Heat a large cooking pot and pour-in water. Bring to a boil.

Put-in sweet potatoes then simmer for 45 minutes in medium heat.

Turn-off heat and remove the sweet potatoes. Let cool.

Run cold water on the potatoes while gently peeling the skins off. This can easily be done using your fingers.

Mash the sweet potatoes using a fork, a masher, or a pastry mixer.

Combine the mashed sweet potato and butter then mix well. You may use an electric mixer to make things easier.

Put-in milk, eggs, nutmeg, cinnamon, vanilla, and sugar then mix until the texture becomes smooth.

Preheat oven to 350 degrees Fahrenheit.

Arrange the mixture on the pie crust.

Bake for 45 to 55 minutes or until it passes the toothpick test.

Remove from the oven and let cool.

Serve. Share and enjoy!
