Blend all of the above EXCEPT PUMPKIN for about 2 minutes on HIGH until creamy smooth and warm. Lastly, add pumpkin and mix again, just until blended evenly.
Pour into a pie pan or baking dish.
Bake @ 425 degrees for 15 minutes; reduce temperature to 350 degrees and continue baking for 45-50 minutes more. Cool and serve with whipped topping. (May also be served slightly warm – will have a softer texture.)
May make crumb topping of toasted pecans and graham crackers.
