Chocolate Cake Layer
This moist and fudgy chocolate cake serves as the foundation of our dessert.
Ingredients
- 1 cup (120g) all-purpose flour
- ½ cup (50g) unsweetened cocoa powder
- ¾ cup (150g) granulated sugar
- ½ teaspoon baking soda
- ½ teaspoon baking powder
- ¼ teaspoon salt
- ½ cup (120ml) buttermilk
- ¼ cup (60ml) vegetable oil
- 1 large egg
- 1 teaspoon vanilla extract
- ½ cup (120ml) hot coffee or hot water
Instructions
- Preheat Oven & Prep Pan – Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan and line it with parchment paper.
- Mix Dry Ingredients – In a large bowl, whisk together flour, cocoa powder, sugar, baking soda, baking powder, and salt.
- Combine Wet Ingredients – In a separate bowl, mix buttermilk, oil, egg, and vanilla extract.
- Mix Batter – Slowly add wet ingredients to the dry mixture. Pour in hot coffee and stir until smooth.
- Bake – Pour the batter into the prepared pan and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
- Cool – Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

Raspberry Jelly Layer
This tangy raspberry jelly layer adds a refreshing burst of fruitiness that perfectly balances the rich chocolate flavors.
Ingredients
- 2 cups (250g) fresh or frozen raspberries
- ⅓ cup (65g) granulated sugar
- 2 tablespoons lemon juice
- 1 tablespoon water
- 2 teaspoons powdered gelatin (or 1 gelatin sheet)
Instructions
- Prepare Gelatin – In a small bowl, sprinkle the gelatin over 1 tablespoon of water. Let it sit for 5 minutes to bloom.
- Cook Raspberries – In a saucepan over medium heat, combine raspberries, sugar, and lemon juice. Stir until the raspberries break down and release their juices, about 5-7 minutes.
- Strain – Pour the raspberry mixture through a fine mesh sieve into a clean bowl to remove the seeds, pressing down with a spoon to extract all the juice.
- Add Gelatin – While the raspberry mixture is still warm, stir in the bloomed gelatin until fully dissolved.
- Chill – Pour the mixture into a parchment-lined 9-inch springform pan and refrigerate for 1-2 hours, until set and firm to the touch.

Chocolate Mousse Layer
This silky chocolate mousse is light, airy, and melts in your mouth, making it the perfect layer to complement the rich cake and tangy jelly.
Ingredients
- 1 ½ cups (260g) semi-sweet or dark chocolate, chopped
- 2 cups (480ml) heavy whipping cream, divided
- 3 tablespoons (45g) unsalted butter
- ¼ cup (30g) powdered sugar
- 1 teaspoon vanilla extract
Instructions
- Melt Chocolate – In a heatproof bowl, combine chopped chocolate and butter. Place the bowl over a saucepan of simmering water (double boiler method) and stir until smooth and melted. Set aside to cool slightly.
- Whip Cream – In a separate bowl, whip 1 ½ cups of heavy cream with powdered sugar and vanilla extract until soft peaks form.
- Fold Together – Once the melted chocolate has cooled to room temperature, gently fold the whipped cream into the chocolate mixture in batches. Be careful not to deflate the mousse—use slow, gentle movements.
- Chill – Refrigerate the mousse for at least 30 minutes to firm up before assembling the cake.
Assembling the Cake & Chocolate Ganache
Now it’s time to bring all the layers together and finish with a glossy, decadent ganache. This is where the magic happens!
Ingredients for Chocolate Ganache
- 1 cup (170g) semi-sweet or dark chocolate, chopped
- ¾ cup (180ml) heavy cream
- Fresh raspberries, for topping
Assembling the Cake
- Layer the Cake Base – Place the cooled chocolate cake layer at the bottom of a 9-inch springform pan.
- Add Raspberry Jelly Layer – Carefully place the set raspberry jelly layer on top of the cake. If the edges don’t line up perfectly, you can trim them slightly.
- Spread Chocolate Mousse – Pour the chilled chocolate mousse over the raspberry jelly layer. Use an offset spatula to smooth the top evenly.
- Chill – Refrigerate the assembled cake for at least 2 hours (or overnight) to let the layers firm up.
Making the Ganache
- Heat the Cream – In a small saucepan, heat the heavy cream over medium heat until it just starts to simmer (don’t let it boil).
- Pour Over Chocolate – Place the chopped chocolate in a heatproof bowl and pour the hot cream over it. Let it sit for 2-3 minutes.
- Stir Until Smooth – Gently stir until the chocolate is completely melted and the ganache is glossy and smooth. Let it cool slightly.
Finishing Touches
- Pour Ganache – Once the ganache has cooled to a pourable consistency, pour it over the chilled mousse layer. Use an offset spatula to spread it evenly, letting some drip down the sides for a dramatic effect.
- Decorate – Top with fresh raspberries for a pop of color and extra fruity flavor.
- Final Chill – Chill the cake for another 30 minutes to set the ganache before slicing and serving.
Serving Suggestions
- Perfect Slice Tip: For clean slices, dip your knife in hot water and wipe it dry between cuts.
- Optional Garnishes: Add a sprinkle of powdered sugar, a drizzle of raspberry coulis, or a few mint leaves for a fresh touch.
- Pair It With: A cup of coffee, a glass of red wine, or a dollop of whipped cream for the ultimate dessert experience.
Storing the Cake
- Refrigeration: Store the cake in an airtight container in the fridge for up to 4 days.
- Freezing: You can freeze individual slices or the whole cake (without the fresh raspberries) for up to 1 month. Wrap it tightly in plastic wrap and foil. Thaw in the refrigerator overnight before serving.
- Make-Ahead Tip: You can prepare the cake layers a day ahead and assemble the next day to save time.
