Since living in Baton Rouge for college–the amount of time doesn’t matter at this point, y’all, just know it was a while ago–I’ve become a fan of St. Patrick’s Day and all the shenanigans it encompasses.

I realize that’s a strange time to say I fell in love with St. Paddy’s, but I did. I have no Irish blood running through my veins, though my name is derrived from “Eireann,” meaning Ireland. (Or if you dig farther, like I had to do for an etymology course in high school, it means “peace.”)

I never felt such a connection to the holiday as I did in college. And it wasn’t just because of all that green beer. (Or all those Guinness beer floats and milkshakes.)

I attended my first St. Patrick’s Day parade–The Wearin’ of the Green–in Baton Rouge during college. Granted, the years I lived on the parade route, I slept through the parade. However, I enjoyed the festivities, nonetheless.

When we moved back to Baton Rouge after our stint in Nashville, I was overjoyed we could celebrate this gloriously green holiday.

The added bonus was we had various friends who lived on the parade route, all of whom hosted parties. Which meant we spent an entire Saturday bouncing from party to party and offering boozy cupcakes to our cohorts. As you do. 😉

… Words cannot express how much I adore this dessert.

The cupcakes are oh-so-chocolate-y and insanely moist. Like, enough so that I have to mention it here, even though I loathe the worst moist.

The icing is strong, even though it only calls for a tablespoon of Bailey’s Irish Cream, and this dessert is perfect for a crowd. I mean, the combination of Irish Cream and dessert is one of my favorites and has been for a while. (I’m lookin’ at you, too, Chocolate Chip Irish Cream Pound Cake and Irish Cream Biscuits with Boozy Chocolate Ganache.)

How do I make the BEST Chocolate Guinness Cupcakes?

Don’t skip the beer. Trust me on this, y’all. It makes the chocolate so much richer, and the alcohol bakes out, so you don’t need to worry about that!

That said, if you don’t use Guinness, that’s OK, but replace it with another full-bodied stout beer that’s NOT flavored.

How do I make this recipe even more decadent?

Brush the cupcakes with Irish Whiskey before icing.

It’s insanely good, should you be into whiskey.

How do I make this boozy cupcake recipe kid-friendly?

The beer will bake out of the cupcakes as they cook, so you shouldn’t fret about the beer. The purpose of the stout is to give the chocolate some extra punch and to let the cupcakes be insanely moist. 

For the icing, simply add milk or a little half-and-half  instead of Irish Cream.

If you’re hesitant to serve kids these cupcakes, even though the beer cooks out, I suggest whipping up my Sour Cream Funfetti Cupcakes instead. Just be sure to use St. Patrick’s Day-colored sprinkles to add to the festiveness.

How can I successfully make these cupcakes for my party without stressing out?

First and foremost: Take a breath!

Secondly: Plan ahead. Bake the cupcakes the night before and store on the countertop covered.

Make the icing in the morning and ice before the party or let your guests ice their cupcakes and decorate ’em, too!

Looking for the PERFECT boozy dessert to bring to St. Patrick's Day festivities? Chocolate Guinness Cupcakes with Creamy Bailey's Icing make a lovely sweet treat.

Chocolate Guinness Cupcakes

  • 1 cup unbleached all-purpose flour
  • 1 1/2 teaspoons baking soda
  • 1 1/2 teaspoons baking powder
  • 1/4 teaspoons salt
  • 1/4 cup unsweetened cocoa powder
  • 3 eggs
  • 1/2 cup crema di mascarpone cheese, (can substitute cream cheese), at room temperature
  • 1 cup granulated sugar
  • 1 cup Guinness Extra Stout Beer

Creamy Bailey's Icing

  • 1/2 cup crema di mascarpone cheese
  • 1 tablespoon Bailey's Irish Cream
  • 2 cups powdered sugar


