Why This Chocolate Cake Works
This recipe combines butter for flavor, oil for moisture, and boiling water to bloom the cocoa powder—creating an ultra-rich chocolate taste. The result is a tender cake that stays moist for days and pairs perfectly with creamy chocolate frosting.
Ingredients
For the Chocolate Cake
- 1¾ cups all-purpose flour
- ¾ cup unsweetened cocoa powder
- 1½ teaspoons baking powder
- 1½ teaspoons baking soda
- 1½ teaspoons salt
- 1 cup granulated sugar
- ¾ cup light brown sugar, packed
- ½ cup unsalted butter, room temperature
- ½ cup vegetable oil
- 2 large eggs
- 2 egg yolks
- 1 cup buttermilk
- 2 teaspoons vanilla extract
- 1 cup boiling water
For the Chocolate Frosting
- 6 oz semisweet chocolate, chopped
- ½ cup unsalted butter, room temperature
- 1½ cups powdered sugar
- ¼ cup heavy cream
- 1 teaspoon vanilla extract
Instructions
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans and set aside.
In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
In a large bowl, cream the butter with both sugars until light and fluffy. Beat in the eggs and egg yolks one at a time, then mix in the vanilla extract.
Add the dry ingredients and buttermilk alternately to the batter, beginning and ending with the dry ingredients. Mix just until combined.
Slowly stir in the boiling water until the batter is smooth and thin.
Divide the batter evenly between the prepared pans and bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
Cool the cakes in the pans for 10 minutes, then turn out onto a wire rack to cool completely.
To prepare the frosting, melt the chocolate and butter together over a double boiler, stirring until smooth. Let cool slightly, then beat in powdered sugar, heavy cream, and vanilla until creamy and spreadable.
Frost the cooled cake layers and decorate as desired.
Tips for the Best Chocolate Cake

- Add espresso powder (½ teaspoon) for extra richness
Storage
Store covered at room temperature for up to 2 days or refrigerate for up to 5 days. This cake also freezes beautifully.
