Preheat oven to 350°F.
In a medium mixing bowl, combine cream cheese, granulated sugar, sour cream, and vanilla extract.
Beat at medium speed until smooth and creamy.
Spread mixture evenly into the bottom of a 10 inch pie plate.
Top with apple pie filling. *Note: if your apple pie filling has sliced apples, I would suggest chopping them for easier dipping.
In a separate small bowl, combine flour, melted butter, and brown sugar to create streusel topping.
Sprinkle topping over pie filling.
Bake at 350° for 25 minutes.
Drizzle with caramel topping as desired. Serve with vanilla wafers, crackers, pretzels, or your favorite dippers!
