- 1 cup hot water (240g)
- 2 tsp instant espresso or coffee (5g)
- 1 cup buttermilk, room temperature (240g)
- 1/2 cup vegetable or canola oil (110g)
- 2 large eggs, room temperature (112g)
- 2 tsp vanilla extract or vanilla bean paste (8g)
Frosting Ingredients
- 2 cups (4 sticks) unsalted butter, room temperature (454g)
- 1 cup black cocoa powder (100g)
- 1 tsp vanilla extract or vanilla bean paste (4g)
- 1/2 tsp fine salt (3g)

- 2/3 cup heavy whipping cream, room temperature (180g)
- 1 1/3 cups dark chocolate chips, melted and cooled (230g)
Instructions
- Preheat and Prepare Pans: Preheat your oven to 350°F (175°C). Grease and line three 8-inch cake pans or four 7-inch pans to prevent sticking and ensure easy removal.
- Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, granulated sugar, black cocoa powder, baking powder, baking soda, and salt until well combined.
- Dissolve Espresso in Hot Water: In a medium bowl, stir the instant espresso or coffee into the hot water until fully dissolved to enhance the chocolate flavor.
- Combine Wet Ingredients: Add the buttermilk, vegetable oil, eggs, and vanilla extract to the espresso mixture. Stir briefly until smooth and uniform.
- Mix Wet into Dry Ingredients: Pour the wet ingredients into the dry ingredients and mix gently by hand until fully incorporated. The batter will be thin, which is intended for a tender crumb.
- Divide Batter and Bake: Evenly divide the batter among the prepared pans, using a kitchen scale to ensure equal amounts. Bake for 24 to 27 minutes, or until a toothpick inserted in the center comes out clean.
- Cool Cake Layers: Remove cakes from the oven and let them cool in the pans for 10 minutes. Then loosen the edges with a spatula and invert onto wire racks to cool completely.
- Level Cake Layers: Once cooled, use a serrated knife to level the tops of the cakes for even stacking. Freeze layers if preparing ahead of time.
- Make Buttercream Frosting: Beat the unsalted butter on medium speed for 30 seconds until smooth. Add black cocoa powder, vanilla extract, and salt, mixing on low speed until combined.
- Incorporate Powdered Sugar and Cream: Gradually add powdered sugar, mixing continuously. Halfway through, add heavy cream to ease mixing and achieve a smooth frosting texture.
- Add Melted Dark Chocolate: Slowly mix in the melted and cooled dark chocolate on low speed, ensuring it is liquid but not hot. Continue mixing until frosting is fully combined and smooth.
- Optional Coloring: For a deeper black color, add black gel food coloring if desired. Cover the frosting with plastic wrap to prevent crusting until ready to use.
- Assemble Cake: Place the first cake layer on a greaseproof cake board secured with a small dab of frosting. Spread an even layer of buttercream on top, then stack the remaining layers.
- Crumb Coat and Chill: Apply a thin crumb coat of frosting to the entire cake and smooth with a bench scraper. Chill in the refrigerator for 30 minutes or in the freezer for 10 minutes to firm up.
- Final Frosting Layer and Decorate: Apply a second thicker layer of frosting, smooth again with a bench scraper, decorate as desired, and serve this rich, moist Black Velvet Cake.
Notes
- Using instant espresso or coffee enhances the chocolate flavor without making the cake taste like coffee.
- Make sure all ingredients are at room temperature for the best texture and mixing results.
- The batter will be thin; this is normal for a tender crumb and moist cake layers.
- Leveling the cake layers ensures an even, professional-looking cake assembly.
- Chilling the crumb coat helps achieve a smooth final frosting layer and reduces crumbs mixing with the frosting.
- Black gel food coloring is optional but can intensify the cake’s dramatic black color.
- Store the cake covered in the refrigerator and bring to room temperature before serving for the best flavor.
