Preheat the Oven: Start by preheating your oven to 350°F (175°C). This ensures that the cake bakes evenly.
Prepare the Pans: Grease two 9-inch round cake pans and line the bottoms with parchment paper. This will help you remove the cakes easily later.
Sift the Dry Ingredients: In a large mixing bowl, sift together the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt. This will help to incorporate air and make your cake light and fluffy.
Mix the Wet Ingredients: Add the buttermilk, vegetable oil, eggs, and vanilla extract to the dry ingredients. Beat the mixture on medium speed until smooth.
Add Boiling Water: Gradually add the boiling water to the batter. Don't worry—it will be thin, and that's just right!
Bake the Cakes: Divide the batter evenly between the prepared pans. Bake in the preheated oven for 30-35 minutes or until a toothpick inserted into the center comes out clean.
Cool the Cakes: Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack. Let them cool completely before frosting.
Make the Ganache: For the frosting, heat the heavy cream in a small saucepan until it simmers. Remove it from the heat, pour over the chopped dark chocolate, and let sit for 2 minutes. Stir until smooth and mix in the butter until glossy. Let cool until spreadable.
Frost the Cake: Place one cake layer on a serving plate and spread a generous amount of ganache on top. Add the second layer and cover the cake with the remaining ganache.
Set the Frosting: Refrigerate the cake for at least 30 minutes to let the frosting set before serving.
What to Serve Decadent Dark Chocolate Layer Cake With
This cake can easily steal the show on its own, but serving it with a scoop of vanilla ice cream or a dollop of whipped cream elevates it to the next level! You might also consider pairing it with fresh fruit like raspberries or strawberries to provide a touch of tartness that balances the rich chocolate flavor.
Top Tips for Perfecting Decadent Dark Chocolate Layer Cake
Use Quality Ingredients: The flavor of your cake will greatly depend on the quality of the cocoa powder and chocolate you use. Opt for high-quality dark chocolate for the ganache for a richer taste.
Don’t Rush the Cooling: Let your cakes cool completely before frosting; otherwise, the ganache could melt, resulting in a mess!
Adjust for Altitude: If you live in a higher altitude area, you may need to adjust cooking times and ingredients. Follow local recommendations for baking adjustments.
Storing and Reheating Tips
If you have leftovers (which is rare with this cake!), store it in an airtight container in the fridge for up to 4 days. To freeze, wrap individual slices in plastic wrap followed by aluminum foil; it can stay fresh for up to 3 months. When you’re ready to enjoy, simply let it thaw at room temperature or warming it gently in the microwave.
