Irish Car Bomb Cupcakes

We went away for St. Patrick's Day weekend with some friends.  It wasn't specifically for the holiday.  We always have a day in the spring that we head to a friends beach house.  Since it was a St. Patrick's Day, I decided that a special dessert was needed.  I had found this recipe on Pinterest and knew it would be a great way to celebrate.

These were a little time consuming with the batter, the ganache, and the frosting, but they were worth it.

Irish Car Bomb Cupcakes
From Brown Eyed Baker

Ingredients:

For the Cupcakes:
1 cup Guinness stout
1 cup unsalted butter, at room temperature
¾ cup cocoa powder
2 cups all-purpose flour
2 cups granulated sugar
1½ teaspoons baking soda
¾ teaspoons salt
2 eggs
2/3 cup sour cream

For the Whiskey Ganache Filling:
8 ounces bittersweet chocolate
2/3 cup heavy cream
2 tablespoons butter, at room temperature
2 teaspoons Irish whiskey

For the Baileys Frosting:
2 cups unsalted butter, at room temperature
5 cups powdered sugar
6 tablespoons Baileys Irish Cream

Instructions:

Cupcakes:
Preheat oven to 350 degrees F.
Line 24 cupcake cups with liners.
Bring the Guinness and butter to a simmer in a heavy, medium saucepan over medium heat. Add the cocoa powder and whisk until the mixture is smooth. Cool slightly.

Whisk the flour, sugar, baking soda and salt in a large bowl to combine. Using an electric mixer, beat the eggs and sour cream on medium speed until combined. Add the Guinness-chocolate mixture to the egg mixture and beat just to combine. Reduce the speed to low, add the flour mixture and beat briefly. Using a rubber spatula, fold the batter until completely combined. Divide the batter among the cupcake liners. Bake until a thin knife inserted into the center comes out clean, about 17 minutes. Cool the cupcakes on a rack.

Whiskey Ganache:
Finely chop the chocolate and transfer it to a heatproof bowl. Heat the cream until simmering and pour it over the chocolate. Let it sit for one minute and then, using a rubber spatula, stir it from the center outward until smooth. Add the butter and whiskey and stir until combined. Let the ganache cool until thick but still soft enough to be piped.

To Fill the Cupcakes:
Using a 1-inch round cookie cutter (or the bottom of a large decorating tip), cut the centers out of the cooled cupcakes, going about two-thirds of the way down. Transfer the ganache to a piping back with a wide tip and fill the holes in each cupcake to the top.

Bailey's Frosting:
Using the whisk attachment of a stand mixer, whip the butter on medium-high speed for 5 minutes, scraping the sides of the bowl occasionally. Reduce the speed to medium-low and gradually add the powdered sugar until all of it is incorporated. Add the Baileys, increase the speed to medium-high and whip for another 2 to 3 minutes, until it is light and fluffy.

Frost using a decorating tip or an off-set spatula.
