Instructions

Step 1: Make the Chocolate Cake Base

1. Preheat the oven to 350°F (175°C). Grease and line an 8-inch round cake pan with parchment paper.
2. In a bowl, whisk together flour, cocoa powder, baking powder, and salt.
3. In another bowl, beat eggs and sugar until light and fluffy. Stir in melted butter and vanilla.
4. Gradually mix in the dry ingredients, alternating with milk, until fully combined.
5. Pour the batter into the prepared pan and bake for 15–18 minutes or until a toothpick inserted in the center comes out clean. Let cool completely.

Step 2: Prepare the Raspberry Layer

1. In a small saucepan, combine raspberries, sugar, and lemon juice over medium heat.
2. Stir occasionally until raspberries break down, about 5 minutes.
3. Add the cornstarch slurry and cook for another 2–3 minutes until thickened.
4. Strain the mixture through a fine-mesh sieve to remove seeds, then let it cool.

Step 3: Make the Chocolate Mousse

1. In a heatproof bowl, melt chocolate and butter over a double boiler until smooth. Stir in vanilla and set aside.
2. In a separate bowl, whisk egg yolks and sugar until pale.
3. Heat 1/4 cup heavy cream until warm but not boiling, then slowly pour it into the egg mixture while whisking continuously.
4. Return the mixture to the saucepan and cook over low heat, stirring constantly, until slightly thickened (do not boil).
5. Remove from heat and stir in the gelatin mixture until fully dissolved.
6. Fold in the melted chocolate mixture.
7. Whip the remaining 1 cup of heavy cream to stiff peaks and gently fold it into the chocolate mixture.

Step 4: Assemble the Cake

1. Place the cooled chocolate cake base in a springform pan.
2. Spread the raspberry layer evenly over the cake.
3. Gently pour the chocolate mousse over the raspberry layer, smoothing the top.
4. Refrigerate for at least 4 hours or until set.

Step 5: Garnish and Serve

1. Remove the cake from the springform pan.
2. Decorate with fresh raspberries, chocolate shavings, or whipped cream.
3. Slice and serve chilled.

Frequently Asked Questions

How can I make this cake ahead of time?

You can prepare the entire cake a day in advance and store it in the fridge until ready to serve.

Can I use store-bought raspberry jam instead of fresh raspberries?

What type of chocolate is best for the mousse?

Use high-quality semi-sweet or dark chocolate (50–70% cocoa) for a rich and balanced taste.

Can I make this cake without gelatin?

Yes! Use a square pan for a layered mousse bar effect or make individual mousse cups.

How do I cut the cake neatly?

Use a warm knife (dip in hot water and wipe dry) for clean slices.

Can I skip the chocolate cake base?

Yes, you can make it a crustless mousse cake or replace it with a cookie or biscuit crust.

What can I serve with this cake?

A dollop of whipped cream, extra raspberry sauce, or a side of vanilla ice cream pairs beautifully.
