Boil the Sweet Potato:
Place the whole sweet potato in a pot and cover with water.
Bring to a boil and cook until tender when pierced with a fork, about 40 to 50 minutes.
Prepare the Sweet Potato:
Preheat the oven to 350°F (175°C).
Remove the sweet potato from the pot and run it under cold water.
Peel off and discard the skin.
Break the sweet potato flesh apart and place it in a bowl.
Make the Filling:
Add the softened butter to the sweet potato flesh.
Mix with an electric mixer until well combined.
Add the sugar, condensed milk, eggs, nutmeg, cinnamon, and vanilla extract.
Beat on medium speed until the mixture is smooth.
Assemble and Bake:
Pour the filling into the unbaked pie crust.
Bake in the preheated oven for 55 to 60 minutes, or until a knife inserted in the center comes out clean.
Remove from the oven and let cool before serving. Enjoy!!
