This silky raspberry mousse transforms ordinary berries into an elegant dessert that tastes like summer in every spoonful. The perfect balance of tart raspberries and sweet cream creates a light yet decadent treat that never fails to impress dinner guests.
I first made this raspberry mousse for my daughter's birthday when she requested something "pink and fancy." Now it has become our signature dessert for celebrations big and small, earning rave reviews every time.
Ingredients
- Fresh or frozen raspberries: Bring intense berry flavor and vibrant color. Frozen work perfectly when berries are out of season.
- Granulated sugar: Balances the tartness of the berries without overpowering them.
- Fresh lemon juice: Brightens the flavor and enhances the natural berry taste.
- Powdered gelatin: Provides the perfect airy-yet-stable texture. Knox brand is reliable and widely available.
- Heavy whipping cream: At least 36% fat content whips up best for the fluffiest mousse.
- Powdered sugar: Dissolves instantly in cream and helps stabilize the whipped texture.
- Fresh raspberries for garnish: Add visual appeal and a hint of what's inside.
Step-by-Step Instructions
- Bloom the Gelatin:
- Pour 3 tablespoons cold water into a small bowl and sprinkle the gelatin evenly over the surface. Let it sit undisturbed for 5-10 minutes until it absorbs the liquid and becomes translucent and gel-like. This essential step ensures the gelatin dissolves properly later without forming lumps.
- Prepare the Raspberry Base:
- Combine raspberries, granulated sugar, and lemon juice in a medium saucepan over low heat. Cook gently while stirring frequently until sugar completely dissolves and berries release their juices. Avoid boiling as high heat can affect the flavor. Press this mixture through a fine mesh strainer using the back of a spoon to remove all seeds for a perfectly smooth mousse.
- Incorporate the Gelatin:
- Return the strained raspberry mixture to the saucepan and add the bloomed gelatin. Warm over low heat while stirring constantly just until the gelatin completely dissolves. You'll know it's ready when no clear specks remain. Transfer to a large clean bowl and allow to cool until just barely warm to the touch, about 10-15 minutes. The mixture should flow freely but not be hot enough to deflate the whipped cream.
- Whip the Cream:
- In a large mixing bowl, combine heavy cream and powdered sugar. Begin beating at low speed to prevent splattering, then increase to medium speed once the cream starts to thicken. Whip until stiff peaks form that stand upright when the beaters are lifted. Be careful not to overwhip or the cream will become grainy and butter-like.
- Create the Mousse:
- Add about one quarter of your whipped cream to the raspberry mixture and fold gently until incorporated. This lightens the berry base making it easier to fold in the remaining cream. Add the remaining whipped cream in two additions, using a rubber spatula to cut down through the center and fold the mixture over itself with a gentle turning motion until no white streaks remain.
- Portion and Chill:
- Carefully spoon or pipe the mousse into individual serving dishes. For the most elegant presentation, use clear glasses to showcase the beautiful pink color. Cover each with plastic wrap and refrigerate for at least 2 hours or up to 24 hours until the mousse is completely set.

This raspberry mousse holds a special place in my heart because it reminds me of picking fresh berries with my grandmother in summer. She taught me that straining the seeds takes extra time but makes all the difference in creating that velvety smooth texture that elevates a simple dessert to something truly special.
Make-Ahead Magic
The beauty of this raspberry mousse lies in its ability to be prepared up to two days in advance. The mousse actually improves with time as the flavors meld and develop. Simply cover each serving dish tightly with plastic wrap, ensuring the wrap doesn't touch the surface to prevent a skin from forming. Remove from refrigeration about 10 minutes before serving to allow the mousse to reach the perfect temperature for the most intense flavor experience.
Flavor Variations
While raspberries create the classic version of this mousse, the recipe works beautifully with other berries or combinations. Try blackberries for a deeper, more intense flavor, strawberries for a sweeter profile, or a mixed berry blend for complexity. You can also add complementary flavors like 1 teaspoon of rosewater with raspberries, a tablespoon of orange zest with strawberries, or a splash of Grand Marnier for an adult version. The basic technique remains the same regardless of which fruit you choose.
Elegant Presentation Ideas
Transform this simple dessert into a showstopper with thoughtful presentation. Layer the mousse in clear glasses with fresh berries or crumbled shortbread for textural contrast. For dinner parties, serve in martini glasses with a mint leaf and a single perfect raspberry. Create a dessert bar by offering the mousse in small cups with various toppings like chocolate shavings, crushed meringues, or toasted nuts. For special occasions, pipe the mousse into chocolate cups for an edible vessel that delights guests.

Frequently Asked Questions
- → Can I use frozen raspberries for this mousse?
Yes, you can absolutely use frozen raspberries. Just make sure to thaw them completely before using and drain any excess liquid to prevent the mousse from becoming too watery.
- → How far in advance can I make this raspberry mousse?
You can prepare this mousse up to 2 days in advance. Keep it covered in the refrigerator to prevent it from absorbing other food odors. Add the fresh garnishes just before serving for the best presentation.
- → Can I make this mousse without gelatin?
For a vegetarian version, you can substitute the gelatin with agar-agar powder (use about 1 tablespoon) or 2 tablespoons of cornstarch mixed with a little cold water. The texture will be slightly different but still delicious.
- → Why is my raspberry mousse not setting properly?
If your mousse isn't setting, the most common reasons are: the gelatin wasn't properly bloomed, the mixture was too hot when you added the whipped cream (melting it), or it needs more time in the refrigerator. Make sure to follow the gelatin instructions carefully and allow at least 2-3 hours of chilling time.
- → Can I use other berries instead of raspberries?
Yes, this mousse works beautifully with strawberries, blackberries, or a mixed berry combination. Just keep the same quantities and strain the seeds if desired. Each berry will provide its own unique flavor profile.
- → How can I make the mousse less sweet?
To reduce sweetness, decrease the granulated sugar to 1/3 cup and reduce the powdered sugar in the whipped cream to 2 tablespoons. Taste your berries first - if they're particularly tart, you might want to keep the original sugar amounts.
