Method
- Step 1: Make the Blackberry Puree
- Rinse the blackberries. Blend until smooth. Push the puree through a fine strainer to remove the seeds. You’ll need 1 cup for the cake and the rest for the filling.
- Step 2: Prepare the Cake Batter
- Cream Butter and Sugar
- In a large bowl, beat the butter and sugar until pale and fluffy. This traps air and makes a soft cake crumb.
- Add Blackberry Puree and Eggs
- Add eggs one at a time. Beat well after each. Stir in the blackberry puree and oil until smooth.
- Mix in Dry Ingredients
- In a separate bowl, whisk flour, cocoa powder, baking powder, baking soda, and salt. Add this to the wet mix, alternating with the buttermilk. Stir until just combined. Finish with vanilla extract.
- Step 3: Bake the Cake Layers
- Preheat oven to 350°F (175°C). Grease and line two 8-inch cake pans. Divide the batter between them.
- Bake for 25–30 minutes. A toothpick should come out clean. Cool in pans for 10 minutes, then move to a rack.
- Step 4: Cook the Blackberry Filling
- In a small saucepan, cook blackberries, sugar, and lemon juice over medium heat until the fruit softens.
- Mix cornstarch with water. Stir this into the pan. Cook until thickened. Let it cool.
- Step 5: Make the Chocolate Ganache
- Warm the cream in a small pot until it just starts to bubble. Remove from heat. Pour over chopped chocolate and butter.
- Let it sit for 2–3 minutes. Stir until smooth and glossy. Let it cool slightly before using.
- Step 6: Assemble the Cake
- Add the Filling
- Place the first cake layer on a plate. Spread a generous layer of blackberry filling across the top.
- Pour the Ganache
- Set the second layer on top. Pour ganache over the cake, letting it drip down the sides.
- Final Touches
- Top the cake with fresh blackberries. Add chocolate shavings and flowers if you like. A dusting of cocoa adds a moody look.
