Nutrition Table (Per Slice, Based on 12 Slices)

Main Ingredients (For 1 Layered 9-inch Cake, 12 Servings)

• 300 g (2 ½ cups) all-purpose flour
• 40 g (½ cup) black cocoa powder
• 300 g (1 ½ cups) granulated sugar
• 120 ml (½ cup) vegetable oil
• 2 large eggs
• 240 ml (1 cup) buttermilk
• 1 tsp vanilla extract
• 1 tsp baking soda
• 1 tsp baking powder
• ½ tsp salt
• 1 tsp white vinegar
• 150 g (1 cup) fresh blackberries, pureed
• Optional: 1–2 drops black food coloring for extra dramatic color

For the Blackberry Buttercream:

• 250 g (1 cup) unsalted butter, softened
• 500 g (4 cups) powdered sugar
• 80 g (⅓ cup) blackberry puree (strained to remove seeds)
• 1 tsp vanilla extract
• 1–2 tbsp heavy cream (as needed for texture)

Ingredient Breakdown and Roles

Flour – 300 g (2 ½ cups)

Flour provides the structure of the cake, forming the base for gluten development. All-purpose flour strikes a balance between strength and tenderness. It ensures the cake has enough body to hold layers and frosting without being overly dense.

Black Cocoa Powder – 40 g (½ cup)

Black cocoa is the ingredient that gives this cake its gothic, midnight appearance. Unlike regular cocoa powder, black cocoa is ultra-dark and smooth, creating a deep chocolate flavor with less acidity. It is key for both the color and the rich, mysterious flavor.

Granulated Sugar – 300 g (1 ½ cups)

Sugar sweetens the cake but also contributes to moisture by trapping liquid in the batter. It caramelizes during baking, enhancing depth of flavor and balancing the tartness of the blackberry puree.

Vegetable Oil – 120 ml (½ cup)

Oil keeps the cake moist for days, even when refrigerated. It creates a soft crumb that feels luxurious without heaviness. Unlike butter, oil doesn’t solidify when cold, ensuring consistent texture.

Eggs – 2 large

Eggs act as binders and help trap air during mixing, creating lift. The yolks also add richness, while the whites contribute structure. Together, they balance the cake’s density and fluffiness.

Buttermilk – 240 ml (1 cup)

Buttermilk provides acidity, which reacts with baking soda for a light, tender crumb. It also imparts subtle tanginess that complements the sweetness of sugar and the richness of cocoa.

Vanilla Extract – 1 tsp

Vanilla adds warmth and enhances the cake’s overall flavor profile. Though subtle, it rounds out the chocolate and fruit notes beautifully.

Baking Soda & Baking Powder – 1 tsp each

These leavening agents ensure proper rise. Baking soda reacts with the buttermilk and vinegar, while baking powder gives extra lift, preventing the cake from being heavy.

Salt – ½ tsp

Salt enhances all the flavors and balances sweetness. Without it, the cake would taste flat.

Vinegar – 1 tsp

Vinegar works with baking soda to create a light texture. It’s a classic ingredient in velvet cakes, ensuring the crumb is tender and not overly dense.

Blackberry Puree – 150 g (1 cup)

Fresh blackberry puree adds fruitiness, natural sweetness, and a touch of acidity. It deepens the cake’s gothic appeal by creating subtle purple undertones. The puree also keeps the cake moist.

Black Food Coloring – optional

While the black cocoa already provides deep color, food coloring can intensify the effect for a true gothic cake presentation. It is not necessary but useful if aiming for dramatic impact.

Blackberry Buttercream Ingredients

Butter – 250 g (1 cup)

Unsalted butter is the foundation of buttercream, giving it structure and richness. It should be softened but not melted to ensure a fluffy, stable frosting.

Powdered Sugar – 500 g (4 cups)

This provides sweetness and body. Its fine texture ensures a smooth, non-gritty frosting that spreads and pipes easily.

Blackberry Puree – 80 g (⅓ cup)

Strained blackberry puree infuses the buttercream with vibrant flavor and natural color. It also adds moisture, making the frosting creamy and flavorful.

Vanilla Extract – 1 tsp

Vanilla enhances the fruit flavor, ensuring the buttercream is balanced rather than overly tart.

Heavy Cream – 1–2 tbsp

Cream lightens the frosting and adjusts texture. It makes the buttercream spreadable without losing structure.

