Introduction to Guinness Chocolate Cake with Irish Buttercream
Why Guinness? The Secret Ingredient in This Cake
When you think of a rich chocolate cake, you probably don't immediately consider beer. However, in our Guinness Chocolate Cake with Irish Buttercream, the inclusion of Guinness is a game changer! This famous stout doesn't just add moisture; it brings a depth of flavor that transforms an ordinary chocolate cake into something extraordinary. The malty undertones and slight bitterness from the Guinness enhance the cocoa, creating a beautifully balanced dessert that’s not overly sweet.
You might wonder, "Can you actually taste the beer?" The answer is no! Instead, the beer acts as a flavor enhancer, making the cake fudgier and richer than you could ever imagine (and also a great conversation starter). This concept of using stout in baked goods is akin to the techniques found in various craft recipes—get the full scoop on the chemistry of baking on Serious Eats.
Plus, top it all off with a thick layer of Irish buttercream, flavored with creamy Irish cream liqueur, and you’ve got a match made in dessert heaven.

Step-by-Step Preparation of Guinness Chocolate Cake with Irish Buttercream
Making a mouthwatering Guinness Chocolate Cake with Irish Buttercream is easier than you might think! Let’s walk through the process step-by-step, ensuring every part of this decadent delight is clear and enjoyable for you.
Preheat the oven and prepare the pans
Start by preheating your oven to 350°F (175°C). While that's warming up, generously grease two 8-inch round cake pans with butter or nonstick spray. For an extra layer of assurance against sticking, line the bottoms with parchment paper rounds. This ensures that when the cake is done baking, it simply slips out of the pans!
Mix the dry ingredients
In a large mixing bowl, combine the following dry ingredients:
- 1 ¾ cups all-purpose flour
- 2 cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 2 teaspoons baking soda
- ½ teaspoon baking powder
- 1 teaspoon fine sea salt
Whisk these together until well blended. This step not only adds flavor but also air to your cake batter, making it lighter!
Combine the wet ingredients
In a separate medium bowl, whisk together the wet ingredients:
- ¾ cup sour cream or plain full-fat yogurt
- ½ cup vegetable oil
- 3 large eggs
- 1 teaspoon vanilla extract
- 1 cup Guinness beer
Ensure everything is at room temperature – it helps combine better and creates a more consistent batter.
Combine wet and dry ingredients
Now, pour the wet mixture into your dry ingredients. Stir gently with a spatula until just combined. Remember, it’s okay if there are a few lumps; overmixing can lead to a tough cake!
Bake the cake layers
Divide the batter evenly between the prepared pans. Bake in your preheated oven for 35 to 40 minutes, or until a cake tester or toothpick comes out clean from the center. Let the cakes cool in their pans for about 30 minutes before transferring them to a wire rack to cool completely.
Make the Irish buttercream
While your cakes are cooling, let’s whip up some amazing Irish Buttercream. In a large bowl, use an electric mixer to beat 4 sticks of unsalted butter until light and fluffy. Gradually add 6 cups of sifted powdered sugar and then stir in ¼ cup plus 2 tablespoons of Irish cream. Beat until fluffy and smooth – about 3 minutes should do it! If the frosting is too thick, feel free to add a splash more Irish cream.
Assemble the cake
Now it’s time to bring this masterpiece to life! Place one of your cake layers on a cake stand and generously frost the top. Then, place the second layer on top, flat side up, and apply a thin layer of frosting around the entire cake for the crumb coat. Pop it into the fridge for about 15-30 minutes to let this layer firm up.
Prepare the chocolate drip
While set, prepare the chocolate drip. In a heatproof bowl, combine 4 ounces of finely chopped chocolate with ½ cup heavy cream. Heat the cream until simmering, then pour it over the chocolate; let it sit for a few minutes before stirring until smooth. Let it cool for about 10 minutes until still pourable but thickened.
Drip and decorate the cake
Carefully pour a bit of the ganache over the top of the cake, spreading it to the edges. For elegance, use a squeeze bottle to add drips around the cake sides. Don't forget to add some fun toppings like sprinkles or chocolate curls before the ganache sets!
And there you have it! You just created a delicious Guinness Chocolate Cake with Irish Buttercream, perfect for sharing with friends on St. Patrick's Day or any day you need a chocolate boost. Enjoy every bite!

