Ingredients

Scale

For the Cake:

  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 2 teaspoons baking powder
  • 1 1/2 teaspoons baking soda
  • 1 teaspoon salt
  • 1 cup buttermilk (at room temperature)
  • 1/2 cup vegetable oil
  • 2 large eggs (at room temperature)
  • 2 teaspoons vanilla extract
  • 1 cup hot water

For the Frosting:

  • 1 cup unsalted butter (softened)
  • 3 1/2 cups powdered sugar
  • 1/2 cup unsweetened cocoa powder
  • 1/2 cup buttermilk (at room temperature)
  • 2 teaspoons vanilla extract
  • Pinch of salt

Instructions

  • Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  • In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  • Add the buttermilk, vegetable oil, eggs, and vanilla extract to the dry ingredients. Mix until combined.
  • Gradually add the hot water to the batter, mixing well until smooth. The batter will be thin, but that’s okay.
  • Pour the batter evenly into the prepared pans and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
  • Allow the cakes to cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
  • In a large bowl, beat the softened butter until creamy.
  • Gradually add the powdered sugar and cocoa powder, beating until well combined.
  • Add the buttermilk, vanilla extract, and salt. Beat until the frosting is smooth and fluffy.
  • Once the cakes are completely cooled, spread a layer of frosting on top of one cake layer. Place the second cake layer on top and frost the top and sides of the cake.

Notes

  • Storage: Keep the cake covered at room temperature for up to 3 days, or refrigerate for longer storage.
  • Frosting Tip: For an extra fluffy frosting, beat the mixture for an additional 2-3 minutes.
  • Optional Add-ins: Add chocolate chips to the batter for extra chocolatey goodness.
