Ingredients:

  • For the Cake:
    • 2 cups all-purpose flour  
    • 2 cups granulated sugar  
    • 1 teaspoon baking soda
    • 1/2 teaspoon salt
    • 1/2 cup unsweetened cocoa powder  
    • 1 cup (2 sticks) unsalted butter, softened
    • 1 cup water
    • 2 large eggs
    • 1/2 cup buttermilk
    • 1 teaspoon vanilla extract  
  • For the Frosting:
    • 1 cup (2 sticks) unsalted butter
    • 1/2 cup unsweetened cocoa powder
    • 1/4 cup milk
    • 4 cups powdered sugar
    • 1 teaspoon vanilla extract
  • For the Topping:
    • 2 cups pecan halves

Instructions:

  1. Prepare the Cake:
    • Preheat oven to 350°F (175°C). Grease and flour a 13×9 inch baking pan.  
    • In a large bowl, whisk together the flour, sugar, baking soda, salt, and cocoa powder.
    • In a saucepan, melt the butter over medium heat. Add the water and bring to a simmer.
    • Pour the hot butter mixture into the dry ingredients and mix until well combined.
    • Add the eggs, buttermilk, and vanilla extract. Beat until smooth.
    • Pour the batter into the prepared baking pan.
    • Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.  
    • Let the cake cool completely.
  2. Prepare the Frosting:
    • In a saucepan, melt the butter over medium heat.
    • Add the cocoa powder and milk, and whisk until smooth.
    • Remove from heat and gradually add the powdered sugar, whisking until smooth and creamy.
    • Stir in the vanilla extract.
  3. Frost the Cake:
    • Pour the warm frosting over the cooled cake and spread evenly.
  4. Add Pecan Topping:
    • Arrange the pecan halves evenly over the frosting.
  5. Serve:
    • Let the frosting set for a few minutes before slicing and serving.

Tips and Notes:

  • Buttermilk: Buttermilk adds moisture and tanginess to the cake. If you don’t have buttermilk, you can make your own by adding 1 tablespoon of lemon juice or vinegar to 1 cup of milk.  
  • Frosting Consistency: Adjust the amount of powdered sugar to achieve your desired frosting consistency.
  • Pecan Variations: You can use chopped pecans instead of pecan halves for the topping.  
  • Make Ahead: You can make the cake ahead of time and store it in the refrigerator for up to 3 days.
  • Storage: Store leftover cake in an airtight container at room temperature for up to 3 days.
