Copycat The Cheesecake Factory Key Lime Cheesecake Recipe – Bright, Creamy, and Refreshing

If you love the creamy richness of cheesecake but crave something bright and citrusy, this key lime version hits the sweet spot. It balances tangy lime flavor with a velvety smooth filling and a buttery graham cracker crust. The texture is dense yet silky, just like restaurant-style cheesecake.

It’s a special-occasion dessert that still feels relaxed and fun. Make it the day before, and you’ll have a chilled, sliceable beauty waiting in the fridge.

Why This Recipe Works

• Real key lime flavor: Using fresh key lime juice and zest gives that signature tartness without bitterness.
• Creamy, smooth texture: Room-temperature cream cheese and low-speed mixing prevent lumps and cracks.
• Sour cream for balance: A little sour cream adds tang and a custardy finish.
• Graham crust with a twist: A touch of sugar and salt balances the citrus and keeps the crust from tasting flat.
• Gentle bake in a water bath: This keeps the cheesecake moist and prevents curdling or collapsing.

Ingredients

Crust

• 1 1/2 cups graham cracker crumbs (about 12 full sheets)
• 2 tablespoons granulated sugar
• 1/4 teaspoon fine sea salt
• 6 tablespoons unsalted butter, melted

Filling

• 4 (8-ounce) blocks cream cheese, room temperature
• 1 cup granulated sugar
• 1/2 cup sour cream, room temperature
• 3 large eggs, room temperature
• 2 large egg yolks, room temperature
• 3/4 cup fresh key lime juice (or regular lime juice), strained
• 2 teaspoons key lime zest (from about 6–8 key limes or 2 regular limes)
• 1 teaspoon pure vanilla extract
• 1/4 teaspoon fine sea salt

Topping (Optional but Recommended)

• 1 cup cold heavy cream
• 2 tablespoons powdered sugar
• 1/2 teaspoon vanilla extract
• Extra lime zest or thin lime slices for garnish

Equipment

• 9-inch springform pan
• Heavy-duty aluminum foil
• Roasting pan for water bath
• Stand mixer or hand mixer

Step-by-Step Instructions

1. Prep the pan: Wrap the outside of a 9-inch springform pan tightly with two layers of heavy-duty foil to keep water out. Lightly grease the inside.
2. Heat the oven: Preheat to 325°F (163°C). Bring a kettle of water to a boil for the water bath.
3. Make the crust: Stir graham crumbs, sugar, and salt together. Add melted butter and mix until evenly moistened. Press firmly into the bottom and 1 inch up the sides of the pan.
4. Par-bake the crust: Bake for 10 minutes. Let cool slightly while you prepare the filling.
5. Beat the cream cheese: In a large bowl, beat cream cheese on medium-low until completely smooth, about 2 minutes. Scrape the bowl often.
6. Add sugar and salt: Mix in granulated sugar and salt on low until silky, 1–2 minutes.
7. Add sour cream and vanilla: Blend on low until combined. Avoid whipping too much air into the batter.
8. Add eggs and yolks: Add eggs and yolks one at a time, mixing on low just until combined after each addition. Scrape the bowl to catch any lumps.
9. Add lime juice and zest: Stir in key lime juice and zest on low until smooth. The batter will be pourable and creamy.
10. Fill the pan: Pour the filling into the crust. Tap the pan gently on the counter to release air bubbles.
11. Set up the water bath: Place the foil-wrapped pan in a large roasting pan.Pour hot water into the roasting pan to come halfway up the sides of the springform pan.
12. Bake: Bake at 325°F for 55–70 minutes. The edges should be set and slightly puffy; the center should wobble like Jell-O when nudged.
13. Turn off the oven: Crack the oven door and let the cheesecake rest inside for 45–60 minutes. This gentle cool prevents cracks.
14. Cool fully: Remove from the water bath. Discard foil. Cool on a rack to room temperature, about 1–2 hours.
15. Chill: Cover and refrigerate at least 6 hours, preferably overnight, until cold and fully set.
16. Make the whipped topping: Beat cold heavy cream, powdered sugar, and vanilla to medium peaks. Pipe or spread over the chilled cheesecake.
17. Garnish and serve: Add lime zest or thin slices. Run a thin knife around the edge before releasing the springform. Slice with a hot, clean knife for neat edges.

Storage Instructions

• Refrigerator: Cover tightly and refrigerate for up to 5 days. Keep whipped topping separate until serving if you want the cleanest slices.
• Freezer: Freeze whole or sliced without whipped cream. Wrap in plastic, then foil, and freeze for up to 2 months. Thaw overnight in the fridge.
• Make-ahead: The flavor improves after a full chill. Bake the day before and top just before serving.

Why This is Good for You

• Fresh citrus: Lime juice and zest bring vitamin C and a bright, uplifting flavor that makes smaller portions satisfying.
• Balanced sweetness: The tart lime lets you enjoy a rich dessert without it feeling heavy or overly sweet.
• Real ingredients: Simple dairy, eggs, and citrus—no artificial flavors needed for big taste.

What Not to Do

• Don’t rush the chill: Cutting too soon leads to messy slices and a soft center.Chilling sets the structure.
• Don’t skip room-temperature dairy: Cold cream cheese clumps and overmixing introduces air, which causes cracks.
• Don’t overbake: A firm center means it’s overdone. Stop when it still jiggles in the middle.
• Don’t skip the water bath: Dry heat can cause curdling and cracks. The bath keeps baking gentle and even.
• Don’t use bottled lime juice: It tastes dull and bitter.Fresh juice is worth it.

Alternatives

• Crust options: Swap graham crackers with vanilla wafers, Biscoff, or gingersnaps for a spiced twist.
• Dairy tweaks: Use full-fat Greek yogurt instead of sour cream for a slightly lighter tang.
• Lime blend: If you can’t find key limes, use half regular lime juice and half lemon juice for a bright, complex flavor.
• No water bath method: Bake at 300°F and place a pan of hot water on the lower rack. Not as foolproof, but helpful.
• Mini cheesecakes: Use a lined muffin tin with paper cups. Bake 18–22 minutes; chill as usual.

FAQ

Can I use regular limes instead of key limes?

Yes.

Regular limes work well. For a closer flavor match, use 2 parts regular lime juice to 1 part lemon juice, plus the zest of regular limes.

How do I prevent cracks?

Use room-temperature ingredients, mix on low, avoid overbaking, and cool gradually in the oven with the door ajar. A water bath is the biggest insurance policy.

What if I don’t have a springform pan?

Use a deep 9-inch cake pan lined with a parchment sling.

Chill thoroughly, then lift out carefully. The crust may be more delicate.

Can I make it gluten-free?

Yes. Use gluten-free graham crackers or a mix of almond flour and crushed gluten-free cookies.

Check that all other ingredients are certified gluten-free.

How do I get clean slices?

Use a sharp chef’s knife dipped in hot water. Wipe and re-dip between cuts. A chilled cheesecake and firm whipped topping also help.

Is the whipped cream necessary?

Not required, but recommended.

The light, creamy topping softens the tang and gives it that classic restaurant-style finish.

Can I reduce the sugar?

You can drop the filling sugar to 3/4 cup for a tangier cheesecake. Don’t go much lower or the texture and balance can suffer.

In Conclusion

This copycat key lime cheesecake brings the bright citrus punch and luxe texture you expect from a restaurant dessert, without the fuss. With fresh lime, a simple graham crust, and a careful bake, you get clean slices and a smooth, creamy interior.

Make it ahead, top with whipped cream, and serve chilled for a guaranteed crowd-pleaser.
