Ingredients
For the Cake
- 1 3/4 cups all-purpose flour
- 1 cup black cocoa powder
- 2 cups granulated sugar
- 2 teaspoons baking soda
- 1 teaspoon baking powder
- 1 teaspoon salt
- 2 large eggs
- 1 cup buttermilk
- 1/2 cup vegetable oil
- 1 teaspoon vanilla extract
- 1 cup hot coffee or hot water
For the Chocolate Ganache
- 1 cup semi-sweet chocolate chips
- 3/4 cup heavy cream
For the Whipped Topping
- 1 cup heavy whipping cream
- 2 tablespoons powdered sugar
- 1 teaspoon vanilla extract
Instructions
Preheat your oven to 350°F and grease a 9-inch round cake pan. Line the bottom with parchment paper to help the cake release cleanly after baking.
In a large mixing bowl, whisk together the flour, black cocoa powder, sugar, baking soda, baking powder, and salt until fully combined. Black cocoa powder gives the cake its dramatic dark appearance and smooth chocolate flavor.
Add the eggs, buttermilk, vegetable oil, and vanilla extract to the dry ingredients. Mix until the batter becomes smooth and thick.
Slowly pour in the hot coffee while stirring gently. The batter will become thinner, which is completely normal and helps create a moist, tender cake texture.
Pour the batter into the prepared cake pan and smooth the top evenly.
Bake for 35 to 40 minutes or until a toothpick inserted into the center comes out with a few moist crumbs attached. Avoid overbaking because black cocoa cakes can dry out if left too long in the oven.
Allow the cake to cool in the pan for 15 minutes before transferring it to a wire rack to cool completely.
To make the ganache, heat the heavy cream until steaming but not boiling. Pour it over the chocolate chips and let sit for one minute. Stir until smooth, glossy, and fully melted.
Pour the ganache over the cooled cake, allowing it to drip slightly down the sides for a rich bakery-style finish.
For the whipped topping, beat the heavy cream, powdered sugar, and vanilla until soft peaks form. Spoon or pipe the whipped cream onto the cake before serving.
Finish with chocolate shavings or a light dusting of cocoa powder if desired.

FAQs
What is black cocoa powder?
Black cocoa powder is an ultra-dark Dutch-processed cocoa powder with a smooth, less bitter flavor. It is commonly used in sandwich cookies and gives desserts a deep black color and intense chocolate appearance.
Can I substitute regular cocoa powder?
You can, but the cake will not have the same dark color or signature flavor. Black cocoa powder creates a unique rich taste that regular cocoa powder cannot fully replicate.
Does the cake taste like coffee?
No, the coffee simply enhances the chocolate flavor and makes it richer. If you prefer, you can use hot water instead, but coffee gives the cake deeper flavor.
Can I make this cake ahead of time?
Yes, this cake actually tastes even better the next day because the flavors continue developing as it rests. Store it covered in the refrigerator and bring slices to room temperature before serving.
Why is my cake so dark?
That dramatic dark color comes from the black cocoa powder. It creates the bold black appearance while keeping the cake soft, moist, and rich.
