Guinness Chocolate Cake Ingredients
For the Cake
• Nonstick Baking Spray – Keeps the cake from sticking to the bundt pan for easy release.
• Granulated Sugar – Sweetens the cake; feel free to swap with coconut sugar for a less refined option.
• Light Brown Sugar – Adds moisture and a deeper flavor; no direct substitute, but more granulated sugar can work.
• All-Purpose Flour – Provides structure; can be substituted with a gluten-free flour mix if needed.
• Unsweetened Cocoa Powder – Enhances the rich chocolate flavor; consider using Dutch-processed cocoa for a more intense taste.
• Espresso Powder – Intensifies the chocolate flavor; strong coffee can be used if you don’t have this on hand.
• Baking Soda – Ensure it’s fresh for proper rise; it acts as a leavening agent.
• Baking Powder – Additional leavening for a fluffy cake; cannot be replaced with baking soda.
• Salt – Enhances the cake’s flavors; kosher salt works well as a substitute.
• Large Eggs (5) – Provides structure and moisture; substitute with flax eggs for a vegan option.
• Full-Fat Sour Cream – Adds richness and moisture; plain Greek yogurt can be a good alternative.
• Guinness Beer (8 oz) – Offers a unique flavor profile; other stout beers can be used as a substitute.
• Vegetable Oil – Keeps the cake moist; can switch to melted coconut oil if preferred.
• Whole Milk (½ cup) – Adds moisture; consider using buttermilk for extra flavor or a dairy-free alternative if needed.
• Vanilla Extract – Enhances the cake’s flavor; skip if unavailable, understanding that it may change the taste.
For the Baileys Buttercream
• Unsalted Butter – Creates a rich texture; if using salted butter, omit additional salt in the recipe.
• Confectioners’ Sugar – Sweetens the frosting and aids in achieving texture; no alternative suggested for a flawless finish.
• Baileys Irish Cream (3 tbsp) – Introduces a delightful flavor; substitute with heavy cream for a non-alcoholic version.
• Whole Milk (for Buttercream) – Adds creaminess; feel free to use more Baileys instead for richer flavor.
• Vanilla Extract (for Buttercream) – Elevates the frosting’s flavor; optional if omitted.
• Salt (for Buttercream) – Balances sweetness; adjust to taste as desired.

Step‑by‑Step Instructions for Guinness Chocolate Cake (Best St. Patrick’s Day Dessert)
Step 1: Preheat Oven
Preheat your oven to 325°F (163°C), allowing it to fully heat before baking. This ensures even cooking and a beautifully risen cake. As the oven warms, prepare your 10-cup bundt pan by generously spraying it with nonstick baking spray to prevent sticking and ensure an easy release of your luscious Guinness Chocolate Cake later.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together the granulated sugar, light brown sugar, all-purpose flour, unsweetened cocoa powder, espresso powder, baking soda, baking powder, and salt. Stir until all ingredients are thoroughly combined and no lumps remain. This step is crucial for the cake’s texture, as a well-mixed dry mixture helps create a light and airy cake.
Step 3: Combine Wet Ingredients
In another bowl, whisk the eggs, full-fat sour cream, Guinness, whole milk, vegetable oil, and vanilla extract until the mixture is smooth and fully blended. The combination of these ingredients will create a rich moisture that enhances the flavor of the Guinness Chocolate Cake. Make sure everything is well incorporated for the best results.
Step 4: Combine Mixtures
Pour the wet mixture into the bowl of dry ingredients, using a spatula to gently stir until just combined. Be careful not to overmix at this stage; you want a few small lumps to ensure the cake remains tender. This balance is key to creating a moist and decadent texture for your Guinness Chocolate Cake.
Step 5: Pour Batter into Pan
Transfer the batter into the prepared bundt pan, using a spatula to ensure an even spread. Gently tap the pan on the countertop to release any air bubbles trapped within the batter. This helps in achieving a uniform rise and prevents any unsightly holes in your finished cake.
Step 6: Bake the Cake
Place the bundt pan in the preheated oven and bake for about 50 minutes, or until a toothpick inserted in the center comes out clean. Keep an eye on the cake during the last few minutes; you want it to be set but not overbaked, ensuring it retains its moistness and rich flavor.
Step 7: Cool the Cake
Once baked, remove your Guinness Chocolate Cake from the oven and let it cool in the pan for 15 minutes. This resting time allows the cake to firm up slightly, making it easier to pop out of the pan without breaking. After this, carefully invert the bundt pan onto a cooling rack to let the cake cool completely.
Step 8: Prepare Baileys Buttercream
While the cake is cooling, you can start preparing the Baileys Buttercream. In a large mixing bowl, beat the unsalted butter until it’s smooth and creamy. Gradually add the confectioners’ sugar, mixing on low until well incorporated, then blend in the Baileys Irish Cream, whole milk, vanilla extract, and salt until the frosting is fluffy and spreadable.
Step 9: Frost the Cake
Once the cake has completely cooled, generously frost the top with your delicious Baileys Buttercream. To enhance the visual appeal, allow some frosting to cascade down the sides of the cake, creating an enticing presentation. This creamy topping not only adds flavor but transforms your Guinness Chocolate Cake into a show-stopping dessert.
Step 10: Optional Caramel Drizzle
For an extra touch of decadence, consider making the optional Irish whiskey salted caramel. In a small saucepan, cook sugar and water until dissolved, then stir in butter and let it boil until it turns a deep golden color. Remove from heat and mix in cream and whiskey, allowing the sauce to cool before drizzling it artistically over your frosted cake.

