Ingredients

For the Crust:

• 1 ½ cups graham cracker crumbs
• ⅓ cup granulated sugar
• 6 tablespoons melted unsalted butter

For the Filling:

• 4 large egg yolks
• 14 oz sweetened condensed milk
• ½ cup freshly squeezed key lime juice
• 1 tablespoon grated key lime zest

For the Topping (Optional):

• 1 cup whipped cream
• Thin lime slices for garnish

Instructions

Step 1: Prepare the Crust

Preheat oven to 350°F (175°C). In a bowl, mix graham cracker crumbs, sugar, and melted butter until well combined. Press the mixture firmly into a 9-inch pie dish, covering the bottom and sides evenly. Bake for 10 minutes, then let it cool while you prepare the filling.

Step 2: Make the Filling

In a mixing bowl, whisk the egg yolks until smooth. Gradually add the sweetened condensed milk, key lime juice, and zest, whisking until fully incorporated. Pour the filling into the pre-baked crust.

Step 3: Bake and Chill

Bake the pie for 15-17 minutes, until the filling is set but still slightly jiggly in the center. Let it cool to room temperature, then refrigerate for at least 4 hours (preferably overnight) to firm up.

Step 4: Garnish and Serve

Before serving, top with whipped cream and lime slices if desired. Slice and enjoy chilled!

Tips

• For the best flavor, use fresh key limes.
• The pie can be stored in the refrigerator for up to 3 days.