How to Prepare Blackberry Velvet Gothic Cake

Step 1: Prepare the Blackberry Puree

Rinse fresh blackberries and blend until smooth. Strain through a fine sieve to remove seeds. Divide into two portions: one for the cake batter and one for the buttercream.

Step 2: Mix Dry Ingredients

In a large bowl, whisk together flour, black cocoa, baking powder, baking soda, salt, and sugar. This ensures even distribution of leaveners and prevents clumps of cocoa.

Step 3: Mix Wet Ingredients

In a separate bowl, whisk together eggs, oil, buttermilk, vinegar, vanilla, and the first portion of blackberry puree. Blend until smooth and consistent.

Step 4: Combine Batter

Slowly add the wet mixture into the dry ingredients, whisking gently until smooth. Avoid over-mixing, which can toughen the cake. The batter should be thick but pourable, with a deep, dark color.

Step 5: Bake the Cake

Preheat oven to 175°C (350°F). Grease and line two 9-inch round cake pans. Divide batter evenly and bake for 28–32 minutes, or until a toothpick inserted in the center comes out clean. Cool cakes completely on a wire rack.

Step 6: Make the Buttercream

Beat softened butter until fluffy. Gradually add powdered sugar, mixing on low to avoid spillage. Add blackberry puree and vanilla, beating until creamy. If frosting is too thick, add cream one tablespoon at a time.

Step 7: Assemble the Cake

Level cooled cakes if necessary. Place one layer on a serving plate, spread buttercream evenly, then add the second layer. Frost the outside with remaining buttercream. Decorate with whole blackberries, edible flowers, or gothic-themed toppers.

Variations of Blackberry Velvet Gothic Cake

1. Gothic Black Forest Cake

This variation takes inspiration from the classic Black Forest cake but gives it a gothic twist. Instead of cherries, blackberries are used as the fruit element, paired with layers of whipped cream or buttercream. Dark cocoa remains central, and shaved dark chocolate adds texture.

The result is a cake that is both traditional and daring. The blackberry-black cocoa combination creates a moody, luxurious aesthetic while maintaining the familiar Black Forest structure. Perfect for gothic-themed parties or dramatic occasions.

2. Blackberry Gothic Cupcakes

Transform the recipe into cupcakes for individual servings. The batter can be portioned into a muffin tin, baked for 18–20 minutes, and topped with blackberry buttercream swirls. Cupcakes allow for more creative decorations, from gothic sprinkles to edible glitter.

This variation is ideal for events where slicing a cake may be inconvenient. Cupcakes are portable, customizable, and just as visually impactful as the full cake. They are especially popular for Halloween parties or gothic weddings.

3. Vegan Blackberry Velvet Gothic Cake

For a plant-based version, replace eggs with flaxseed gel (1 tbsp flaxseed meal + 3 tbsp water per egg), use plant-based milk with vinegar for buttermilk, and substitute vegan butter in the frosting. Black cocoa and blackberries remain the stars of the show.

The vegan version is just as moist and flavorful as the original. It ensures everyone, regardless of diet, can enjoy this gothic masterpiece. This adaptation proves that elegance and inclusivity can coexist beautifully in baking.

4. Blackberry Chocolate Drip Cake

Enhance the gothic appeal by adding a dark chocolate ganache drip over the frosted cake. Prepare a simple ganache with equal parts cream and chocolate, pour along edges, and let it drip naturally. The glossy finish adds dramatic flair.

This version pairs beautifully with the tartness of blackberry buttercream. The combination of matte black cocoa layers, purple frosting, and glossy chocolate drips creates a cake that is both delicious and visually arresting.

Troubleshooting Tips

• Cake too dry? Measure flour carefully and avoid overbaking. Oil and blackberry puree should keep it moist.
• Buttercream too runny? Add more powdered sugar or chill for 10 minutes to firm.
• Cake not rising evenly? Ensure baking soda and powder are fresh and properly measured.
• Color not dramatic enough? Use a drop of black food coloring to enhance the gothic look.

Storage and Serving Suggestions

This cake can be stored at room temperature (covered) for up to 2 days or refrigerated for up to 5 days. For longer storage, wrap slices in plastic and freeze for up to 2 months. To serve, allow refrigerated cake to come to room temperature for best texture.

Serve slices with fresh blackberries or dark chocolate shavings. For a complete gothic presentation, pair with black plates, candlelight, and dramatic décor. This cake is a centerpiece in both flavor and appearance.
