Ingredients
For the Graham Cracker Crust
1 ½ cups graham cracker crumbs
¼ cup granulated sugar
6 tablespoons unsalted butter, melted
For the Key Lime Filling
2 cans (14 oz each) sweetened condensed milk
4 large egg yolks
¾ cup Key lime juice
1 tablespoon Key lime zest
For the Whipped Cream
1 cup heavy whipping cream, cold
3 tablespoons powdered sugar
½ teaspoon vanilla extract
Fresh lime slices or zest, optional for garnish
Instructions
Make the Crust
Preheat your oven to 350°F (175°C).
Combine the graham cracker crumbs and granulated sugar in a medium bowl.
Pour in the melted butter and stir until the crumbs are evenly coated.
Press the mixture firmly into the bottom and up the sides of a 9-inch pie dish.
Bake for 8–10 minutes, then remove from the oven and let it cool slightly.
Make the Key Lime Filling
Whisk the egg yolks in a large bowl until smooth.
Add the sweetened condensed milk and whisk until fully combined.
Stir in the Key lime juice and lime zest.
Mix just until the filling is smooth and evenly combined.
Bake the Pie
Pour the filling into the prepared graham cracker crust.
Smooth the top with a spatula.
Bake at 350°F for 15–18 minutes, until the edges are set and the center has a slight jiggle.
Remove from the oven and allow the pie to cool completely.
Refrigerate for at least 4 hours, or preferably overnight.
Make the Whipped Cream
Add the cold heavy whipping cream, powdered sugar, and vanilla to a mixing bowl.
Beat until medium-to-stiff peaks form.
Spread or pipe the whipped cream over the chilled pie.
Garnish with fresh lime zest or thin lime slices if desired.
Tips for the Best Key Lime Pie
Zest your limes before squeezing them.
Measure the lime juice instead of estimating.
Don't overmix the filling.
Pack the graham cracker crust firmly so it holds together when sliced.
Give the pie at least 4 hours to chill before serving.
For cleaner slices, wipe your knife between each cut.
Keep leftovers covered in the refrigerator.
Storage
Store your Key Lime Pie covered in the refrigerator for up to 3–4 days. Keep it chilled until you're ready to serve.
Serving Suggestion
Serve each cold slice with extra whipped cream, fresh lime zest, or a few berries for a refreshing finishing touch.
