Description
These Guinness chocolate cupcakes are rich, moist, and infused with deep cocoa flavor and a subtle malty warmth from reduced Guinness stout. Topped with a whipped chocolate buttercream, they’re a go-to for cold-weather gatherings and indulgent cravings.
Ingredients
1 cup Guinness stout
1 cup unsalted butter, cut into chunks
3/4 cup Dutch-process cocoa powder
2 cups all-purpose flour
2 cups granulated sugar
1 1/2 teaspoons baking soda
3/4 teaspoon salt
2 large eggs
2/3 cup sour cream
1 tablespoon vanilla extract
1 cup unsalted butter, room temperature
3 cups powdered sugar
1/2 cup Dutch-process cocoa powder
2 to 4 tablespoons heavy cream
1/2 teaspoon vanilla extract
Pinch of salt
Instructions
1. In a saucepan, bring Guinness to a simmer over medium heat and reduce by half. Let cool.
2. Preheat oven to 350°F and line cupcake pan with liners.
3. In a large bowl, whisk together flour, sugar, baking soda, and salt.
4. In another bowl, combine melted butter, cocoa, and reduced Guinness. Mix until smooth.
5. Beat in eggs, sour cream, and vanilla, then combine with dry ingredients until batter is smooth.
6. Fill cupcake liners 2/3 full and bake for 17–20 minutes, or until a toothpick comes out with a few moist crumbs.
7. Cool in pan for 5 minutes, then transfer to a rack to cool completely.
8. For frosting, beat butter until light and fluffy (5 minutes).
9. Gradually add powdered sugar and cocoa, alternating with cream, until light and creamy.
10. Add vanilla and salt, whip briefly, and frost cooled cupcakes.
Notes
Let the Guinness reduce gently; boiling too hard can create bitterness.
Use high-quality Dutch-process cocoa for maximum richness.
Make sure cupcakes are fully cool before frosting to prevent sliding.
