Why This is the Best Chocolate Guinness Cake Recipe
This isn’t just another chocolate cake; it’s an experience. The secret lies in how the ingredients work together to create something truly special.
- Incredibly Moist Crumb: The Guinness stout not only adds flavor but its acidity and carbonation react to create a super tender, moist texture that lasts for days.
- Deep, Complex Flavor: The roasted, malty notes of the Guinness amplify the cocoa powder, resulting in a chocolate flavor that is deep and complex, not just sweet.
- Perfectly Balanced: The slightly bitter notes from the stout and cocoa are perfectly balanced by a sweet, tangy cream cheese frosting that cuts through the richness beautifully.
- Surprisingly Easy: While it sounds and tastes gourmet, the method is straightforward. It’s a simple melt, mix, and bake process that any home baker can master.
What You’ll Need
The key is using good quality ingredients. For the best flavor, use a classic Guinness Draught stout and high-quality unsweetened cocoa powder.
For the Chocolate Guinness Cake
- Guinness Stout: The star of the show. It provides moisture and a deep, malty flavor.
- Unsalted Butter: Adds richness and structure.
- Unsweetened Cocoa Powder: For that intense, dark chocolate flavor. Use natural, not Dutch-processed.
- Granulated Sugar: Sweetens the cake and helps create a tender crumb.
- All-Purpose Flour: Provides the main structure for the cake.
- Baking Soda: The leavening agent that reacts with the acidic stout and sour cream.
- Salt: Balances all the flavors.
- Large Eggs: Binds the ingredients together.
- Sour Cream: Adds extra moisture and a slight tang.
- Vanilla Extract: Enhances the chocolate and malt flavors.
For the Cream Cheese Frosting
- Cream Cheese: Use full-fat, block-style cream cheese for the best texture. It should be softened to room temperature.
- Unsalted Butter: Also softened to room temperature for a smooth, creamy consistency.
- Confectioners’ Sugar: Sift it to avoid any lumps in your frosting.
- Heavy Cream: Helps to achieve the perfect spreadable consistency.
- Vanilla Extract: For flavor.

Ingredients
Equipment
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour a 9-inch springform pan, or line the bottom with parchment paper and grease the sides.
- In a large saucepan over medium-low heat, combine the Guinness and butter. Heat gently until the butter is completely melted. Remove from the heat and whisk in the cocoa powder and granulated sugar until smooth. Set aside to cool slightly.
- In a separate large bowl, whisk together the all-purpose flour, baking soda, and salt.
- In a medium bowl, whisk together the eggs, sour cream, and vanilla extract until well combined.
- Pour the slightly cooled Guinness mixture into the dry ingredients and whisk until just combined. Add the egg mixture and whisk gently until the batter is smooth. Do not overmix.
- Pour the batter into the prepared pan. Bake for 45-55 minutes, or until a wooden skewer inserted into the center comes out clean. Let the cake cool in the pan for 15-20 minutes before releasing the sides. Cool completely on a wire rack.
- In a large bowl, beat the softened cream cheese and butter on medium-high speed until light and fluffy, about 2-3 minutes.
- Reduce speed to low and gradually add the sifted confectioners’ sugar. Once incorporated, add the vanilla and heavy cream. Increase speed to medium-high and beat for another 2-3 minutes until smooth and creamy.
- Once the cake is completely cool, spread the cream cheese frosting evenly over the top, creating rustic swirls.
Notes
Do not overmix the cake batter, as this can result in a tough cake.
Let the cake cool completely before frosting to prevent the frosting from melting.
Step 1: Prepare the Guinness & Butter Mixture
Preheat your oven to 350°F (175°C). Grease and flour a 9-inch springform pan, or line the bottom with parchment paper and grease the sides. In a large saucepan over medium-low heat, combine the Guinness and butter. Heat gently, stirring occasionally, until the butter is completely melted. Remove from the heat and whisk in the cocoa powder and granulated sugar until smooth. Set aside to cool slightly.
Step 2: Combine the Dry Ingredients
In a separate large bowl, whisk together the all-purpose flour, baking soda, and salt. This ensures the leavening is evenly distributed, which is key for a perfect rise.
Step 3: Mix the Wet Ingredients
In a medium bowl, whisk together the eggs, sour cream, and vanilla extract until well combined and smooth.
Step 4: Combine and Bake
Pour the slightly cooled Guinness mixture into the dry ingredients and whisk until just combined. Then, add the egg and sour cream mixture and whisk gently until the batter is smooth. Be careful not to overmix! Pour the batter into your prepared pan. Bake for 45-55 minutes, or until a wooden skewer inserted into the center comes out clean. Let the cake cool in the pan on a wire rack for 15-20 minutes before releasing the sides. Allow it to cool completely before frosting.
Step 5: Make the Cream Cheese Frosting
While the cake cools, prepare the frosting. In a large bowl using a hand mixer or in the bowl of a stand mixer fitted with the paddle attachment, beat the softened cream cheese and butter on medium-high speed until light and fluffy, about 2-3 minutes. Reduce the speed to low and gradually add the sifted confectioners’ sugar. Once incorporated, add the vanilla and heavy cream. Increase the speed to medium-high and beat for another 2-3 minutes until the frosting is smooth and creamy.
Step 6: Assemble and Frost the Cake
Once the cake is completely cool—and this is very important—place it on your serving plate or cake stand. Spread the cream cheese frosting evenly over the top of the cake. You can create swoops and swirls for a rustic look that mimics the foam on a pint of Guinness. A garnish of chocolate shavings is a lovely touch!
Tips for Success
Follow these simple tips to guarantee a perfect chocolate stout cake every time.
- Use Room Temperature Ingredients: For the frosting and the wet cake ingredients (eggs, sour cream), using room temperature components ensures they combine evenly, creating a smoother batter and creamier frosting.
- Don’t Overmix the Batter: Mix only until the ingredients are just combined. Overmixing develops the gluten in the flour, which can lead to a tough, dry cake instead of a tender one.
- Don’t Boil the Guinness: When melting the butter into the Guinness, use gentle heat. Boiling the stout can cook off some of the nuanced flavor we want in the final cake.
- Let the Cake Cool Completely: This is the golden rule of frosting! If you try to frost a warm cake, the frosting will melt into a soupy mess. Patience is key.
Ingredient Substitutions & Variations
While this recipe is fantastic as is, here are a few possible tweaks:
| Ingredient | Substitution Suggestion |
|---|---|
| Guinness Stout | You can use another dark stout or porter. For a non-alcoholic version, use a non-alcoholic stout or strong-brewed coffee. |
| Sour Cream | Full-fat plain Greek yogurt or buttermilk can be used in a 1:1 ratio. |
| Frosting | A simple chocolate ganache or a Bailey’s Irish Cream buttercream would also be delicious. |

Storing and Freezing Your Chocolate Stout Cake
This cake stores beautifully, making it a great option to prepare in advance.
Storing at Room Temperature or in the Refrigerator
Because of the cream cheese frosting, the cake should be stored in the refrigerator. Place it in an airtight container or cake carrier. It will stay fresh and moist for up to 4 days. Let it sit at room temperature for about 20-30 minutes before serving for the best flavor and texture.
Freezing the Cake
You can freeze the unfrosted cake layer. Once it’s completely cool, wrap it tightly in two layers of plastic wrap, followed by a layer of aluminum foil. It can be frozen for up to 3 months. Thaw it overnight in the refrigerator, then bring to room temperature before frosting and serving. You can also freeze individual frosted slices for an easy treat.
