This blueberry mousse cheesecake combines the rich creaminess of a traditional cheesecake with the light fluffiness of a blueberry mousse for a show-stopping dessert. The vibrant purple-blue top layer creates a beautiful contrast against the creamy white cheesecake filling, making it as gorgeous as it is delicious.
I first made this for my sister's birthday when she requested something with blueberries, and it was such a hit that it's become my go-to dessert whenever I need to impress someone without spending hours in the kitchen.
Ingredients
- Graham cracker crumbs: Provide the perfect crunchy base with a hint of honey flavor
- Cream cheese: Should be fully softened to room temperature for the smoothest texture
- Fresh blueberries: Work best in summer but frozen berries allow you to make this year round
- Lemon juice: Brightens the blueberry flavor and balances the sweetness
- Heavy whipping cream: Must be very cold to whip properly for both layers
- Gelatin: Optional but helps create a more stable mousse especially in warmer weather
Step-by-Step Instructions
- Prepare the crust:
- Combine the graham cracker crumbs, melted butter, and sugar in a bowl and mix until it resembles wet sand. The mixture should hold together when pressed between your fingers. Press firmly into the bottom of a springform pan using the bottom of a measuring cup to create an even layer. Place in refrigerator to firm up for at least 15 minutes.
- Create the cheesecake layer:
- Beat the cream cheese in a large bowl until completely smooth with no lumps remaining, about 2 minutes. Add the sugar and vanilla, continuing to beat until well incorporated and the mixture is light and fluffy. In a separate bowl, whip the cold heavy cream until stiff peaks form when you lift the beater. Gently fold the whipped cream into the cream cheese mixture using a spatula with a light hand to maintain as much air as possible. Spread this mixture evenly over the chilled crust.
- Prepare the blueberry mousse:
- Cook the blueberries with sugar and lemon juice in a saucepan until they burst and release their juices, creating a vibrant purple mixture. The blueberries should be soft enough to mash easily against the side of the pan. Allow this mixture to cool completely before proceeding to avoid melting the whipped cream. Whip the heavy cream until stiff peaks form, then gently fold in the cooled blueberry mixture until fully incorporated but still light and airy.
- Assemble and chill:
- Spread the blueberry mousse over the set cheesecake layer, creating decorative swirls if desired. Cover the springform pan loosely with plastic wrap and refrigerate for at least 4 hours or preferably overnight. The longer it chills, the more the flavors will meld together and the more firmly the layers will set.

The secret to this dessert is taking your time with the folding process. My grandmother taught me to fold whipped cream using a rubber spatula with gentle sweeping motions rather than stirring, which keeps the air bubbles intact and results in the lightest, fluffiest mousse imaginable.
Make Ahead and Storage Tips
This cheesecake actually improves with time in the refrigerator, making it perfect for preparing a day or two before serving. The flavors meld together beautifully as it sits. Store leftovers in the refrigerator for up to 4 days, keeping the springform ring on until serving time for the neatest presentation. You can also freeze individual slices wrapped tightly in plastic wrap for up to a month.
Seasonal Variations
While this recipe shines with summer blueberries, you can adapt it for any season. In fall, try a pumpkin mousse layer with warm spices. Winter calls for a chocolate mousse version with peppermint extract. Spring might feature a strawberry or rhubarb mousse for a tart contrast. The basic format works beautifully with endless flavor combinations to match seasonal produce and holidays.

Serving Suggestions
Serve slices with additional fresh blueberries scattered around the plate for a beautiful presentation. A dollop of lightly sweetened whipped cream on the side provides a nice contrast, while a sprig of fresh mint adds a pop of color. For special occasions, dust the top with a light sprinkle of powdered sugar just before serving or add a drizzle of white chocolate for extra decadence.
Troubleshooting Tips
If your mousse isn't setting properly, the blueberry mixture might have been too warm when folded into the cream. Place the assembled cake in the freezer for 30 minutes before returning to the refrigerator. For clean slices, dip your knife in hot water and wipe dry between cuts. If your crust is crumbly, it might need more butter or firmer packing into the pan.
Frequently Asked Questions
- → Can I use frozen blueberries instead of fresh?
Yes, frozen blueberries work just as well. Just make sure to thaw them before cooking to release their juices properly.
- → Can I skip the gelatin in the mousse?
Yes, the mousse will still work without gelatin, but it may be slightly softer. Using gelatin helps create a firmer texture.
- → Do I need a springform pan for this dish?
A springform pan is ideal for easy removal and clean edges; however, a pie dish can also work if you serve directly from it.
- → How long does it take for the cheesecake to chill?
The cheesecake layer needs at least 2 hours to set in the fridge, and the entire dish should chill for an additional 2-3 hours after adding the mousse.
- → Can I substitute the graham cracker crust?
Absolutely! You can use crushed digestive biscuits, cookie crumbs, or even a chocolate cookie crust to vary the flavor profile.
