Ingredients

For the Cake:

2 cups all-purpose flour
2 cups granulated sugar
1 cup unsalted butter
1 cup water
⅓ cup cocoa powder
1 teaspoon baking soda
½ teaspoon salt
2 large eggs
½ cup buttermilk
1 teaspoon vanilla extract

For the Fudgy Chocolate Icing:

½ cup unsalted butter
⅓ cup whole milk
¼ cup cocoa powder
3 cups powdered sugar
1 teaspoon vanilla extract
½ cup chopped pecans (optional)

Step-by-Step Instructions

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan and set aside.

Step 1: Combine Dry Ingredients

In a large mixing bowl, whisk together flour, sugar, baking soda, and salt until well combined. This one-bowl method ensures minimal cleanup and even distribution of ingredients.

Step 2: Create Chocolate Base

In a saucepan over medium heat, combine butter, water, and cocoa powder. Heat until the butter is melted and the mixture is smooth, stirring frequently. Pour this warm chocolate mixture over the dry ingredients and stir until just combined.

Step 3: Add Wet Ingredients

In a small bowl, whisk together eggs, buttermilk, and vanilla extract. Add this mixture to the chocolate batter and stir until smooth. The batter will be thin – this is normal and results in a moist cake.

Step 4: Bake to Perfection

Pour the batter into the prepared pan and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. The cake will be springy to the touch.

Step 5: Prepare the Icing

While the cake is baking, make the fudgy chocolate icing. In a medium saucepan, combine butter, milk, and cocoa powder. Heat until the butter is melted and the mixture is smooth. Remove from heat and whisk in powdered sugar and vanilla until glossy and pourable.

Step 6: Ice While Warm

Pour the warm icing over the warm cake as soon as it comes out of the oven. If using pecans, sprinkle them over the icing immediately. This allows the icing to soak slightly into the cake for maximum moisture.

Expert Tips for Perfect Results

Temperature Matters: Use room temperature ingredients for the best texture. Cold ingredients can affect how the cake rises.

Don’t Overmix: Mix the batter just until combined – overmixing can lead to a dense cake.

Timing is Key: Ice the cake while both the cake and icing are warm for that signature fudgy texture that makes this dessert so irresistible.

Storage: This chocolate sheet cake stays moist for days when stored covered at room temperature. It’s the perfect make-ahead dessert for busy weeks.
