Save to Pinterest This exquisite French dessert features a delicate almond sponge base that provides nutty depth and structure, topped with velvety raspberry mousse that balances sweetness and tartness perfectly. The airy sponge contrasts beautifully with the creamy mousse layer, creating a sophisticated texture that melts in your mouth. Fresh raspberries on top add vibrant color and juicy bursts. Ideal for summer entertaining, dinner parties, or whenever you want an elegant finale that isn't overly heavy.
The summer my grandmother visited from Paris, she made this exact cake for my birthday dinner. I remember watching her fold the egg whites with such gentle precision, her hands moving like she was conducting music. That evening, as we sliced through those layers of cloud-like mousse and nutty sponge, I understood why French desserts feel like edible poetry.
Last summer I made this for a dinner party when the temperature hit ninety degrees. Watching my friends take that first bite, their eyes closing at how something so light could feel so luxurious, I knew this wasnt just dessert. It was the kind of dessert that makes people lean back in their chairs and talk for hours.
Ingredients
- Almond flour (100 g): This creates the sponge's signature nutty foundation and keeps it incredibly moist
- All-purpose flour (50 g): Just enough structure to hold those delicate air pockets without weighing anything down
- Granulated sugar (100 g): Split between yolks and whites for proper aeration and tender crumb
- 4 large eggs, separated: The yolks enrich while whipped whites create that signature lift
- Unsalted butter (30 g), melted and cooled: Adds richness without making the sponge heavy
- Vanilla extract (1/2 tsp): Rounds out the almond flavor beautifully
- Salt (pinch): Wakes up all the flavors
- Fresh or frozen raspberries (300 g): Frozen works perfectly, just thaw completely first
- Granulated sugar (100 g): Balances the berries natural tartness
- Lemon juice (2 tbsp): Makes the raspberry flavor sing instead of just being sweet
- Leaf gelatin (5 sheets) or powdered gelatin (12 g): Leaf gelatin gives a silkier texture but both work beautifully
- Heavy cream (300 ml), cold: Must be very cold for proper whipping and stable mousse
- Fresh raspberries (150 g): The crowning glory, choose plump ones for the prettiest presentation
- Powdered sugar (1 tbsp): For that elegant snowy finish
- Mint leaves: A pop of color and freshness that makes everything feel complete
Instructions
- Prepare your pan and oven:
- Preheat to 180°C (350°F) and line a 23 cm springform pan with parchment paper, greasing the sides lightly
- Make the yolk base:
- Beat yolks with 50 g sugar until pale and thick, then gently fold in melted butter and vanilla
- Whip the whites:
- Whisk whites with salt to soft peaks, gradually adding remaining 50 g sugar until stiff and glossy
- Combine everything:
- Fold almond and all-purpose flour into yolks, then fold in one third of whites to lighten before gently incorporating the rest
- Bake the sponge:
- Pour into prepared pan and bake 18 to 20 minutes until golden and a toothpick comes out clean, then cool completely
- Prepare the gelatin:
- Soak leaf gelatin in cold water for 5 minutes while you work on the fruit
- Make raspberry puree:
- Blend raspberries with sugar and lemon juice, then strain through a fine mesh sieve to catch all the seeds
- Melt the gelatin:
- Warm one third of the puree gently, stir in squeezed gelatin until dissolved, then combine with remaining puree and cool to room temperature
- Whip the cream:
- Beat cold heavy cream to soft peaks, watching carefully so it stays silky
- Make the mousse:
- Fold cooled raspberry mixture into whipped cream until completely smooth and uniform
- Assemble the cake:
- Spread mousse evenly over cooled sponge, smooth the top, and chill at least 4 hours until completely set
- Finish with flair:
- Release from pan, arrange fresh raspberries on top, dust with powdered sugar, and tuck in mint leaves if you like
Save to Pinterest This cake has become my go-to when I want to make someone feel special without spending all day in the kitchen. Something about that combination of nutty, creamy, and bright makes people remember the meal long after the plates are cleared.
Making It Ahead
The entire cake can be made two days ahead and kept covered in the refrigerator, actually improving in texture as the flavors meld together. The mousse sets more firmly, making slicing cleaner and each bite more cohesive.
Working With Gelatin
If you have never used leaf gelatin before, it dissolves more evenly than powdered and creates this silky texture that feels more professional. Just be sure to squeeze out all the water after soaking so your mousse does not become watery.
Serving Suggestions
A chilled glass of Moscato dAsti plays beautifully with the raspberry brightness, or serve with strong espresso to cut through the richness. Let the cake sit at room temperature for 15 minutes before serving so the mousse softens slightly.
- Run a thin knife around the edge before releasing the springform pan
- Use fresh raspberries that are slightly firm for the best appearance
- Dust with powdered sugar right before serving so it does not dissolve

Recipe Questions & Answers
- → Can I make this dessert ahead of time?
-
Yes, this actually improves when made ahead. The mousse needs at least 4 hours to set properly, so preparing it the day before serving is ideal. Keep it refrigerated until ready to garnish with fresh berries.
- → Can I use frozen raspberries for the mousse?
-
Absolutely. Frozen raspberries work wonderfully in the mousse layer since they'll be pureed. Thaw them completely before pureeing and strain well to remove seeds for the smoothest texture.
- → How do I prevent the sponge from sinking into the mousse?
-
Ensure the sponge is completely cooled before adding the mousse. You can also spread a thin layer of cooled mousse over the sponge first and chill for 15 minutes before adding the remainder.
- → What's the best way to get clean slices?
-
Run a sharp knife under hot water, wipe dry, and slice between cuts. The heat helps cut through the mousse cleanly. Wipe the knife clean between each slice.
- → Can I make this gluten-free?
-
Yes, simply substitute the all-purpose flour with a quality gluten-free flour blend. The almond flour naturally provides structure, so the texture remains excellent.
- → How should I store leftovers?
-
Cover tightly and refrigerate for up to 3 days. The fresh berry topping is best added within a few hours of serving, but the mousse and sponge layers keep beautifully.
