What is Guinness Chocolate Cake?
Guinness Chocolate Cake is a luxurious chocolate cake that incorporates Guinness stout beer into the batter. The beer enhances the chocolate flavor, making it more intense and rich, without overpowering the sweetness of the cake. Guinness, known for its deep, malty notes, adds a slight bitterness and complexity that balances perfectly with the sweetness of the sugar and the bitterness of the cocoa. This cake is often topped with a creamy, tangy frosting—usually cream cheese or whipped cream—to complement the richness of the chocolate. The result is a moist, dense cake with a unique flavor that is perfect for any celebration.
Ingredients List for Guinness Chocolate Cake
Here’s everything you need to make this decadent Guinness Chocolate Cake:
For the Cake:
- 1 cup (240 ml) Guinness Stout Beer – The star ingredient! This gives the cake its deep, malty flavor.
- 1 cup (2 sticks) unsalted butter – Adds richness and moisture to the cake.
- ¾ cup unsweetened cocoa powder – Provides that intense chocolate flavor.
- 2 cups granulated sugar – Sweetens the cake and balances the bitterness of the beer and cocoa.
- ¾ cup sour cream – Adds moisture and a slight tang that complements the richness of the chocolate.
- 2 large eggs – Bind the ingredients together and help the cake rise.
- 1 tablespoon vanilla extract – Enhances the flavor of the cake.
- 2 cups all-purpose flour – The base of the cake that provides structure.
- 2 ½ teaspoons baking soda – Ensures the cake rises and gives it a light texture.
- ¼ teaspoon salt – Balances and enhances the flavors.
For the Frosting (Cream Cheese Frosting):
- 8 oz (1 package) cream cheese, softened – The tangy base for the frosting.
- ½ cup (1 stick) unsalted butter, softened – Adds creaminess to the frosting.
- 3 to 4 cups powdered sugar – Sweetens and thickens the frosting.
- 1 teaspoon vanilla extract – Adds flavor and sweetness.
- 2 to 3 tablespoons heavy cream (optional) – To achieve the desired frosting consistency.
Substitutions and Variations
Here are some substitutions and variations to customize your Guinness Chocolate Cake:
- Non-alcoholic beer: If you prefer to avoid alcohol, you can substitute a non-alcoholic stout for Guinness. The flavor won’t be exactly the same, but it will still be rich and delicious.
- Different stouts: While Guinness is the traditional beer for this recipe, you can experiment with other stouts, such as chocolate stout or oatmeal stout, for a slightly different flavor profile.
- Gluten-free option: Swap out the all-purpose flour with a 1-to-1 gluten-free flour blend if you want to make a gluten-free version.
- Dairy-free version: You can use dairy-free butter and dairy-free sour cream to make this cake suitable for those with dairy intolerances. Coconut cream can also be used to make a dairy-free frosting.
- Chocolate ganache frosting: Instead of cream cheese frosting, you can top your cake with a rich chocolate ganache made from chocolate and heavy cream.
- Cupcake version: Turn this cake recipe into individual cupcakes by adjusting the baking time to about 18-20 minutes.
- Add mix-ins: Enhance the texture by adding chocolate chips or chopped nuts to the batter for an extra layer of indulgence.
Step-by-Step Cooking Instructions

Let’s dive into the detailed process of making this delicious Guinness Chocolate Cake.
Step 1: Prepare the Oven and Pan
Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan or line it with parchment paper for easy removal.
Step 2: Melt the Butter and Guinness
In a medium saucepan, combine the Guinness and butter over medium heat. Stir occasionally until the butter is completely melted and combined with the beer. Remove from heat and whisk in the cocoa powder until smooth. Set aside to cool slightly.
Step 3: Mix the Dry Ingredients
In a large bowl, whisk together the flour, sugar, baking soda, and salt. This ensures even distribution of the leavening agent and salt.
Step 4: Combine Wet Ingredients
In a separate bowl, beat together the eggs, sour cream, and vanilla extract until well combined. Slowly pour the slightly cooled Guinness mixture into the egg mixture, stirring constantly to prevent the eggs from cooking.
Step 5: Combine Wet and Dry Ingredients
Slowly add the wet mixture to the dry ingredients, stirring until everything is just combined. Be careful not to overmix, as this can lead to a dense cake.
Step 6: Bake the Cake
Pour the batter into the prepared pan and smooth the top. Bake in the preheated oven for 45-50 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
How to Cook Guinness Chocolate Cake: A Step-by-Step Guide
- Preheat the Oven: Set your oven to 350°F (175°C) to ensure it's ready when you are.
- Prepare the Beer Mixture: Melt the butter with the Guinness stout in a saucepan, then mix in the cocoa powder to create a smooth, chocolatey base.
- Whisk the Dry Ingredients: Combine flour, sugar, baking soda, and salt in a large bowl.
- Mix Wet Ingredients: Beat the eggs, sour cream, and vanilla, then incorporate the Guinness mixture.
- Combine: Gently mix the wet and dry ingredients together until fully combined.
- Bake: Pour the batter into a cake pan and bake for 45-50 minutes until a toothpick comes out clean.
- Cool: Let the cake cool completely before frosting.
Common Mistakes to Avoid
- Overmixing the batter: Mixing the batter too much can result in a dense cake. Stir until just combined.
- Using cold ingredients: Make sure your ingredients, especially butter, sour cream, and eggs, are at room temperature for a smoother batter.
- Not allowing the Guinness mixture to cool: If the Guinness-butter mixture is too hot when added to the egg mixture, it can cook the eggs and ruin the batter.
- Skipping the frosting: The cream cheese frosting adds a tangy balance to the rich cake. Don’t skip it!
Serving and Presentation Tips
Guinness Chocolate Cake is visually stunning when served as a single-layer cake with a generous topping of frosting, but you can also slice it and layer it with extra frosting between each layer for added elegance.
How to Serve Guinness Chocolate Cake
- With whipped cream: If you prefer something lighter than cream cheese frosting, serve the cake with freshly whipped cream.
- With fresh berries: Add a pop of color and freshness with strawberries, raspberries, or blackberries on the side.
- A dusting of cocoa: For a more minimalist presentation, you can dust the top of the cake with cocoa powder or powdered sugar.
Presentation Ideas for Guinness Chocolate Cake
- Rustic look: Keep the frosting simple, spreading it over the top of the cake with a spatula for a homemade, rustic appearance.
- Drizzle with ganache: Add a chocolate ganache drizzle for a luxurious touch.
- Add edible flowers: Garnish with edible flowers or gold leaf for an elegant, high-end presentation.
Guinness Chocolate Cake Recipe Tips
- Use quality chocolate: The richer the cocoa, the better your cake will taste.
- Let the cake cool completely: Frosting a warm cake can cause the frosting to melt and slide off.
- Chill the frosting: For a cleaner look, chill the frosting for 20 minutes before applying it to the cake.
