Florida Key Lime Pie
Key Lime Pie is famous for its simple combination of a crisp graham cracker crust, creamy citrus filling and cool whipped topping. Each bite balances sweetness from condensed milk with the bright acidity of lime juice.
The filling needs surprisingly few ingredients. Egg yolks provide richness and structure, while sweetened condensed milk creates the signature creamy consistency. Fresh lime zest adds another layer of citrus aroma that makes the finished pie especially refreshing.
Finished with homemade whipped cream and a little extra lime zest, this pie makes an impressive dessert without requiring complicated decorating.

Ingredients
For the Graham Cracker Crust
- 1½ cups (150 g) graham cracker crumbs
- 6 tbsp (85 g) unsalted butter, melted
- 2 tbsp granulated sugar
- Pinch of salt
For the Key Lime Filling
- 1 can (14 oz / 395 g) sweetened condensed milk
- 4 large egg yolks
- ½ cup (120 ml) Key lime juice or fresh lime juice
- 1 tbsp finely grated lime zest
- Pinch of salt
For the Whipped Cream
- 1 cup (240 ml) cold heavy whipping cream
- 2 tbsp powdered sugar
- 1 tsp vanilla extract
Optional Garnish
- Fresh lime slices
- Additional lime zest
- Graham cracker crumbs
Instructions
1. Prepare the Oven
Preheat the oven to 175°C (350°F).
Lightly grease a 9-inch (23 cm) pie dish.
2. Make the Graham Cracker Crust
Place the graham cracker crumbs in a mixing bowl.
Add the granulated sugar and salt, then pour in the melted butter.
Stir until all the crumbs are evenly moistened. The mixture should resemble damp sand and hold together when pressed.
3. Form the Crust
Transfer the mixture to the pie dish.
Press the crumbs firmly across the bottom and up the sides. The bottom of a measuring cup works well for creating an even, compact crust.
4. Bake the Crust
Bake for 8–10 minutes, until lightly golden and fragrant.
Remove from the oven and let it cool slightly while preparing the filling.
Keep the oven at 175°C (350°F).
5. Prepare the Lime Filling
Place the egg yolks in a large bowl.
Whisk for about 1–2 minutes, until slightly thickened.
Add the sweetened condensed milk and whisk until completely smooth.
Pour in the lime juice gradually while whisking.
Add the lime zest and a small pinch of salt.
Continue whisking until the filling is smooth and slightly thickened.
6. Fill the Pie
Pour the lime mixture into the warm graham cracker crust.
Spread it evenly with a spatula if necessary.
7. Bake
Return the pie to the oven.
Bake for approximately 12–15 minutes.
The filling should look set around the edges while the center still has a slight wobble when the dish is gently moved.
Avoid overbaking because the filling will continue setting as it cools.
8. Cool
Remove the pie from the oven and allow it to cool completely at room temperature.
Once cooled, cover and refrigerate for at least 4 hours.
For an especially firm and refreshing pie, chill it overnight.
9. Prepare the Whipped Cream
Shortly before serving, pour the cold heavy whipping cream into a mixing bowl.
Add the powdered sugar and vanilla.
Whip until medium-to-stiff peaks form.
Avoid overwhipping.
10. Decorate and Serve
Spread or pipe the whipped cream over the chilled pie.
Decorate with fresh lime slices and finely grated lime zest.
Slice and serve cold.
Key Limes vs. Regular Limes
Key limes are smaller than the Persian limes commonly sold in supermarkets. They have a distinctive aromatic, tart flavor traditionally associated with Key Lime Pie.
If fresh Key limes aren’t available, regular fresh lime juice can still produce an excellent pie.
Freshly squeezed juice generally provides a brighter flavor than standard bottled lime juice.
Tips for the Best Key Lime Pie
Allow the crust to cool slightly before adding the filling.
Use finely grated zest and avoid the bitter white pith underneath the lime skin.
Don’t overbake the filling. A slight wobble in the center is normal when the pie leaves the oven.
Give the pie the full chilling time. Cutting it too soon can produce soft slices that don’t hold their shape.
Keep the whipping cream very cold for better volume.
Variations
For a coconut Key Lime Pie, add toasted coconut to the graham cracker crust or sprinkle it over the whipped topping.
For mini Key Lime pies, divide the crust and filling among small tart pans or muffin cups.
For extra citrus flavor, add additional fresh lime zest to the filling.
You can also replace part of the graham cracker crumbs with finely crushed digestive biscuits if graham crackers aren’t readily available.
Serving Ideas
Key Lime Pie is best served thoroughly chilled.
A little whipped cream helps balance the tart citrus filling, while fresh lime zest gives each slice additional fragrance.
For a simple presentation, serve each slice with whipped cream and a thin lime wheel.
Make-Ahead Tips
This is an excellent dessert to prepare the day before serving.
Make and bake the entire pie, allow it to cool, then refrigerate overnight. Prepare the whipped cream and decorate the pie closer to serving time for the freshest appearance.
Storage
Cover the pie and refrigerate for up to 3–4 days.
Because the filling and topping contain dairy and eggs, keep the pie refrigerated rather than leaving it at room temperature for long periods.
Individual slices can also be frozen without the whipped cream topping. Wrap them carefully and freeze for up to 1 month. Thaw overnight in the refrigerator before serving.
