optional: graham cracker crumbs, caramel sauce, pecans
Chop the tops of the apples off and scoop out the insides. Discard the core and seeds.
In a medium bowl cream together cream cheese and sugar until smooth. Mix in vanilla, egg, and cinnamon until smooth. Fill each of the apples ⅔ full with the cheesecake mixture.
Place filled apples on a baking sheet (make sure they aren't touching) and bake at 350 for 20-25 minutes until cheesecake filling is set. Transfer to a plate and place in the fridge until completely cooled.
Serve apples at room temperature or chilled. If desired, top with caramel sauce, graham cracker crumbs, and pecans.
