Reserve 1 cup of the mixture and put aside.
Spray a 9 x 13″ baking dish with non-stick spray. Press crumble mixture in to baking dish to create a crust. Bake for 10 minutes.
While the crust bakes combine your cream cheese, sugar, remaining egg, and vanilla in a small bowl. Beat with an electric mixer until smooth and creamy.
Remove baking dish from oven and pour the 2 cans of cherry pie filling over crust and create an even layer.
Next pour your cream cheese mixture over the cherry filling. Smooth out with the back of a spoon so the cream cheese layer covers the whole dish.
Grab your remaining crumble mixture that you reserved and sprinkle evenly over the top of the cream cheese mixture.
Bake for 30 minutes. Remove from oven and allow to cool for at least 30 minutes.
Serve with vanilla ice cream or a whipped topping of choice. This dish can be made with any canned pie filling. (Serves 8-10)
