Step 1: Prepare the Crust

1. Preheat your oven to 350°F (175°C).
2. In a medium bowl, combine graham cracker crumbs, sugar, and melted butter. Mix until the crumbs are evenly coated.
3. Press the mixture firmly into the bottom and sides of a 9-inch pie pan to form a crust. Use the back of a spoon for an even layer.
4. Bake the crust for 8–10 minutes until slightly golden. Remove from the oven and let it cool.

Step 2: Make the Custard Filling

1. In a large mixing bowl, whisk together eggs, sugar, and cornstarch until smooth.
2. Gradually add the warm milk while whisking constantly to prevent curdling.
3. Stir in the vanilla extract for a fragrant and flavorful custard.

Step 3: Assemble the Pie

1. Pour the custard filling into the prepared crust.
2. Carefully transfer the pie to the oven and bake for 30–35 minutes, or until the center is set but still slightly jiggly.

Step 4: Cool and Chill

1. Allow the pie to cool at room temperature for 1 hour, then refrigerate for at least 2 hours before serving.
