These Baileys and coffee cupcakes are adapted from my vanilla cupcakes and are made with Baileys, strong black coffee, and a touch of espresso powder. Review notes before beginning.


  • 1 and 3/4 cups (207gcake flour* (spooned & leveled)
  • 2 teaspoons espresso powder*
  • 3/4 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup (113gunsalted butter, softened to room temperature
  • 1 cup (200ggranulated sugar
  • 3 large egg whites, at room temperature*
  • 1 and 1/2 teaspoons pure vanilla extract
  • 1/3 cup (80gsour cream or plain yogurt, at room temperature
  • 1/4 cup (60ml) strong black coffee, cooled to room temperature*
  • 1/3 cup (80ml) Baileys Irish Cream*

Baileys Coffee Buttercream

  • 1 cup (226g) unsalted butter, softened to room temperature
  • 4 cups (480g) confectioners’ sugar
  • 1/2 teaspoon espresso powder (optional)
  • 3 Tablespoons (45ml) Baileys Irish Cream
  • 1 and 1/2 Tablespoons strong black coffee, cooled to room temperature
  • pinch of salt
  • optional for garnish: chocolate sprinkles


  1. Preheat the oven to 350°F (177°C). Line a 12-cup muffin pan with cupcake liners. Line a second pan with 2 liners—this recipe makes about 14 cupcakes. Set aside.
  2. For the cupcakes: Whisk the cake flour, espresso powder, baking powder, baking soda, and salt together. Set aside.
  3. Using a handheld or stand mixer fitted with a paddle attachment, beat the butter on high speed until smooth and creamy, about 1 minute. Add the sugar and beat on high speed for 2 minutes until creamed together. Scrape down the sides and up the bottom of the bowl with a rubber spatula as needed. Add the egg whites and vanilla extract. Beat on medium-high speed until combined, then beat in the sour cream. Scrape down the sides and up the bottom of the bowl as needed. With the mixer on low speed, add the dry ingredients until just incorporated. With the mixer still running on low, slowly pour in the coffee then the Baileys. Beat just until combined. Do not over-mix. You may need to whisk it all by hand to make sure there are no lumps in the bottom of the bowl.
  4. Pour/spoon the batter into the liners—fill only 2/3 full to avoid spilling over the sides. Bake for 19-22 minutes, or until a toothpick inserted in the center comes out clean. For around 30-36 mini cupcakes, bake for about 11-13 minutes, same oven temperature. Allow the cupcakes to cool completely before frosting.
  5. Make the frosting: With a handheld or stand mixer fitted with a paddle or whisk attachment, beat the butter on medium speed until creamy, about 2 minutes. Add confectioners’ sugar, espresso powder (if using), Baileys, and coffee. Beat on low speed for 30 seconds, then increase to medium-high speed and beat for 2 full minutes. Add up to 1/2 cup more confectioners’ sugar if frosting is too thin or another Tablespoon of Baileys if frosting is too thick. Add a pinch of salt if frosting is too sweet. (I add and recommend 1/8 teaspoon salt.)
  6. Frost cooled cupcakes and top with sprinkles, if desired. I used Ateco 808 piping tip. Cover and store leftover cupcakes in the refrigerator for up to 5 days.


  1. Make Ahead & Freezing Instructions: Cupcakes can be made ahead 1 day in advance, covered, and stored at room temperature or in the refrigerator. Frosting can also be made 1 day in advance, covered, and stored in the refrigerator. Bring to room temperature before using. If frosting is too thick, beat in 1 Tablespoon of Baileys or room temperature black coffee to thin out. Frosted or unfrosted cupcakes can be frozen up to 2-3 months. Thaw overnight in the refrigerator.

  3. Cake Flour: Real cake flour is ideal in this recipe. However, in a pinch and if you can’t get cake flour, use this homemade cake flour substitute. I suggest doing this twice, mixing it all up in 1 bowl then removing 1/4 cup since you need 1 and 3/4 cups in this recipe.
  4. Espresso Powder & Coffee: I use both espresso powder and strong black coffee in the cupcake batter and buttercream. For the cupcake batter, you can add the espresso powder with the dry ingredients like I do (it dissolves just fine in the batter) or stir into the black coffee before pouring in. What would also work is just using 1/4 cup room temperature brewed espresso instead of both coffee AND espresso powder. The espresso powder is optional in the frosting, but I recommend it for more flavor. And in the frosting, you could also use 1 and 1/2 Tablespoons room temperature espresso instead of the coffee AND espresso powder.
  5. What to Do with Leftover Egg Yolks? Here are all of my recipes using only or extra egg yolks.
  6. Baileys: You can use regular Baileys or any flavors that this Irish cream comes in. I know there’s salted caramel and espresso flavors that would be great here!
  7. Alcohol Free: You can skip the alcohol completely for plain coffee cupcakes and coffee buttercream. To do so, replace the Baileys in the cupcake batter and buttercream with strong black coffee– 7 Tbsp of coffee total in the cupcakes and 4-5 Tbsp in the buttercream.
  8. Cake: This recipe would be a delicious cake. Use this batter and frosting and follow my 6 inch cake recipe instructions. For a 9 inch layer cake, I recommend using my white cake recipe. Reduce sugar down to 1 and 1/2 cups (300g). Add 1 Tablespoon espresso powder with the dry ingredients. Instead of 1 cup of milk, use 1/2 cup (120ml) Baileys, 1/4 cup (60ml) strong room temperature coffee, and 1/4 cup (60ml) whole milk. This amount of frosting should be plenty for the cake.
