Cake Ingredients
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup (2 sticks) unsalted butter
- 1 cup water
- 1/4 cup unsweetened cocoa powder
- 2 large eggs
- 1/2 cup buttermilk
- 1 teaspoon vanilla extract
Fudgy Icing Ingredients
- 1/2 cup (1 stick) unsalted butter
- 1/4 cup unsweetened cocoa powder
- 6 tablespoons milk
- 1 teaspoon vanilla extract
- 3 1/2 cups powdered sugar
- 1 cup chopped pecans or walnuts (optional)
Step-by-Step Instructions
Prepare the Cake Batter
Preheat your oven to 350°F (175°C). Grease and flour a 10×15-inch jelly roll pan or a 9×13-inch baking pan.
In a large mixing bowl, whisk together the flour, sugar, baking soda, and salt. Set aside.
In a medium saucepan, combine the butter, water, and cocoa powder. Heat over medium heat, stirring occasionally, until the butter melts and the mixture comes to a gentle boil. Remove from heat and pour the hot chocolate mixture over the dry ingredients. Stir until just combined.
In a small bowl, whisk together the eggs, buttermilk, and vanilla extract. Add this to the chocolate batter and mix until smooth and well combined.
Pour the batter into the prepared pan and bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
Make the Fudgy Icing
While the cake bakes, prepare the icing. In a medium saucepan, combine the butter, cocoa powder, and milk. Heat over medium heat until the butter melts and the mixture begins to boil. Remove from heat and stir in the vanilla extract.
Gradually whisk in the powdered sugar until smooth. If using nuts, stir them in at this point.
Assemble the Cake
As soon as the cake comes out of the oven, pour the warm icing over the hot cake, spreading it evenly with a spatula. The heat from the cake will help the icing set into a beautiful, glossy finish.
Allow the cake to cool completely before cutting into squares and serving. This resting time allows the flavors to meld and the icing to set perfectly.
Expert Tips for Perfect Sheet Cake
Measure accurately: For consistent results, use proper measuring techniques. Spoon flour into measuring cups and level with a knife rather than scooping directly from the container.
Don’t overmix: Once you combine the wet and dry ingredients, mix just until incorporated. Overmixing can lead to a tough cake texture.
Timing is everything: Make sure your icing is ready to pour as soon as the cake comes out of the oven. This hot-on-hot technique creates that signature glossy finish that makes this cake so special.
Customize your add-ins: While pecans are traditional, you can substitute walnuts, shredded coconut, or even sprinkle with mini chocolate chips for different flavor variations.

Frequently Asked Questions
Can I make this cake ahead of time?
Absolutely! This cake actually tastes better the next day as the flavors have time to develop. Store it covered at room temperature for up to 3 days.
Can I freeze chocolate sheet cake?
Yes, this cake freezes beautifully. Cut it into individual portions, wrap tightly in plastic wrap, and freeze for up to 3 months. Thaw at room temperature before serving.
What can I use instead of buttermilk?
If you don’t have buttermilk, make your own by adding 1 1/2 teaspoons of vinegar or lemon juice to 1/2 cup of milk. Let it sit for 5 minutes until slightly thickened.
Why is my icing grainy?
Grainy icing usually means the powdered sugar wasn’t fully dissolved. Make sure your butter-cocoa mixture is hot enough and whisk vigorously while adding the powdered sugar.
