Happy St. Patrick’s Day! Today I’m wearing green and celebrating with these spiked shamrock cupcakes! Given our Irish heritage, my family has always celebrated St. Patrick’s Day. When we lived in Chicago, we’d go to the parade and watch as the City dyed the river green. A lot of the large celebrations around the country have been cancelled this year, but these fun cupcakes are a great way to celebrate at home! While they’re some of my favorite cupcakes, they are definitely for adults as they contain alcohol. These chocolate Guinness cupcakes are filled with a chocolate-Baileys ganache and topped with Baileys frosting, shamrock sprinkles, and a chocolate Mickey!

Chocolate cupcakes with shamrock sprinkles and chocolate mickeys on platter

For my cupcakes, I used these Shamrock cupcake liners that I found at Michael’s. I loved the bright green color and was happy to discover that they keep their color after being baked and didn’t show any grease spots.

To start, prep your muffin pan and preheat the oven. Combine the dry ingredients (except the cocoa) in a bowl and set aside. In a medium saucepan, heat the butter and the Guinness until the butter has melted. Then add the cocoa powder and whisk until smooth. Take the mixture off the heat and let cool slightly while you beat the egg and sour cream together in a large bowl. Once they’re combined, mix in the butter mixture and then the flour mixture. Divide among the prepared muffin pan filling about 2/3 – 3/4 full. Bake for 15-17 minutes. Let cool in the pan for 5 minutes before transferring to a wire rack to cool completely.

While the cupcakes are cooling, make the chocolate Mickeys and the Baileys ganache. To make the make the Mickeys, melt 1/4 cup of cocoa candy melts in a disposable piping bag. I used Wilton light cocoa candy melts and these disposable piping bags. You can also melt the candy melts in a microwave safe bowl and then transfer to a piping bag, but it’s easier to melt them in the piping bag since you’ll need to use one later.

Pipe the melted chocolate onto a parchment or wax paper covered baking sheet in the shape of Mickey heads. Transfer to the refrigerator to set completely while you make the ganache.

To make the ganache, place the chocolate pieces into a heat-safe bowl. Heat the heavy cream in a saucepan until it’s just about to boil. Pour the cream over the chocolate pieces and let sit for a minute. Stir gently until smooth. Add the butter and Baileys and stir until combined. Transfer to a piping bag and set aside until ready to fill.

The last bit of prep work before decorating is making the frosting. To make the frosting, beat the butter until fluffy. Add the powdered sugar and beat until combined. Add the Bailey’s and beat on medium high until fluffy. Transfer to a large piping bag fitted with a large star tip. I used a Wilton 1M tip.

Now, you’ll want to cut a hole in the center of the cupcakes so that you can fill them with ganache. An easy way to do this is to use an apple corer.

Once all of the cupcakes have holes, pipe the ganache into the centers. Then, pipe a swirl of frosting on top of each cupcake. To decorate them, I added a some large gold sprinkles and these adorable shamrock sprinkles from Wilton. Add a chocolate Mickey and your spiked shamrock cupcakes are complete!

Happy St. Patrick’s Day! Enjoy!
