Ingredients

Scale
For the Guinness Chocolate Cake:
  • 1 cup Guinness stout beer
  • ½ cup unsalted butter
  • ¾ cup unsweetened cocoa powder
  • 2 cups granulated sugar
  • ½ cup sour cream (or Greek yogurt)
  • 2 large eggs
  • 1 tablespoon vanilla extract
  • 2 cups all-purpose flour
  • 2 teaspoons baking soda
  • ½ teaspoon salt
For the Irish Buttercream:

 

  • 1 cup unsalted butter, softened
  • 3 cups powdered sugar
  • 3 tablespoons Irish cream liqueur (like Baileys)
  • 1 teaspoon vanilla extract
  • Pinch of salt

Instructions

Make the Cake:
  1. Preheat & Prep: Preheat oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper.
  2. Heat Guinness & Butter: In a saucepan, heat Guinness and butter over medium heat until butter melts. Remove from heat and whisk in cocoa powder and sugar until smooth. Let cool slightly.
  3. Mix Wet Ingredients: In a large bowl, whisk together sour cream, eggs, and vanilla. Stir in the cooled Guinness mixture.
  4. Combine Dry & Wet: In a separate bowl, whisk together flour, baking soda, and salt. Gradually add to the wet ingredients, stirring until smooth.
  5. Bake: Divide the batter between the prepared cake pans and bake for 30–35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
  6. Cool: Let cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Make the Irish Buttercream:
  1. Beat Butter: In a large bowl, beat softened butter until creamy.
  2. Add Sugar & Flavoring: Gradually mix in powdered sugar, then add Irish cream liqueur, vanilla extract, and salt. Beat until smooth and fluffy.
Assemble & Serve:

  1. Frost the Cake: Spread a layer of buttercream over one cake, place the second cake on top, and frost the entire cake.
  2. Decorate (Optional): Sprinkle with chocolate shavings or drizzle with melted chocolate.
  3. Slice & Enjoy!

Notes

  • No Irish Cream? Substitute with heavy cream + ½ teaspoon espresso powder for a rich flavor.
  • Extra Guinness Flavor: Add 1–2 tablespoons of reduced Guinness to the buttercream.

 

  • Storage: Keep in an airtight container at room temperature for 1 day, or refrigerate for up to 5 days.
