- 2 teaspoons pure vanilla extract

- 1 cup (170g) mini semi-sweet chocolate chips (tossed in 1 tablespoon flour)
Raspberry Filling
To create the vibrant and tangy raspberry filling:
- 1½ tablespoons (22ml) water
- 1½ tablespoons (4.5 teaspoons or 12g) cornstarch
- 3 cups (12 ounces/about 340–375g) fresh or frozen raspberries
- ⅓ cup (67g) granulated sugar
- 1 teaspoon lemon juice

Chocolate Buttercream
For the creamy chocolate buttercream frosting:
- 1 cup (226g) unsalted butter, softened to room temperature
- 3½ cups (420g) confectioners’ sugar
- ½ cup (41g) unsweetened natural or dutch-process cocoa powder
- 3 tablespoons (45ml) heavy cream or milk
- ⅛ teaspoon salt
- 2 teaspoons pure vanilla extract
Chocolate Raspberry Ganache
To top the cake with a silky ganache:
- 8 ounces (226g) quality semi-sweet or bittersweet chocolate, finely chopped
- ¾ cup (180ml) heavy cream or heavy whipping cream
- ¼ cup (60ml) raspberry liqueur, such as Chambord (or replace with more heavy cream)
Making the Raspberry Filling
Start by preparing the raspberry filling, as it needs time to cool and thicken.
- In a small bowl, whisk the cornstarch and water until fully dissolved.
- Combine the cornstarch mixture, raspberries, sugar, and lemon juice in a medium saucepan.
- Cook over medium heat, stirring occasionally, until the mixture thickens and comes to a boil.
- Remove from heat and stir in the vanilla extract.
- Let the filling cool to room temperature, then refrigerate for at least 4 hours to thicken fully.
Preparing the Chocolate Cake
While the filling chills, bake the chocolate cake layers.
- Preheat the oven to 350°F (177°C). Grease and line three 9-inch cake pans with parchment paper.
- In a large bowl, whisk together the flour, cocoa powder, sugar, baking soda, baking powder, salt, and espresso powder.
- In a separate bowl, mix the oil, eggs, and sour cream until well combined.
- Add the buttermilk and vanilla extract to the wet ingredients, then combine with the dry ingredients.
- Stir in the hot water or coffee to the batter, followed by the chocolate chips.
- Divide the batter evenly among the prepared pans and bake for 24–26 minutes, or until a toothpick inserted into the center comes out clean.
- Allow the cakes to cool completely before assembling.

Making the Chocolate Buttercream
The chocolate buttercream frosting is essential for adding richness and structure to the cake.
- Beat the butter on medium speed until creamy.
- Gradually add the confectioners’ sugar and cocoa powder, mixing until smooth.
- Add the heavy cream, salt, and vanilla extract, and beat on high speed until the frosting is light and fluffy.
- If the frosting is too thick, add more cream; if too thin, add more confectioners’ sugar.

Assembling the Cake
Now that all the components are ready, it’s time to assemble your cake.
- Layering the Cake:
- Place one cooled cake layer on a serving plate.
- Spread a thin layer of chocolate buttercream on top.
- Pipe a thick border of buttercream around the edge to create a dam for the raspberry filling.
- Spoon half of the filling within the buttercream border.
- Repeat with the second layer, then place the third layer on top.
- Crumb Coating:
- Spread a thin layer of buttercream over the top and sides of the cake to seal in crumbs.
- Refrigerate for at least 30 minutes to set the crumb coat.
Preparing the Chocolate Raspberry Ganache
While the cake chills, prepare the chocolate raspberry ganache.
- Heat the cream and raspberry liqueur (if using) until just simmering.
- Pour the hot mixture over the chopped chocolate and let sit for a few minutes.
- Stir gently until smooth and glossy, then allow to cool slightly before spreading over the cake.
Decorating Tips
For a simple yet elegant finish:
- Use an icing spatula to smooth the ganache over the top and sides of the cake.
- Garnish with fresh raspberries and mint leaves for a pop of color.
