Ingredients You’ll Need
To create this show-stopping dessert, you’ll gather simple yet essential ingredients that each play their part in building the cake’s luscious texture and complex flavor profile. From the cocoa’s richness to the whiskey’s warmth, every element contributes to a perfect harmony.
- Unsalted butter: Using softened butter ensures a smooth batter and frosting with a creamy consistency that holds the cake together beautifully.
- Granulated sugar: This classic sweetener gives the cake its balanced sweetness without overpowering the stout’s deep notes.
- Large eggs: At room temperature, eggs blend effortlessly to provide structure and moisture that keep the cake tender.
- Vanilla extract: Adds a subtle aroma that enhances the chocolate and whiskey flavors in the cake and frosting.
- All-purpose flour: The base of the cake’s structure, allowing for a tender crumb that’s neither too dense nor too light.
- Baking soda and baking powder: These leaveners work together to give the cake its perfect rise and fluffy texture.
- Salt: A pinch to balance the sweetness and intensify the chocolate’s complex notes.
- Unsweetened cocoa powder: The star for that deep chocolate flavor and rich color that make this cake irresistible.
- Stout beer: One of the secret ingredients that brings moisture, a slightly bitter edge, and a beautiful malt depth to the cake.
- Powdered sugar: Used in the frosting, it makes the buttercream smooth and perfectly sweet.
- Whiskey: This adds that signature boozy warmth to the buttercream, elevating the whole dessert with a touch of sophisticated indulgence.
How to Make Chocolate Stout Cake with Whiskey Buttercream Frosting Recipe
Step 1: Prepare Your Oven and Pans
Start off by preheating your oven to 350 degrees to ensure it’s nice and hot when your batter is ready to go in. Grease and flour your cake pans thoroughly for easy release, then line the bottoms with round parchment paper circles. This little extra step ensures your beautiful cake layers come out without a hitch or crumbly disaster.
Step 2: Cream Butter and Sugar
In a large mixing bowl, cream together the softened butter and granulated sugar until the mixture is light and fluffy. This aerates the batter, which is essential for a tender crumb. Adding the eggs one at a time and mixing after each helps the eggs incorporate smoothly without curdling, building the cake’s structure gradually.
Step 3: Mix Dry Ingredients and Add Alternately with Stout
Combine your flour, baking soda, baking powder, salt, and unsweetened cocoa powder in a separate bowl. Slowly alternate adding this dry ingredient mix with the stout beer to your butter-sugar-egg mixture, mixing on low speed just until combined. This pouring technique keeps your batter smooth and prevents overmixing, which could make the cake tough.
Step 4: Bake the Cake Layers
Divide the batter evenly among your prepared pans. This ensures all layers bake at the same rate and stack evenly. Pop them into your preheated oven and bake for about 22 to 28 minutes, or until a toothpick inserted in the center comes out clean. Then, let the cakes cool completely before moving on to leveling and frosting.
Step 5: Prepare the Whiskey Buttercream Frosting
While your cakes cool, whip up the frosting by creaming softened butter and powdered sugar together until creamy and luscious. Add vanilla extract and whiskey, mixing on low speed to maintain that silky smooth texture without splattering. The whiskey adds an adult twist that pairs perfectly with the chocolate cake’s stout richness.
Step 6: Assemble and Frost Your Cake
Once cooled, level the tops of your cake layers using a cake leveler or serrated knife, ensuring even stacking and a professional look. Spread a generous amount of whiskey buttercream on each layer, stacking carefully. Finally, frost the top and sides with the remaining buttercream for a stunning finish that looks as good as it tastes.
How to Serve Chocolate Stout Cake with Whiskey Buttercream Frosting Recipe

Garnishes
To take your cake presentation to the next level, consider garnishing with chocolate shavings or curls, which bring an inviting texture and a classic look. A light dusting of cocoa powder on top or a few toasted walnuts also adds a beautiful rustic touch and a nice contrast of flavors and textures to complement the cake’s moist richness and creamy frosting.
Side Dishes
This cake pairs wonderfully with a scoop of vanilla bean ice cream or a dollop of freshly whipped cream. For a more grown-up serving, try accompanying it with a glass of your favorite stout or a small pour of whiskey to echo the cake’s flavors and enhance the tasting experience.
Creative Ways to Present
Serve your cake sliced on a rustic wooden board for a cozy vibe, or on a sleek white plate for a classy dinner party. Individual mini cakes or cupcakes made following this chocolate stout formula could be elegantly topped with a swirl of whiskey buttercream and a small edible gold leaf for a touch of sparkle that’s perfect for celebrations.
Make Ahead and Storage
Storing Leftovers
Once frosted, this cake will keep well stored in an airtight container at room temperature for up to two days, or refrigerated for up to five days. Keeping it covered is key to maintaining the moistness of the cake layers and the creamy texture of the buttercream.
Freezing
If you want to save part of this delectable creation, store unfrosted or fully frosted layers in an airtight container or wrapped tightly in plastic wrap and aluminum foil. Frozen, the cake will stay fresh for up to three months. Thaw overnight in the fridge before serving for the best texture.
Reheating
This cake is best enjoyed at room temperature, so if refrigerated, remove it from the fridge about 30 minutes prior to serving. Gently warming a slice in the microwave for 10-15 seconds can revive the luscious texture and let the whiskey buttercream soften just enough to enhance every bite.
FAQs
Can I use a different type of beer instead of stout for this cake?
Yes, you can try other dark beers like porter or a robust ale, but stout is preferred for its deep, chocolatey, and slightly bitter notes that enhance the cocoa flavor perfectly.
Is it necessary to use whiskey in the frosting?
The whiskey adds a unique warmth and complexity to the buttercream, but you can substitute with a teaspoon of vanilla extract or omit the alcohol entirely if you prefer a non-alcoholic version.
Can I make this cake gluten-free?
You can experiment with gluten-free flour blends that are designed for baking. Look for one that includes xanthan gum for better structure, but keep in mind the texture might vary slightly from the classic recipe.
How do I know when the cake layers are fully baked?
Use the toothpick test: insert a toothpick into the center of the cake, and if it comes out clean or with just a few moist crumbs, the cake is done baking.
What is the best way to level cake layers?
A cake leveler is a handy tool that helps you slice off the domed top evenly. Alternatively, you can carefully use a serrated knife by eye or with a ruler for consistent thickness, which makes stacking easier and your cake look polished.

Instructions
- Preheat Oven: Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius) to ensure it reaches the correct temperature for even baking.
