Main Ingredients

For the Crust:

  • 2 cups graham cracker crumbs
  • 1/2 cup unsalted butter, melted
  • 2 tablespoons granulated sugar
  • 1/4 teaspoon kosher salt
  • Nonstick cooking spray

For the Filling:

  • Four 8-ounce packages cream cheese, room temperature
  • 1/2 cup sour cream, room temperature
  • 1 1/4 cups granulated sugar
  • 2 tablespoons all-purpose flour
  • 1/2 teaspoon kosher salt
  • 4 large eggs, room temperature
  • 1 tablespoon vanilla extract
  • 2 teaspoons key lime or lime zest
  • 1/3 cup key lime juice (fresh or bottled)

For the Topping:

  • 3/4 cup heavy whipping cream
  • 3 tablespoons granulated sugar
  • 1/2 teaspoon vanilla extract
  • Key lime zest or lime zest, for garnish
  • Key lime slices, for garnish

Step-by-Step Instructions

1. Prepare the Crust

Preheat your oven to 325°F. Grease a 9-inch springform pan lightly with nonstick spray, then wrap heavy-duty foil around the bottom and sides to guard against leaks. (A tight seal helps keep the water bath from seeping in during baking.)

  • Mix graham cracker crumbs, melted butter, sugar, and salt together until even and press the mixture firmly into the bottom and about 1 inch up the sides of the pan.
  • Bake the crust for 10–12 minutes, until golden brown. Cool completely on a wire rack—about 30 minutes.

2. Prepare the Water Bath

Bring a large pot of water to a simmer on the stovetop. You’ll pour this into a roasting pan to create steam and ensure a tender, crack-free texture for your cheesecake.

3. Make the Cheesecake Filling

  • In a stand mixer with the paddle attachment, beat the cream cheese on medium speed until completely smooth (about 2 minutes).
  • Add sour cream, sugar, flour, and salt, beating until creamy and smooth.
  • Scrape down the bowl, then add eggs one by one, mixing on low speed just until incorporated.
  • Stir in vanilla, key lime zest, and key lime juice. (For extra flavor, use both zest and juice.)

4. Bake the Cheesecake

  • Pour the smooth lime filling into the cooled crust and tap the pan gently to release bubbles.
  • Set the springform pan inside a deep roasting pan. Carefully pour the simmering water into the outer pan (not inside the cheesecake) until it comes halfway up the sides.
  • Bake at 325°F for 70–80 minutes, until the edges are set but the center still jiggles slightly.
  • Turn off the oven and crack the oven door. Leave the cheesecake inside for 1 hour—a slow cooling process minimizes cracks.

5. Chill and Finish

  • Remove cheesecake from the water bath and cool to room temperature. Then cover and chill in the fridge for at least 6 hours (overnight is best).
  • Before serving, whip heavy cream, sugar, and vanilla to soft peaks. Pipe or spread over the cheesecake. Garnish with additional key lime zest and lime slices for extra flair.

Expert Tips for Perfect Key Lime Cheesecake

  • Always use full-fat, room-temperature cream cheese and sour cream for the creamiest filling.
  • Both bottled and freshly squeezed key lime juice work well. If fresh key limes aren’t available, use Persian limes as a close substitute.
  • A water bath insulates the cake, allowing slow, even cooking and limiting cracks.
  • If cracks do occur, cover them artfully with whipped cream and garnishes.
  • Let the cheesecake chill fully for clean slices and the best texture.

Serving Suggestions & Variations

  • Tropical Toppings: Add toasted coconut, candied lime slices, or a drizzle of white chocolate for a unique spin.
  • Mini Cheesecakes: Divide the crust and filling among muffin tins lined with cupcake wrappers for individual servings.
  • No-Bake Shortcut: For a faster version, use a no-bake cheesecake base and chill until set—though the result will be softer.

Frequently Asked Questions

What is the best type of lime for key lime cheesecake?

Key limes are ideal for their distinct tart flavor, but regular Persian limes can be used as a substitute. If you can’t find fresh key limes, bottled key lime juice works just as well and is much easier to find in most grocery stores.

How do I know when my cheesecake is finished baking?

Your cheesecake is done baking when the edges are set, but the center is still slightly wobbly like gelatin. It will continue to firm up as it cools. Avoid overbaking, which can lead to a dry, cracked cake.

How long does key lime cheesecake keep in the refrigerator?

Stored tightly covered, this cheesecake will keep fresh in the refrigerator for up to five days. For longer storage, wrap slices and freeze for up to three months; thaw overnight in the fridge before serving.

Can I make this cheesecake ahead of time?

Absolutely! Key lime cheesecake should be made at least a day ahead to allow enough time for chilling and setting, which enhances both flavor and texture. It’s the perfect dessert for parties or holidays.

What should I do if my cheesecake cracks?

Even with the best techniques, small cracks may occur. Let your cheesecake chill completely before decorating, and use whipped cream, lime slices, or zest to cover imperfections. The flavor will be just as delicious.
