  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon salt

  • 3/4 cup cocoa powder
  • 4 cups powdered sugar
  • 2 teaspoons vanilla
  • 1/4 cup heavy cream (plus more as needed)

Instruction

  • Preheat oven to 350 degrees F. Spray a 9x13-inch baking dish with cooking spray or line two 9-inch cake pans with parchment paper circles and spray sides with cooking spray.
  • Whisk flour, sugar, cocoa powder, baking soda, baking powder, and salt together in a large bowl.  
  • Add the buttermilk, oil, eggs, and vanilla and mix on medium speed using a hand mixer or stand mixer until combined.  
  • Add the hot water and mix on low speed until combined. Scrape bottom and sides of the bowl and mix on medium speed for 30 seconds.
  • Pour into the baking dish or divide evenly between cake pans. Bake for 32-37 minutes for a rectangular cake, or 30-35 minutes for 9-inch round cake pans until a toothpick inserted into the center of the cake comes out clean.  
  • Cool completely before frosting.
