In a stand mixer with a paddle attachment, beat the neufchatel cheese until smooth.
Add the truvia and molasses, and beat again.
Beat in cinnamon, oat fiber, vanilla, and sour cream.
Add eggs one at a time, beating after each addition until just combined.
Stir or beat in the apples.
Pour the cheesecake filling into your freshly baked crust, and carefully place springform pan (still with foil on the outside) into a large oven safe dish.
Fill the outer dish with water so that it comes up about an inch high on the springform pan.
Carefully place the two nested dishes (one with water and one with cheesecake) into the hot oven and bake for 1 hour and 10 minutes or until the top of the cheesecake is lightly browned and feels firm when lightly pressed.
Remove from oven and cool, then refrigerate for 8 hours or overnight.
