Ingredients

• 1 cup unsalted butter
• 1 cup water
• 0.25 cup unsweetened cocoa powder
• 2 cups granulated sugar
• 2 cups all-purpose flour
• 1 teaspoon baking soda
• 0.5 teaspoon salt
• 0.5 cup sour cream
• 2 pieces large eggs
• 0.5 cup unsalted butter (for frosting)
• 0.25 cup unsweetened cocoa powder (for frosting)
• 0.33 cup whole milk
• 3.5 cups powdered sugar
• 1 teaspoon vanilla extract
• 0.5 cup chopped pecans (optional, for frosting)

Directions

Step 1

Preheat the oven to 350°F (175°C). Grease and flour a 13x18-inch sheet pan (or line it with parchment paper).

Step 2

In a medium saucepan, melt 1 cup of unsalted butter over medium heat. Add 1 cup of water and 1/4 cup of unsweetened cocoa powder, whisking until smooth. Remove from heat and set aside to cool slightly.

Step 3

In a large mixing bowl, combine 2 cups of granulated sugar, 2 cups of all-purpose flour, 1 teaspoon of baking soda, and 0.5 teaspoon of salt.

Step 4

Pour the cocoa mixture into the dry ingredients and mix until combined.

Step 5

In a small bowl, whisk together 0.5 cup of sour cream and 2 large eggs. Add this to the batter and mix just until smooth.

Step 6

Pour the batter into the prepared sheet pan and spread it evenly. Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.

Step 7

While the cake is baking, prepare the frosting. In a medium saucepan, melt 0.5 cup of unsalted butter over medium heat. Stir in 0.25 cup of unsweetened cocoa powder and 0.33 cup of whole milk. Bring to a gentle boil, then remove from heat.

Step 8

Whisk in 3.5 cups of powdered sugar and 1 teaspoon of vanilla extract until smooth. Stir in 0.5 cup of chopped pecans, if using.

Step 9

Once the cake is out of the oven, immediately pour the warm frosting over the hot cake. Spread it evenly with a spatula, working quickly as the frosting will set as it cools.

Step 10

Allow the cake to cool completely before slicing and serving. Enjoy!
