Sweet Potato Pie Filling

Scrub sweet potato, prick the skin, and bake at 350 degrees for 45 minutes, or until potato is soft throughout. Remove from oven, place on a rack until cooled. Remove flesh and discard the skin; mash flesh with a fork. In a large bowl, using an electric mixer on medium speed, beat potato pulp with sugars and remaining ingredients until batter is smooth, about 2 minutes.
