Ingredients
- 2 cups fresh raspberries (plus extra for garnish): The fresher, the better! Look for plump, juicy raspberries at your local farmer’s market.
- 1/2 cup granulated sugar: Adjust to your sweetness preference. I sometimes use a little less, depending on the tartness of the raspberries.
- 2 tablespoons lemon juice: This brightens the flavor and balances the sweetness.
- 1 tablespoon unflavored gelatin: This is what gives the mousse its lovely, light texture. Make sure it’s unflavored, or you’ll end up with a weird taste!
- 3 tablespoons cold water: Use really cold water for best gelatin blooming.
- 1 1/2 cups heavy whipping cream: The key to a luscious, airy mousse! Make sure it’s very cold.
- 1 teaspoon vanilla extract: A touch of vanilla enhances the raspberry flavor beautifully.
- Fresh mint leaves for garnish (optional): A pop of color and freshness.

How to Make It
Let’s get cooking! It’s easier than you think.
- First, you’ll puree the raspberries. I use an immersion blender, but a regular blender works great too.
- Next, strain the puree through a fine-mesh sieve to remove the seeds. This step is optional, but it makes for a smoother mousse.
- In a small saucepan, combine the raspberry puree, sugar, and lemon juice. Heat over medium-low heat, stirring until the sugar is completely dissolved.
- In a small bowl, sprinkle the gelatin over the cold water. Let it sit for about 5 minutes to “bloom,” which means it absorbs the water and gets ready to thicken.
- Stir the bloomed gelatin into the warm raspberry mixture until it’s completely dissolved. Let it cool slightly.
- In a large bowl, whip the heavy cream and vanilla extract until you get soft peaks. Don’t overwhip or it will become grainy!
- Gently fold the cooled raspberry mixture into the whipped cream. Be careful not to deflate the cream!
- Spoon the mousse into individual serving dishes or a larger bowl. Cover and refrigerate for at least 2-3 hours, or until set.
- Just before serving, garnish with fresh raspberries and mint leaves (if using).
Substitutions & Additions
Feel free to experiment! You could use frozen raspberries (thawed and drained), or add a tablespoon of raspberry liqueur for an extra kick (for the adults only, of course!). A swirl of chocolate sauce would also be delicious!
Tips for Success
- Make sure your cream and bowl are very cold when whipping the cream. This helps achieve stiff peaks.
- Don’t overwhip the cream! Once you see soft peaks, stop whipping.
- Fold the raspberry mixture into the whipped cream gently using a spatula. This preserves the airiness of the whipped cream.
- You can prepare the raspberry mixture ahead of time and store it in the refrigerator until ready to fold into the whipped cream.
How to Store It
Store leftover mousse in an airtight container in the refrigerator for up to 3 days. It’s best enjoyed within the first two days though, for optimal texture and flavor.
FAQs
- Q: Can I use a different type of berry? A: Absolutely! Strawberries, blueberries, or a mixed berry puree would all work wonderfully.
- Q: What if my mousse doesn’t set? A: Make sure your gelatin was fully bloomed and dissolved, and that your cream was properly whipped. It may also need a little longer in the fridge to set fully.
- Q: Can I make this ahead of time? A: Yes! You can make the mousse a day or two in advance and keep it refrigerated until ready to serve.
- Q: Is this mousse gluten-free? A: Yes, this recipe is naturally gluten-free.
