Ingredients

Scale
  • 2 cups (240g) all-purpose flour
  • 2 cups (400g) granulated sugar
  • 3/4 cup (75g) unsweetened cocoa powder
  • 1 1/2 teaspoons baking soda
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon salt
  • 1 cup (240ml) buttermilk, room temperature
  • 1/2 cup (120ml) vegetable oil
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 1 cup (240ml) hot brewed coffee
  • 1/2 cup (113g) unsalted butter, softened (for frosting)
  • 2/3 cup (65g) unsweetened cocoa powder (for frosting)
  • 3 cups (360g) powdered sugar, sifted (for frosting)
  • 1/3 cup (80ml) milk or cream (for frosting)
  • 1 teaspoon vanilla extract (for frosting)
  • Pinch of salt (for frosting)

Instructions

  1. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan with butter or non-stick spray.
  2. In a large bowl, sift together the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
  3. In a separate bowl, whisk together the buttermilk, vegetable oil, eggs, and vanilla extract until fully blended.
  4. Pour the wet mixture into the dry ingredients and stir gently with a spatula until just combined; a few lumps are okay.
  5. Add the hot brewed coffee to the batter and mix gently until smooth. The batter will be thin.
  6. Pour the batter evenly into the prepared pan and tap lightly on the counter to release air bubbles.
  7. Bake for 35-40 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs but no raw batter.
  8. Let the cake cool completely in the pan on a cooling rack for at least 1 hour before frosting.
  9. To prepare the frosting, beat the softened butter until creamy. Add cocoa powder and mix until combined.
  10. Gradually add powdered sugar alternated with milk or cream until smooth and spreadable.
  11. Stir in vanilla extract and a pinch of salt.
  12. Spread the frosting evenly over the cooled cake. Optionally, sprinkle chocolate shavings or colorful sprinkles on top.

Notes

Let the cake cool completely before frosting to prevent melting. Use hot coffee to enhance chocolate flavor without bitterness. Avoid overmixing to keep cake tender and moist. If frosting is too thick, add more milk; if too thin, add more powdered sugar. Chill frosting briefly before spreading if kitchen is warm.
