How to Make Guinness Chocolate Cake with Irish Buttercream
-
Preheat the oven: Set your oven to 350°F. Prepare two 8-inch wide x 3-inch deep cake pans by greasing them and lining the bottoms with parchment paper rounds. This will ensure easy removal after baking.
-
Mix the dry ingredients: In a large mixing bowl, whisk together the flour, granulated sugar, cocoa powder, baking soda, baking powder, and salt. This combination will create the perfect chocolate base for your cake.
-
Whisk the wet ingredients: In a medium bowl, combine the sour cream, vegetable oil, eggs, vanilla extract, and Guinness beer. Whisk until smooth, ensuring all ingredients are blended nicely together.
-
Combine wet and dry ingredients: Pour the wet ingredients into the dry mixture, stirring gently until just combined. Be careful not to overmix; you want a tender cake crumb, so a few lumps are okay!
-
Bake the cakes: Divide the batter evenly between the prepared pans. Bake for 35 to 40 minutes, or until a cake tester comes out clean. Allow the cakes to cool in their pans for about 30 minutes before transferring them to a cooling rack to cool completely.
-
Prepare the frosting: In a large bowl, beat the unsalted butter until light and fluffy. Gradually add the sifted powdered sugar and Irish cream. Beat on high speed for about 3 minutes until the frosting is light and smooth. Adjust the consistency with more Irish cream or powdered sugar as needed.
-
Assemble the cake: Place one cooled cake layer on a cake stand or serving plate. Generously frost the top with a layer of your fluffy Irish buttercream. Top with the second cake layer, ensuring the flat side is facing up.
-
Crumb coat the cake: Apply a thin layer of frosting all around the cake to catch the crumbs, then refrigerate until the crumb coat is firm to the touch. This step is key for a clean final appearance.
-
Frost generously: Spread the remaining frosting evenly over the entire cake, focusing on the top for a playful ‘naked’ look. Set the cake aside in the refrigerator while you make the chocolate ganache.
-
Make the ganache: Chop the semisweet chocolate and place it in a heatproof bowl. In a small saucepan, bring the heavy cream to a simmer, then pour it over the chocolate. Cover for a few minutes, then stir until smooth and combined.
-
Cool the ganache: Allow the ganache to cool slightly until thickened but still pourable, about 10 minutes. Test the consistency to achieve that perfect drizzle over your cake.
-
Drizzle and decorate: Carefully pour some of the ganache over the top of the chilled cake, allowing it to drip down the sides. Use a squeeze bottle for more artistic drips if desired, then add your sprinkles or chocolate curls before the ganache sets.
-
Serve and enjoy: Once the ganache is set, slice your cake and serve! Each slice is sure to bring smiles and delightful flavor to your dessert table.
Optional: Garnish with a sprinkle of cocoa powder for an extra touch!

Expert Tips for Guinness Chocolate Cake
Choose Quality Beer: Use a good quality Guinness for the best flavor. Cheap beers may lack the rich depth necessary for this Guinness Chocolate Cake with Irish Buttercream.
Avoid Overmixing: Stir the batter until just combined to prevent a dense cake. Overmixing can lead to tough texture, so be gentle!
Test for Doneness: When baking, check for doneness a few minutes early. Every oven is different, and overbaking can dry out your cake.
Cool Completely: Always allow your cakes to cool completely before frosting. Frosting a warm cake can lead to melting, creating a messy finish.
Crumb Coat Essentials: Don’t skip the crumb coat! It locks in crumbs, ensuring a smooth buttercream finish that’ll impress everyone at your gathering.
Decorate with Flair: Get creative with toppings! Sprinkles or chocolate curls add visually appealing touches and elevate the overall presentation of your Guinness Chocolate Cake.
How to Store and Freeze Guinness Chocolate Cake

Freezer: You can freeze the cake layers unfilled for up to 3 months. Wrap each layer tightly in plastic wrap and then in aluminum foil to prevent freezer burn.
Reheating: When you’re ready to enjoy it, let the frozen layers thaw in the fridge overnight. Reheat individual slices in the microwave for a few seconds to restore its warmth and tenderness.
Frosting Storage: If you have leftover Irish buttercream, store it in the fridge for up to a week in an airtight container. Re-whip before using to regain that light, fluffy texture.