  1. Preheat oven to 375°F. Line a cupcake pan with cupcake liners, and set aside.
  2. Get out two mixing bowls for the batter.
  3. In the larger of the two bowls, combine the flour, soda, powder, salt and cocoa. Whisk together until incorporated.
  4. In the smaller bowl, cream together the eggs, mascarpone, and sugar using a hand mixer or a stand mixer.
  5. Add the Guinness to the wet ingredients and stir until combined.
  6. Pour the wet ingredients into the dry ingredients and whisk until just combined.
  7. Pour the batter into cupcake liners.
  8. Bake at 375 for 15 minutes or until a toothpick comes out clean.
  9. While baking the cupcakes, stir and combine all ingredients for the icing using a hand mixer.
  10. When cupcakes have cooled completely, ice.
  11. Enjoy!


Please note that you might have to bake your cupcakes for a bit longer. In my older oven, I had to bake them for 22 minutes for them to be cooked all the way through.

To make this recipe KID FRIENDLY: Substitute milk for Bailey's in the icing. You don't need to worry about the Guinness in the cupcakes, though, because as the cupcakes cook, the alcohol will evaporate and give an extra chocolate-y punch.

To make this recipe EXTRA DECADENT: Brush the cupcakes with Irish Whiskey before icing.

    Uh oh. I think you may have just made my boyfriend a very happy man. I think I may make these for him!

    • Erin

      DO IT! They’re delicious and super tasty. And the icing and simple syrup on top are the perfect things to go with that rich cupcake.

      Let me know what y’all think!

    MMMMMM!! Want to try those cupcakes for sure! Do not have a St. Patrick’s Day recipe unfortunately AND sadly enough this year I’ll be missing out on the annual Greenville Avenue St. Patty’s Day Parade here in Dallas. The parade itself isn’t THAT exciting, but so many people come out for it and then there’s a big block party. It’s just really cool to see some many people in Dallas out together!

    • Erin

      Give them a shot, and let me know what you think of them!

      I’m sad that you’re missing out on the annual parade in Dallas, but hopefully, you’ll be able to make next year’s! And I second the coolness of seeing so many people come out for a parade and partying throughout. I’m a big fan of that, and hope you have fun!

  3. Krysten O.

    Yeah, I’m pretty not happy with you for posting those. Now I’ve got to keep Charles’ eyes off this page for at least a week! 🙂

    • Erin

      You know I posted them for you and Charles, personally. 😉

      Have fun tomorrow! And don’t let him look at this page! I’ll just make some of these for him whenever we come to Houston, and we’ll hide them from you. Heh.

    I made a version of these last year! My brother was born on St. Patrick’s Day and my dad’s side of the family is mostly Irish, so it’s a big day for us. I’m making them again this year for a St. Patty’s party my boyfriend and I are attending. The recipe I used didn’t have the simple syrup and the frosting was butter cream instead of cream cheese… they were delicious!

    • Erin

      I love that you made a version of these cupcakes last year AND that your brother was born on St. Patty’s Day AND that you have a mostly Irish family. That’s awesome!

      Enjoy your cupcakes tomorrow, and I hope y’all have a wonderful time!

    oh these look delicious. i may have to give these a go this weekend, mmmm.

    • Erin

      Do it!

      I hope you have a fabulous St. Patrick’s Day!

    Ok, so I attempted these for the NYE bash that unexpectedly happened at my house, and while everything went swimmingly for the cupcakes and the cream cheese icing, the Jameson syrup proved way too complicated for a novice like me. Therefore, as someone who will never let alcohol go to waste, I injected the watery, sugary whiskey into the cupcakes! (ok, so a little missed and ended up in the cook, a perk I’m sure).
    Let’s just say, the cupcakes were a hit!
    Thanks so much.

    • Erin

      For what it’s worth, the syrup was a bit of a challenge for me the first go round, too, girl. SO glad they were a hit for your NYE Bash, and I hope you continue trying some different recipes here!
