Ingredients

Scale
  • For the Black Velvet Cake:
    • 2 ½ cups all-purpose flour
    • 2 ½ tsp baking powder
    • 1 ½ tsp baking soda
    • 1 tsp salt
    • ½ cup unsweetened cocoa powder
    • 1 ½ cups granulated sugar
    • 1 cup vegetable oil
    • 2 large eggs
    • 1 tsp vanilla extract
    • 1 cup buttermilk
    • 1 tbsp white vinegar
    • 2 tsp black food coloring (or as needed)
  • For the Blackberry Filling:
    • 2 cups fresh or frozen blackberries
    • 1 cup granulated sugar
    • 1 tbsp lemon juice
    • 1 tbsp cornstarch
    • 2 tbsp water
  • For the Chocolate Frosting:
    • 1 cup unsalted butter, softened
    • 3 cups powdered sugar
    • ½ cup unsweetened cocoa powder
    • 1 tsp vanilla extract
    • ¼ cup heavy cream
    • Pinch of salt

Instructions

  1. For the Black Velvet Cake:
    1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
    2. In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cocoa powder. Set aside.
    3. In a large bowl, whisk together the sugar, vegetable oil, eggs, and vanilla extract until smooth and combined.
    4. Add the buttermilk and vinegar, and mix until incorporated.
    5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Add the black food coloring, stirring until the batter is a deep black color.
    6. Divide the batter evenly between the two prepared cake pans and smooth the tops with a spatula.
    7. Bake for 30–35 minutes, or until a toothpick inserted into the center of the cakes comes out clean. Let the cakes cool in the pans for 10 minutes, then remove from the pans and cool completely on a wire rack.
  2. For the Blackberry Filling:
    1. In a medium saucepan, combine the blackberries, sugar, lemon juice, cornstarch, and water.
    2. Cook over medium heat, stirring constantly, until the mixture thickens and the berries break down, about 5-7 minutes.
    3. Remove from heat and let the blackberry filling cool completely before using it in the cake.
  3. For the Chocolate Frosting:
    1. In a large mixing bowl, beat the softened butter on medium speed until smooth and creamy.
    2. Gradually add the powdered sugar and cocoa powder, beating until smooth and well combined.
    3. Add the vanilla extract, heavy cream, and a pinch of salt, and beat on high speed for 2–3 minutes until the frosting is fluffy and smooth. Adjust the consistency by adding more cream if needed.
  4. Assembling the Cake:
    1. Place one layer of the cooled black velvet cake on a serving plate or cake stand. Spread a layer of blackberry filling over the top, then top with the second layer of cake.
    2. Frost the top and sides of the cake with the chocolate frosting. Garnish with fresh blackberries if desired.
    3. Let the cake set for about 30 minutes to allow the frosting to firm up before slicing and serving.

Notes

  • For a smoother frosting, sift the powdered sugar and cocoa powder before mixing.
  • Ensure the blackberry filling is fully cooled before adding it to the cake to prevent it from melting the frosting.
  • This cake is rich, so it’s perfect for special occasions like birthdays or holidays.
  • If you don’t have black food coloring, you can use dark brown or navy blue food coloring, though the color may vary slightly.
  • Store any leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for longer storage.
