Step1: Make Sweet Potato Pie Filling

Heat oven to 450 degrees. Put sweet potatoes on a baking sheet and brush each with vegetable oil. Place the sweet potatoes in the oven and bake for 45 minutes, until tender. Remove the sweet potatoes from the oven, allow to cool and then peel them to remove all of the skin. Put sweet potatoes in a large bowl and mash with a potato masher. Add butter and mix well. Add the sugar, milk, eggs, nutmeg, cinnamon, vanilla and mix well until the mixture is smooth.

Step 2: Bake And Serve Sweet Potato Pie

Pour sweet potato filling into an unbaked pie crust. Smooth the surface with a spatula. Bake at 350 degrees for 60 minutes or until light brown in color. Remove from the oven and allow to cool. Garnish with whipped topping and chopped pecans. Serve!
