinness chocolate cake, Jameson whiskey ganache filling, and Baileys buttercream frosting.

Please tell me that you’ve had the good fortune of tasting chocolate cake that’s been spiked with Guinness. If you haven’t, stop what you’re doing right now, go buy a six-pack of Guinness, grab some chocolate, and head to the kitchen.
The chocolate flavor is so deep and intense, almost malty, and the cake is just so incredibly moist – you’ll definitely want to start making these Guinness cupcakes all year long!
These cupcakes are the #1 all-time most popular recipe on the site, and for good reason. They are utterly spectacular. They are fashioned after the popular cocktail that consists of a shot of Baileys Irish Cream and Irish whiskey dropped into a pint of Guinness. I have never had one myself, but I’ve heard that if you can get it down before it curdles, it’s smooth, delicious and almost tastes like a milkshake.
I’ve never been into doing shots, so I’ll just eat a cupcake and call it a day. Cupcake trumps shots every day of the week for me!

To replicate the drink, I baked up Guinness chocolate cupcakes, filled them with a Jameson whiskey chocolate ganache, and topped them with a Baileys Irish Cream-spiked version of my favorite vanilla buttercream frosting.

While there are a few steps to these cupcakes, they really are simple to bake and assemble. Once the cupcakes are cool, I cut out the centers (and nibbled on the scraps, shhhh), scooped in ganache, and then topped them with lofty swirls of the Baileys buttercream frosting.
I waited for my ganache to thicken before scooping it into the cupcakes, but I think you could fill them when it’s still pretty soft, as it should then firm up inside of the cupcakes.


While you can’t taste the beer in the cupcakes (it serves as a flavor enhancer for the chocolate), you can definitely taste the alcohol in the filling and the frosting. Everyone that I’ve ever made these for absolutely adores them and can’t get over how fantastic they taste. They are truly the trifecta of boozy Irish cupcakes!
Whether you’re throwing a St. Patrick’s Day party, or just need an excuse for some really amazingly delicious boozy cupcakes, look no further! These are guaranteed to be a hit wherever you take them.

Guinness, Whiskey & Irish Cream Cupcakes
Ingredients
For the Cupcakes:
- 1 cup (230 ml) Guinness stout
- 1 cup (227 g) unsalted butter, at room temperature
- ¾ cup (64.5 g) Dutch-process cocoa powder
- 2 cups (250 g) all-purpose flour
- 2 cups (400 g) granulated sugar
- 1½ teaspoons (1.5 teaspoons) baking soda
- ¾ teaspoons (0.75 teaspoons) salt
- 2 eggs
- ⅔ cup (153.33 ml) sour cream
For the Whiskey Ganache Filling:
- 8 ounces (226.8 g) bittersweet chocolate, finely chopped
- ⅔ cup (158.67 ml) heavy cream
- 2 tablespoons butter, at room temperature
- 2 teaspoons Irish whiskey
For the Baileys Frosting:
- 2 cups (454 g) unsalted butter, at room temperature
- 5 cups (600 g) powdered sugar
- 6 tablespoons Bailey's Irish Cream
Instructions
- Make the Cupcakes: Preheat oven to 350 degrees F. Line two standard muffin tins with liners.
- Place the Guinness and butter in a medium saucepan and bring to a simmer over medium heat. Add the cocoa powder and whisk until the mixture is smooth. Remove from the heat and cool slightly.
- In a medium bowl, whisk together the flour, sugar, baking soda, and salt; set aside.
- Using an electric mixer, beat the eggs and sour cream on medium speed until combined. Add the Guinness-chocolate mixture to the egg mixture and beat just to combine. Reduce the speed to low, add the flour mixture and beat just until it starts to come together, about 30 seconds. Using a rubber spatula, fold the batter until completely combined. Divide the batter among the cupcake liners. Bake until a thin knife inserted into the center comes out clean, about 17 minutes. Cool for 5 minutes in the pan, then remove the cupcakes to a wire rack to cool completely.
- Make the Whiskey Ganache Filling: Place the chocolate in a heatproof bowl. Place the heavy cream in a small saucepan and bring to simmer over medium heat. Immediately pour it over the chocolate, then let it sit for two minutes. Using a rubber spatula, gently stir the mixture from the center outward until smooth. Add the butter and whiskey and stir until combined. Let the ganache cool until thick but still soft enough to be piped, about 30 minutes. (If it becomes too stiff, simply give it a good whisk and it will loosen up.)
- Fill the Cupcakes: Using a paring knife, cut the centers out of the cooled cupcakes, going about two-thirds of the way down. Using a cookie scoop or spoon, divide the prepared ganache between the centers of the cupcakes.
- Make the Baileys Frosting: Using the whisk attachment of a stand mixer, whip the butter on medium-high speed for 5 minutes, scraping the sides of the bowl occasionally. Reduce the speed to medium-low and gradually add the powdered sugar until all of it is incorporated. Add the Baileys, increase the speed to medium-high and whip for another 2 to 3 minutes, until it is light and fluffy.
- Using your favorite decorating tip, or an offset spatula, frost the cupcakes and decorate with sprinkles, if desired. Store the cupcakes in an airtight container at room temperature for up to 4 days.

