Equipment

  • Mixing Bowls
  • Electric Mixer
  • Cake Pans

Ingredients
  

Cake Batter

  • 1 3/4 cups all-purpose flour
  • 3/4 cup unsweetened cocoa powder
  • 2 cups granulated sugar
  • 1 1/2 tsp baking powder
  • 1 1/2 tsp baking soda
  • 1 tsp salt
  • 2 eggs room temperature
  • 1 cup buttermilk room temperature
  • 1/2 cup vegetable oil
  • 2 tsp vanilla extract
  • 1 cup boiling water

Instructions
 

  • Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  • In a large mixing bowl, whisk together the flour, cocoa powder, sugar, baking powder, baking soda, and salt.
  • Add eggs, buttermilk, vegetable oil, and vanilla extract. Beat on medium speed until smooth.
  • Reduce speed to low and carefully add the boiling water. The batter will be thin—this is normal.
  • Divide the batter evenly between the prepared cake pans.
  • Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
  • Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.

Notes

For extra decadence, frost with chocolate ganache or buttercream frosting!
