Key Lime Cheesecake is a refined dessert that combines the richness of traditional baked cheesecake with the bright, citrus-forward character of key limes. Known for their distinctive floral acidity, key limes provide a sharper, more aromatic flavor than standard limes, creating a dessert that is indulgent yet refreshing. This balance makes Key Lime Cheesecake an excellent choice for both formal occasions and everyday entertaining.
This recipe is developed with professional technique in mind, ensuring a smooth texture, clean slices, and consistent results. A buttery graham cracker crust anchors the dessert, while a carefully mixed cream cheese filling delivers a creamy mouthfeel without heaviness. Gentle baking and proper cooling are essential steps that allow the cheesecake to set correctly and develop its full flavor.
Ingredients
Graham Cracker Crust
-
1 ¾ cups graham cracker crumbs
-
3 tablespoons granulated sugar
-
½ teaspoon fine salt
-
6 tablespoons unsalted butter, melted
Key Lime Cheesecake Filling
-
24 ounces full-fat cream cheese, softened
-
1 cup granulated sugar
-
¼ teaspoon fine salt
-
3 large eggs, room temperature
-
¾ cup sour cream, room temperature
-
½ cup key lime juice
-
1 tablespoon key lime zest
-
1 teaspoon pure vanilla extract
Optional Garnish
-
Lightly sweetened whipped cream

Fresh lime zest or thin lime slices
Step-by-Step Instructions
1. Prepare the Oven and Pan
Preheat the oven to 325°F. Lightly grease a 9-inch springform pan. Wrap the outside of the pan tightly with two layers of heavy-duty aluminum foil to prevent water from entering during baking.
2. Prepare the Crust
In a medium bowl, combine graham cracker crumbs, sugar, and salt. Stir in melted butter until evenly moistened. Press the mixture firmly into the bottom of the prepared pan, creating an even layer.
Bake for 10 minutes, then remove from the oven and allow to cool slightly.
3. Mix the Cream Cheese Base
In a large mixing bowl, beat the softened cream cheese on medium speed until smooth and free of lumps, approximately 2 minutes. Scrape down the sides of the bowl as needed.
4. Add Sugar and Salt
Add the granulated sugar and salt, mixing on medium-low speed until fully incorporated and smooth.
5. Incorporate the Eggs
Add the eggs one at a time, mixing on low speed after each addition. Mix only until blended to avoid incorporating excess air.
6. Finish the Filling
Add sour cream, key lime juice, key lime zest, and vanilla extract. Mix on low speed until the batter is smooth and uniform.
7. Assemble and Prepare Water Bath
Pour the filling over the cooled crust and smooth the surface. Place the springform pan inside a large roasting pan. Carefully pour hot water into the roasting pan until it reaches halfway up the sides of the cheesecake pan.
8. Bake
Bake for 60–70 minutes, or until the edges are set and the center jiggles slightly when gently shaken. The cheesecake should appear glossy but not liquid in the center.
9. Cool Gradually
Turn off the oven and crack the door open slightly. Allow the cheesecake to cool in the oven for 1 hour. Remove from the oven, discard the foil, and cool completely at room temperature.
10. Chill
Refrigerate for at least 6 hours, preferably overnight, before slicing and serving.
