These mint flavored cupcakes are topped with a malted vanilla frosting. It is your favorite Shamrock Shake in the form of a cupcake! Plus they are spiked with a bit of Baileys Irish Cream.

Every time I remember I have a bottle of Bailey’s Irish Cream in my cabinet, something wonderful happens. This time it is Boozy Shamrock Shake Cakes. These festive green cupcakes are mint flavored cupcakes with a bit of Bailey’s in the batter. And, it wouldn’t be a milkshake without a little vanilla, so they are topped with a vanilla malt frosting, which is also infused with Baileys.

When I used to live in my Vermont, my boss had a few key drinks that he looked forward too. If it wasn’t an eggnog latte, it was a shamrock shake. We would take afternoon drives to the nearest McDonalds, which was 15-20 minutes away, just to get a shamrock shake.

I must admit, it has been a while since I had some myself, but I happen to LOVE the soft serve ice cream from McDonalds and I sure do love mint. Sometimes I feel ashamed to say how much I like their soft serve, but I have been known to stop at the drive thru for a child sized cone.

For these cupcakes, I used a boxed cake mix, which I altered to add some extra vanilla and mint flavor. I used food coloring to turn these cupcakes green and flavored them with mint extract. They smelled SO good.

I wanted to bring more of the milkshake aspect into these cupcakes so I topped them with a vanilla malt frosting and I whipped the heck out of it. This is key in order to achieve a super fluffy frosting. You use your whisk attachment on the mixer and whip the butter first, and then add the powdered sugar and heavy cream. Once they’re mixed, beat it again, a lot! The malt powder adds a bit of the milkshake effect and I add that into the frosting when I add the powdered sugar.

The Baileys in this recipe is optional in both the cupcake and in the frosting. If you do not want to use Baileys in the cupcake, substitute it for milk instead. For the frosting, you add additional milk or heavy cream instead of the Baileys. I just love the flavor that the Baileys adds, especially to the frosting!

Boozy Shamrock Shake Cakes

  • Author: Julianne Bayer
  • Cook Time: 16 mins
  • Total Time: 16 mins
  • Yield: 20-24 cupcakes


  • 1 box Vanilla cake mix
  • 1 box Vanilla pudding (3.4 oz)
  • 4 Large egg whites
  • ½ C Vegetable oil
  • ½ C Milk
  • ¼ C Baileys Irish Cream
  • ½ C Sour cream
  • 3 tsp Pure vanilla extract
  • 1 tsp Mint extract
  • Green food coloring (optional)
  • For the frosting
  • 1 C (2 sticks) Unsalted butter
  • ¼ C Malt powder
  • 1 tsp Vanilla extract
  • 56 C Powdered sugar
  • 1 tbsp Heavy whipping cream
  • 2 tbsp Baileys Irish cream


  1. Preheat oven to 350°F. Line a cupcake pan with paper liners.
  2. In a mixing bowl, combine vanilla cake mix, pudding mix, egg whites, oil, milk, Baileys and sour cream. Beat on medium speed until well combines. Add vanilla and mint extract. Mix until combined.
  3. Use a large cookie scoop (3 tbsp) to fill liners 2/3 C full.
  4. Bake at 350°F for 15-18 minutes. Insert a toothpick into the center of the cupcake. If the toothpick comes out clean, the cupcake is done.
  5. Allow to cool completely.
  6. For the frosting
  7. Butter should be at room temperature or slightly firmer, not melted. Beat on medium speed with your whisk attachment and beat until butter is light and fluffy.
  8. Add malt powder and beat until incorporated. Adding the vanilla extract at this stage will allow the mix to be smoother before adding the powdered sugar.
  9. Add powered sugar one cup at a time, beating on medium-low speed. The frosting will become quite thick. Add heavy whipping cream and increase speed to medium high. Beat for a couple minutes. This will help the frosting to be smoother and creamier. Add remaining powdered sugar.
  10. Once the powdered sugar is mixed, add the Baileys and increase speed to medium-high. Beat for 1-2 minutes on medium-high to incorporate air into the frosting.
  11. Frost cooled cupcakes.

    These cupcakes are so fun and festive! I love that you added Bailey’s and malt to the frosting! They sound amazing!

  4. Carla

    Love Shamrock Shakes, so I’m pretty excited that you turned it into a boozy cupcake! Better wash one of these down with a milkshake 😉

  5. Danae @ Recipe Runner

    Well since you admitted to love McDonald’s soft serve ice cream, I guess it’s same for me to admit my love for it too! I also am totally in love with these cupcakes! I love using Bailey’s whenever possible this time of year and am tickled that you added malt to this delicious frosting! 🙂

  6. Alice @ Hip Foodie Mom

    I’ve realized that I don’t bake enough boozy desserts!! I love these Julianne!!! and we LOVE the soft serve ice cream from McDonalds!! plus, it’s so affordable! If my husband has the choice of that or overpriced ice cream from coldstone (although I do love me some coldstone too), we always go to McD’s. 😛

  7. Stephanie

    Yes, wonderful things come from a bottle of Irish Cream. Love that these are boozey with it!
    I could eat the frosting by itself with a spoon.

  8. D Dell

    Yum!!!!! ~ ya know? Thinking back, every time “I” remember I have Bailey’s, something really great happens as well! These look so good.

    You “sham”rock!

  9. Hayley @ The Domestic Rebel

    How perfect do these look?! Methinks I need to make a batch while drinking my own spiked Shamrock Shake… you know, for the experience.

  10. Ashley | Spoonful of Flavor

    Cupcakes are perfectly acceptable for breakfast right? Baileys in the cupcake and the frosting sounds like a great idea.

  11. Mir

    Um, just awesome. Using malt powder is pretty much the coolest decision ever. And Bailey’s? Pretty much always a good idea.
    Love those cupcake wrappers, too. It’s such a cute presentation!