Oh my! Those look and sound awesome. I’m not a fan of beer, but the few times I had an Irish Car Bomb, I did like it! And I LOVE Bailey’s!
If you haven’t seen it already, you might like the cookbook “Booze Cakes” by Krystina Castella and Terry Lee Stone.
I made these last year and they were delicious. The frosting is amazing!
The cupcakes are FANTASTIC!
OMG- These are insanely ridiculously delicious! We purchased, we created and we CONQUERED! Each cupcake weighs seemingly a pound (it’s the butter) and were the most decadent treats to eat and share. I work at a high school, shared them with my teachers and staff and felt like I was gifting precious little cups of St. Patrick’s Day “forbidden” goodness…fantastic all around!
So you are saying you took alcohol infused treats into a public high school?
You couldn’t get my two year old drunk with one of those cupcakes, I don’t think it’s a huge risk.
AMAZING! I brought them to a St. Patrick’s Party tonight and they were a HUGE HIT! Thanks!
This was wonderful! Family loved them… Thanks so much for the idea!
I made these for work today and everyone loved them! Thanks so much for sharing this great recipe!
Great recipe! I did a post about St. Patty’s Day feasts and linked to this recipe in a shoutout. Thanks for posting it! Here’s my link.

I made these cupcakes last night and they are AMAZING! They disappeared very quickly at work today :)
I linked to these in my blog: http://jaclynscookies.blogspot.com/
Thank you for sharing this fabulous recipe!
I’ve made these a bunch of times from smitten kitchen and they are amazing. The only improvement I’ve found is using a Sweet/Milk Stout. The cupcakes are much more yummy without the dry bitterness of the Guinness. They are a hit every time I make them.
I’m attempting to make these now! Do they need to be refrigerated once they are filled and frosted?
Nope! You can store them at room temperature.
Thank you! They turned out great. I can’t wait to enjoy them tomorrow!
I’ve been wanting to try these for years – so glad to see a recipe for them just in time for St. Patty’s. Quick question – what tip did you use to pipe your frosting (or how)? It looks so pretty and much better than my slapping it on with a spatula!
Hi Michelle, I used a Wilton 1M tip and just sort of swirled it around. Enjoy the cupcakes!
I made these to bring to work tomorrow — both my husband and I almost passed out from how delicious they were. Cannot wait to hear what everyone has to say tomorrow. I did leave out the ganache thinking that ALL the alcohol would make them NSFW. I will make them again for this weekend WITH the ganache :)
How far ahead of the festivities can these be made?
Hi Melissa, You can make them up to a day in advance. After that, they won’t be as fresh.
I made these tonight to take to the office tomorrow. They smell delicious! I can’t wait to see what people think tomorrow. Thanks for the recipe.
I just made these and they are simply DELICIOUS! My roommates ate up half of them before I could even pack them up for work. I did sub greek yogurt for the sour cream (because that’s what I had in the fridge) and they were still amazing. Can’t wait to share them! Thank you for the recipe.
Thank you so much for sharing these! I have wanted to make them for a year now and spotted them on your blog. I made these tonight and they turned out wonderfully! I’m super excited to share these with my friends over some green beer tomorrow…I linked you here http://damegoodeats.blogspot.com/2011/03/irish-car-bomb-cupcakes.html
thanks again! :)
those are beautiful! and look so delicious! i agree that turning drinks into food is a wonderful thing!
Guinness, Bailey’s and Jameson all in one recipe! YUM! And how perfectly iced these little darlin’s are! This is a perfect St. Patty’s recipe! Dessert tomorrow, then…
I made a different version of these last night, sans the filling. I used Young’s Double Chocolate Stout and the recipe for both cake and Irish Cream frosting differ but they were DELICIOUS! The Young’s brings an excellent flavor to the cupcakes. I posted them on my blog this morning because they were that good! Sent the rest with hubby to work though…I’d eat them all! :)
And the fact that these cupcakes are filled makes them that much more fabulous!! So fun :)
I must have these, they sound absolutely AH-mazing….(and the drink is delicious if you can get it down…its been a few years since I could!)
These look and sound delicious!! Love all the green. Can’t wait to make it! Bookmarked and stumbled :)
OH MY….
I made these last year from Smitten Kitchen! But I did a whiskey caramel center to mix it up a bit…
The Bailey’s Frosting is truly lifechanging. Seriously.
These are so wrong, they are right. What a great idea for a St. Patty’s day treat!
I just made this cake last night! How funny to see it on this morning on your blog. I made mine into a single layer cake (with 6 cupcakes left over), and frosted it with the peanut butter frosting recipe from her (which uses the natural stuff, just peanuts and salt!) http://www.epicurious.com/recipes/food/views/Chocolate-Cake-with-Milk-Chocolate-Peanut-Butter-Frosting-and-Peanut-Butter-Brittle-351020
Just in case you’re ever interested in a new’do for the cake! So, so, tasty!
They look so delish! Can’t wait to try!!
Holy hell yes please! I cannot tell you how much I am drooling right now over these! I love Irish Car Bombs and then to put it into a cupcake?! ::drools:: I am bowing down to you my Brown Eyed baker, you are a genius!
Oh, I need to get on this! I made some homemade Bailey’s last night ( and, um *cough* had a couple of shots), which I’m definitely using for these awesome looking cupcakes! Thanks for sharing such a great recipe!
Okay, this is serious business here. I need to get some Guinness pronto!
