Ingredients

Scale
  • 1 cup (240ml) Guinness stout (room temperature)
  • 3/4 cup (170g) unsalted butter, cut into pieces
  • 2/3 cup (65g) unsweetened cocoa powder (Dutch-processed recommended)
  • 2 cups (400g) granulated sugar
  • 3/4 cup (180ml) sour cream (full-fat)
  • 2 large eggs, room temperature
  • 2 cups (250g) all-purpose flour
  • 2 1/2 teaspoons baking soda
  • 1/2 teaspoon salt
  • 8 oz (225g) cream cheese, softened
  • 1/2 cup (115g) unsalted butter, softened
  • 34 cups (360-480g) powdered sugar, sifted
  • 1 teaspoon pure vanilla extract
  • Pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease well.
  2. In a medium saucepan over medium heat, combine Guinness stout, unsalted butter, and cocoa powder. Stir occasionally until butter melts and mixture is smooth, about 3-4 minutes. Remove from heat and let cool slightly.
  3. In a large bowl, whisk together granulated sugar, sour cream, and eggs until smooth and creamy.
  4. Slowly pour the cooled Guinness-chocolate mixture into the sugar mixture, whisking constantly to incorporate.
  5. In a separate bowl, sift together all-purpose flour, baking soda, and salt. Gradually fold dry ingredients into wet mixture using a spatula until just combined.
  6. Divide batter evenly among cupcake liners, filling each about two-thirds full.
  7. Bake for 18-22 minutes or until a toothpick inserted in the center comes out with a few moist crumbs. Cupcakes should spring back lightly when touched.
  8. Remove cupcakes from oven and place on a cooling rack. Let cool completely before frosting, about 30-40 minutes.
  9. For frosting, beat softened cream cheese and butter together until smooth and creamy, about 3 minutes on medium speed.
  10. Gradually add powdered sugar, starting with 3 cups and adding more if needed for desired thickness. Mix in vanilla extract and a pinch of salt. Beat until fluffy, about 2 minutes.
  11. Spread or pipe cream cheese frosting generously over cooled cupcakes.

Notes

Use room temperature Guinness to prevent butter from seizing. Do not overmix batter to keep cupcakes tender. Let cupcakes cool completely before frosting to avoid melting. For extra fudginess, add 1 tablespoon espresso powder to batter. Frosting can be chilled for 15 minutes if too soft or loosened with a teaspoon of milk if too stiff. Store cupcakes in airtight container in refrigerator up to 4 days; freeze unfrosted cupcakes up to 3 months.
