Ingredients

• 2 cups all-purpose flour
• 2 cups granulated sugar
• 0.5 teaspoons salt
• 1 cup unsalted butter
• 1 cup water
• 4 tablespoons unsweetened cocoa powder
• 0.5 cups buttermilk
• 2 pieces large eggs
• 1 teaspoon vanilla extract
• 1 teaspoon baking soda
• 0.5 cups unsalted butter (for frosting)
• 3 tablespoons unsweetened cocoa powder (for frosting)
• 6 tablespoons whole milk
• 1 teaspoon vanilla extract (for frosting)
• 3.5 cups powdered sugar
• 1 cup chopped pecans (optional)

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease and flour a 9x13-inch sheet pan or line it with parchment paper.

Step 2

In a large mixing bowl, sift together the all-purpose flour, granulated sugar, and salt. Set aside.

Step 3

In a medium saucepan, combine 1 cup unsalted butter, 1 cup water, and 4 tablespoons cocoa powder. Heat over medium heat until the butter melts and the mixture is smooth. Bring it just to a boil and then immediately remove it from heat.

Step 4

Pour the hot cocoa mixture into the dry ingredients and stir until well combined.

Step 5

In another bowl, whisk together the buttermilk, eggs, vanilla extract, and baking soda. Add this mixture to the batter and stir until smooth.

Step 6

Pour the batter into the prepared sheet pan and spread evenly. Bake in the preheated oven for 20-22 minutes or until a toothpick inserted in the center comes out clean.

Step 7

While the cake is baking, prepare the frosting. In a medium saucepan, melt 1/2 cup butter over medium heat. Stir in 3 tablespoons cocoa powder and 6 tablespoons of milk. Heat until the mixture is smooth and just comes to a simmer. Remove from heat.

Step 8

Stir in the vanilla extract and powdered sugar. Mix until the frosting is smooth and lump-free. If desired, fold in the chopped pecans.

Step 9

Once the cake is out of the oven, pour the frosting over the hot cake and spread it evenly. Allow the cake to cool completely before slicing and serving.
