1) Preheat oven to 350 degrees.
2) Combine all ingredients in a medium bowl and whisk well to combine. This mixture will not be perfectly smooth because of the applesauce.
3) Pour filling into prepared crust and bake 25-30 minutes, until the center is set and does not jiggle when lightly shaken. (I just spray an 8x8x2" glass baking container rather than a crust).
4) Remove bars from oven and allow to cool completely. Transfer to fridge and let chill to set 1 hour (Or overnight) before serving.
5) I serve with a dollup of whipped cream.
