Ingredients

Units Scale

For the Cake:

  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 1/2 teaspoon salt
  • 1 cup (2 sticks) unsalted butter
  • 1/4 cup unsweetened cocoa powder
  • 1 cup boiling water
  • 1/2 cup buttermilk
  • 2 large eggs, beaten
  • 1 teaspoon vanilla extract
  • 1 teaspoon baking soda

For the Frosting:

  • 3/4 cup (1 1/2 sticks) unsalted butter
  • 1/4 cup unsweetened cocoa powder
  • 1/2 cup milk
  • 1 teaspoon vanilla extract
  • 3 cups powdered sugar
  • 1 cup chopped pecans

Instructions

  1. Preheat Oven
    Preheat your oven to 350°F and prepare a half-sheet pan (13×18 inches) by greasing it with nonstick spray. This ensures that your cake doesn’t stick when it’s baked and removed.
  2. Mix Dry Ingredients
    In a large mixing bowl, combine flour, sugar, and salt. Set this mixture aside in preparation for the wet ingredients.
  3. Prepare Cocoa Mixture
    In a saucepan over medium heat, melt the butter. Once melted, whisk in the cocoa powder until evenly combined. Stir in the boiling water and increase the heat slightly to bring it to a soft boil. Let it boil for 30 seconds before removing it immediately from heat.
  4. Combine Wet and Dry
    Pour the hot cocoa mixture over the dry ingredients and stir well to ensure the mixture is fully incorporated. Scrape the bottom and sides of the bowl as you mix.
  5. Add Remaining Wet Ingredients
    In a separate medium bowl, whisk together the buttermilk, eggs, vanilla extract, and baking soda. Gradually mix this buttermilk mixture into the chocolate and flour mixture. Stir until fully combined.
  6. Bake the Cake
    Pour the batter into the prepared baking sheet and spread it out evenly. Bake in the preheated oven for 15-20 minutes, or until the top springs back lightly and the edges begin pulling away from the sides of the pan.
  7. Prepare the Frosting
    While the cake bakes, melt the butter in a saucepan over low heat. Stir in the cocoa powder, milk, vanilla extract, and powdered sugar. Whisk until the frosting is smooth and fully combined. Remove the saucepan from heat and stir in the chopped pecans.
  8. Frost the Cake
    Once the cake is removed from the oven, immediately pour the frosting over the warm cake. Use an offset spatula to spread the frosting evenly to the edges of the cake.
  9. Cool and Serve
    Allow the cake to cool completely so the frosting can set. Slice into squares and serve. Enjoy the rich chocolate flavor with every bite!

Notes

  • Allow the frosting to soak slightly into the warm cake for ultimate flavor and texture.
  • Toast the pecans lightly before adding them to the frosting for a deeper nutty flavor.
  • You can substitute buttermilk with a mixture of milk and lemon juice or vinegar (1 tablespoon lemon juice/vinegar for every 1 cup milk) if you’re out of buttermilk.
  • This cake freezes well! Slice into squares and freeze in an airtight container for up to 3 months.
