Chocolate Stout Cupcakes with Irish Cream Buttercream

Adapted from Smitten Kitchen
Makes 22-24 cupcakes

Ingredients:

Cupcakes:
1 Cup Stout Beer
1 Cup Unsalted Butter
¾ Cup Quality Unsweetened Cocoa Powder
2 Cups All Purpose Flour
2 Cups Granulated Sugar
1½  Teaspoons Baking Soda
¾ Teaspoon Salt
2 Large Eggs
⅔ Cup Sour Cream

Ganache Filling
8 ounces bittersweet chocolate
2/3 cup heavy cream
2 tablespoons butter, room temperature
1 to 2 teaspoons Irish whiskey (optional)

Irish Cream Buttercream:
4 to 5 Cups Confections Sugar
2 Cups Unsalted butter, room temperature
4 to 5 Tablespoons Irish Cream Liqueur

Preheat oven to 350°F. Line cupcake cups with paper liners.

Make the cupcakes: Preheat oven to 350°F. Line 24 cupcake cups with liners. Bring 1 cup stout and 1 cup butter to simmer in heavy large saucepan over medium heat. Add cocoa powder and whisk until mixture is smooth. Cool slightly.

Whisk flour, sugar, baking soda, and 3/4 teaspoon salt in large bowl to blend. Using electric mixer, beat eggs and sour cream in another large bowl to blend. Add stout-chocolate mixture to egg mixture and beat just to combine. Add flour mixture and beat briefly on slow speed. Using rubber spatula, fold batter until completely combined. Divide batter among cupcake liners, filling them 2/3 to 3/4 of the way. Bake cake until tester inserted into center comes out clean, rotating them once front to back if your oven bakes unevenly, about 17 minutes. Cool cupcakes on a rack completely.

Make the filling: 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 stir until smooth. (If this has not sufficiently melted the chocolate, you can return it to a double-boiler to gently melt what remains. 20 seconds in the microwave, watching carefully, will also work.) Add the butter and whiskey (if you’re using it) and stir until combined.

Fill the cupcakes: Let the ganache cool until thick but still soft enough to be piped (the fridge will speed this along but you must stir it every 10 minutes). Meanwhile, using your 1-inch round cookie cutter or an apple corer, cut the centers out of the cooled cupcakes. You want to go most of the way down the cupcake but not cut through the bottom — aim for 2/3 of the way. A slim spoon or grapefruit knife will help you get the center out. Those are your “tasters”. Put the ganache into a piping bag with a wide tip and fill the holes in each cupcake to the top.

Make the frosting: Whip the butter in the bowl of an electric mixer, or with a hand mixer, for several minutes. You want to get it very light and fluffy. Slowly add the powdered sugar and the Irish Cream a few tablespoons at a time.

Ice and decorate the cupcakes. Enjoy!

Note: This makes a lot of buttercream so that you can pipe large mounds on the cupcakes. If you prefer less on your cuppies, halve the amounts.
