Step-by-Step Instructions
Part 1: Baking the Chocolate Cake Layers
- Preheat Oven & Prepare Pans: Preheat your oven to 350°F (175°C). Grease and flour three 8-inch round cake pans. For best results, also line the bottoms with parchment paper circles.
- Combine Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt.
- Add Wet Ingredients (Except Coffee): Add the large eggs, buttermilk, vegetable oil, and vanilla extract to the dry ingredients. Mix on medium speed with an electric mixer until just combined and smooth, scraping down the sides of the bowl as needed.
- Add Hot Coffee: Carefully pour in the hot coffee (or hot water). Mix on low speed until the batter is completely smooth and liquidy. The batter will be quite thin, which is normal for a moist chocolate cake.
- Fill and Bake: Divide the batter evenly among the three prepared 8-inch cake pans. You can use a kitchen scale for precise distribution.
- Bake: Bake for 25-30 minutes, or until a wooden skewer or toothpick inserted into the center of a cake comes out clean.
- Cool Cakes: Remove the pans from the oven and let the cakes cool in the pans on a wire rack for 10-15 minutes. Then, carefully invert the cakes onto the wire rack, remove the parchment paper, and let them cool completely to room temperature before frosting. Warm cakes will melt the frosting.
Part 2: Preparing the Silky Vanilla Buttercream
- Cream Butter: In a large mixing bowl with an electric mixer (stand mixer or handheld), beat the softened unsalted butter on medium speed for 2-3 minutes until creamy and light.
- Add Powdered Sugar: Gradually add the sifted powdered sugar, about 1 cup at a time, beating on low speed until incorporated after each addition. Once all the sugar is added, increase the speed to medium-high.
- Add Cream and Vanilla: Pour in the heavy cream, vanilla extract, and a pinch of salt. Beat on medium-high speed for another 3-5 minutes, until the buttercream is light, fluffy, and smooth. If the frosting is too thick, add a teaspoon more cream; if too thin, add a tablespoon more powdered sugar.
Part 3: Making the Glossy Chocolate Ganache Drip
- Heat Cream: Place the semi-sweet chocolate chips in a heatproof bowl. In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer around the edges (do not boil).
- Pour Over Chocolate: Pour the hot cream directly over the chocolate chips. Let it sit undisturbed for 5 minutes.
- Stir Ganache: After 5 minutes, gently whisk the mixture from the center outwards until it is completely smooth and glossy.
- Cool Ganache: Let the ganache cool slightly at room temperature for 15-30 minutes, stirring occasionally, until it reaches a consistency suitable for dripping – it should be pourable but thick enough to create defined drips.
Part 4: Assembling and Decorating the Cake
- Level Cakes (Optional): If your cake layers have domed tops, use a serrated knife to carefully level them, creating flat surfaces for easier stacking.
- First Layer: Place one cooled cake layer on your serving plate or cake stand. Spread about 1 cup of vanilla buttercream evenly over the top.
- Second Layer: Carefully place the second cake layer on top, pressing down gently. Spread another 1 cup of vanilla buttercream evenly.
- Final Layer: Place the third cake layer on top, pressing gently to secure.
- Crumb Coat: Apply a thin layer of buttercream all over the top and sides of the entire cake. This is called a crumb coat and traps any loose crumbs. Refrigerate the cake for 15-20 minutes to allow the crumb coat to set.
- Final Frosting: Once the crumb coat is firm, apply the remaining buttercream to the top and sides of the cake, using an offset spatula or bench scraper to create a smooth finish.
- Apply Ganache Drip: Once the final buttercream layer is set (a quick chill in the fridge helps), carefully pour the slightly cooled ganache over the center of the cake. Gently push some of the ganache towards the edges, letting it drip artfully down the sides. You can use a spoon to guide some drips.
- Decorate: While the ganache is still wet, if desired, pipe remaining buttercream into swirls on top of the cake. Place chocolate truffles, chocolate-covered nuts, or chocolate shavings. Finish with fresh mint leaves for a pop of color.
- Chill Before Serving: Refrigerate the finished cake for at least 30 minutes to allow the ganache to set and the cake to firm up slightly for cleaner slicing.
Tips, Variations, and Storage
- Cocoa Powder: Dutch-processed cocoa powder gives a darker color and mellower chocolate flavor compared to natural cocoa. Both work, but results will vary slightly.
- Hot Coffee: The hot coffee enhances the chocolate flavor without making the cake taste like coffee. It also helps thin the batter to the right consistency.
- Ganache Consistency: If your ganache is too thick for dripping, gently warm it over a double boiler or in the microwave in 5-second bursts until it’s the right consistency. If too thin, let it cool longer.
- Buttercream Consistency: For piping, you might want a slightly stiffer buttercream. Add a tablespoon more powdered sugar if needed.
- Flavor Boosts: A teaspoon of espresso powder can be added to the cake batter to deepen the chocolate flavor. A splash of liquor (like Kahlua or Grand Marnier) can be added to the ganache for an adult twist.
- Storage: Store the chocolate layer cake, covered, at room temperature for up to 2 days, or in the refrigerator for up to 4-5 days. Allow refrigerated cake to come to room temperature for at least 30 minutes before serving for the best texture and flavor.
Pairings
- Beverages: Serve with a rich cup of coffee, a glass of cold milk, or a dessert wine like a Ruby Port or a sweet Red Zinfandel.
- Fruit: A side of fresh raspberries or strawberries can cut through the richness beautifully.
