Ingredients You’ll Need
Gathering the ingredients for this cake is a breeze, and each one plays a crucial role in bringing the flavors and textures to life. From the tangy berries to the rich cream, every component is essential to crafting that signature mousse experience.
- Mixed berries (1 1/2 cups): Fresh or frozen, these provide the bright, fruity base bursting with natural sweetness and color.
- Granulated sugar (1/4 cup): Balances the tartness of the berries, creating the perfect harmony.
- Lemon juice (2 tablespoons): Adds a zesty kick that elevates the berry flavor.
- Unflavored gelatin (2 teaspoons): Gives the mousse its delicate structure and sets the layers just right.
- Cold water (2 tablespoons): Used to bloom the gelatin for smooth incorporation.
- Heavy whipping cream (1 1/2 cups): Whipped to fluffy perfection, providing rich, creamy texture.
- Powdered sugar (1/4 cup): Sweetens the cream without graininess, ensuring a silky finish.
- Vanilla extract (1 teaspoon): Adds a warm, aromatic undertone that complements the berries beautifully.
- Prepared sponge cake layer (8 or 9 inches): A light and airy foundation to soak up the mousse layers gracefully.
- Fresh berries and mint leaves (optional): For garnish, adding a fresh and elegant touch.
How to Make Berry Layered Mousse Cake Recipe
Step 1: Prepare the Berry Puree
Start by combining the mixed berries, granulated sugar, and lemon juice in a small saucepan over medium heat. Cook gently for about 5 to 7 minutes until the berries break down and release their juices, creating a vibrant and fragrant berry mix. For a silky mousse without seeds, puree this mixture with a fork or blender, then strain it.
Step 2: Bloom and Dissolve the Gelatin
Sprinkle the gelatin over cold water in a small bowl and let it sit for 5 minutes until it blooms, which means it absorbs the water and swells. Warm the gelatin gently until fully dissolved, then stir it into the berry puree ensuring a smooth texture that will firm up the mousse wonderfully.
Step 3: Whip the Cream
In a separate bowl, whip the heavy whipping cream along with powdered sugar and vanilla extract until it reaches medium peaks. Be careful not to overwhip— you want soft but stable peaks that will fold beautifully with the berry mixture.
Step 4: Combine the Mousse
Allow the berry and gelatin mixture to cool to room temperature before gently folding it into the whipped cream. This step requires a light hand to keep the mousse airy and fluffy, so mix until fully combined but still voluminous.
Step 5: Assemble the Cake
Place the prepared sponge cake layer into a springform pan or a cake ring to create a mold. Pour the luscious berry mousse evenly over the sponge, smoothing the top with a spatula.
Step 6: Chill to Set
Refrigerate your cake for at least 4 hours to allow the mousse to set firmly. This chilling step is crucial to achieve those perfect layers and ensures the cake slices cleanly.
Step 7: Garnish and Serve
Once set, carefully remove the cake from its mold and adorn with fresh berries and mint leaves for a stunning finish. Your Berry Layered Mousse Cake is now ready to impress!
How to Serve Berry Layered Mousse Cake Recipe

Garnishes
Fresh berries such as raspberries, blueberries, or strawberries sprinkled on top along with a few fragrant mint leaves make for a visually striking and flavorful garnish. A light dusting of powdered sugar adds a delicate, snowy touch that elevates its refined look and taste.
Side Dishes
Pair this airy berry mousse cake with a simple side of vanilla ice cream or a dollop of whipped cream to enhance the creamy texture. For a more substantial pairing, a cup of robust coffee or a glass of sparkling rosé will beautifully complement the fresh fruitiness of the dessert.
Creative Ways to Present
You can turn this cake into individual parfaits by layering mousse and cake cubes in clear glasses. Alternatively, use different berry flavors for each mousse layer to create a stunning rainbow effect that will wow your guests both visually and taste-wise. Serving it with edible flowers is another lovely way to impress.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Berry Layered Mousse Cake Recipe covered tightly in the refrigerator for up to 3 days. This preserves its freshness and texture without the mousse weeping or the cake becoming soggy. Using an airtight container is ideal to maintain its delicate aroma and moisture.
