Ingredients
For the Cake:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup unsalted butter
- 1 cup water
- 1/2 cup high-quality cocoa powder
- 2 large eggs
- 1/2 cup buttermilk
- 2 teaspoons vanilla extract
For the Frosting:
- 1/2 cup unsalted butter
- 1/4 cup cocoa powder
- 1/3 cup milk
- 4 cups powdered sugar
- 1 teaspoon vanilla extract
- 1/2 cup chopped walnuts or pecans (optional)
Step-by-Step Instructions
Prepare the Cake Batter
Preheat your oven to 350°F (175°C). Grease a 13×9-inch baking pan and set aside. In a large mixing bowl, whisk together flour, sugar, baking soda, and salt.
In a medium saucepan, combine butter, water, and cocoa powder. Heat over medium heat until the butter melts and the mixture comes to a gentle boil. Pour the hot cocoa mixture over the dry ingredients and stir until well combined.
Add Wet Ingredients
In a separate bowl, whisk together eggs, buttermilk, and vanilla extract. Add this mixture to the chocolate batter and stir until smooth and well incorporated. The batter will be thin – this is normal for sheet cakes.
Bake the Cake
Pour the batter into the prepared pan and spread evenly. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. While the cake bakes, prepare the frosting.
Dark Chocolate Frosting
In a medium saucepan, combine butter, cocoa powder, and milk. Heat over medium heat until the butter melts and the mixture is smooth. Remove from heat and whisk in powdered sugar and vanilla extract until the frosting is glossy and pourable.
Pour the warm frosting over the hot cake immediately after removing it from the oven. Spread evenly with an offset spatula and sprinkle with chopped nuts if desired. This rich chocolate frosting technique creates a beautiful glossy finish.
Expert Tips for Success
- Use High-Quality Cocoa: Since this cake relies on cocoa for its flavor, choose a premium Dutch-process cocoa powder for the deepest chocolate taste.
- Don’t Overbake: Sheet cakes continue to cook slightly after removal from the oven, so remove when the edges pull away from the pan.
- Frost While Warm: Applying the frosting to a warm cake allows it to soak in slightly, creating a moist texture throughout.
- Cool Completely: Allow the cake to cool completely before cutting for clean slices.
This cake pairs wonderfully with fresh fruit desserts for a balanced dessert table.
Frequently Asked Questions
Can I make this cake ahead of time?
Yes, this cake actually tastes better the next day as the flavors meld together. Store covered at room temperature.
Can I use natural cocoa instead of Dutch-process?
You can use natural cocoa, but the flavor will be less intense. Dutch-process cocoa provides the deep, rich chocolate flavor that makes this cake special.
How should I store leftovers?
Cover the cake tightly with plastic wrap or store in an airtight container at room temperature for up to 3 days.
Can I freeze this cake?
Yes, you can freeze the unfrosted cake for up to 3 months. Thaw completely before frosting.
What makes this cake “grown-up” compared to other chocolate cakes?
The reduced sugar content and emphasis on intense cocoa flavor rather than sweetness makes this dessert more sophisticated and less cloying than traditional chocolate cakes.
