- ¾ cup unsweetened cocoa powder
- 2 cups granulated sugar
- 2 tsp baking powder
- 1 ½ tsp baking soda
- 1 tsp salt
- ½ cup vegetable oil
- 2 large eggs
- 1 cup buttermilk
- 1 cup hot water or hot coffee
- 2 tsp vanilla extract
- For the Chocolate Buttercream
- 1 cup unsalted butter, softened
- 3 ½ cups powdered sugar
- ½ cup unsweetened cocoa powder

- ½ cup heavy cream
Instructions
- Make the Cake
- Preheat oven to 350°F (180°C). Grease and line two or three 8-inch cake pans.
- In a large bowl, whisk flour, cocoa powder, sugar, baking powder, baking soda, and salt.
- Add oil, eggs, buttermilk, and vanilla. Mix until combined.
- Pour in hot water or coffee and mix until smooth. Batter will be thin—this is perfect.
- Divide evenly into pans and bake 25–30 minutes or until a toothpick comes out clean.
- Let the cakes cool completely before frosting.
- Make the Buttercream
- Beat butter until creamy and pale.
- Add powdered sugar, cocoa powder, cream, vanilla, and salt. Beat until fluffy and smooth.
- Adjust consistency with more cream if needed.
- Assemble the Cake
- Level cake layers if needed.
- Add buttercream between each layer and frost the outside of the cake. Smooth the sides using an offset spatula.
- Chill the cake for 20–30 minutes to set the frosting before adding the drip.
- Make the Ganache Drip
- Heat cream until steaming. Pour over chocolate chips. Let sit 2 minutes, then stir until glossy.
- Let ganache cool slightly—should be pourable but not too runny.
- Use a spoon or squeeze bottle to drip ganache around the edges of the chilled cake.
- Fill the top with remaining ganache and smooth gently.
- Decorate
- Add swirls of buttercream, chocolate pieces, sprinkles, or berries on top if desired.
Notes
- Coffee enhances chocolate flavor but won’t make the cake taste like coffee.
- Cool ganache too much and it won’t drip; too warm and it will run down completely.
- Chill the frosted cake before dripping for perfect drip control.
- Cake layers can be made 1–2 days ahead.
