Ingredients You’ll Need

2 cups all-purpose flour: Essential for structure; make sure to spoon and level for accuracy.
¾ cup natural unsweetened cocoa powder: Provides rich chocolate flavor; avoid Dutch process for the best results.
2 teaspoons baking soda: Helps the cake rise and creates a light texture.
1 teaspoon instant espresso powder (optional): Intensifies the chocolate flavor without making it taste like coffee.
1 teaspoon salt: Enhances the overall taste.
1 cup granulated sugar: Adds sweetness and moisture.
1 cup packed light brown sugar: Contributes to the cake’s rich flavor and tenderness.
½ cup canola or vegetable oil: Keeps the cake moist; other neutral oils can work as substitutes.
½ cup buttermilk: Adds tanginess and softness to the cake; sour cream is a good alternative.
½ cup full-fat sour cream: Provides moisture and richness; can use Greek yogurt as a substitute.
2 large eggs: Binds ingredients together and helps with structure.
2 teaspoons pure vanilla extract: Adds depth of flavor.
1 cup Guinness beer: The star ingredient; this stout brings moistness and a unique, rich flavor; non-alcoholic beer can also be used.
1 ½ cups unsalted butter (softened): Creates a creamy frosting base; make sure it’s softened for easy mixing.
4 ½ cups powdered sugar: Sweetens and adds fluffiness to the frosting.
4 to 5 tablespoons Baileys Irish Cream: Adds a delicious, creamy flavor; can adjust for lighter taste by mixing with heavy cream.
1 ½ teaspoons pure vanilla extract: Flavors the frosting; keep it pure for the best taste.
⅛ teaspoon salt: Balances the sweetness of the frosting.

How to Make Guinness Chocolate Cake

Preheat the Oven: Begin by preheating your oven to 350°F (177°C). Prepare two 9-inch round cake pans by spraying with nonstick cooking spray and lining the bottoms with parchment paper. This will ensure easy removal after baking.
Combine Dry Ingredients: In a large mixing bowl, sift together 2 cups all-purpose flour, ¾ cup natural unsweetened cocoa powder, 2 teaspoons baking soda, 1 teaspoon instant espresso powder (if using), and 1 teaspoon salt. Whisk in 1 cup granulated sugar and 1 cup packed light brown sugar until mixed well.
Incorporate Wet Ingredients: Add ½ cup canola oil, ½ cup buttermilk, ½ cup full-fat sour cream, 2 large eggs, and 2 teaspoons pure vanilla extract to the dry mixture. Mix until well combined. Gradually stir in 1 cup of Guinness beer, mixing until everything is just combined—the batter should be smooth and glossy.
Bake the Cakes: Divide the batter evenly between the two prepared cake pans. Bake in the preheated oven for 25 to 30 minutes or until a toothpick inserted into the center comes out clean. The cakes should rise nicely and have a beautiful dome.
Cool the Cakes: Once baked, remove the cakes from the oven and allow them to cool in the pans for about 20 to 30 minutes. Run a knife around the edges and carefully remove them from the pans, placing them on a wire rack to cool completely. For easier frosting, wrap the cooled layers in plastic wrap and refrigerate until ready to use. Alternatively, pop them in the freezer for quick firming.
Make Baileys Buttercream Frosting: In the bowl of a stand mixer fitted with the paddle attachment, beat 1 ½ cups unsalted butter on medium speed until smooth. Gradually mix in 4 ½ cups powdered sugar, one cup at a time, on low speed, ensuring it’s blended well after each addition. Add 4 to 5 tablespoons of Baileys Irish Cream, 1 ½ teaspoons pure vanilla extract, and ⅛ teaspoon salt, mixing on low until everything is combined. Scrape the sides of the bowl as needed.
Assemble the Cake: Level the tops of both cooled cake layers using a knife. Place a tablespoon of frosting on a cardboard cake round to help secure the cake. Lay the first layer of cake on your serving surface. Spread 1 cup of frosting on top, smoothing it evenly with an angled spatula.
Stack the Layers: Place the second cake layer upside down on top to ensure a flat surface on top, maintaining balance and height. Apply a thin coat of frosting over the entire cake to catch any crumbs, making it easier for the final frosting layer. Chill until the crumb coat is firm.
Frost the Cake: Once the crumb coat is set, use the remaining frosting to cover the top and sides of the cake. If you want to pipe decorations, reserve some frosting for later.
Decorate: Transfer your frosting into a piping bag fitted with a piping tip and decorate the top edge of the cake if desired. Slice and serve, relishing every bite of this exquisite dessert.

Storing & Reheating

Store your Guinness Chocolate Cake at room temperature in an airtight container for up to 2 days. If you have leftovers, refrigerate them for up to 4 days. For longer storage, wrap the cake tightly in plastic wrap and freeze for up to 3 months. When ready to enjoy, let it thaw in the fridge or at room temperature. Reheat individual slices in the microwave for about 15-20 seconds for a cozy treat, but keep in mind the frosting may soften slightly after freezing.

Chef’s Helpful Tips

Remember to always measure your flour properly to avoid a dense cake—spoon it into your measuring cup and level it off.
Room temperature ingredients blend better, so let your butter and eggs warm up for about 30 minutes before starting.
Don’t rush the cooling phase; chilled cake layers are easier to frost without crumbling.
If your cake domes up while baking, gently press the top down after it comes out of the oven for a perfect flat surface.
Experiment with different types of beer; while Guinness is classic, try different stouts for varied flavors.

There you have it—a rich, moist Guinness Chocolate Cake that’ll surely impress your family and friends. The combination of deep chocolate and beer will tantalize your taste buds, and let’s not forget that luscious Baileys frosting! Don’t be afraid to tweak the recipe to suit your preferences. You might even want to try adding a hint of salted caramel or dark chocolate shavings for extra indulgence. Enjoy every bite of this delightful creation, and happy baking!
