Ingredients

Cake Ingredients

  • 2 cups all-purpose flour
  • 2 cups sugar
  • 1/2 teaspoon salt
  • 1 teaspoon baking soda
  • 1 cup unsweetened cocoa powder
  • 1 cup buttermilk
  • 1 cup vegetable oil
  • 4 large eggs
  • 2 teaspoons vanilla extract
  • 1 cup boiling water

Frosting Ingredients

  • 1/2 cup unsalted butter
  • 1/4 cup milk
  • 3 1/2 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1/2 cup chopped nuts (optional)

Instructions 

Preparation

  • Preheat your oven to 350°F (175°C). Grease and flour a large sheet pan.
  • In a large bowl, combine flour, sugar, salt, baking soda, and cocoa powder. Whisk well so the cocoa dissolves into the dry mix.
  • In another bowl, mix together buttermilk, vegetable oil, eggs, and vanilla. Whisk until smooth.
  • Gradually add wet ingredients to dry ingredients, mixing until just combined. Do not overmix.
  • Stir in boiling water until the batter is smooth. The batter will be thin.

Baking

  • Pour the batter into the prepared pan and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.

Frosting

  • While the cake is baking, prepare the frosting by melting butter in a saucepan. Stir in cocoa powder and milk, bring to a boil.
  • Remove from heat and add powdered sugar and vanilla, whisking until smooth.
  • Once the cake has cooled slightly, pour the frosting over the cake and sprinkle with chopped nuts if desired.

Cooling and Serving

  • Allow the cake to cool before serving, letting the frosting firm a bit.
  • Serve family-style and pair with vanilla ice cream, whipped cream, or fresh berries.

Notes

You can use boxed cake mix for a quicker version. If you don’t have buttermilk, use a mixture of milk and vinegar. Nuts are optional and can be substituted with mini chocolate chips.
