Ingredients
For the Black Velvet Cake
- 2 ½ cups (300g) all-purpose flour
- 2 cups (400g) granulated sugar
- 1 cup (85g) black cocoa powder (Dutch-processed)
- 2 tsp baking powder
- 1 ½ tsp baking soda
- 1 tsp fine sea salt
- 3 large eggs, room temperature
- 1 cup (240ml) vegetable oil
- 1 cup (240ml) buttermilk, room temperature
- 1 cup (240ml) hot coffee or hot water
- 2 tsp pure vanilla extract
- 1 tbsp white vinegar
For the Black Cocoa Buttercream
- 1 ½ cups (340g) unsalted butter, room temperature
- 4 cups (480g) powdered sugar
- 1 cup (85g) black cocoa powder
- ¼ cup (60ml) heavy cream
- 2 tsp vanilla extract
- Black gel food coloring, optional
- Pinch of salt
Optional Decoration
- Edible gold leaf or gold dust mixed with clear alcohol or lemon extract
- Offset spatula or food-safe paintbrush
Instructions
- Prepare the Cake Pans: Preheat the oven to 350°F (175°C). Grease three 8-inch round cake pans and line the bottoms with parchment paper to ensure the cakes release cleanly after baking.
- Mix the Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, black cocoa powder, baking powder, baking soda, and fine sea salt until well combined.
- Whisk the Wet Ingredients: In a separate bowl, whisk the eggs, vegetable oil, buttermilk, pure vanilla extract, and white vinegar until the mixture is smooth and homogenous.
- Combine Wet and Dry: Pour the wet mixture into the dry ingredients and stir gently just until no dry streaks remain, being careful not to overmix to maintain a tender crumb.
- Add Hot Coffee: Slowly pour the hot coffee or hot water into the batter, whisking gently until the batter is fully combined and smooth. The batter will be thin in consistency.
- Bake the Cakes: Divide the batter evenly among the prepared cake pans. Bake for 28 to 32 minutes or until a toothpick inserted in the center comes out clean with a few moist crumbs.
- Cool the Layers: Let the cakes cool in their pans for 10 minutes. Then carefully turn them out onto wire racks to cool completely before frosting.
- Make the Buttercream: Using a stand mixer fitted with a paddle attachment, beat the unsalted butter on medium speed for 2 to 3 minutes until light and creamy.
- Add Sugar and Cocoa: Gradually sift in the powdered sugar and black cocoa powder while mixing on low speed to avoid a powdered sugar cloud. Add a pinch of salt to balance the flavors.
- Finish the Frosting: Pour in the heavy cream and vanilla extract. Increase mixer speed to medium-high and beat for 3 to 5 minutes until the buttercream is fluffy and spreadable. Add black gel food coloring if a deeper black color is desired.
- Level and Stack: Once cake layers are completely cool, level tops if needed using a serrated knife. Place the first layer on a cake board or serving plate, spread an even layer of buttercream on top, then repeat with remaining layers.
- Frost the Cake: Apply a thin crumb coat of buttercream around the sides and top of the cake, then chill for 15 to 20 minutes to set the crumb coat. Apply a final smooth layer of black cocoa buttercream to cover the entire cake completely.
- Apply Gold Decoration: After the frosting is firm to the touch, use a clean offset spatula or food-safe paintbrush to apply edible gold leaf or gold dust mixed with clear alcohol or lemon extract in streaks or splatters to give an elegant finishing touch.
Notes
- Ensure eggs and buttermilk are at room temperature for better batter emulsification.
- Use Dutch-processed black cocoa powder for the best rich color and flavor.
- Hot coffee enhances the chocolate flavor but can be substituted with hot water if desired.
- To achieve the richest black color, add black gel food coloring gradually and adjust to preference.
- Chilling the crumb coat helps to create a smoother final finish on the cake.
- Be careful when handling edible gold leaf as it is very delicate and thin.
- This cake is best stored covered at room temperature for up to 3 days or refrigerated for up to 5 days.
