Autumn is definitely here and I don’t have to tell you that the days are getting shorter and the warm weather is no longer. One of my kids even said the “f” word this morning….frost. It’s time for warmer drinks and comfort foods and I can’t think of anything better than a hot cup of coffee with a Bailey’s shot- or two- in it! I can think of something better actually…how about a Rich Dark Chocolate Mocha Cupcake with the most amazing Bailey’s Swiss Meringue Buttercream?
When I made these, I also filled them with a chocolate ganache infused with Bailey’s. I would leave it out. It’s not necessary because the real star of the dessert here is the icing. You know about my ongoing love affair with Swiss Meringue Buttercream. I have to say that the boozy version is absolute bliss and sits right at the top of my favourites list!
I frosted these this morning before going to work. And you can be darn sure I licked the bowl shiny clean. I could’ve easily eaten the whole bowl without the cupcakes. It’s that yummy. And I had a container of chocolate covered espresso beans for garnish. So as I was licking the icing bowl I was also munching on espresso beans. Breakfast of champions.
You can imagine the state I was in when I got to work….
I couldn’t wait to post this recipe today to share with you! Let me know if the Bailey’s Swiss Meringue Buttercream makes your top ten! Enjoy!
Dark Chocolate Mocha Cupcakes
*adapted from What The Fruitcake?
Makes 24 cupcakes
3/4 cup strong hot coffee
3 tsp instant espresso powder
3/4 cup dark cocoa
3/4 cup unsalted butter, room temperature
2 cups brown sugar
3 large eggs, room temperature
2 1/2 cups flour
1 cup buttermilk, room temperature
1 tsp baking soda
1 tsp baking powder
1 tsp kosher salt
1 tsp vanilla extract
2 tbsp mayonnaise, room temperature
Preheat oven to 350°. Line cupcake pans with 24 cupcake liners
1. Whisk together coffee, espresso powder and cocoa in a small bowl and set aside. Sift together flour, baking soda and baking powder in another small bowl and set aside. Measure out buttermilk and mix with vanilla extract and set aside.
2. In a large bowl cream together butter, sugar and salt. Add eggs, one at a time, beating each egg in thoroughly and scraping the side of the bowl before adding the next egg. Add 1/3 of the flour mixture to the egg mixture and mix until combined. Add 1/2 of the buttermilk and mix until combined. Repeat, ending with the last of the flour mixture. Add the cocoa and coffee mixture and mix until thoroughly combined. Fold in mayonnaise.
3. Divide equally into prepared cupcake liners. Bake for 16-18 mins or until a toothpick inserted comes out clean. Allow to cool thoroughly on wire racks before frosting.
Bailey’s Swiss Meringue Buttercream
- 5 egg whites
- 1 cup + 2 tbsp sugar
- 2 cups of unsalted butter at room temperature
- 1 tsp pure vanilla
- pinch of salt
- Bailey’s to taste
1. Fill a saucepan (large enough to fit your mixing bowl just a few inches) with two inches of water. Bring the water to a boil, then reduce heat to med-low so water continues to simmer.
2. In your stand mixer bowl, hand whisk the egg whites and the sugar just until combined. Place over simmering pot and whisk for approx 4 mins until the egg whites are hot (about 150 degrees). The sugar should be dissolved by this time as well. Place bowl on stand mixer and attach the whisk attachment. Whisk on medium speed until whites have increased in volume, are thick and glossy and the outside of the bowl is just slightly warm to the touch (this can take up to 10 minutes!).
3. Remove whisk attachment and replace with paddle attachment. Beat on low-speed until mixture is completely cooled. Increase speed to medium and add butter pieces one at a time. Scrape the bowl and continue to beat until buttercream is glossy, smooth and thick. It may separate at first, but continue beating and it will emulsify. Add vanilla flavouring, a pinch of salt and Bailey’s (to taste) and beat until combined. Use immediately.
Garnish with a chocolate covered espresso bean.







Oh my, oh my, oh my! These look fantastic. Guess what I’m making this weekend?
These are very pretty cupcakes. Love the espresso bean garnish. Your recipe stating *Bailey’s to taste* leaves it wide open for us doesn’t it? LOL
These look divine!
Savory Simple- divine is the perfect word to describe these lovely cupcakes!
Paula- You are right my friend, add as much as you would like!
Movita- let me know what you think of the icing!
This will be a great holiday dessert for special guests, can’t wait to make them!
Wow. I can’t wait to make these. I’ll make them next week and return to tell you how it went. You’re piping is lovely by the way. Great job! What tip did you use? One more thing… nice photography! All around excellent job!
Lisa, I used a Wilton 1M tip for these.
Renee
Lisa, I would love to hear how they turn out!
Renee
Wow, that is one gorgeous cupcake and reading through the recipe I am seriously drooling!
Yum. These cupcakes sound sooo good! I love the flavor combo. I also love that you do your buttercream the old school way!
Omg these look amazing! Where is the recipie from?!
These look fantastic.
These cupcakes tasted AMAZING! The icing with the hint of Bailey’s was so yummy. These are on my top 10 list of favourites from Sweet Revelations.
Hi Renee! I’ve read thru the instructions a few times and maybe I’m just missing it… but at what point to you use the 2 Tbsp of Mayonnaise?
This looks amazing!
Ooops! Fold the mayo in to your batter as your very last step. Thanks for pointing that out, all corrected now
Renee
Hi Renee, is it at all possible to do this recipe without a mixer? Thanks!
I would also love to make half Bailey’s cupcakes and half purely white vanilla cupcakes using this awesome recipe, is there a way I can alter it for this? Thank you very much!
