Step 1: Preheat Your Oven
Preheat the oven to 350°F (175°C). Place the rack in the center of the oven.
Step 2: Prepare the Crust
In a mixing bowl, combine graham cracker crumbs and sugar. Stir in the melted butter until the crumbs are evenly coated. Press the mixture firmly into the bottom and up the sides of a 9-inch pie pan. Use the back of a measuring cup to smooth it out. Bake the crust for 8–10 minutes. Remove from oven and let it cool slightly.
Step 3: Make the Filling
In another bowl, whisk the egg yolks until slightly thickened. Add the sweetened condensed milk and lime zest, whisking until smooth. Gradually add the lime juice while stirring until fully incorporated. The filling should be slightly thick and creamy.
Step 4: Bake the Pie
Pour the filling into the baked crust. Bake for 15 minutes or until the filling is set but still slightly jiggly in the center. It will continue to firm up as it cools.
Step 5: Chill the Pie
Let the pie cool at room temperature for 30 minutes, then refrigerate for at least 3 hours or preferably overnight for the best flavor and texture.
Step 6: Add the Topping
Just before serving, whip the heavy cream, powdered sugar, and vanilla extract until stiff peaks form. Pipe or spread the whipped cream over the chilled pie.
Serving Suggestions
Key Lime Pie is best served chilled. Here are a few ways to make it shine:
- Garnish with thin lime slices or lime zest curls - Serve with a sprig of mint for color contrast - Pair with a cup of black tea or iced coffee - Add toasted coconut flakes for a tropical twistMake-Ahead & Storage Tips
