Ingredients
For the Cake:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1 cup unsalted butter
- 1 cup water
- 1/4 cup unsweetened cocoa powder
- 1/2 cup buttermilk
- 2 large eggs
- 1 teaspoon baking soda
- 1 teaspoon vanilla extract
- 1/2 teaspoon salt
For the Fudgy Frosting:
- 1/2 cup unsalted butter
- 1/4 cup unsweetened cocoa powder
- 1/3 cup milk
- 4 cups powdered sugar
- 1 teaspoon vanilla extract
- 1/4 teaspoon salt
Step-by-Step Instructions
Step 1: Prepare the Cake Batter
Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan. In a large bowl, whisk together flour, sugar, baking soda, and salt. Set aside.
Step 2: Create the Chocolate Base
In a medium saucepan, combine butter, water, and cocoa powder. Bring to a boil, stirring constantly. Remove from heat and pour this warm chocolate mixture into the dry ingredients. Mix until just combined.
Step 3: Add Wet Ingredients
Add buttermilk, eggs, and vanilla extract to the batter. Mix until smooth and well-combined, but be careful not to overmix. The batter will be thin – this is normal!
Step 4: Bake the Cake
Pour the batter into your prepared pan and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. While the cake bakes, prepare the frosting.
Step 5: Make the Fudgy Frosting
In a medium saucepan, combine butter, cocoa powder, and milk. Heat over medium heat until butter melts and mixture is smooth. Remove from heat and whisk in powdered sugar, vanilla, and salt until the frosting is glossy and pourable.
Step 6: Frost While Warm
Pour the warm frosting over the warm cake immediately after removing from oven. Spread evenly with a spatula. Let the cake cool completely before slicing and serving.
Expert Tips for Perfect Chocolate Sheet Cake
- Room Temperature Ingredients: Ensure eggs and buttermilk are at room temperature for better emulsion
- Don’t Overmix: Mix just until ingredients are combined to avoid a tough cake
- Frost While Warm: The warm frosting soaks into the cake, creating extra moisture
- Use Good Cocoa: High-quality cocoa powder makes a significant difference in flavor
- Storage: Store covered at room temperature for up to 3 days
Frequently Asked Questions
Can I make this cake ahead of time?
Absolutely! Bake the cake up to 24 hours in advance, then frost just before serving. The cake stays incredibly moist.
Can I use vegetable oil instead of butter?
Yes, you can substitute equal parts vegetable oil for butter in the cake batter. The texture will be slightly different but still delicious.
What size pan should I use?
A standard 9×13 inch baking pan is perfect. Don’t use a smaller pan as the cake may overflow.
How do I know when the cake is done?
The cake is ready when a toothpick inserted in the center comes out clean, and the edges pull away slightly from the pan.
