🍋 What Is Lime Mousse Cheesecake?
Lime Mousse Cheesecake is a no-bake (or partially baked) dessert that combines the structure of cheesecake with the airy lightness of mousse. The bottom is typically a graham cracker crust, followed by a cream cheese filling that’s folded with lime curd or zest, whipped cream, and sometimes gelatin for stability.
It delivers a silky texture, vibrant citrus flavor, and a cool, refreshing finish — perfect for warm weather or anytime you want something light yet indulgent.
🛒 Ingredients You’ll Need

- 1½ cups graham cracker crumbs
- ¼ cup sugar
- 6 tablespoons melted butter
For the Cheesecake Filling:

For the Lime Mousse Layer:

👩🍳 How to Make Lime Mousse Cheesecake
Step 1: Prepare the Crust
Mix graham crumbs, sugar, and melted butter. Press into the bottom of a springform pan. Bake at 350°F (175°C) for 8 minutes, or chill for no-bake version.
Step 2: Make the Cheesecake Layer
Beat cream cheese until smooth. Add powdered sugar, lime juice, zest, and vanilla. Mix until creamy. Set aside.
Step 3: Make the Lime Mousse
Whip heavy cream with sugar until stiff peaks form. (If using gelatin, bloom it in warm water, melt, and mix into cream cheese filling before folding in whipped cream.) Gently fold whipped cream into the cream cheese mixture.
Step 4: Assemble and Chill
Spread the mousse layer evenly over the crust. Smooth the top and refrigerate for at least 4–6 hours, or overnight for best texture.
