Ingredients
Graham Cracker Crust
- 1.5 cups graham cracker crumbs (about 10 whole crackers)
- 6 tablespoons unsalted butter, melted
- 3 tablespoons granulated sugar
- ⅛ teaspoon salt
Key Lime Filling
- 4 egg yolks
- ¾ cup Key lime juice (fresh or bottled)
- 1 tablespoon Key lime zest
- 28 ounces sweetened condensed milk
Whipped Cream Topping
- 1 cup heavy whipping cream
- 2 tablespoons powdered sugar
- 1 teaspoon vanilla extract
- lime slices (optional, for garnish)
- lime zest (optional, for garnish)
Instructions
- Prepare Graham Cracker Crust: Preheat your oven to 325°F (165°C) and lightly spray a 9-inch pie pan with cooking spray. In a food processor, pulse whole graham crackers until they resemble sand. Add melted butter, granulated sugar, and salt; pulse until well combined. Press the mixture firmly and evenly into the bottom and sides of the pie pan. Bake for 8-10 minutes, then remove and allow to cool completely while leaving the oven on.
- Make Key Lime Filling: In a medium bowl, whisk together egg yolks, Key lime juice, and Key lime zest until the mixture lightens slightly in color. Gradually whisk in sweetened condensed milk until smooth. Pour this filling into the cooled graham cracker crust. Bake in the preheated oven for 12-15 minutes until the center is just barely set with a slight jiggle.
- Cool and Chill the Pie: Let the baked pie cool at room temperature for 1 hour. Then transfer it to the refrigerator or freezer if you prefer a frozen pie. Chill for at least 4 hours before serving to allow the filling to fully set.
- Prepare Whipped Cream Topping: Using a stand mixer fitted with a whisk attachment or a handheld mixer with a large bowl, whip the heavy cream, powdered sugar, and vanilla extract on medium-high speed until medium soft peaks form.
- Serve: Just before serving, spread or pipe the whipped cream over the chilled pie. Garnish with lime slices or additional lime zest for an extra burst of citrus aroma and presentation.
Notes
- Use fresh Key lime juice whenever possible for the best authentic flavor; bottled juice is a convenient alternative.
- If you prefer a firmer texture, chill the pie overnight.
- To make a frozen Key lime pie, chill the pie in the freezer after cooling at room temperature.
- Ensure not to overbake the filling; it should still have a slight jiggle in the center when done.
- For a gluten-free option, substitute graham cracker crumbs with gluten-free alternatives.
- Whipped cream can be sweetened more or less to taste or substituted with coconut cream for a dairy-free version.
