🥣 Instructions
1. Make the Crust (Optional):
- In a bowl, combine graham cracker crumbs and sugar. Stir in melted butter until well blended.
- Divide the mixture evenly among 8–10 small dessert cups. Press gently into an even layer. Set aside.
2. Prepare the Gelatin:
- In a small bowl, mix lemon juice and water. Sprinkle gelatin over the top and let stand for 5 minutes to bloom.
- Microwave the gelatin mixture for 30 seconds. Stir well until fully dissolved. Cool for 3 minutes.
3. Whip the Cream:
- In a medium bowl, beat heavy cream with ⅓ cup of powdered sugar until soft peaks form.
- Add a drop of yellow food coloring if desired, then continue whipping until stiff peaks form.
4. Make the Lemon Cheesecake Base:
- In a separate large bowl, beat cream cheese until smooth.
- Mix in lemon curd and remaining ⅔ cup powdered sugar until creamy.
- With the mixer running, slowly add the cooled gelatin mixture and blend until smooth.
5. Fold Everything Together:
- Gently fold ⅓ of the whipped cream into the lemon cheesecake mixture to lighten it.
- Add the remaining whipped cream and fold in gently until fully combined.
6. Assemble & Chill:
- Spoon or pipe the mousse into your prepared dessert cups over the crust layer.
- Cover and refrigerate for at least 2 hours, or up to 1 day ahead.
- Garnish before serving with whipped cream, lemon wedges, berries, or mint if desired.
✅ Tips for Success:
- Don’t skip blooming the gelatin: It gives the mousse its structure without being rubbery.
- Room temperature cream cheese ensures a smooth, lump-free mixture.
- Customize the base: Skip the crust or use crushed cookies for a fun twist.

🍋 FAQs
Can I omit the gelatin?
Yes, but the mousse will be softer and may not hold its shape as well. You can try using agar-agar or reduce the lemon juice slightly to compensate.
Can I use store-bought lemon curd?
Absolutely! This recipe was tested with Dickenson’s, but you can use any high-quality lemon curd. Taste and adjust sweetness as needed.
Can I make a lighter version?
Try low-fat cream cheese and light whipped topping, and reduce sugar to taste. It’ll still be creamy and flavorful!
What’s the difference between this and lemon cheesecake?
This mousse has the flavor of cheesecake but is much lighter and fluffier — and it sets in the fridge instead of baking.
