Ingredients

This blackberry mousse keeps things simple with just a handful of fresh, flavorful ingredients. Make sure your blackberries are ripe and sweet for the best results!

You’ll need:

2 cups fresh blackberries (plus a few extra for garnish)
1/2 cup granulated sugar
1 teaspoon lemon juice
1 teaspoon vanilla extract
1 cup heavy whipping cream
1 tablespoon powdered sugar (optional, for extra sweetness)
Fresh mint leaves (optional, for garnish)

Instructions

This blackberry mousse comes together in just a few easy steps. No baking, no gelatin—just fresh fruit and a bit of magic from your mixer!

Step-by-step:

Make the Blackberry Puree
In a saucepan over medium heat, combine the blackberries, granulated sugar, and lemon juice. Cook for about 5–7 minutes, stirring occasionally, until the berries break down and the mixture thickens slightly.
Blend and Strain
Remove from heat and let it cool for a few minutes. Then blend until smooth using a blender or food processor. Strain through a fine mesh sieve to remove seeds. Set aside to cool completely.
Whip the Cream
In a large bowl, whip the heavy cream and powdered sugar (if using) until soft peaks form. Add vanilla extract and gently mix.
Fold in the Blackberry Puree
Once the blackberry mixture is cool, gently fold it into the whipped cream until fully combined and smooth. Be careful not to deflate the cream too much.
Chill and Serve
Spoon the mousse into serving glasses or jars. Refrigerate for at least 2 hours to set. Top with fresh blackberries and mint leaves before serving.

Tips and Variations

Want to make this mousse your own? Here are some easy ways to switch it up or elevate the flavor:

Frozen Berries Work Too: No fresh blackberries? Frozen ones are totally fine—just thaw before using.
Make it Vegan: Swap out the heavy cream for coconut cream and use a plant-based sweetener.
Add a Crunch: Layer with crushed graham crackers or shortbread cookies for texture.
Citrus Twist: Add a bit of orange zest for a refreshing zing.
Chocolate Drizzle: A touch of melted dark chocolate on top takes it to the next level.
Berry Mix: Combine blackberries with raspberries or blueberries for a colorful berry blend.

Storage

If you have leftovers (lucky you!), this mousse stores beautifully.

Refrigerator: Cover the glasses or containers with plastic wrap or transfer mousse to an airtight container. Store in the fridge for up to 3 days.
Freezing Not Recommended: Freezing can change the mousse’s creamy texture, so it’s best enjoyed fresh or chilled.

Frequently Asked Questions

1. Can I use frozen blackberries?
Yes! Just make sure to thaw and drain them before using to avoid excess moisture.

2. Do I need gelatin for this mousse?
Nope! This recipe gets its light, fluffy texture from whipped cream—no gelatin required.

3. Can I make this ahead of time?
Absolutely. It’s actually best made a few hours ahead so it has time to chill and set.

4. How can I make this dairy-free?
Use chilled coconut cream in place of heavy cream for a vegan-friendly version.

5. Can I reduce the sugar?
Yes. Taste your blackberry puree before mixing, and feel free to adjust the sugar to your liking.

6. What can I serve it with?
Pair it with shortbread cookies, a drizzle of chocolate, or a few extra fresh berries.

7. Can I blend the berries without cooking them?
You can, but cooking enhances the flavor and helps the sugar dissolve better. Plus, it makes straining easier.