Kristy- I honestly don’t know if it would be possible to make a Swiss Meringue without a mixer, unless you have some serious muscles! The meringue alone can take up to 10 minutes of beating before it is cooled and glossy enough to add butter. I just don’t think you would get the same results by hand. Please get back to me though if you do give it a whirl, I would love to hear about it!
For the half Bailey’s half vanilla icing- that is fairly easy! Once you make your batch of Swiss Meringue, divide it in half, about 2 1/2 cups per half. Add Bailey’s to taste to one half (still add some vanilla first) and then add vanilla and some vanilla bean seeds to the other half.
Looks like an amazging recipe. I see you used the Wilton 1M tip but can you tell me the technique you used for frosting? ie. angle of your tip and did you do it in two layers? They look fabulous!
Thanks Jo-Ann- I basically hold the piping bag directly above the cupcake, straight in front of me, and apply slight pressure to the bag with one hand while moving it in a circular motion around the cupcake. I do not do it in layers but continue to swirl around the cupcake working my way to the center/top. Release pressure just before your last little swirl on top.
Are all your temperatures in Farenheit? I get that 350 can’t be celcius but for the buttercream part 150 is quite ambiguous, please let us know so I can get making this buttercream!
Julie- it is 150 Farenheit. Let me know how you like it!

Thank you for this recipe! I made mini versions for my St.Patty’s Day cocktail party and they were a HUGE hit!
I assume the mayo is for oil? I don’t use it so don’t have it on hand. Could another oil be substituted? Or shortening?
Pamela- you can leave the mayo out all together. I always add some mayo to my cake batter as it adds some extra moistness.
Renee
what could i use instead of bailys
You could use, caramel for flavour, chocolate, hazelnut, endless possibilities!
so if i wanted to use carmel or cinomion i could just use as much as it calls for the bailys ? lol
I would just add it to taste Ashley
Hi….just wondering how you store youe completed cupcakes after icing them…the frosting was so soft the last time i made them…i put them in fridge to harden…they were good but not sure if they are supposed to be cold….thanx
Hi Adriane- you can put them in the fridge just bring them back to room temperature before you eat them. I generally don’t put my Swiss Meringue cupcakes in the fridge.
These look just lovely and bailey’s swiss meringue sounds incredible! Can’t wait to try them!
I made these cupcakes today. The cupcakes were delicious and looked beautiful but everyone thought the frosting was about a 2 or 3 on a scale of 10.. I made it EXACTLY according to the recipe, It wasn’t very sweet and tasted like eating butter. Will definitely make the cupcakes again but with a different frosting.
Hi Sue,
Thats too bad that you didn’t like the taste- that happens sometimes! Thats why I added Bailey’s “to taste” so that you could put as much in as you wanted to achieve the best Bailey’s flavour. These would also be good with caramel or vanilla or chocolate SMBC.
There is also an oil from LorrAnn Oils that is Irish Cream Flavour. That might be worth a try!
I too, had the same experience with the buttercream, a very strong buttery taste. I did add vanilla and peppermint extract flavoring. But reading all of the reviews makes me want to try it again. Is it supposed to have a very strong butter taste/flavor to it? Or did I possibly do something wrong? Should I try less butter maybe?
HI Tanya,
I’m not sure why you had such a strong buttery taste, especially with the peppermint extract. Did you only add two cups? Strange…please do try again! If you are trying for the mint buttercream, you shouldn’t have such a strong butter flavour. I’m puzzled!
I was just wondering how long the frosting will last. considering you said use immediately. I’m making this for my mom’s birthday sunday but want to make the cakes a day in advance. Is that okay??
Yes that’s ok. The frosting lasts about a week in the fridge and for a few months in the freezer.
Renee
hi. i’m still a student in the Philippines and also a food lover haha. i just want to know what is the purpose of the mayonnaise in the cupcake?? i jreally don’t like mayonnaise ..
You don’t need to use mayo, just omit it from the recipe!
These. Are. Amazing. I made a few changes… First, I made them in a mini version because I was making them for my friends dessert tasting party and everything had to be bite sized. Second, I couldn’t find espresso powder for the life of me so I added some strong instant coffee instead. Once baked, they didn’t taste coffee enough for my liking so for the frosting I used vanilla extract with also some coffee extract. Most delicious dessert I have ever made!!!!! I took home the prize of best overall dessert at the Party! Thanks a million.
At the top of the recipe it states Makes 24, I only made half a recipe, So does that mean it made 12 or the the recipe would make 48? Thanks
Tambi- Thanks for pointing that out! Looking back I have no idea why that is there because the recipe and the frosting yield enough for 24 cupcakes! I removed my comment.
Let me know how they turn out!
Hi I tried this recipe last night the Bailey’s frosting was fabulous. Unfortunately, the cupcake was dry. I did not use the mayonnaise so that may be the reason. Any thoughts?
Hi Tricia- the mayo is not necessary at all. Perhaps they needed less time in the oven? Hard to say what happened, but maybe try taking them out a few minutes earlier? Chocolate can be just very slightly under cooked (few wet crumbs on cake tester). Vanilla however, cannot. If you try them again let me know!
Renee
for the peppermint ones? should we omit both the coffee and the espresso?? or leave the coffee in?
Hi Amy- Coffee definitely stays in, espresso is out. The coffee only enhances the chocolate flavour.
Renee
How do you take out the espresso if it’s already mixed in with the coffee and cocoa?
Hi Christy- if you don’t want a mocha flavoured cake, don’t mix in the espresso. Just use coffee and cocoa. That only enhances the chocolate flavour.
Hello,
I would really like to know what is the point of using mayonnaise in this recipe.
Can it be omitted?
What substitute can be used?
Malak- it just adds some extra moistness to the cake. You can omit it completely if you wish!
