Ingredients
For the Cake:
- 2 cups all-purpose flour
- 1½ cups granulated sugar
- ¾ cup unsweetened cocoa powder (dark/Dutch-processed)
- 2 teaspoons baking soda
- 1 teaspoon baking powder
- 1 teaspoon salt
- 2 large eggs
- 1 cup buttermilk
- ½ cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup boiling water
For the Dark Chocolate Frosting:
- ½ cup unsalted butter, softened
- ⅔ cup unsweetened cocoa powder
- 3 cups powdered sugar
- ½ cup milk
- 1 teaspoon vanilla extract
- Pinch of salt
Step-by-Step Instructions
Step 1: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan and line with parchment paper.
Step 2: In a large bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt until well combined.
Step 3: In a separate bowl, beat eggs, buttermilk, vegetable oil, and vanilla extract until smooth. Pour the wet ingredients into the dry ingredients and mix until just combined.
Step 4: Carefully stir in the boiling water until the batter is smooth. The batter will be thin – this is normal.
Step 5: Pour the batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
Step 6: While the cake cools, prepare the frosting. Beat butter until creamy, then add cocoa powder and mix until smooth. Gradually add powdered sugar, milk, vanilla, and salt, beating until light and fluffy.
Step 7: Spread the frosting over the cooled cake. Allow to set for at least 30 minutes before serving.

Don’t skip the boiling water step – it helps bloom the cocoa powder, enhancing the chocolate flavor and creating the moist crumb texture. For an even more sophisticated dessert, consider trying our Brick Street Chocolate Cake which offers another layer of chocolate indulgence.
