Chocolate Stout Cupcakes with Whiskey Ganache and Irish Cream Frosting

Everyone’s a little bit Irish on St. Patrick’s Day and Chocolate Stout Cupcakes are a sweet ending to your celebration to help you Eat, Drink and Be Irish!

 Guinness Stout enhances the flavor of the chocolate in the same way coffee does, resulting in a richer chocolate flavor.

These cupcakes start with a cake mix and are filled with an Irish Whiskey Ganache and topped with an Irish Cream Buttercream Frosting. I added a little shamrock straw as a festive decoration to the cupcakes to play off the Guinness, Irish Whiskey and Irish Cream in this Irish nip. Despite the all the liquid ingredients, you won’t find these cupcakes overly boozy. . . just a subtle note of Irish Cream in the frosting and chocolate-malt flavor from the Guinness Stout. The Irish whiskey is the most pronounced flavor in the oh-so-decadent chocolate ganache!


Chocolate Stout Cupcakes with Whiskey Ganache and Irish Cream Frosting,  adapted from Betty Crocker

Cupcake Ingredients, Makes 24 Cupcakes

1 box Betty Crocker SuperMoist devil’s food cake mix

1 1/4 cups Guinness Stout beer

1/2 cup vegetable oil

3 eggs

 Preheat oven to 350°F (325°F for dark or nonstick pans). Place a paper baking cup in each of 24 regular-size muffin cups.

In large bowl, beat all cupcake ingredients with electric mixer on low speed 30 seconds. Beat on medium speed 2 minutes, scraping bowl occasionally. Divide batter evenly among the muffin cups using a cookie scoop for easy filling.

Bake 18 to 23 minutes or until toothpick inserted in center comes out clean. Cool 10 minutes; remove cupcakes from pans to cooling racks. Cool completely.

Have your Irish Whiskey and Eat It Too in this decadent ganache. . .


Irish Whiskey Ganache

8 oz. good quality dark chocolate, chopped (I used Ghirardelli, 1 bar of bittersweet chocolate and 1 bar semi-sweet chocolate)

3/4 cup heavy cream

1/4 cup Irish whiskey (I used Jameson)

To Make Ganache filling:

Coarsely chop chocolate bars and place in a heat proof bowl. In a small saucepan, bring cream and Irish whiskey just to a boil over medium-high heat. Pour cream mixture over chocolate and let stand for 1 minute, until chocolate has softened. Whisk the mixture until smooth and chocolate is melted and shiny. Transfer bowl to refrigerator and let stand until just chilled, no longer than 30 minutes and stirring occasionally.

Transfer cooled ganache filling to piping bag fitted with a Wilton 2A tip. Insert tip directly into cupcake, squeezing as you pull the tip up and out of the cupcake to add filling.

Note: I bought a special Bismarck filling tip, also known as a Wilton #230 tip (pictured on the left) but the opening was too narrow to pipe the ganache. While I’m sure it will come in handy for other cupcake fillings, my #2A round piping tip worked best for the ganache.


Irish Cream Buttercream Frosting, Makes about 4 cups


6 cups confectioners’ sugar

2 sticks unsalted butter, softened

4 Tbs. Bailey’s Irish Cream

3 tsp. milk

1/4 tsp. salt

In the bowl of an electric mixer fitted with the flat beater, combine all ingredients and beat on low speed until combined, about 1 minute. Stop mixer and scrape down the sides of the bowl. Increase the speed to medium and beat until fluffy, about 3 minutes.

 If the frosting is dry, add more milk, 1 tsp. at a time, until it is creamy but still holds peaks. Transfer frosting to piping bag and top cupcakes. I used a Wilton 1M piping tip. Add some sprinkles or nonpareils if desired.

    Almost looks too pretty to eat! Notice, I said “almost”, hehe. I’ll let you know how the bread pudding and salted caramel sauce turns out and the spinach tortilla shamrocks with the avocado-humus dip. We are having this with homemade Ruebens! Thanks Mary, Happy St. Paddy’s Day! ☘

      OH my, Mary, what a treat you gave us with these wonderful recipes! The tortilla chips were fun to make, turned out great and were so tasty with the delicious avocado-humus dip. The bread pudding and the salted caramel whiskey sauce is just too wonderful. Family was totally pleased. Hubby had seconds and we have extra sauce for an ice cream treat as well. Both recipes get 5 stars and will be made again for sure. Thank you so much. Blessings to you and your family! ☘

    Happy St. Patrick’s Day, May! The cupcakes look beautiful and I wish I could taste one for my dessert today. I made the Irish Cream yesterday, so that’ll be a yummy treat. I’m actually celebrating with a dinner tomorrow, because I’m having my two-year-old granddaughter over to spend the night tonight. We’ll be partying tomorrow with the rest of her family. Slainte!
