Ultimate Chocolate Layer Cake
Ingredients:
For the cake:
2 cups all-purpose flour
2 cups granulated sugar
3/4 cup cocoa powder
2 tsp baking powder
1 1/2 tsp baking soda
1 tsp salt
1 cup buttermilk
1/2 cup vegetable oil
2 large eggs
2 tsp vanilla extract
1 cup boiling water
For the frosting:
1 cup unsalted butter, softened
3 1/2 cups powdered sugar
1 cup cocoa powder
1/2 cup heavy cream
2 tsp vanilla extract
Instructions:
1. Preheat oven to 350°F (175°C). Grease and line three 9-inch round cake pans.
2. In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.
3. Add buttermilk, vegetable oil, eggs, and vanilla. Mix until smooth. Stir in boiling water (batter will be thin).
4. Divide the batter evenly among the prepared pans and bake for 30-35 minutes. Cool completely.
5. For the frosting, beat butter until creamy. Gradually add powdered sugar and cocoa powder. Mix in heavy cream and vanilla until smooth.
6. Assemble the cake by layering frosting between each layer and covering the outside. Smooth and decorate as desired.
Step-by-Step Guide
Follow these detailed instructions for a perfect cake. First, ensure all ingredients are at room temperature, especially the eggs and buttermilk, for even mixing. When adding the boiling water in step 3, pour it in a slow, steady stream while mixing on low speed; the batter will be very liquid, which is correct and creates a moist crumb. For baking, use an oven thermometer to verify the 350°F temperature. Rotate the pans halfway through baking for even browning. Cool cakes in their pans for 15 minutes before turning them out onto a wire rack to cool completely. Wrap layers in plastic wrap and chill for 1 hour before frosting for easier handling.
Serving Suggestions
This rich cake pairs beautifully with fresh berries like raspberries or strawberries, which cut through the chocolate intensity. For a dessert presentation, add a dollop of lightly sweetened whipped cream or a scoop of vanilla bean ice cream alongside each slice. Garnish with chocolate shavings, a dusting of powdered sugar, or a drizzle of salted caramel sauce for extra decadence. Serve with coffee, espresso, or a glass of cold milk.
How-to Summary
To summarize: Whisk dry ingredients, mix in wet ingredients except boiling water, then carefully incorporate boiling water for a thin batter. Bake three layers at 350°F for 30-35 minutes. Cool completely. For frosting, cream butter, then alternate adding dry ingredients with cream and vanilla. Frost cooled cake layers and exterior.
Frequently Asked Questions
Can I make buttermilk if I don’t have any?
Yes. Add 1 tablespoon of lemon juice or white vinegar to 1 cup of regular milk. Let it sit for 5-10 minutes until slightly curdled before using.
Why is boiling water added to the batter?
The hot water “blooms” the cocoa powder, intensifying its chocolate flavor. It also helps create a smooth, thin batter that results in an exceptionally moist cake.
Can I bake this in a different pan size?
For two 9-inch pans, increase baking time to 35-40 minutes. For a 9×13 sheet cake, bake for 35-40 minutes. Always check for doneness with a toothpick.
How should I store the finished cake?
Store covered at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days. Let slices come to room temperature before serving for the best texture and flavor.
My frosting is too thick or too thin. How can I fix it?
If too thick, add more heavy cream, one teaspoon at a time. If too thin, add more powdered sugar, a quarter cup at a time, until the desired spreading consistency is reached.
Common Mistakes to Avoid
- Overmixing the batter: Mix only until ingredients are combined after adding the wet ingredients. Overmixing develops gluten, leading to a tough, dense cake.
- Using cold ingredients: Cold eggs and buttermilk can cause the batter to seize and result in uneven baking. Always bring them to room temperature.
- Frosting a warm cake: The frosting will melt and slide off. Ensure all layers are completely cool, and chilling them is highly recommended.
- Measuring flour incorrectly: Do not scoop directly from the bag. Spoon flour into the measuring cup and level it off to avoid a dry, crumbly cake.
Conclusion
This ultimate chocolate layer cake is a showstopping dessert that balances deep chocolate flavor with a tender, moist crumb. By following the detailed steps, avoiding common pitfalls, and using the serving suggestions, you can create a professional-quality cake at home.
