Guinness Chocolate Cake Ingredients
For the Cake
• All-purpose flour – Provides structure to the cake; consider cake flour for an even lighter texture.
• Granulated sugar – Sweetens and enhances browning; ensure even distribution for the best results.
• Unsweetened cocoa powder – Adds rich chocolate flavor; Dutch-process cocoa can deepen the cake’s color.
• Baking soda – Acts as a leavening agent, helping the cake rise beautifully.
• Baking powder – Works in conjunction with baking soda for extra fluffiness in your cake.
• Fine sea salt – Enhances flavors and balances the cake’s sweetness perfectly.
• Sour cream (or yogurt) – Adds moisture and richness; buttermilk makes for a tangy twist.
• Vegetable oil – Keeps the cake incredibly moist; melted butter? Use it for a richer flavor.
• Large eggs – Provide stability and structure; using room temperature eggs helps in emulsification.
• Vanilla extract – Adds depth to the cake’s chocolatey flavor profile.
• Guinness beer – Infuses the cake with a robust flavor; substitute with a non-alcoholic stout if desired.
For the Irish Buttercream
• Unsalted butter – The base of the frosting; ensure it’s at cool room temperature for the best texture.
• Powdered sugar – Sweetens and thickens the buttercream; sifted for a smooth finish.
• Irish cream (such as Bailey’s) – A key component for that classic creamy flavor; replace with heavy cream if avoiding alcohol.
For the Ganache
• Semisweet or bittersweet chocolate – Rich chocolate flavor for your ganache; use high-quality chocolate for the best taste.
• Heavy cream – Creates a luscious drip for the ganache; can be replaced with milk for a lighter version.
For Decoration
• Sprinkles or chocolate curls – Optional decorations that add a festive touch to your beautiful cake.

How to Make Guinness Chocolate Cake
-
Preheat the oven: Start by preheating your oven to 350°F (175°C). This ensures your cake bakes evenly and comes out perfectly. Don’t forget to generously grease two 8-inch round pans and line them with parchment paper.
-
Combine dry ingredients: In a large bowl, whisk together the all-purpose flour, granulated sugar, cocoa powder, baking soda, baking powder, and fine sea salt. This mix creates a fluffy base for your cake.
-
Mix wet ingredients: In another bowl, whisk together the large eggs, sour cream, vegetable oil, vanilla extract, and Guinness beer. Ensure everything is well combined for a smooth batter.
-
Combine mixtures: Carefully pour the wet ingredients into the dry mix. Gently fold them together until just combined; overmixing can lead to a dense cake, so be mindful!
-
Bake the cake: Divide the batter equally between your prepared pans. Slide them into the oven and bake for 35-40 minutes or until a toothpick inserted into the center comes out clean.
-
Cool the layers: Once baked, let the cakes cool in the pans for about 30 minutes before transferring them to a wire rack. Allow them to cool completely to avoid melting your frosting later.
-
Prepare the buttercream: For the Irish buttercream, beat the unsalted butter in a bowl until fluffy. Gradually add the powdered sugar and Irish cream, mixing until smooth and creamy.
-
Assemble the cake: Frost the top of the first layer generously with the buttercream, then place the second layer on top. Don’t forget to frost the sides and top, making it look extra delightful!
-
Crumb coat: Apply a thin layer of frosting all around to catch any crumbs. Chill the cake in the fridge for about 20-30 minutes to set this coat before adding a final layer of frosting.
-
Make the ganache: Heat the heavy cream in a small saucepan until simmering. Pour it over the chopped semisweet or bittersweet chocolate, then stir until smooth and glossy.
-
Drizzle the ganache: Allow the ganache to cool slightly before pouring it over the top of your frosted cake, letting it drip down the sides for that decadent look.
-
Decorate: Finish your cake with sprinkles or chocolate curls for an enticing touch. It’s all about those finishing details!
Optional: Add a sprinkle of sea salt on top of the ganache for a delightful contrast!

Make Ahead Options
These Guinness Chocolate Cake with Irish Buttercream components are perfect for meal prep, making your baking experience even more enjoyable! You can prepare the cake layers up to 3 days in advance; simply cool them completely, wrap in plastic wrap, and refrigerate to keep them moist. Want to save even more time? You can also make the Irish buttercream up to 24 hours ahead—just store it in an airtight container in the refrigerator. When you’re ready to assemble the cake, allow the buttercream to soften at room temperature, then frost as directed. This approach ensures your cake remains just as delicious when serving, while freeing up your busy schedule!
Expert Tips for Guinness Chocolate Cake
-
Measure Accurately: Ensuring precise measurements, especially for flour and cocoa, prevents dense or dry cake. Use a kitchen scale for accuracy!
-
Room Temperature Ingredients: Allow eggs, butter, and sour cream to come to room temperature. This helps create a smooth batter and ensures even baking in your Guinness Chocolate Cake.
-
Don’t Overmix: Gently combine wet and dry ingredients until just blended. Overmixing can lead to a tough cake—nobody wants that!
-
Cool Completely: Allow layers to cool fully before frosting to prevent melting your Irish buttercream. Patience here leads to a flawless finish!
-
Ganache Consistency: If your ganache is too thick, gently reheat it in the microwave to achieve the perfect drizzle for your cake.

Guinness Chocolate Cake with Irish Buttercream Recipe FAQs
What type of Guinness is best for baking this cake?
Absolutely! When making Guinness Chocolate Cake, I recommend using a classic stout, like the original Guinness Draught. Its rich, dark flavor beautifully enhances the chocolate, making the cake incredibly flavorful. If you want a non-alcoholic version, any quality non-alcoholic stout will work just as well.
How should I store leftover Guinness Chocolate Cake?
Store leftover cake covered at room temperature for up to 3 days to maintain its moisture and flavor. If you prefer, you can refrigerate it tightly wrapped to extend its life for about a week. Just remember, the texture may vary slightly after refrigeration!
Can I freeze the Guinness Chocolate Cake?
Yes! For longer storage, freeze your cake layers individually wrapped in plastic wrap followed by aluminum foil for up to 2 months. To enjoy, simply thaw overnight in the fridge before frosting or serving. This way, the cake retains its incredible moisture and flavor.
What should I do if my cake sinks in the middle?
If your cake sinks, it’s usually due to overmixing or incorrect oven temperatures. Ensure you’re mixing gently until just combined. Use an oven thermometer to verify your oven’s accuracy, as baking at higher temperatures can cause a cake to rise too quickly and then collapse.
Can I modify this recipe to be gluten-free or dairy-free?
Very much so! To make a gluten-free version of this delightful Guinness Chocolate Cake, substitute the all-purpose flour with a gluten-free blend designed for baking. For dairy-free, use plant-based sour cream and butter alternatives, along with a dairy-free stout. These modifications will still keep your cake deliciously moist and fudgy!
Is this cake safe for my dog to eat?
No, it is not safe. While chocolate is a common ingredient, it’s toxic to dogs. Always keep chocolate cakes and other desserts out of reach of your pets to ensure their safety.
