Key lime cheesecake bars are the tangy, sweet treat that brighten up a dessert table for any occasion. Cut larger pieces of these cheesecake bars for plated service (with plenty of whipped cream ), or cut smaller ones for grab-and-go bites, perfect for a party—no plate required.
Key Lime Cheesecake Bars Ingredients
All ingredients for these Key lime cheesecake bars are widely available and easy to find at the grocery store.
To make the white-chocolate graham cracker crust, you will need graham cracker crumbs, unsalted butter, sugar, white chocolate, salt, allspice, nutmeg, and cooking spray.
For the cheesecake filling, you’ll need cream cheese, sour cream, butter, sugar, salt, eggs, Key lime juice (either fresh or bottled), and Key lime zest.
For decoration and serving, you’ll also need Key lime slices and lightly sweetened whipped cream.
What Do Key Lime Cheesecake Bars Taste Like?
This dessert is super creamy with a tangy zing. The sweetness of the white chocolate in the crust balances the bite of the lime juice in the filling, which is bright and zesty. The Key lime flavor really shines through.
The warm spices in the crust provide a perfect complement with the tangy filling; the white chocolate is subtle but it helps make this crust taste elevated and unique.
How To Serve Key Lime Cheesecake Bars
When cut into 12 pieces, these bars are substantial in size—just right to serve topped with whipped cream as a plated dessert for a seated group.
If cut smaller, this recipe will yield more pieces and work better as a finger-food, grab-and-go-style dessert option.
For another creative serving suggestion (and a delicious way to use any leftovers), cut cheesecake into small cubes, freeze them, and use the sweet pieces as a topping on your favorite ice cream flavor.
Key Lime Cheesecake Bars Recipe Tips
- You can use fresh Key limes for juice in this recipe. But bottled Key lime juice works just fine too (and it’s much faster than squeezing tiny Key limes to make enough juice).
- Plus, Key lime juice is also available year round and a great solution when fresh Key limes aren’t available. Regular lime juice and zest also works in this recipe if Key limes are not available.
- Try using a water bath when baking to help stop the cheesecake from cracking and to promote even baking.
- When you’re ready to cut, get the cleanest slices each time by heating your knife under hot running water then wiping it dry. Repeat this step between every slice for the best results.
Can You Freeze Key Lime Cheesecake Bars?
These tangy and sweet bars freeze well (if there’s anything left over!). Just wrap them in plastic, and place them in a zip-locking bag. They’ll last up to a month in the freezer.

Stir together graham cracker crumbs, butter, sugar, white chocolate, salt, allspice, and nutmeg in a large bowl until combined and evenly moistened.

Beat cream cheese, sour cream, and butter in a stand mixer fitted with the paddle attachment on medium speed until fluffy and fully combined, 4 to 5 minutes.
