Ingredients

  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 1 1/2 teaspoons baking powder
  • 1 1/2 teaspoons baking soda
  • 1 teaspoon salt
  • 2 large eggs
  • 1 cup whole milk
  • 1/2 cup vegetable oil
  • 2 teaspoons vanilla extract
  • 1 cup boiling water
  • 1 cup unsalted butter, softened
  • 3 cups powdered sugar
  • 1/2 cup unsweetened cocoa powder
  • 1/2 cup heavy cream
  • 1 teaspoon vanilla extract
  • Pinch of salt

Directions

  1. Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan.
  2. In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  3. Add the eggs, milk, vegetable oil, and vanilla extract to the dry ingredients. Mix until well combined.
  4. Gradually add the boiling water to the batter, mixing continuously. The batter will be thin, but that's normal.
  5. Pour the batter into the prepared baking pan and smooth the top with a spatula.
  6. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
  7. While the cake is cooling, prepare the frosting. In a large bowl, beat the softened butter until creamy.
  8. Add the powdered sugar, cocoa powder, heavy cream, vanilla extract, and a pinch of salt to the bowl. Beat until smooth and well combined.
  9. Once the cake has completely cooled, spread the frosting evenly over the top.
  10. Slice and serve the dark chocolate sheet cake, and enjoy!
