I bake my potatoes, let them cool then scoop them out. Or you can do it the cheater way and buy a can of sweet potatoes. I actually use canned sweet potatoes to make sweet potatoe pie and sweet potate bread.
I like plain baked sweet potatoes however this is the Sweet potato recipe that I would bring to family gatherings years agao. Evryone loved them
I whip my sweet potatoes with butter, brown sugar, cinncmon and 1 small can of chopped pineapple. Pile into a baking dish. Bake about 1/2 hour then remove from oven top with marshmellows and return to oven until golden brown.
