Irish stout is a well-known and beloved beverage, especially on March 17. And the dark, malty brew is no stranger to the baking world; its rich, roasted flavor makes it an excellent addition to many kitchen creations. Because Irish stout already has aromas of familiar dark roasted things, like coffee and chocolate, it pairs very well with many sweet treats.
This week, celebrate St. Patrick’s Day by baking with beer. Try making these rich and boozy Irish stout cupcakes topped with a fresh and sweet whipped mint frosting.
Irish Stout Chocolate Cake with Whipped Mint White Chocolate Ganache
Yield: Makes 24 cupcakes
For the Mint White Chocolate Ganache:
16 oz white chocolate, chopped into small pieces
1 1/2 cups heavy cream
1/2 cup fresh mint, stemmed and chopped
Pinch of salt
For the Chocolate Stout Cake:
1 3/4 cups flour
1 cup unsweetened cocoa powder
1 teaspoon baking soda
1/4 teaspoon salt
1 1/4 cups Irish stout beer
1/4 cup brewed coffee
1/2 tsp vanilla extract
1 cup (2 sticks) unsalted butter, softened
1 cup packed brown sugar
1/2 cup white sugar
3 eggs, room temperature
The ganache will need time to chill before it can be whipped and applied to the cupcakes as frosting, so to save time, it’s best to prepare it first.
This recipe will make about 4 cups of whipped frosting.
Prepare the ganache:
Place the chopped white chocolate in a large heat-safe bowl; set aside. Combine the heavy cream and chopped mint in a medium saucepan. Bring just to a boil, then remove from heat; cover and let the mint leaves steep for 5 minutes.
While the ganache is chilling, prepare the cake:
Preheat oven to 350 degrees. Line two 12-cup muffin tins with paper liners. Sift together flour, cocoa powder, baking soda, and salt into a large bowl; set aside. Combine the stout, coffee, and vanilla extract in a large bowl; set aside.
Place butter and both sugars in the bowl of an electric mixer; beat on medium speed, until fully combined, about 1 minute. Add the eggs and continue beating to incorporate. With the mixer on low speed, gradually add 1/3 of the flour mixture, followed by 1/2 of the stout mixture. Repeat, ending with the flour mixture. Scrape bottom and sides of the bowl to incorporate any excess flour or cocoa. Continue mixing until batter is smooth.
Prepare the frosting:
Transfer the chilled ganache to the bowl of an electric mixer fitted with the whisk attachment. Whip on high speed until soft peaks form, about 1 to 2 minutes (whip time will vary based on mixer type –– be careful not to overwhip the ganache, as it will turn grainy and start to separate).
Transfer the whipped ganache to a piping bag fitted with a medium-size star pastry tip and pipe on each cupcake. Garnish with sprinkles.
Store cupcakes in airtight container until ready to serve.
