-
¾ cup unsweetened cocoa powder
-
2 teaspoons baking powder
-
1½ teaspoons baking soda

1 teaspoon salt
-
1 teaspoon espresso powder
-
1 cup milk (buttermilk, almond, or coconut milk all work)
-
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 berries for decoration)
For the Blackberry Frosting:
-
1 cup unsalted butter, softened
-
4 cups powdered sugar
-
½ cup blackberry purée (strained to remove seeds)
-
1 teaspoon vanilla extract
-
A pinch of salt

Instructions
Cake Layers:
-
Preheat your oven to 350°F (175°C). Grease and line four 8-inch cake pans with parchment paper.
-
In a large mixing bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, salt, and espresso powder.
-
Add in milk, oil, eggs, and vanilla extract. Mix at medium speed until well blended.
-
Carefully pour in the boiling water. The batter will be thin — that’s expected. Mix until smooth.
-
Gently fold in the chopped blackberries.
-
Divide the batter evenly among the prepared pans and bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
-
Let cakes cool in pans for 10 minutes, then transfer to wire racks to cool completely.
Blackberry Frosting:
-
Beat the softened butter until light and fluffy.
-
Gradually mix in the powdered sugar, one cup at a time.
-
Stir in the blackberry purée, vanilla extract, salt, and optional food coloring for a deep purple hue. Adjust the texture with more sugar (for thickness) or purée (for looseness) as needed.
Glossy Ganache:
-
Warm heavy cream in a saucepan over medium heat until it just begins to simmer — do not boil.
-
Pour over the chopped chocolate in a heatproof bowl and let sit for 1–2 minutes.
-
Add corn syrup or honey, and vanilla extract if using.
-
Stir slowly from the center outward with a spatula until the ganache is smooth, shiny, and luxurious.
Assembly:
-
Place your first cake layer on a cake stand or serving plate. Spread a layer of blackberry frosting over the top.
-
Repeat with the remaining layers. Use the remaining frosting to cover the sides of the cake.
-
Slowly pour the glossy ganache over the top, letting it cascade naturally down the sides.
-
Decorate with whole blackberries for an elegant, gothic finish.
