Key Lime Cheesecake Bars Recipe (Creamy & Easy)
Key Lime Cheesecake Bars are creamy, bright, and easy to make. These tangy dessert bars combine a buttery graham cracker crust with a smooth lime cheesecake filling, so they are perfect for serving 4–6 people.
Why This Key Lime Cheesecake Bars Recipe Works
First, the graham cracker crust adds a crisp, buttery contrast to the creamy filling. Next, fresh key lime juice brings a lively citrus flavor without making the bars overly sweet. Finally, a short chill helps the cheesecake set neatly, making each bar easy to slice and serve.
Ingredients
For the crust
- 1 cup graham cracker crumbs
- 3 tablespoons unsalted butter, melted
- 2 tablespoons granulated sugar
For the cheesecake filling
- 8 ounces cream cheese, softened
- 1/3 cup granulated sugar
- 1 large egg
- 1/4 cup key lime juice
- 1 teaspoon finely grated key lime zest
- 1/2 teaspoon vanilla extract
For serving
- Whipped cream, optional
- Extra lime zest, optional
Step-by-Step Instructions
- Preheat the oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving some overhang for lifting.
- Combine the graham cracker crumbs, melted butter, and sugar. Press the mixture firmly into the pan, then bake for 8 minutes.
- Meanwhile, beat the softened cream cheese and sugar until smooth. Add the egg, key lime juice, lime zest, and vanilla, then mix just until combined.
- Pour the filling over the warm crust. Smooth the top, and bake for 20–24 minutes, or until the edges are set and the center has a slight jiggle.
- Cool the bars completely at room temperature. Then, refrigerate them for at least 2 hours.
- Lift the chilled cheesecake from the pan, slice into 4–6 bars, and garnish with whipped cream or lime zest before serving.

Pro Tips for Key Lime Cheesecake Bars
- Use room-temperature cream cheese for a smoother filling.
- Do not over-mix after adding the egg, because excess air can cause cracks.
- For cleaner slices, chill the bars fully and wipe the knife between cuts.
- If key limes are unavailable, regular limes work well; however, the flavor may be slightly less floral.
Storage Instructions
Store the bars in an airtight container in the refrigerator for up to 4 days. Alternatively, freeze un-garnished bars for up to 2 months. Thaw them overnight in the refrigerator before serving.
FAQ
Can I use regular lime juice?
Yes. Regular lime juice is a convenient substitute and still gives the bars a fresh, tangy flavor.
How do I know when the cheesecake bars are done?
The edges should look set, while the center should gently jiggle when the pan is moved. The filling will firm as it cools.
Can I make these bars ahead of time?
Absolutely. Prepare them a day ahead, keep them covered in the refrigerator, and add garnishes just before serving.
Why did my cheesecake crack?
Cracks can happen when the bars are over-baked or the filling is over-mixed. Even so, whipped cream and lime zest make an easy finishing touch.
