My Top Tips for Lime Mousse Cheesecake
Make sure your gelatin is completely dissolved and slightly cooled before adding it to the cream cheese or whipped cream. If it's too hot, it will deflate the whipped cream. If it's not dissolved completely, you'll have lumpy spots. The mousse layer needs at least 4 hours to set properly, so plan accordingly. This patience is similar to what we need with our dark chocolate raspberry cheesecake, where proper chilling makes all the difference.
Making Lime Mousse Cheesecake with My Family
Last weekend, Adam helped me make this lime mousse recipe for a family gathering. He was fascinated by watching the gelatin bloom and dissolve. "It's like science, Mom!" he said excitedly. When it came time to zest the limes, he carefully grated them and said, "This smells amazing!"
The next day when we unmolded the finished cheesecake, Adam's jaw dropped. "Look at the two different layers! It's so pretty!" Grandma Viola tried a slice and said, "This no-bake key lime cheesecake has a smooth, creamy, mousse-like filling with a graham cracker crust that's absolutely divine. The lime flavor is so fresh and bright."
Substitutions for Lime Mousse Cheesecake
- Crust: Use buttery shortbread crust or graham cracker crust instead of gingersnap cookie crust for different flavor profiles.
- Limes: Can you use regular limes for key lime cheesecake? Yes! Regular Persian limes work perfectly and are easier to find.
- White chocolate: Omit for a lighter version, though it adds wonderful richness to the white-chocolate lime filling.
- Cream cheese: For philadelphia lime mousse cheesecake, use Philadelphia brand for the creamiest texture.
Variations on Lime Mousse Cheesecake
- Raspberry swirl: Create a raspberry recipes inspired version by swirling raspberry puree through the mousse layer.
- Keto version: Make a keto key lime cheesecake mousse using sugar substitutes and almond flour crust.
- Individual portions: Make cheesecake mousse no bake cups in individual glasses for perfect portions. Check out this key lime cheesecake for more lime inspiration.
Equipment for Lime Mousse Cheesecake

- Electric mixer: Makes whipping cream and beating cream cheese smooth and effortless.

- Offset spatula: Perfect for spreading the mousse layer evenly over the cheesecake.
Storage Tips for Lime Mousse Cheesecake
- Refrigerator: Cover and store for up to 4 days. The mousse stays light and airy throughout.

FAQ about Lime Mousse Cheesecake
What is cheesecake mousse made of?
Cheesecake mousse is made of cream cheese, sugar, flavoring (like lime juice and grated lime zest), unflavored gelatin to help it set, and whipped egg whites or chilled heavy whipping cream folded in to make it light and airy. For this lime mousse cheesecake, we make two layers: a denser cheesecake base and a lighter mousse top. The mousse layer has more whipped cream and less cream cheese, creating that signature cloud-like texture.
What is the difference between cheesecake and cheesecake mousse?
Traditional cheesecake is dense and rich, usually baked with eggs, and has a firm, sliceable texture. Cheesecake mousse is lighter and airier because it includes whipped egg whites or whipped cream and is typically no-bake, set with gelatin. This no bake lime mousse cheesecake combines both textures: a creamy cheesecake layer on bottom and a light tangy key lime mousse on top, giving you the best of both worlds.
Can you use regular limes for key lime cheesecake?
Yes! Regular limes work perfectly for this key lime mousse cheesecake. Key limes are smaller and more aromatic, but Persian limes (the common grocery store variety) have great flavor and are much easier to find. You'll need about 4 to 5 regular limes to get ½ cup juice. The white-chocolate lime filling tastes delicious with either variety, so use what's available.
Can you add cream cheese to mousse?
Absolutely! Adding cream cheese to mousse creates cheesecake mousse, which has more body and tang than traditional mousse. For this best lime mousse cheesecake, the bottom layer has more cream cheese for stability, while the top mousse layer has less cream cheese and more chilled heavy whipping cream for that light, airy texture. The cream cheese adds richness and that signature cheesecake flavor to the dessert.

Now that you've mastered this light and zesty Lime Mousse Cheesecake, you have the perfect dessert for any celebration.
