A lot of the times, I hear people are intimidated by making their own cupcakes. I mean it’s easier to just buy from the bakery down the street right? But I also believe that cupcakes are one treat, you definitely can make at home. Especially when they use my go to one bowl chocolate cupcake recipe and an easy 2-ingredient chocolate frosting. 

This time I decided to switch up my chocolate cupcakes and give them a little kick.  And stuff them with an Oreo cookie.

I wanted a recipe that used Mint Oreos or one that used Bailey’s Irish Cream…and well I just couldn’t decide.

That’s when it hit me..duh Heather…use both in ONE recipe.

So that’s when I came up with these Bailey’s cupcakes stuffed with a Mint Oreo.

OH. EM. GEE.

How To Make These Baileys Cupcakes

These Bailey’s cupcakes are my variation of the easy chocolate cupcakes from the perfectly chocolate cake from Hershey’s Kitchens. You could stick to the original recipe, but I love my little twist on them- adding espresso powder. Adding espresso, or strongly brewed coffee to anything chocolate brings out the flavor of the chocolate. 

I decided to add Bailey’s Irish Cream to the batter. I swapped out the milk in the recipe and used Bailey’s instead. The Bailey’s made this cupcake rich and super moist while also giving it a kick of Bailey’s.

In a large bowl you need to combine the dry ingredients (flour, sugar, baking powder, cocoa powder, baking soda, and salt) and simply whisk to combine.

In the same bowl you then add your wet ingredients- bailey’s irish cream, vegetable oil, vanilla, and eggs. And whisk, whisk, whisk again. Then you need to add in your boiling water. I add in the espresso powder to the boiling water before adding to the cupcake batter.

Be careful at this point, when stirring in the hot espresso water. The batter will be thin. But that’s exactly what you want! That thin batter makes for a super moist chocolate cupcake!

 This is a very liquid cupcake batter, so to scoop I recommend placing your batter in a liquid measuring cup to pour them evenly and with little mess.

You want to fill these no more than 3/4 of the way full so they don’t spill over the edges of your pan and create a mess when baking.

Tips For Making These Baileys Cupcakes

  • Get Your Pans Ready First. Before you start be sure to pre-heat your oven and prepare your pans with your cupcake liners.  If your oven is not pre-heated properly, your cupcakes could bake unevenly.  My Favorite Go To Cupcake Liners Are These. 
  • Measure Correctly. Be sure to measure your flour accurately. You want to first give it a stir then spoon it into your dry measuring cup and level off with a flat edge. Overmeasuring your flour can result in dense tough cupcakes. 
  • Use Natural Cocoa. Be sure to use natural unsweetened cocoa powder not dutch process. They are not the same and will affect how the cupcakes turn out!
  • Rotate Your Pans. For cupcakes that all come out perfectly, I like to set my timer for half the time the recipe calls for in order to remember to rotate my pans halfway through baking. Most ovens have what are called “hot spots” where it’s hotter in certain areas. So cupcakes that are in the “hot spots” can bake faster than others, so by rotating your pans halfway through you can ensure they evenly bake.  
  • Use A Cooling Rack. Once baked, it’s best to immediately take them out of the pan and let them cool on a cooling rack. If you leave them in the pan, they will continue to bake from “carryover heat”, which means your cupcakes could come out perfect and then end up being being dry if left in the pan. 
  • Let The Cupcakes Cool. Whatever you do, don’t decorate too quickly or you will melt the buttercream. Make sure your cupcakes are completely cooled before you frost.

How To Make The Bailey’s Ganache Frosting

Now let’s talk about this frosting. This frosting recipe starts by making a ganache.  This is a traditional ganache ratio of 1:1 chocolate to cream. Except this time I’m substituting some Irish cream!

 Then I decided to take my Whipped Ganache Frosting recipe and add some Bailey’s Irish Cream to it. And I’m so glad I did. 

Now it’s time to go ahead and pipe the frosting onto your cupcakes. My favorite tip to achieve that perfect swirl is this one, and I love using these plastic disposable bags. If you haven’t invested in a piping tips and a bags yet, I highly recommend it. It will take your cupcakes from looking homemade to bakery worthy.

Now you can top each cupcake with another Oreo, or a half Oreo, or what I liked the best- some Mint Oreo crumbs.

The Mint and Bailey’s flavors work beautiful together. Can you believe I actually doubted the flavor combination before making these? What was I thinking?

    Do you think it would be ok to replace the Oreo with a Girl Scout thin mint cookie? Not sure if I’m brave enough to try it.

    1. Hi Donna, I think that’s a great idea!! Let me know if you try and how it turns out!

  2. Mary Neeser says:

    Hi, I am not seeing any mention of the Oreos in your recipe. I’m guessing that they are in the cupcake liners, before the cake batter goes in….is that correct? Thank you for your clarification.

    1. Well that’s embarrassing! Haha yes you are correct I place an Oreo cookie in the bottom of the cupcake liner the. Batter over the top. I’ll make sure to update the recipe and thank you for letting me know!

      1. Thank you. Can’t wait to make these cupcakes☘

      2. Let me know how you like them 🙂

    1. Heather @Boston Girl Bakes says:

      Thanks Dorothy!! I have a feeling it won’t be the last mint and oreo combination 😉

  3. These cupcakes are gorgeous Heather! I’ve been meaning to make Bailey’s cupcakes for such a long time but would never have thought to add mint Oreos! Ingenius! I will be making these very soon. Though I hope you don’t mind if I blame you for any weight I gain as a result..

    1. Heather @Boston Girl Bakes says:

      Erika you absolutely can blame away 🙂 if we were neighbors we would go for a run and then snack on these after- because that’s perfectly acceptable right? 😉

  4. You did not just put a mint Oreo in a Bailey’s chocolate cupcake?!?!?! My prayers have been answered! LOL! And chocolate ganache is my favorite frosting so this might be my favorite cupcake recipe of all time. I live just north of Boston and a couple of years ago, after moving here from Florida, I decided I needed to experience St Patrick’s Day in Boston. It was lots of fun but absolutely crazy and needless to say, I have spent the next 2 St Patty’s Days at home. heeehee 🙂

    1. Heather @Boston Girl Bakes says:

      Hi Karrie! Yes …yes I did..and I don’t regret it for a second..I’m telling you the Mint Oreo and Bailey’s needs to be combined more often! And the chocolate ganache frosting I can never get over how simple it is to make and how it’s always the best chocolate frosting I’ve ever had. So pretty much….these were crazy delicious! I’ve done the parade a couple times too and I’m with you absolute chaos! 🙂 So glad you found my blog! Happy Friday!
