Ingredients

For the Cake Layers

• 2 cups (≈ 250 g) all‑purpose flour
• 1 ½ cups (≈ 300 g) granulated sugar
• ¾ cup (≈ 75 g) unsweetened cocoa powder
• 1½ teaspoons baking powder
• 1 teaspoon baking soda
• ½ teaspoon salt
• 3 large eggs, at room temperature
• 1 cup (≈ 240 ml) buttermilk, at room temperature
• ½ cup (≈ 120 ml) vegetable oil
• 2 teaspoons vanilla extract
• ½ cup (≈ 120 ml) hot water

For the Blackberry Filling

• 1½ to 2 cups fresh or frozen blackberries
• ¼‑⅓ cup granulated sugar
• 1 tablespoon lemon juice
• 2 tablespoons cornstarch mixed with 2 tablespoons water (slurry)

For the Frosting

• 8 oz (≈ 225 g) cream cheese, softened
• ½ cup (≈ 113 g) unsalted butter, softened
• 3 cups (≈ 360 g) powdered sugar
• 1 teaspoon vanilla extract
• Optional: ½ cup mashed blackberries (strained of seeds for smoothness)

For Garnish

• Fresh blackberries
• Dark chocolate shavings
• (Optional) Edible flowers or decorative accents

Instructions

1. Preheat the oven to 350 °F (≈ 175 °C). Grease and line two 9‑inch round cake pans with parchment paper.
2. Mix dry ingredients: In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda and salt until evenly distributed.
3. Combine wet ingredients: In another bowl, whisk eggs, buttermilk, oil and vanilla extract until smooth.
4. Combine wet + dry: Gradually pour the wet mixture into the dry ingredients, stirring until just combined. Then add hot water and stir until the batter is smooth.
5. Bake the layers: Divide the batter evenly between the prepared pans. Bake for 30‑35 minutes, or until a toothpick inserted into the centre comes out clean. Remove from oven and let cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
6. Make the blackberry filling: In a small saucepan over medium heat, combine the blackberries, sugar and lemon juice. Cook until the berries release their juices and become tender (~5‑7 minutes). Stir in the cornstarch slurry and cook for another 1‑2 minutes until thickened. Remove from heat and let cool completely.
7. Make the frosting: Using an electric mixer, beat the cream cheese and butter together until smooth and fluffy. Gradually add powdered sugar, then vanilla extract and mashed (seed‑strained) blackberries if using. Mix until well‑combined and smooth.
8. Assemble the cake: Place one cake layer on a serving plate. Spread a layer of blackberry filling over the top of the first layer. Place the second cake layer on top. Frost the top and sides of the cake with the blackberry‑cream‑cheese frosting.
9. Decorate: Garnish with fresh blackberries and dark chocolate shavings. Chill the cake for at least 30 minutes to set the filling and frosting before slicing.
10. Serve: Allow slices to come to near room temperature for best texture and flavour.

You Must Know

• Let the cake layers cool fully before applying filling or frosting—frosting on warm cake will melt and slide.
• Balance the filling and frosting flavour — too much blackberry filling can make the cake soggy; ensure it’s thickened and cooled before spreading.
• Don’t over‑bake the layers — testing with a toothpick around 28‑30 minutes helps avoid dryness.
• Room temperature ingredients for smooth batter — eggs, buttermilk and butter should be at room temperature for even mixing and better texture.
• Chill before slicing — after assembly, chilling helps the layers set and makes clean slicing easier.

Storage Tips

• Refrigerator: Store the assembled cake in a cake keeper or covered with plastic wrap for up to 3 days. Bring to room temperature about 30 minutes before serving for optimal texture.
• Freezer: You can freeze the unfrosted cake layers (wrapped tightly) for up to 2 months. Thaw overnight in the fridge, then frost and assemble when ready.
• Avoid sitting out: Because the filling and frosting contain dairy and fresh berries, keep the cake refrigerated when not serving.

Ingredient Substitutions

• Gluten‑free: Use a 1:1 gluten‑free flour blend in place of all‑purpose flour. Leavening and other components stay the same.
• Dairy‑free / Vegan: Replace buttermilk with a plant‑based milk + lemon juice, use vegan cream cheese and butter alternatives for the frosting, and substitute eggs with flax or chia egg equivalents (note texture may vary).
• Lower sugar: Reduce granulated sugar in the cake by ~1/4‑cup and adjust powdered sugar in frosting to taste.
• Alternate berries: Swap blackberries for raspberries, blueberries or a mixed berry filling for a different fruity profile.
• Colour twist: To amplify gothic visual, you can add a few drops of black or deep purple food colouring to the batter or frosting.

Serving Suggestions

• Serve each slice with a scoop of vanilla bean ice cream or a dollop of whipped cream for extra indulgence.
• Pair with a strong espresso or dark roast coffee—the bitterness balances the cake’s sweetness beautifully.
• For a dramatic presentation, top with edible gold leaf or cocoa‑dust swirl and place on a matte black or dark slate cake stand.
• Serve alongside a simple berry compote or fresh berry medley to echo flavours and add brightness.

Pro Tips

• Use parchment paper overhang in your cake pans so you can easily lift the baked layers out without damage.
• After cooling the cake layers, level the tops with a serrated knife so the layers stack evenly and the finished cake looks polished.
• When whipping the frosting, use chilled bowl and beaters—this helps the cream cheese mixture fluff up more easily.
• For cleaner slices, warm your knife under hot water, dry it, then wipe between each cut.
• Leftover blackberry filling is fantastic on toast, pancakes or yogurt—don’t let it go to waste.

Frequently Asked Questions

→ How long will the cake stay fresh?
When refrigerated, best enjoyed within 3 days. Beyond that the texture may soften and the filling may run.

→ Can I freeze slices of the assembled cake?
It’s not ideal after assembly because of the fresh filling and frosting, but you can freeze unfrosted layers, then thaw and assemble later.