Freezing
Freezing this cake is possible but with a slight texture change in the mousse. Wrap the cake tightly in plastic wrap and then foil to prevent freezer burn. Thaw overnight in the fridge before serving. Be aware the mousse may not be as light and airy after freezing but will still taste delicious.
Reheating
Since this is a no-bake mousse cake, reheating is not recommended. The beauty of this dessert lies in its cool, creamy texture, best enjoyed chilled. If you want warmth alongside, consider serving it with a warm berry compote or sauce on the side.
FAQs
Can I use a different type of cake base?
Absolutely! While sponge cake is preferred for its lightness, you can substitute with genoise or even a ladyfinger base to suit your taste. Just ensure it’s light enough to complement the airy mousse.
Is it possible to make this cake vegan?
To create a vegan version, replace the gelatin with agar-agar and use coconut cream or another non-dairy whipped cream alternative. The berry puree and other ingredients remain the same, preserving that fresh fruit flavor.
What can I substitute if I don’t have gelatin?
Agar-agar powder is a great plant-based substitute for gelatin and can be used in roughly the same quantity. Follow package instructions carefully since it sets differently, but it will still give your mousse a firm, sliceable texture.
Can I prepare this cake in advance for a party?
Definitely! This Berry Layered Mousse Cake Recipe is a fantastic make-ahead dessert that actually benefits from resting time. Make it the day before your event to allow the flavors to meld and the mousse to set perfectly.
How do I prevent the mousse from becoming watery?
Make sure the berry puree has cooled completely before folding it into the whipped cream. Also, do not overbeat your cream or overfold the mixtures as both can cause the mousse to lose its structure and become watery.
Final Thoughts
This Berry Layered Mousse Cake Recipe is a true celebration of fresh berries and creamy decadence, perfect for impressing friends or indulging yourself on a special day.

Ingredients
Berry Puree
- 1 1/2 cups mixed berries (fresh or frozen)
- 1/4 cup granulated sugar
- 2 tablespoons lemon juice
- 2 teaspoons unflavored gelatin
- 2 tablespoons cold water
Mousse
- 1 1/2 cups heavy whipping cream
- 1/4 cup powdered sugar
- 1 teaspoon vanilla extract
Assembly
- 1 prepared sponge cake layer (8 or 9 inches)
- Fresh berries and mint leaves for garnish (optional)
Instructions
- Prepare Berry Puree: In a small saucepan, combine mixed berries, granulated sugar, and lemon juice. Cook over medium heat for 5 to 7 minutes until the berries soften and release their juices. Use a fork or blender to puree the mixture, then strain through a fine sieve to remove seeds for a smooth texture.
- Bloom Gelatin: Sprinkle the unflavored gelatin over cold water in a small bowl and allow it to sit undisturbed for 5 minutes to soften and bloom.
- Dissolve Gelatin: Gently warm the bloomed gelatin mixture until fully dissolved (avoid boiling). Stir the dissolved gelatin thoroughly into the cooled berry puree and set aside to reach room temperature.
- Whip Cream: In a separate bowl, whip the heavy cream with powdered sugar and vanilla extract until medium peaks form—when the cream holds shape but is still soft.
- Combine Mousse: Carefully fold the cooled berry gelatin mixture into the whipped cream until fully incorporated, maintaining the mousse’s fluffy texture.
- Assemble Cake: Place the prepared sponge cake layer in a springform pan or cake ring. Pour the berry mousse over the cake base and smooth the surface evenly with a spatula.
- Chill and Set: Refrigerate the cake for at least 4 hours, or until the mousse is completely set and firm to the touch.
- Serve: Carefully remove the cake from the pan. Garnish with fresh berries and mint leaves if desired before slicing and serving.
Notes
- You can use a store-bought sponge cake layer or bake your own for added freshness.
- For more defined layers, add an additional thin layer of sponge cake in the middle of the mousse.
- Swap mixed berries for a single fruit like raspberry or blueberry for a different flavor profile.
