¼ cup granulated sugar
2 teaspoons powdered gelatin
2 tablespoons cold water
1 cup heavy whipping cream (whipped to soft peaks)
For the Chocolate Mousse:
6 ounces dark chocolate (melted and cooled)
1 cup heavy whipping cream (whipped to soft peaks)
Directions
Prepare the Chocolate Cake Base:
Preheat the oven to 350°F (175°C).
Grease and line an 8-inch round cake pan with parchment paper.
In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, and salt.
Add the milk, melted butter, eggs, and vanilla extract. Mix until smooth.
Pour the batter into the prepared pan and bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool completely in the pan.
Prepare the Raspberry Mousse:
Puree the raspberries and sugar in a blender or food processor. Strain the mixture to remove seeds.
Sprinkle the gelatin over cold water in a small bowl and let it bloom for 5 minutes.
Gently heat the raspberry puree until warm, then stir in the bloomed gelatin until fully dissolved.
Allow the mixture to cool to room temperature.
Fold the whipped cream into the raspberry mixture until well combined.
Assemble the Cake:
Place the cooled chocolate cake layer at the bottom of a springform pan.
Pour the raspberry mousse over the cake layer, smoothing the top.
Refrigerate for at least 1 hour, or until the mousse is set.

FAQs
Can I use frozen raspberries for the mousse?
Yes, frozen raspberries can be used. Thaw them completely and drain any excess liquid before pureeing.
How can I ensure the mousse layers set properly?
Ensure that the gelatin is fully dissolved in the raspberry puree and that each mousse layer is adequately chilled before adding the next.
Can I make this cake in advance?
Absolutely. This cake can be made a day ahead and stored in the refrigerator until ready to serve.
What type of chocolate is best for the mousse?
Use high-quality dark chocolate with at least 60% cocoa content for a rich and smooth mousse.
Can I omit the gelatin?
Gelatin helps the mousse set properly. Omitting it may result in a softer texture that doesn’t hold its shape well.
How do I achieve clean slices when serving?
Use a sharp knife dipped in hot water and wiped dry before each cut to achieve clean slices.
Emma Duckworth Bakes
Can I add a glaze on top?
Yes, a chocolate ganache or mirror glaze can be added for an elegant finish.
Is it necessary to use a springform pan?
A springform pan is recommended for easy removal, but a regular cake pan lined with parchment paper can also be used.
How long should I chill the cake before serving?
Chill the assembled cake for at least 5 hours, or overnight, to ensure the mousse layers are fully set.
Can I add fresh raspberries between the layers?
Yes, adding fresh raspberries between the cake and mousse layers adds texture and enhances the raspberry flavor.
