Add eggs, vanilla extract, cinnamon, and nutmeg. Mix until well blended.

Bake for 45-50 minutes, or until a toothpick inserted in the center comes out clean.

In a large mixing bowl, combine mashed sweet potatoes, sugar, and melted butter. Mix until smooth.

Let the pie cool on a wire rack before serving.

Pour the sweet potato mixture into the unbaked pie crust.

Preheat the oven to 350°F (175°C).

Smooth out the top with a spatula.

Stir in evaporated milk until the mixture is smooth.
