Ingredients

  • For the cake:
  • 2 cups all-purpose flour, plus more, to taste, for dusting the pan
  • 2 cups granulated sugar
  • 1/2 cup unsweetened cocoa powder
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 2 large eggs
  • 1 cup vegetable oil
  • 1 cup whole buttermilk, shaken
  • 1 cup water, hot
  • For the chocolate buttermilk icing:
  • 1 stick salted butter
  • 2/3 cup unsweetened cocoa powder
  • 3 cups confectioners' sugar, sifted
  • 1/3 cup whole buttermilk, shaken, plus more, to taste
  • 1 teaspoon vanilla extract

Directions

Step 1 -Preheat the oven to 350 degrees F.

Step 2 -Grease a 9x13-inch baking dish, then using the extra flour, lightly dust it. Optionally, line it with parchment paper.

Step 3 -In a large bowl, add the remaining 2 cups of the flour, the granulated sugar, 1/2 cup of the cocoa powder, the baking soda, the baking powder, and the salt and whisk to combine.

Step 4 -Add the eggs, the vegetable oil, and 1 cup of the buttermilk to the dry ingredients mixture and whisk well to combine.

Step 5 -Add the hot water to the batter mixture and whisk until smooth.

Step 6 -Evenly add the batter to the prepared baking dish and gently tap the baking dish on a flat surface to release any air bubbles.

Step 7 -Bake until a toothpick inserted into the center comes out clean, about 30-35 minutes.

Step 8 -Transfer the baked cake from the oven to a wire rack and let it cool completely before frosting.

Step 9 -While the cake is cooling, in a medium saucepan over medium-low heat, melt the butter.

Step 10 -Decrease the stovetop heat to low.

Step 11 -Add the remaining cocoa powder to the melted butter and cook, while whisking, until combined and the cocoa is very fragrant, about 2 minutes. Do not let the mixture boil.

Step 12 -Transfer the cocoa-butter mixture from the stovetop to a wire rack.

Step 13 -Add the confectioners' sugar and 1/3 cup of the remaining buttermilk to the cocoa mixture and whisk until smooth.

Step 14 -Add the vanilla extract to the icing mixture and whisk to combine.

Step 15 -If the icing is too thick, add the extra buttermilk, 1 tablespoon at a time, and whisk to combine after each addition. The icing should be thick but easily spreadable.

Step 16 -Evenly spread the icing mixture on top of the cooled cake and let the icing mixture cool and set.

Step 17 -Cut the cake into serving-sized pieces and serve.