Variations on Guinness Chocolate Cake
Gluten-free adaptations
If you're looking to make a delightful Guinness Chocolate Cake with Irish Buttercream that caters to gluten sensitivity, you can easily swap out the all-purpose flour for a high-quality gluten-free flour blend. Keep an eye on your measurements, as they might vary slightly. Additionally, ensure your baking powder and soda are gluten-free, and opt for naturally gluten-free ingredients for the buttercream, like pure vanilla extract.
Vegan options
Want to enjoy a Guinness Chocolate Cake without the eggs or dairy? No problem! Substitute the eggs with flaxseed meal or unsweetened applesauce, and replace the sour cream with vegan yogurt or silken tofu. For the buttercream, use a vegan butter alternative along with plant-based cream liqueur to maintain that creamy texture. These adaptations allow everyone to indulge in this festive treat, no matter their dietary preferences!

Cooking Tips and Notes for Guinness Chocolate Cake
Common Pitfalls and How to Avoid Them
Baking can be tricky, and even seasoned bakers might encounter hiccups. One common mistake is overmixing the batter, which can lead to a dense cake. Mix until just combined for that light and airy texture. Also, ensure your ingredients are at room temperature—this ensures your Guinness chocolate cake with Irish buttercream achieves the right blend. Lastly, don't skip the cooling step; allowing the cake to cool in pans prevents it from crumbling.
How to Achieve the Perfect Texture
For a wonderfully moist cake, use sour cream or full-fat yogurt. These ingredients add necessary moisture and richness. If you're aiming for a fluffy consistency in your buttercream, start with softened butter and gradually add sifted powdered sugar. A splash of Irish cream enhances not only flavor but texture as well. Make sure to avoid rushing the cooling process; a properly chilled cake will hold its shape and layers beautifully.

FAQs about Guinness Chocolate Cake
Can I substitute Guinness with another beer?

For the Chocolate Drip

Instructions
Make the cake
- Preheat the oven to 350°F. Generously grease two 8-inch wide x 3-inch deep cake pans and line with parchment paper rounds.
- In a large mixing bowl, whisk together the flour, sugar, cocoa, baking soda, baking powder, and salt.
- In a medium bowl, whisk together the sour cream, vegetable oil, eggs, vanilla, and beer.
- Add the wet ingredients into the dry ingredients and stir with a spatula until just combined, being careful not to overmix.
- Divide the batter between the prepared pans and bake for 35 to 40 minutes, or until a cake tester comes out clean. Cool the cakes in their pans for 30 minutes before carefully turning them out onto a cooling rack or wire rack to cool completely.
- If possible, freeze the cakes while you prepare the buttercream.
Make the buttercream
- In a large bowl, use an electric mixer or hand mixer to beat the butter until light and fluffy.
- Gradually add the sifted powdered sugar, then the Irish cream. Beat the mixture on high speed until very light, fluffy, and smooth, about 3 minutes.
- If the frosting is too thick, add a splash more Irish cream. If it’s too thin, add more powdered sugar.
Assemble
- Place one cake layer on a cake stand or serving plate. Frost the top of the cake generously, as this will become the filling.
- Top with the other cake layer, flat side up.
- With an offset spatula, spread a very thin layer of frosting all over the cake. This layer is a crumb coat and should act like spackle.
- For the smoothest frosting, return the cake to the fridge or freezer until firm to the touch.
- Spread the remaining frosting all over the cake. If desired, focus the frosting on the top to maintain the 'naked' look. Refrigerate while you prepare chocolate drip.
Make chocolate drip
- Place the chopped chocolate in a heatproof bowl. In a small pan, bring the heavy cream to a simmer then immediately remove from heat and pour over chocolate.
- You can also do this in the microwave. Cover for a few minutes then stir until smooth.
- Allow to cool until it has thickened but is still pourable, about 10 minutes. Don’t place ganache in the fridge to cool.
- Test the consistency of the drip by pouring down the side of a glass. If it’s too thick, microwave for 5 to 10 seconds. If it’s too thin, continue to cool.
- Carefully pour some of the ganache over the top of the chilled cake. Use an offset spatula to quickly smooth the ganache over the top of the cake before it sets.
- Use a squeeze bottle to gently squeeze one drip at a time down the sides of the cake.
- Before the ganache fully sets, add sprinkles, chocolate curls, or any other decor you like.
- This cake can be stored, covered with a cake keeper, at a cool, dry room temperature for 2-3 days.
