Why You’ll Love This Recipe
This pie delivers that classic sweet-tart balance that makes key lime desserts so popular. The filling is velvety and full of fresh citrus flavor, while the graham cracker crust adds just the right amount of crunch and buttery richness. It is also a great make-ahead dessert because it needs time to chill, which means less last-minute work before serving. Another reason to love it is how simple the ingredient list is. Even though the finished pie looks impressive, the process is easy and approachable for home bakers.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the crust:
1 1/2 cups graham cracker crumbs
1/4 cup granulated sugar
6 tablespoons unsalted butter, melted
1 pinch salt
For the filling:
4 large egg yolks
2 cans sweetened condensed milk, 14 ounces each
3/4 cup key lime juice
2 tablespoons lime zest
1 teaspoon vanilla extract
1 drop green food coloring, optional
For the topping:
1 cup heavy whipping cream, cold
3 tablespoons powdered sugar
1/2 teaspoon vanilla extract
Thin lime slices or a little extra lime zest, for garnish
Directions
Preheat your oven to 350°F. In a medium bowl, stir together the graham cracker crumbs, granulated sugar, salt, and melted butter until the texture looks like wet sand. Press the mixture firmly into the bottom and slightly up the sides of a 9-inch pie dish or springform pan. Bake the crust for 8 to 10 minutes, then remove it from the oven and let it cool completely.
To make the filling, place the egg yolks in a large bowl and whisk until smooth. Add the sweetened condensed milk and whisk until fully blended. Slowly pour in the key lime juice, then add the lime zest and vanilla extract. If you want the pie to have a more classic bakery-style light green tint, stir in a tiny drop of green food coloring. Mix just until smooth.
Pour the filling into the cooled crust and spread it evenly. Return the pie to the oven and bake for 15 to 18 minutes. The center should look set but still have a slight jiggle. Remove it from the oven and let it cool at room temperature.
Once cooled, transfer the pie to the refrigerator and chill for at least 6 hours, or overnight for the best texture. Before serving, whip the cold heavy cream with powdered sugar and vanilla extract until stiff peaks form. Pipe or spoon the whipped cream over the chilled pie, then garnish with lime slices or a sprinkle of lime zest. Slice and serve cold.
Servings and timing
This recipe makes 1 nine-inch pie, which serves 10 to 12 slices.
Prep time: 25 minutes
Bake time: 25 minutes
Chill time: 6 hours or more
Total time: about 6 hours 50 minutes, including chilling
Variations
For a stronger citrus flavor, add a little extra lime zest to the filling. You can also use a mix of key lime juice and regular fresh lime juice if key limes are hard to find. For a slightly different crust, try using crushed vanilla wafers instead of graham crackers. If you want a cleaner, more classic finish, skip the food coloring and let the filling keep its natural pale yellow color. You can also serve each slice with extra whipped cream for a more restaurant-style presentation.
Storage/Reheating
Store the pie covered in the refrigerator for up to 4 days. For the freshest presentation, add the whipped topping shortly before serving, although a fully assembled pie also keeps well when chilled. If you want to make it ahead, prepare the pie a day or two in advance and keep it refrigerated until needed.
This dessert is not meant to be reheated. It should always be served cold for the best flavor and texture. You can also freeze the pie without the topping for up to 1 month. Thaw it overnight in the refrigerator before decorating and serving.
FAQs
Can I use regular lime juice instead of key lime juice?
Yes, regular lime juice works well, though key lime juice gives the pie its more distinctive tart flavor.
Why does the filling set without a lot of baking?
The combination of egg yolks, condensed milk, and citrus juice helps the filling thicken and set as it bakes and chills.
Do I need fresh limes for this recipe?
Fresh limes are great for zest, but bottled key lime juice is convenient and gives a reliable flavor.
Can I make this pie ahead of time?
Yes, it is actually better when made ahead because the long chilling time helps it firm up nicely.
How do I know when the pie is done baking?
The edges should look set and the center should still jiggle slightly when you gently move the pan.
Can I use a store-bought crust?
Yes, a ready-made graham cracker crust can save time, though a homemade crust tastes richer and fresher.
Why is my pie too soft?
It may need more chilling time, or it may have been slightly underbaked.
Can I freeze leftover slices?
Yes, freeze slices without the whipped topping and thaw them in the refrigerator before serving.
What is the best way to get neat slices?
Use a sharp knife dipped in hot water, then wipe it clean between each cut.
Is the green food coloring necessary?
No, it is completely optional and only changes the appearance, not the flavor.

Copycat Cheesecake Factory Key Lime Pie is a refreshing dessert that combines creamy texture, vibrant citrus flavor, and a crisp buttery crust in every bite.
