Ingredients
For the Cake:
- 2 cups all-purpose flour
- 2 cups sugar
- ¾ cup unsweetened cocoa powder
- 2 teaspoons baking powder
- 1.5 teaspoons baking soda
- 1 teaspoon salt
- 1 teaspoon espresso powder
- 1 cup milk (buttermilk, almond, or coconut milk can be used)
- ½ cup vegetable oil (or melted coconut oil)
- 2 large eggs
- 2 teaspoons vanilla extract
- 1 cup boiling water
- 1 cup fresh blackberries, chopped (plus extra whole blackberries for decoration)
For the Blackberry Frosting:
- 1 cup unsalted butter, softened
- 4 cups powdered sugar
- ½ cup blackberry puree (strained to remove seeds, from fresh or frozen blackberries)
- 1 teaspoon vanilla extract
- A pinch of salt
- Purple or aubergine food coloring (optional)
For the Glossy Ganache:
- 1 cup heavy cream
- 1 cup dark chocolate, finely chopped
- 2 tablespoons light corn syrup or honey
- ½ teaspoon vanilla extract (optional)
Instructions
- Prepare the Cake Batter: In a large mixing bowl, sift together the all-purpose flour, sugar, unsweetened cocoa powder, baking powder, baking soda, salt, and espresso powder. In a separate bowl, whisk together the milk of choice, vegetable or melted coconut oil, eggs, and vanilla extract until smooth. Gradually combine the wet ingredients into the dry ingredients, mixing gently to combine.
- Add Boiling Water and Blackberries: Carefully stir in the boiling water to the batter; this will thin out the mixture and help create a moist cake. Fold in the chopped fresh blackberries gently to distribute the berries without breaking them up too much.
- Bake the Cake: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. Divide the batter evenly between the pans and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Remove from the oven and let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
- Make the Blackberry Frosting: Using a mixer, beat the softened unsalted butter until creamy. Gradually sift in the powdered sugar, beating well to combine. Add the blackberry puree, vanilla extract, and a pinch of salt. Mix until the frosting is smooth and fluffy. Add purple or aubergine food coloring if desired to enhance the color.
- Prepare the Glossy Ganache: In a small saucepan, heat the heavy cream until it just begins to simmer. Remove from heat and pour over the finely chopped dark chocolate in a heatproof bowl. Let it sit for 2-3 minutes, then stir gently until the chocolate is completely melted and the ganache is smooth. Stir in the light corn syrup or honey and vanilla extract, if using, to achieve a shiny, smooth finish.
- Assemble the Cake: Place one cooled cake layer on your serving plate. Spread a generous amount of blackberry frosting evenly on top. Add the second cake layer and frost the top and sides with the remaining blackberry frosting.
- Apply the Ganache: Pour the glossy ganache over the frosted cake, letting it drip down the edges to create an elegant finish. Use a spatula to smooth the ganache, if needed.
- Decorate: Garnish the top of the cake with extra whole fresh blackberries for a decorative touch. Chill the assembled cake in the refrigerator for at least 30 minutes to set the ganache before serving.
Notes
- Espresso powder enhances the chocolate flavor but can be omitted if desired.
- Use fresh or frozen blackberries, but be sure to puree and strain the frosting to remove seeds for a smooth texture.
- Boiling water in the cake batter helps to develop the cocoa flavors and keeps the cake moist.
- The ganache should be poured warm but not hot to avoid melting the frosting.
- For a dairy-free version, substitute milk with almond or coconut milk, butter with non-dairy margarine, and use dairy-free chocolate and cream alternatives.
- Store the cake refrigerated and bring to room temperature before serving for best taste.
