What is a Guinness Chocolate Cake?
Guinness Chocolate Cake is a moist, dense cake that incorporates Guinness stout beer into the batter. The bitterness of the stout intensifies the rich chocolate flavor while adding depth and complexity. This type of cake is often finished with a tangy cream cheese frosting, which balances the cake’s richness with a light, creamy contrast. The result is a dessert that’s full of robust flavors, perfect for chocolate and beer lovers alike.
Ingredients List for Guinness Chocolate Cake
To make this rich and flavorful cake, you’ll need the following ingredients:
- 1 cup (240 ml) Guinness stout
(The star ingredient! Guinness gives the cake a rich, malty flavor and enhances the chocolate.) - 1 cup (2 sticks) unsalted butter
(Butter adds richness and moisture to the cake.) - ¾ cup unsweetened cocoa powder
(Cocoa powder provides deep chocolate flavor.) - 2 cups granulated sugar
(Sugar sweetens the cake and balances the bitterness of the stout and cocoa.) - ¾ cup sour cream
(Sour cream keeps the cake tender and moist.) - 2 large eggs
(Eggs provide structure and help bind the ingredients together.) - 1 tablespoon vanilla extract
(Vanilla adds depth and enhances the flavors of the cake.) - 2 cups all-purpose flour
(All-purpose flour gives the cake structure.) - 2 ½ teaspoons baking soda
(Baking soda helps the cake rise and creates a light, airy texture.)
Ingredients List for Cream Cheese Frosting
The cream cheese frosting is a perfect match for the Guinness Chocolate Cake, providing a creamy, tangy contrast to the rich cake:
- 8 oz (1 package) cream cheese, softened
(Cream cheese creates a smooth, tangy base for the frosting.) - 1 cup (2 sticks) unsalted butter, softened
(Butter makes the frosting creamy and rich.) - 4 cups powdered sugar
(Powdered sugar sweetens the frosting and gives it a light, fluffy texture.) - 2 teaspoons vanilla extract
(Vanilla enhances the flavor of the frosting.)
Substitutions and Variations
Guinness Chocolate Cake can be customized with different ingredients and flavors to suit your preferences:
- Gluten-Free Option: Use a gluten-free flour blend in place of the all-purpose flour. Be sure to use one that’s designed for baking to get the best results.
- Vegan Option: Replace the eggs with flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg), use a plant-based butter substitute, and swap sour cream for a dairy-free alternative like coconut yogurt.
- Flavor Variations: For a coffee-chocolate twist, replace ¼ cup of the Guinness with brewed coffee. This enhances the depth of the chocolate flavor.
- Boozy Frosting: For an extra kick, add a tablespoon or two of Irish cream liqueur (like Baileys) to the cream cheese frosting.
Step-by-Step Cooking Instructions

Let’s walk through the process of making this decadent cake step by step. It’s easy to follow and delivers a moist, flavorful cake every time!
Step 1: Preheat the Oven and Prepare the Pan
Preheat your oven to 350°F (175°C). Grease and line a 9-inch round cake pan (or a springform pan) with parchment paper. This will help the cake release easily after baking.
Step 2: Heat the Guinness and Butter
In a medium saucepan, combine the Guinness and butter. Heat over medium heat until the butter is melted and the mixture is smooth. Remove from heat and whisk in the cocoa powder until smooth and fully incorporated. Set the mixture aside to cool slightly.
Step 3: Mix the Wet Ingredients
In a large mixing bowl, whisk together the sugar, sour cream, eggs, and vanilla extract until smooth and creamy.
Step 4: Combine Wet and Dry Ingredients
Slowly pour the slightly cooled Guinness-chocolate mixture into the sugar and sour cream mixture, stirring constantly. Mix until fully combined.
Step 5: Add the Dry Ingredients
In a separate bowl, whisk together the flour and baking soda. Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Be careful not to overmix the batter, as this can make the cake dense.
Step 6: Bake the Cake
Pour the batter into the prepared cake pan and smooth the top with a spatula. Bake in the preheated oven for 45-50 minutes, or until a toothpick inserted into the center of the cake comes out clean. The cake should have a firm, slightly domed top.
Step 7: Cool the Cake
Allow the cake to cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely before frosting.
How to Cook Guinness Chocolate Cake: A Step-by-Step Guide
Making the perfect Guinness Chocolate Cake is all about combining the deep, rich flavors of stout and chocolate with the right balance of sweetness and texture. The cake bakes for just under an hour, but it’s important to let it cool completely before adding the cream cheese frosting, so the frosting doesn’t melt or slide off.
Common Mistakes to Avoid
While this recipe is fairly simple, there are a few common mistakes that can impact your cake’s texture and flavor. Here’s how to avoid them:
- Overmixing the batter: After adding the flour, mix just until combined. Overmixing can lead to a dense, tough cake.
- Not cooling the cake before frosting: If the cake is still warm, the frosting will melt and slide off. Be patient and let the cake cool completely.
- Using cold ingredients: Make sure your butter, eggs, and sour cream are at room temperature for even mixing and a smoother batter.
Serving and Presentation Tips
Once your cake is frosted and ready to serve, here are a few tips to make it look and taste even more impressive:
- Dust with Cocoa Powder: Before serving, dust the top of the cream cheese frosting with a light sprinkling of cocoa powder for an elegant finish.
- Top with Chocolate Shavings: Add dark chocolate shavings or curls on top of the frosting to enhance the chocolate flavor and give the cake a more luxurious appearance.
- Serve with Fresh Berries: Serve slices of the cake with fresh berries like raspberries or strawberries. The tartness of the fruit complements the richness of the cake beautifully.
How to Serve Guinness Chocolate Cake
Guinness Chocolate Cake is best served at room temperature so the cake is soft and the frosting is creamy. You can serve it as-is or pair it with a scoop of vanilla or chocolate ice cream for an extra indulgent treat. A cup of coffee or even a glass of Guinness is a great accompaniment!
Presentation Ideas for Guinness Chocolate Cake
- Pint of Guinness Look: To make the cake resemble a pint of Guinness, frost the top with a generous layer of cream cheese frosting, leaving the sides unfrosted. This gives the cake a look similar to a pint of Guinness with its famous frothy head.
- Layer Cake: If you want to take it up a notch, you can slice the cake in half horizontally and add a layer of cream cheese frosting in the middle before frosting the top.
- Mini Cakes: Use small cake pans to create individual Guinness Chocolate mini cakes. These are perfect for serving at parties or special events.
Guinness Chocolate Cake Recipe Tips
- Make Ahead: You can make the cake a day in advance and store it in the fridge, but be sure to let it come to room temperature before serving for the best flavor and texture.
- Chill the Frosting: If your cream cheese frosting is too soft to spread, pop it in the fridge for 10-15 minutes to firm up before frosting the cake.
- Storage: Store leftover cake in an airtight container in the refrigerator for up to 5 days. The cake will remain moist, and the cream cheese frosting will stay fresh.
Frequently Asked Questions (FAQs)
- Can I make this cake without Guinness?
Yes! If you prefer to omit the Guinness, you can substitute it with strong coffee or milk. However, the stout enhances the chocolate flavor, so it will taste a bit different without it. - Can I freeze Guinness Chocolate Cake?

Absolutely! Just divide the batter into cupcake liners and bake at 350°F (175°C) for about 18-20 minutes, or until a toothpick comes out clean. - What if I don’t have sour cream?
You can substitute sour cream with plain Greek yogurt or buttermilk for a similar texture and tangy flavor.
