Ingredients
To prepare a traditional Key Lime Pie, you will need the following ingredients.
For the crust:
- 1 ½ cups graham cracker crumbs (about 10 full crackers)
- ¼ cup granulated sugar
- 6 tablespoons unsalted butter, melted
For the filling:
- 1 can (14 ounces) sweetened condensed milk
- 4 large egg yolks
- ½ cup fresh Key lime juice (about 20–25 Key limes or 4–5 regular limes)
- 1 tablespoon Key lime zest (optional for extra flavor)
For the topping:
- 1 cup heavy whipping cream
- 2 tablespoons powdered sugar
- ½ teaspoon vanilla extract
Preparing the Graham Cracker Crust
Begin by preheating your oven to 350°F (175°C). While the oven heats, prepare the crust. In a medium-sized mixing bowl, combine the graham cracker crumbs and granulated sugar. Stir until the sugar is evenly distributed throughout the crumbs.
Next, pour in the melted butter and mix until the crumbs are fully moistened. The mixture should resemble wet sand in texture. Transfer the crumb mixture to a 9-inch pie dish. Press the mixture firmly into the bottom and up the sides of the dish using the bottom of a measuring cup or the back of a spoon. This will form a compact and even crust that holds together well during baking.
Place the pie dish in the preheated oven and bake for 8 to 10 minutes, or until the crust is lightly golden. Remove the crust from the oven and set it aside to cool slightly while you prepare the filling. This brief baking step helps the crust set and prevents it from becoming soggy once the filling is added.
Mixing the Key Lime Filling
While the crust cools, prepare the Key lime filling. In a large mixing bowl, whisk together the sweetened condensed milk and egg yolks until fully combined. The mixture should be smooth and pale in color. Add the freshly squeezed Key lime juice and lime zest, if using, and mix until everything is well incorporated. The acidity of the lime juice will begin to thicken the mixture slightly, which is a normal and desired reaction.
Once the filling reaches a smooth consistency, pour it into the partially cooled graham cracker crust. Use a spatula to spread the filling evenly, smoothing out the top for a clean finish. Return the pie to the oven and bake for 15 to 18 minutes. The edges should be set, and the center should jiggle slightly when gently shaken. Avoid overbaking, as this can cause the filling to crack.
After baking, remove the pie from the oven and allow it to cool at room temperature for 30 minutes. Then, place it in the refrigerator for at least 3 hours, or until fully chilled and firm. The chilling process allows the filling to set completely and enhances the flavor of the lime.
Preparing the Whipped Topping
While the pie is chilling, prepare the whipped topping. In a chilled mixing bowl, combine the heavy whipping cream, powdered sugar, and vanilla extract. Using a hand mixer or stand mixer fitted with the whisk attachment, beat the mixture on medium-high speed until soft peaks form. This typically takes about 3 to 4 minutes. Be careful not to overbeat, as the cream can quickly turn into butter if whipped too long.
Once the whipped cream is ready, cover and refrigerate it until the pie is fully chilled and ready to serve. You can spoon the whipped cream onto the pie or use a piping bag with a decorative tip to create a more elegant presentation.
Serving and Garnishing
When the pie has chilled thoroughly and the filling is set, it is ready to be garnished and served. Remove the pie from the refrigerator and top it with the prepared whipped cream. For an extra touch of flavor and color, sprinkle a small amount of lime zest over the whipped topping or place thin slices of lime around the edge of the pie.
To serve, slice the pie using a sharp knife dipped in warm water. Wipe the knife clean between slices for neat, clean cuts. Serve each slice chilled, garnished with a dollop of whipped cream and a twist of lime if desired. The pie pairs beautifully with iced tea, coffee, or a light dessert wine.
Tips for Success
Using fresh Key lime juice is highly recommended for authentic flavor. However, if Key limes are unavailable, bottled Key lime juice can be a suitable substitute. Be sure to choose a high-quality brand made from 100% juice, without added sweeteners or preservatives.
To make graham cracker crumbs quickly, place whole crackers in a food processor and pulse until finely ground. If you don’t have a food processor, place the crackers in a zip-top bag and use a rolling pin to crush them.
Allowing the pie to chill completely before slicing is crucial. This ensures clean cuts and a firm texture. If you’re short on time, you can place the pie in the freezer for about one hour to speed up the chilling process, but avoid freezing it for extended periods to preserve the creamy consistency.
For those seeking a lighter version of this dessert, consider using low-fat sweetened condensed milk and reduced-fat graham crackers. While the flavor may vary slightly, the pie will still have a pleasant texture and tart lime profile.
Variations and Customizations
This Key Lime Pie recipe is versatile and can be tailored to suit different tastes. For a tropical twist, add a few tablespoons of shredded coconut to the crust mixture. Coconut pairs well with lime and adds a subtle sweetness and texture.
If you prefer a meringue topping instead of whipped cream, reserve the egg whites from the yolks used in the filling. Whip them with sugar until stiff peaks form, spread over the baked filling, and bake for an additional 10 minutes until the meringue is golden.
Another variation includes adding a thin layer of white chocolate ganache between the crust and the filling. This adds richness and complexity, making the pie feel more indulgent.
For individual servings, divide the crust and filling among small tart pans or ramekins. This is an excellent option for dinner parties or special occasions, giving each guest their own personal dessert.
Storing Leftovers
To store leftover Key Lime Pie, cover it tightly with plastic wrap or aluminum foil and refrigerate. It will remain fresh for up to four days. For longer storage, you can freeze the pie (without the whipped topping) for up to one month. When ready to serve, allow it to thaw in the refrigerator overnight and add fresh whipped cream just before serving.
If freezing individual slices, wrap each one tightly in plastic wrap and place them in an airtight container. This method allows you to thaw only the number of servings you need while keeping the rest fresh.

Its simple preparation and impressive flavor make it an excellent choice for both novice bakers and experienced cooks.
