Ingredients

For the Cake:

• 2 cups all-purpose flour
• 2 cups granulated sugar
• 1 teaspoon baking soda
• ¼ teaspoon salt
• 1 cup butter
• 1 cup water
• ¼ cup unsweetened cocoa powder
• 2 large eggs
• ½ cup buttermilk
• 1 teaspoon vanilla extract

For the Fudgy Icing:

• ½ cup butter
• ¼ cup whole milk
• ¼ cup unsweetened cocoa powder
• 3½ cups powdered sugar
• 1 teaspoon vanilla extract
• ½ cup chopped pecans (optional)

Step-by-Step Instructions

Step 1: Preheat your oven to 350°F (175°C). Grease a 15×10-inch jelly roll pan or similar sized baking sheet.

Step 2: In a large mixing bowl, whisk together flour, sugar, baking soda, and salt. Set aside.

Step 3: In a medium saucepan, combine butter, water, and cocoa powder. Heat over medium heat until butter melts and mixture comes to a boil, stirring constantly.

Step 4: Pour the hot cocoa mixture over the dry ingredients and stir until well combined.

Step 5: In a small bowl, whisk together eggs, buttermilk, and vanilla extract. Add to the batter and mix until smooth.

Step 6: Pour batter into the prepared pan and spread evenly. Bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.

Step 7: While the cake bakes, prepare the icing. In a saucepan, combine butter, milk, and cocoa powder. Bring to a boil, then remove from heat.

Step 8: Whisk in powdered sugar and vanilla until smooth. Stir in pecans if using.

Step 9: As soon as the cake comes out of the oven, pour the warm icing over the hot cake and spread evenly.

Step 10: Allow the cake to cool completely before cutting into squares and serving.

Expert Tips

Perfect Texture: Don’t overmix the batter – just stir until ingredients are combined. Overmixing can make the cake tough.

Buttermilk Substitute: If you don’t have buttermilk, mix ½ cup milk with 1½ teaspoons lemon juice or vinegar and let it sit for 5 minutes.

Timing is Key: Spread the icing on the cake while both are warm. This creates that signature fudgy texture as the icing soaks slightly into the warm cake.

Storage: Store covered at room temperature for up to 3 days. The cake actually gets more moist and flavorful the next day!
