Gourmet Desserts Shouldn't Be Complicated
These are Not Your Kids Cupcakes
Baileys® and espresso cupcakes look like they belong in a bakery’s window display and taste like cocktail hour heaven. What makes these cupcakes stand out is the flavors of fresh coffee, espresso powder, and Baileys added directly to the icing. It’s like biting into an espresso martini! The coffee in this recipe comes from one of my favorite local coffee shops, Brothers Cortado.

Brothers Cortado is the Star of Baileys and Espresso Cupcakes
If you live near Concord, New Hampshire, and haven’t checked out Brothers Cortado, you’re missing out! They’re located off Main Street behind Margaritas at 3 Bicentennial Square. If that address is bringing a bell, the building formerly housed True Brew. If you loved it then, you’ll be even happier now! Brothers Cortado opened in 2021 and brought coffee to the next level. Their menu has a fantastic lineup of coffees, teas, and pastries that will have you hooked. Two of my favorite drinks are the Orange Clove Latte and London Fog. The Orange Clove is perfectly balanced and neither too sweet nor spicy. And if you love Earl Grey tea, try the London Fog! If you’re unsure what to try first, the baristas are amazing and will give recommendations based on the drinks you like. If you work remotely or are a student, you will love the amount of seating (and the number of wall outlets they added during the renovation.)

The Flavors Inside Baileys and Espresso Cupcakes
- The star flavor of this recipe is freshly brewed coffee and espresso powder. The brewed coffee I use in my recipe is Brothers Cortado’s Eclipse blend. I also use Brothers Cortado’s Espresso powder in the batter and as a garnish on top of the icing. Their Eclipse blend is a dark roast bold blend and pairs well with the sweetness of the icing.
- Baileys® is the other star flavor of this recipe. It creates an icing that is creamy, sweet, and slightly boozy. It also balances well with the bitterness of the coffee and espresso.
- Dark chocolate chips balance with the sweetness of the icing and adds additional flavor layers.
- Vanilla extract balances the bitterness of the coffee, espresso, and dark chocolate while adding a touch of sweetness.
- Sour cream provides acidity that reacts with the baking powder to create a rise in the cupcakes and a light and silky texture.

- In a medium bowl or the bowl attachment of a stand mixer, add the granulated sugar and ¾ cup of unsalted butter. Set aside.
- While the butter comes to room temperature, separate four egg whites into a small bowl and set aside. You can discard the yolks or store them refrigerated in an air-tight container for use in other recipes.
- Sift the flour, salt, baking powder, and espresso powder into a medium bowl. Set aside.
- Preheat an oven to 325 °F
- Once the liquid ingredients and butter have come to room temperature, whisk the butter and eggs on medium-low speed until light and fluffy.
- Add half the egg whites to the butter and sugar, mixing on low speed until evenly mixed. Add the remaining eggs and vanilla extract, and mix to combine.
- Add a third of the flour mixture to the butter, and mix on low speed for about 5 seconds.
- Add a third of the coffee mixture to the butter, and mix on low speed for about 5 seconds.
- Alternate adding the flour and coffee mixtures until fully encorporated.
- Add the chocolate chips, and mix just until evenly mixed. Be careful not to over-mix.
- Transfer the batter to a piping bag and fill each muffin mold abou 2/3 of the way.
- Bake the cupcakes at 325 °Ffor 18 to 22 minutes, or until an inserted toothpick removes clean.
- Once baked, allow the cupcakes to cool in the pan before removing.
Baileys Icing
- Add ¾ of room temperature unsalted butter to a stand mixer and beat until light and airy.
- Sift the powdered sugar into the bowl, and whisk to combine. Set aside.
- Combine three tablespoons of modified cornstarch in a small saucepan with three tablespoons of Baileys. Whisk to combine.
- Warm the cornstarch and Baileys over low heat for about three minutes.
- Pour the warmed Baileys and cornstarch into the stand mixer and add the remaining Baileys.
- Blend the icing until evenly mixed. Transfer the icing to a piping bag with a decorative star tip inserted.
- Once the cupcakes have fully cooled, pipe the icing onto the cupcakes.
- For added decoration, you can sift espresso powder over the top of each cupcake. You can also add a whole espresso bean or two and piece of dark chocolate.
