Lime Mousse Cheesecake

There’s something undeniably special about summer desserts. They bring with them a certain kind of nostalgia—like a breeze through a screened porch or laughter echoing over clinking glasses at family barbecues. One of those cherished, sun-kissed desserts that always manages to steal the show is Lime Mousse Cheesecake.

My first encounter with this silky, citrusy delight was during a family reunion in late June, where the tang of fresh lime contrasted beautifully with the warm, sticky air. Set against a crumbly graham cracker base and topped with whipped cream and lime zest, it was love at first bite. Unlike traditional dense cheesecakes, this version is light, almost cloud-like, with just the right balance of tangy and sweet. And best of all—it’s no-bake. That means you can enjoy this treat without heating up your kitchen.

Beyond its ease and elegance, this dessert also holds a sense of tradition. It’s the kind of recipe passed down in handwritten notes, tweaked by generations, and perfected over time. Each slice carries memories of birthdays, picnics, and porch-side chats. Whether it’s a holiday, a weekend celebration, or simply a craving for something fresh and indulgent, Lime Mousse Cheesecake never disappoints.

How to Make Lime Mousse Cheesecake

STEP-BY-STEP INSTRUCTIONS:

Step 1: Build the Crust

Start by mixing graham cracker crumbs, granulated sugar, and melted butter in a bowl until it resembles wet sand. Press this mixture into the bottom of a 9-inch springform pan. Use the back of a spoon or the bottom of a glass to create a smooth, even layer. Pop it into the fridge while you prepare the mousse.

Step 2: Bloom the Gelatin

Sprinkle the gelatin over cold water in a small bowl and let it sit for 5 minutes. Then microwave it for 15–20 seconds until fully dissolved. Stir and let it cool slightly—just enough so it blends smoothly later.

Step 3: Whip Up the Filling

In a large mixing bowl, beat the softened cream cheese and powdered sugar until silky smooth. Add lime juice, zest, and vanilla extract. The citrus aroma will instantly brighten your kitchen. In another bowl, whip the heavy cream until it forms stiff peaks.

Step 4: Bring It All Together

Stir the cooled gelatin into the cream cheese mixture. Then, gently fold in the whipped cream. Take your time with this step—you want to keep the mousse airy and light.

Step 5: Chill and Set

Pour the lime mousse over your chilled crust. Smooth out the top with a spatula. Refrigerate for at least 4 hours, though overnight is ideal. The mousse will firm up beautifully, creating clean, creamy slices.

Step 6: Garnish and Serve

When ready to serve, garnish with lime slices or a bit of zest. A dollop of whipped cream adds the final touch. Serve chilled for that perfect creamy bite with a citrus zing.

Helpful Tips

• Room Temp Cream Cheese: This ensures the filling turns out silky and lump-free.
• Don’t Skip the Chill Time: It’s essential for the mousse to set fully.
