Ingredients:
- 1.5 cups (170g) graham cracker crumbs
- 6 tbsp (85g) unsalted butter, melted
- 1/3 cup (65g) granulated sugar
- 1 pinch fine sea salt
- 8 oz (225g) full-fat cream cheese, softened
- 14 oz (396g) sweetened condensed milk
- 0.5 cup (120ml) key lime juice
- 1 tbsp key lime zest
- 8 oz (225g) whipped topping (like Cool Whip)
Instructions:
- In a medium bowl, combine the graham cracker crumbs, granulated sugar, salt, and melted butter until the texture resembles wet sand.
- Press the mixture firmly into the bottom and up the sides of a 9-inch deep-dish pie plate. Use a flat-bottomed cup to pack it tightly. Place the crust in the freezer for 10 minutes to set.
- In a large mixing bowl, beat the softened cream cheese using an electric mixer until completely smooth and creamy.
- Gradually add the sweetened condensed milk, beating continuously until well combined.
- Stir in the key lime juice and lime zest. The mixture will begin to thicken naturally due to the reaction between the lime acid and the dairy proteins.
- Using a rubber spatula, gently fold in the whipped topping until the filling is uniform and light.
- Pour the filling into the chilled crust and smooth the top. Refrigerate for at least 6 hours (or overnight) to allow the pie to set to a sliceable consistency.
