Key Lime Cheesecake is a classic dessert that blends the rich, velvety texture of baked cheesecake with the distinctive brightness of key lime. Known for their sharp yet aromatic acidity, key limes bring clarity and balance to the creaminess of cream cheese, resulting in a dessert that is both indulgent and refreshing. This combination makes Key Lime Cheesecake especially suitable for formal occasions, seasonal celebrations, and elegant dinner menus.
This recipe is constructed using professional baking principles to ensure consistency, structure, and clean presentation. A crisp graham cracker crust provides a stable base, while a carefully mixed filling delivers a smooth, custard-like interior without cracks or excessive density. Gentle baking and proper chilling are essential steps that allow the flavors to fully develop and the texture to set correctly.
Ingredients

-
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, at room temperature
-
¾ cup sour cream, room temperature
-
½ cup key lime juice
-
1 tablespoon key lime zest
-
1 teaspoon pure vanilla extract

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 securely with two layers of heavy-duty aluminum foil to protect it during the water bath.
2. Make the Graham Cracker Crust
In a medium bowl, combine the graham cracker crumbs, sugar, and salt. Add the melted butter and stir until the mixture is evenly moistened. Press firmly into the bottom of the prepared pan, creating an even and compact layer.
Bake the crust for 10 minutes, then remove from the oven and allow it to cool slightly.
3. Mix the Cream Cheese
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 bowl as needed to ensure uniform texture.
4. Add Sugar and Salt
Add the granulated sugar and salt, mixing on medium-low speed until fully incorporated. The mixture should appear smooth and creamy.
5. Incorporate the Eggs
Add the eggs one at a time, mixing on low speed after each addition just until blended. Avoid overmixing to prevent excess air from entering the batter.
6. Finish the Filling
Add the sour cream, key lime juice, key lime zest, and vanilla extract. Mix on low speed until the batter is smooth and cohesive.
7. Assemble and Prepare the Water Bath
Pour the filling over the cooled crust and smooth the surface. Place the springform pan inside a large roasting pan. Carefully add hot water to 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 surface should appear glossy but not liquid.
9. Cool Gradually
Turn off the oven and leave the door slightly ajar. Allow the cheesecake to cool in the oven for 1 hour. Remove from the oven, discard the foil, and let cool completely at room temperature.
10. Chill
Refrigerate the cheesecake for at least 6 hours, preferably overnight, before slicing and serving.