How to Store and Freeze Chocolate Guinness Bundt Cake
Room Temperature: Store the cake at room temperature in an airtight container for up to 2 days. This keeps it fresh and moist for immediate enjoyment.
Fridge: For longer storage, refrigerate the cake in an airtight container for up to 1 week. This prevents spoilage while preserving the delicious flavor of your Chocolate Guinness Bundt Cake.

Reheating: To enjoy frozen slices, simply thaw in the fridge overnight and reheat in the microwave for 10-15 seconds, or until just warmed.

Expert Tips for Chocolate Guinness Bundt Cake

Chocolate Guinness Bundt Cake Recipe FAQs
How do I select ripe and quality ingredients for the cake?
Absolutely! For the best results, choose large eggs that are fresh, without any cracks. Look for sour cream that’s rich and creamy, as it adds moisture to the cake. When selecting flour, you want to ensure that it’s fresh and free from lumps, while cocoa powder should be high-quality to enhance the chocolate flavor. For the Guinness, try to pick a can or bottle that hasn’t been sitting on the shelf too long; the fresher the beer, the better the taste!
What is the best way to store leftover chocolate Guinness bundt cake?
Very good question! To keep your cake fresh for about 1 to 2 days at room temperature, store it in an airtight container. If you want to extend its life, place it in the refrigerator, where it will last for up to a week. Just remember to let it come to room temperature before serving for the best taste and texture!
Can I freeze leftover chocolate Guinness bundt cake?
Yes, definitely! To freeze your cake, first slice it into individual pieces to make defrosting easier. Wrap each slice tightly in plastic wrap and then in foil, ensuring no air gets in. You can freeze it for up to 3 months. When you’re ready to enjoy, simply thaw the slices in the fridge overnight and give them a quick microwave zap for 10-15 seconds to warm them up!
What do I do if my cake turns out dense?
Don’t worry, it happens! A dense cake typically results from overmixing. When combining the wet and dry ingredients, mix until just combined—it’s okay if there are a few lumps remaining. Also, ensure that your ingredients, like the eggs and butter, are at room temperature before mixing. This helps create a smoother batter and a lighter cake!
Is this cake safe for people with dietary restrictions, such as allergies?
For those with dietary considerations, this Chocolate Guinness Cake can be allergenic due to eggs, dairy, and gluten. You can easily adjust it by using flax eggs instead of regular eggs for a vegan version and substituting plain Greek yogurt with dairy-free alternatives. Additionally, swap out all-purpose flour for a gluten-free blend to make it suitable for those with gluten sensitivities. Just ensure that all substitutes align with your dietary needs!
Can I make this cake without alcohol?
Of course! If you wish to skip the alcohol, you can replace the Guinness with a non-alcoholic stout—or simply use strong brewed coffee to retain that rich flavor profile. For the Baileys in the buttercream, heavy cream works wonderfully as a substitute. Your cake will still be incredibly delicious and a treat for everyone!
