Creamy No-Bake Key Lime Cheesecake – A Bright & Zesty Slice of Sunshine

---

A Cheesecake That Tastes Like Summer

Imagine the first bite: cool, creamy cheesecake with a tangy burst of fresh key lime, nestled on a buttery graham cracker crust. The citrus hits your tongue first, tart but sweet — like a gentle ocean breeze on a Florida afternoon. Then comes the silkiness of the cream cheese, lush and smooth, melting in your mouth like sunshine on a warm plate.

This Key Lime Cheesecake is my go-to when I want something light, zesty, and crowd-pleasing. It’s a little tropical, a little indulgent, and absolutely no-bake. I first made this dessert after a trip to Key West — every café there had their own version, and I couldn’t leave without recreating that flavor at home. One slice and you’ll understand why I had to.

Whether it’s for a dinner party or a Sunday treat, this cheesecake has that “wow” factor without any fuss. No oven. No water bath. No stress.

Step-by-Step Instructions

Step 1: Make the Crust

• In a bowl, mix graham cracker crumbs, sugar, and melted butter.
• Stir until mixture resembles wet sand and presses together easily.
• Press into the bottom of a 9-inch springform pan, creating a smooth, even base.
• Use the back of a spoon or bottom of a glass to firmly compact the crust.
• Chill in the freezer while you make the filling.

💡 Pro Tip: A well-packed crust prevents crumbling when slicing!

---

Step 2: Whip Up the Filling

• In a large bowl, beat cream cheese until light and fluffy (about 2–3 minutes).
• Slowly add in the sweetened condensed milk, beating on low until smooth.
• Add lime juice, zest, and vanilla extract.
• Beat just until fully combined and creamy.

👃 Sensory Check: The mixture should smell fresh and citrusy, with no lumps.

---

Step 3: Pour and Chill

• Pour the filling over the chilled crust, smoothing the top with a spatula.
• Tap the pan gently to remove any air bubbles.
• Cover with foil or plastic wrap and chill at least 6 hours, preferably overnight.

❄️ No shortcuts here—this step sets the cheesecake properly without baking.

Step 4: Make the Whipped Topping (Optional)

• In a cold bowl, whip heavy cream, powdered sugar, and vanilla until soft peaks form.
• Spread or pipe over the set cheesecake just before serving.

🌀 Want extra flair? Pipe it in rosettes and top with a sprinkle of zest.
