The lactic acid bacteria in cream cheese offsets the sweetness of the potatoes with a nuanced level of tanginess, enhanced by spices like cinnamon, nutmeg, and ground cloves.
Use a hand mixer to whip an 8-ounce block of room-temperature cream cheese, add the cooked sweet potato, sugars, eggs, and spices, pour into the crust, and bake as usual.
If you want your sweet potato pie to be more similar to cheesecake, substitute the sugars with 8 ounces of cream cheese and a 14-ounce can of sweetened condensed milk.
For a visual appeal, make two tasty yet distinct layers when sliced with cream cheese, sugar, egg, and vanilla on the bottom and the classically made sweet potato layer on top.
