Raspberry Pistachio Mousse Cake Ingredients
For the Cake Base
- Ground Biscuit – Provides structure; use digestive biscuits or graham crackers for the best results.
- Ground Pistachio – Adds flavor and texture; almond flour makes a great substitution if needed.
- Butter – Acts as a binding agent; choose unsalted for enhanced flavor control.
For the Raspberry Bavarois
- Gelatin Leaves (8.5g) – Acts as a stabilizer; agar-agar is a vegetarian alternative.
- Milk (75ml) – Contributes creaminess; opt for almond or coconut milk for a dairy-free version.
- Caster Sugar (37g) – Provides sweetness; granulated sugar can be used as a substitute.
- Egg Yolks (45g) – Adds richness and aids in thickening; substitutes aren’t recommended here for texture.
- Raspberry Puree (75g) – Serves as the flavor base; fresh or frozen will work, but adjust sweetness if using fresh.

- Sugar (10g) – Sweetens the whipped cream for added balance.
For the Pistachio Mousse
- Milk (95g) – Acts as a creamy base; non-dairy alternatives provide equal creaminess.
- Pistachio Paste (50g) – Main flavor component; almond paste serves as a viable alternative in a pinch.
- Egg Yolks (2) – Reinforces richness; use the same substitution notes as above.
- Sugar (65g) – Imparts sweetness throughout the mousse.
- Gelatin (8.5g) – Stabilizer for the mousse; agar-agar can also be used as an alternative.

Step‑by‑Step Instructions for Raspberry Pistachio Mousse Cake
Step 1: Prepare the Cake Base
Begin by mixing the ground biscuits and ground pistachios in a large bowl. Melt the unsalted butter and combine it with the dry ingredients until the mixture resembles wet sand. Press this mixture evenly into the bottom of an 18cm round pan. Bake in a preheated oven at 180°C for approximately 12.5 minutes or until slightly golden. Allow it to cool completely before adding the next layer.
Step 2: Make Raspberry Bavarois
In a small bowl, bloom the gelatin leaves in cold water for about 5 minutes. While they soften, heat the milk with half of the caster sugar in a saucepan over medium heat. In a separate bowl, whisk together the remaining sugar with the egg yolks until pale. Temper the egg yolks by gradually adding the hot milk, then return the mixture to low heat until it thickens to 82°C. Stir in the bloomed gelatin and warm raspberry puree, then let it cool slightly.
Step 3: Fold in the Whipped Cream
While the raspberry mixture cools, whip the cream with 10g of sugar until soft peaks form. Gently fold the whipped cream into the cooled raspberry mixture, ensuring not to deflate it. Once combined, pour the raspberry bavarois over the cooled cake base and spread it into an even layer. Refrigerate the cake for at least 4 hours or until set.
Step 4: Create Pistachio Mousse
In a saucepan, heat the milk with the pistachio paste until just simmering. Meanwhile, whisk the egg yolks and sugar together in a separate bowl until light and fluffy. Gradually temper the yolk mixture with the hot milk, then transfer it back to the saucepan and cook until it thickens to 82°C. Remove from heat and fold in the bloomed gelatin when the mixture cools slightly.
Step 5: Combine with Whipped Cream
Whip the additional cream until soft peaks form, and gently fold this into the cooled pistachio mixture to maintain its airy texture. Ensure everything is well blended but still light and fluffy. Pour the pistachio mousse over the set raspberry bavarois layer, smoothing the top with a spatula. Refrigerate the entire cake overnight to allow both layers to meld beautifully.
Step 6: Finish and Serve the Cake
Once the mousse is fully set, remove the cake from the refrigerator, and carefully release it from the pan. Sprinkle the top with ground pistachios for added crunch and garnish with fresh raspberries for a pop of color. Slice the Raspberry Pistachio Mousse Cake into wedges and serve chilled, delighting your guests with this stunning dessert!
How to Store and Freeze Raspberry Pistachio Mousse Cake
Fridge: Keep the Raspberry Pistachio Mousse Cake covered in the refrigerator for up to 3 days to maintain its freshness and avoid drying out.
Freezer: For long-term storage, wrap individual slices tightly in plastic wrap, then in aluminum foil. The cake can last in the freezer for up to 1 month.
Thawing: To enjoy frozen slices, transfer them to the fridge for a few hours or overnight before serving, allowing them to thaw slowly while retaining their delightful texture.
Reheating: While typically served chilled, you can allow a slice to sit at room temperature for about 15 minutes for a softer experience, enhancing the flavor of the mousse.
Expert Tips for Raspberry Pistachio Mousse Cake
- Egg Tempering Technique: Ensure that you add the hot milk to the egg yolks slowly to prevent curdling, creating a velvety Bavarois.
- Chill Times Matter: Allow the cake to chill overnight; this enhances flavor melding and prevents the mousse layers from collapsing.
- Gelatin Substitutes: If using agar-agar instead of gelatin, remember it sets differently, so follow package directions for perfect stability in your Raspberry Pistachio Mousse Cake.
- Whip with Care: When folding whipped cream into your mixtures, be gentle! Overmixing can deflate the light, airy texture of your mousse.
- Presentation Counts: Before serving, add fresh raspberries and a sprinkle of ground pistachios to make the cake visually irresistible and even more inviting.

Raspberry Pistachio Mousse Cakes Recipe FAQs
What should I consider when selecting raspberries for this recipe?
Absolutely! When choosing raspberries, look for vibrant, plump berries without any dark spots. Fresh raspberries should be firm and give off a sweet aroma. Avoid any that are mushy or have signs of mold. If fresh raspberries aren’t available, frozen ones can be used, but ensure they’re thawed and drained before mixing into the Bavarois.
How should I store my Raspberry Pistachio Mousse Cake?
I recommend keeping the cake covered in the refrigerator, where it will stay fresh for up to 3 days. To avoid drying out, ensure you wrap it tightly with plastic wrap or store it in an airtight container. Adding fresh raspberries just before serving will maintain their freshness and flavor.
Can I freeze Raspberry Pistachio Mousse Cake?
Very! To freeze, wrap individual slices tightly in plastic wrap and then in aluminum foil. This way, the mousse cake can last in the freezer for up to 1 month. When you’re ready to enjoy it, simply move the slices to the refrigerator for several hours or overnight to thaw while retaining their lovely texture.
What should I do if my mousse didn’t set properly?
Don’t worry; it happens to the best of us! If the mousse hasn’t set, check if the gelatin was bloomed correctly or if the mixture was heated long enough to activate it. Next time, ensure that you fold the whipped cream gently, maintaining as much air as possible. If it still seems too soft, you can whip extra whipped cream and fold in another layer of gelatin to help it stabilize further.
Are there any dietary considerations to keep in mind?
Certainly! If you’re serving this dessert to guests with dietary restrictions, remember that gelatin is not vegetarian. In this case, substituting with agar-agar is a fantastic option for a vegetarian version. Moreover, you can use non-dairy milk and whipped cream for a dairy-free treat. Always check for allergens, especially since some guests may have nut allergies related to the pistachio content.
Can I customize the flavors in this mousse cake?
Absolutely! The beauty of this Raspberry Pistachio Mousse Cake lies in its versatility. You can easily swap out pistachio paste for almond paste to give it a different nutty flavor. Additionally, feel free to experiment with fruit purees such as mango or strawberry in place of raspberry for a delightful twist that matches your taste buds!
