Raspberry Pistachio Mousse Cakes bring together the creamy richness of nuts and the lively burst of berries in every layer. Each bite balances a melt-in-your-mouth texture with tangy fruit and a delicate nutty crunch. I love making these as a showstopper dessert for spring and summer gatherings—the layers look beautiful and always taste even better than they look.
The first time I made this was for my mom’s birthday. Everyone was surprised when I sliced into the cake and revealed the different pastel layers. Now it is my most requested family dessert.
Ingredients
- Pistachios: Choose roasted unsalted for the base as these provide the deepest nutty flavor and a satisfying crunch. If possible look for those with bright green color for best appearance
- Almond flour: Finely ground almond flour creates a light and tender cake base. Opt for finely milled for even mixing
- Butter: Unsalted butter is best for controlling sweetness and lends a rich mouthfeel to the crust
- Sugar: Granulated sugar for gentle sweetness in all layers. Taste your fruit puree before sweetening to avoid overdoing it
- Egg: Select fresh and room-temperature eggs to help with even blending in the cake base
- Vanilla extract: Pure vanilla makes each layer taste mellow and warm. Check labels to ensure you are using real vanilla
- Heavy cream: Choose a high fat heavy cream for volume and silky texture in mousse layers
- Gelatin powder: Always bloom your gelatin in cold water first to keep the mousse perfectly creamy and stable. Fresh gelatin works better than expired
- Raspberries: Use fresh when in season for bold color and bright flavor. If using frozen let them thaw completely before blending and straining
- Lemon juice: Pick fresh lemons if possible since bottled can be dull. This sharpens the compote and enhances the raspberry mousse
- Cornstarch: Helps thicken the compote to prevent a runny texture. Check that yours is lump free for best results
Step-by-Step Instructions
- Make and Bake Cake Base:
- Pulse pistachios in a food processor until very fine then add almond flour sugar melted butter egg and vanilla. Press evenly into the bottom of lined molds or baking pan. Bake at moderate heat until just set and starting to brown at the edge. Fully cool before layering.
- Blend and Prepare Pistachio Mousse:
- Blend pistachios finely then in a mixer whip heavy cream to soft peaks. Bloom gelatin by sprinkling it over cold water and waiting until it looks spongy then gently warm. Mix pistachio paste sugar and vanilla into whipped cream then carefully fold in gelatin mixture. Spread or pipe onto cooled base and refrigerate until set.
- Cook Raspberry Compote:
- Puree raspberries and strain out seeds if desired. Simmer puree with sugar lemon juice and a slurry of cornstarch in a saucepan over low heat. Stir gently until thickened and glossy. Let cool before spooning over pistachio mousse.
- Whip and Pipe Raspberry Mousse:
- Whip heavy cream to soft peaks in a clean bowl. Puree raspberries with sugar then bloom and melt gelatin as in previous step. Gently fold raspberry puree and vanilla into whipped cream then incorporate the gelatin completely. Spread or pipe evenly over set raspberry compote. Chill thoroughly to set all layers.
- Garnish and Serve:
- Unmold chilled cakes carefully and top with extra raspberries or chopped pistachios if desired. Serve well chilled for best flavor and clean layers.

My favorite part of this recipe is tasting the fresh raspberry mousse before it sets. I always sneak a spoonful and remember the first time my sister and I baked these together for a family party. Everyone argued over the last slice.
Storage Tips
These mousse cakes keep beautifully for up to three days in the refrigerator. Cover tightly to prevent them from picking up fridge odors. For longer storage freeze the unmolded cakes on a tray then wrap individually for up to two months thawing overnight in the refrigerator.
Ingredient Substitutions
No almond flour Use finely ground hazelnuts instead for a delicious variation. If you are out of fresh raspberries swap for blackberries or finely strained strawberries for a creative twist in the layers. For dairy free use coconut cream in place of heavy cream—just chill it well beforehand.
Serving Suggestions
Plate each individual cake on a bright dessert plate and drizzle raspberry puree or white chocolate sauce nearby. Sprinkle chopped pistachios or crystallized rose petals for added flair. I often serve these after a light salad and grilled fish for a stunning summer dinner.
The Cultural Story
Layered mousse cakes with nuts and fruit are favorites all around the Mediterranean. Pistachios especially are celebrated in both Middle Eastern and Italian sweets. Combining them with fresh berries is my nod to the French patisserie traditions that have always inspired me to try new combinations.
Recipe FAQs
- → What makes the mousse layers so light?
The secret lies in properly whipping heavy cream and gently folding it into the mousse base, which includes pureed pistachios or raspberries along with bloomed gelatin for stability.
- → How do I ensure the base is crunchy?
Use roasted pistachios and almond flour mixed with melted butter and egg, then bake until lightly golden to achieve a sturdy, crunchy base.
- → Can I use frozen raspberries?
Yes, frozen raspberries work well. Thaw them completely and blend until smooth before using in the compote and mousse layers.
- → Why is gelatin used in the mousse?
Gelatin ensures the mousse holds its structure, creating stable, sliceable layers without compromising on creaminess.
