Preheat oven to 350 degrees and grease a 9x13 pan.
Combind topping and crust ingredients.
Press all but one cup of mixture into pan.
Bake 12 to 15 minutes until crust is set (it will not be brown) and cool.
With a mixer, beat cream cheese and sugar together in a bowl until smooth (note: if your cream cheese just came out of the refrigerator, you can microwave it on the defrost setting for a couple of minutes so that it's a little less difficult to beat with the mixer) Beat in eggs and vanilla.
Spread cream cheese mixture evenly over crust.
Combind apple mixture ingredients in a bowl.
Top cream cheese mixture evenly with apple mixture.
