Ingredients

Scale
  • 1 cup Guinness stout (240 ml)
  • 8 tablespoons unsalted butter, cut into cubes and softened (113 g)
  • 3/4 cup unsweetened cocoa powder (75 g), Dutch-processed
  • 2 cups granulated sugar (400 g)
  • 3/4 cup sour cream, room temperature (180 ml)
  • 2 large eggs, room temperature
  • 2 cups all-purpose flour (240 g)
  • 2 1/2 teaspoons baking soda
  • 1/4 teaspoon salt
  • 1 teaspoon peppermint extract
  • 1/2 cup mint chocolate chips (90 g)
  • 8 ounces cream cheese, softened (225 g)
  • 1/2 cup unsalted butter, softened (113 g)
  • 3 cups powdered sugar (360 g), sifted
  • 1/4 cup Bailey’s Irish Cream (60 ml)
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C). Grease two 9-inch cake pans and line bottoms with parchment paper.
  2. In a medium saucepan over low heat, melt butter into Guinness. Remove from heat and whisk in cocoa powder until smooth.
  3. Sift together flour, baking soda, salt, and sugar in a large bowl.
  4. In another bowl, whisk sour cream, eggs, and peppermint extract until smooth.
  5. Pour Guinness-cocoa mixture into wet ingredients and stir gently.
  6. Fold wet mixture into dry ingredients using a rubber spatula until just combined.
  7. Fold in mint chocolate chips carefully.
  8. Divide batter evenly between pans and bake 40-45 minutes until a toothpick comes out clean or with moist crumbs.
  9. Cool cakes in pans for 15 minutes, then invert onto cooling racks and cool completely (at least 1 hour).
  10. Beat cream cheese and butter until fluffy using an electric mixer.
  11. Gradually add powdered sugar on low speed, then add Bailey’s and vanilla extract and beat until smooth and creamy.
  12. Place one cake layer on serving plate, spread frosting generously, add second layer, and frost top and sides evenly.
  13. Optionally, sprinkle mint chocolate chips or shaved dark chocolate on top.

Notes

Use low heat when melting butter into Guinness to avoid bitterness. Sift dry ingredients for smooth batter. Avoid overmixing to keep cake tender. Chill frosting if too soft or add milk/Bailey’s if too stiff. Cake flavors deepen after resting overnight. Store covered in refrigerator up to 4 days or freeze unfrosted layers up to 3 months.
