Make the Pumpkin Pie Batter.
Fill the cups or ramekins ⅔’rds full with plain cheesecake batter.

Bake for 50 minutes at 300 degrees on a cookie sheet in the center of the oven. Turn the oven off after 50 minutes and leave the cheesecakes in the oven for 15 minutes before removing to a wire rack to finish cooling.
After they have cooled, cover and move to the refrigerator to chill. Chill for 3-4 hours. Add chopped pecans or whipping cream piped or dollops.
