Why This Recipe Works

• Moist chocolate cupcakes infused with Baileys Irish cream.

• Can be made ahead and stored in the fridge or freezer.
• Perfect balance of sweet chocolate and creamy Irish cream flavor.

Ingredients

Cupcakes:

• 2 cups all-purpose flour

• 2 cups sugar

• 1 cup dark chocolate cocoa powder

• 2 teaspoons baking powder

• 1 teaspoon baking soda

• 1 teaspoon espresso powder

• 1 teaspoon salt

• 2 large eggs, room temperature

• 1/2 cup vegetable oil

• 1 teaspoon vanilla extract

• 1 cup Baileys Irish Cream

• 1 cup boiling water

Baileys Buttercream Frosting:

• 1 cup unsalted butter, softened

• 5 cups powdered sugar, sifted

• 1 teaspoon vanilla extract

• 2–3 tablespoons Baileys Irish Cream

• 1/4 teaspoon salt

Ingredient Tips

• Use high-quality cocoa powder for the richest chocolate cupcakes with Baileys.
• Don’t skip the sour cream .. it keeps these Baileys Irish cream chocolate cupcakes moist and tender.
• Let the butter for frosting come to room temperature for smoother, creamier Baileys chocolate cupcakes frosting.
• Adjust Baileys in the frosting for a stronger or milder Irish cream flavor.

Step-by-Step Instructions

• Preheat the oven and prep your pan: Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners. This ensures your Baileys Irish cream chocolate cupcakes bake evenly and come out perfectly shaped.

• Mix dry ingredients: In a large bowl, whisk together 2 cups all-purpose flour, 2 cups sugar, 1 cup dark chocolate cocoa powder, 2 teaspoons baking powder, 1 teaspoon baking soda, 1 teaspoon espresso powder, and 1 teaspoon salt. Sifting the cocoa helps remove lumps and keeps your batter silky smooth.

• Add wet ingredients: Stir in 2 large room-temperature eggs, 1/2 cup vegetable oil, 1 teaspoon vanilla extract, and 1 cup Baileys Irish Cream. Beat with an electric mixer until fully combined and silky.

• Incorporate boiling water: Slowly add 1 cup boiling water (microwaving for about 2 minutes works fine) and mix well. Your batter will be very thin — that’s exactly what makes these cupcakes moist and tender.

• Portion into liners: Use a large spoon or small measuring cup to fill each paper liner just over halfway with batter. This ensures even baking and prevents overflow.

• Bake: Bake in your preheated oven for 20 minutes, or until a toothpick inserted into the center comes out clean. The tops should be slightly springy and perfectly chocolatey.

• Cool: Remove the cupcakes from the oven and transfer them from the pan to a wire rack. Let them cool completely before frosting. No one likes melty frosting disasters!

• Make Baileys buttercream frosting: In a large mixing bowl, beat 1 cup softened butter until creamy. Gradually add 5 cups sifted powdered sugar, 1/4 teaspoon salt, 1 teaspoon vanilla extract, and 2–3 tablespoons Baileys Irish Cream. Beat until smooth and fluffy, adjusting Baileys to your taste.

• Frost cupcakes: Frost cooled cupcakes with a spatula, or pipe frosting using a large piping bag or a zip-top bag with the corner snipped and a decorating tip. Add chocolate shavings, green sprinkles, or other festive touches for St. Patrick’s Day.

• Serve and store: Serve immediately for ultimate indulgence. Store leftovers in an airtight container in the fridge for up to 3 days.

Texture Control

Cupcakes should be moist and tender with a slightly springy top. Frosting should be creamy and hold its shape but still soft enough to spread easily. Overmixing the batter can make them dense, so fold gently.

Troubleshooting

• Dry cupcakes: Check oven temperature; don’t overbake. Adding a little extra sour cream keeps them moist.
• Runny frosting: Beat longer or chill slightly to firm it up.
• Cupcakes collapse: Avoid opening the oven door too early.

Tips No One Tells You

• I love the rich flavor of using dark chocolate cocoa powder but if you only have regular cocoa powder on hand, don’t make that extra trip to the store.  Both flavors make amazing chocolate cupcakes.
• Sift that powdered sugar before adding it to your butter for your buttercream frosting.  I know I say it every time.. trust your friend Heather!!! … sift the powdered sugar or you will end up with lumps of sugar in your frosting and no one wants that!
• Don’t have a large piping bag to make pretty whoop-whoop cupcakes?  Grab a large zip top bag, snip a bit off the bottom corner, add a decorating tip and then fill that bad boy up with your frosting.  I find if I push my bag into a tall tumbler glass, I can fill it a lot easier with a lot less mess. Keep in mind that big fancy frosting jobs take a ton of frosting to accomplish.. double that frosting recipe if you are getting fancy.
• Bring your eggs to room temperature before using them. Room temp eggs emulsify better and are fluffier than eggs right out of the refrigerator.
• You want to make sure you are measuring your flour correctly. If you scoop out a measuring cup of flour directly from the bag, you will pack in way too much flour. To avoid this, spoon the flour into the measuring cup until its overfilled and then use the back of a butter knife to level the measuring cup at the top. Now you have the perfect flour measurement!
• Don’t over-mix your chocolate cupcake batter. Once run your mixer long enough to incorporate the ingredients to avoid tough or dense cupcakes.
• Use a small measuring cup to add your batter to your cupcake tins. This way your cupcakes are all the same size and save on (most) of the mess.
• Buy milk while you are at the store. Chocolate cupcakes needs to be eaten with a big glass of milk. Buy milk.

Variations That Actually Work

• Swap Baileys for another Irish cream liqueur for a different twist.
• Add chocolate chips to the batter for an extra decadent treat.
• Top with chocolate ganache instead of buttercream for a richer adult dessert.
• Mix green food coloring into frosting for a festive St Patrick’s Day look.
• Add a sprinkle of cocoa powder or edible gold glitter for party-ready cupcakes.
• Turn into mini cupcakes for bite-sized adult-friendly treats.
• Use coffee-flavored Baileys frosting for mocha-chocolate lovers.
• Add a splash of whiskey to frosting for an extra boozy kick.
• Decorate with shamrock sprinkles to make them kid-friendly while keeping the Baileys flavor for adults.
• Make a layered Irish cream chocolate cake using the same batter and frosting for bigger celebrations.

FAQ Section

Can I make these cupcakes ahead of time?
