Tools & Equipment

Fine-mesh strainer
Food processor
Large bowl
Medium saucepan
Offset spatula
Parchment paper
Silicone spatula
Small bowl
Stand mixer fitted with the whisk attachment

Recipe Tips

Fine Cookie Crumbs: For a firm and even crust, crush the cookies into fine crumbs using a food processor or rolling pin. Large chunks can make the crust crumbly.

Proper Gelatin Use: Soak gelatin sheets in cold water until soft, then squeeze out excess water. Add gelatin to warm raspberry purée, not hot or cold, to dissolve it properly.

Neat Removal: To ensure the cakes come out cleanly from the springform pans, first run a warm, thin knife around the edges. This helps release any mousse that may have stuck to the pan. Once the sides are loosened, gently unlatch the springform ring and lift it off carefully to maintain the cake’s smooth shape.

Fresh & Vibrant Look: For the best presentation, decorate the cake just before serving to keep the toppings looking fresh and visually appealing. If using fruit, wash and pat it dry beforehand to avoid excess moisture on the mousse.

Ingredients You Need for Raspberry Mousse Cake

For the Crust

Digestive cookies serve as the base of the cake, providing a crunchy texture and a slightly sweet, buttery flavor that complements the mousse.
Butter acts as a binding agent, helping to hold the crushed cookies together and form a firm, cohesive crust.
Salt enhances the overall flavor profile by balancing the sweetness and intensifying the taste of the crust.

For the Raspberry Mousse Filling

Raspberries are the main flavor component of the mousse, offering a naturally sweet and slightly tart taste while also contributing to the vibrant pink color.
Granulated sugar sweetens the mousse, balancing the acidity of the raspberries and ensuring a smooth, pleasant flavor.
Gelatin sheets provide structure and stability to the mousse, allowing it to set properly while maintaining a light and airy texture.
Greek yogurt adds a creamy, slightly tangy element that enhances the richness of the mousse and balances its sweetness.
Vanilla bean paste brings warm, aromatic notes that complement the raspberries and deepen the overall flavor.
Heavy cream is whipped to incorporate air, making the mousse light, fluffy, and smooth in texture.

Directions – How to Make Raspberry Mousse Cake

Make the Crust

Line two 12cm (5-inch) heart-shaped springform pans with parchment paper and set aside. Pulse the digestive cookies in a food processor until finely ground.

Melt the butter in the microwave. Add the melted butter to the cookie crumbs and pulse until well combined. Press the mixture firmly into the bottom of the prepared pans to form an even crust. Chill for at least 30 minutes to set.

Make the Raspberry Mousse

In a medium saucepan, combine frozen raspberries, 40g of granulated sugar, and 1 tablespoon of water. Simmer over medium heat until the raspberries are completely broken down.

Strain the raspberry mixture through a fine-mesh strainer to remove seeds. Soak the gelatin in cold water for about 5 minutes, then squeeze out excess water. Add the softened gelatin to the warm raspberry purée and stir until fully dissolved. Let it cool.

In a large bowl, mix Greek yogurt, the remaining sugar, and vanilla bean paste until smooth. Gently fold the cooled raspberry purée into the yogurt mixture.

In a stand mixer fitted with a whisk attachment, whip the heavy cream on medium speed until stiff peaks form, about 1.5 minutes. Carefully fold the whipped cream into the raspberry-yogurt mixture until fully incorporated.

Assemble the Cake

Spread some raspberry mousse over the chilled crust. Arrange raspberries on top of the mousse layer. Pour the remaining mousse over the raspberries, spreading evenly. Smooth the surface, then gently tap the pans on the counter to remove any air bubbles. Chill until set, for at least 4 hours.

Run a warm, thin knife around the edges of the springform pan, then carefully release the cakes from the pans and transfer to a serving platter. Decorate as desired with fresh raspberries, chopped chocolate, and sugar pearls for an elegant finish.

Storing and Freezing Instructions

Storing: Keep the cake in the fridge, covered with plastic wrap or in an airtight container. This keeps the mousse from drying out. The cake will stay fresh for 2-3 days in the fridge, but it is best enjoyed within 24 hours for the best texture and flavor.
Freezing: Place the cake on a flat tray and freeze it uncovered for about 1 hour, or until firm. Once set, wrap it tightly in plastic wrap, followed by a layer of aluminum foil. Alternatively, place it in an airtight container. The cake can be frozen for up to 2 months. If freezing individual slices, separate them with parchment paper before wrapping to make thawing easier.
Thawing: Transfer the frozen cake to the fridge and let it thaw slowly for 6-8 hours or overnight. This gradual thawing helps maintain the mousse’s smooth texture and prevents excess moisture from forming. Avoid thawing at room temperature, as the mousse may soften too quickly and lose its structure. Before serving, remove the wrapping and let the cake sit at room temperature for 10-15 minutes for the best flavor and consistency.
