In a food processor or blender, combine graham crackers, melted butter, and granulated sugar. Firmly press the mixture into a lined 13×9 baking dish.
In a stand mixer, beat cream cheese and granulated sugar until smooth. Add eggs one at a time, followed by vanilla extract. Pour the creamy mixture over the graham cracker crust.
Peel and chop Granny Smith apples using a star chopper. Toss apples with granulated sugar, cinnamon, and pumpkin pie spice. Sprinkle the spiced apples evenly over the cheesecake layer.
In a bowl, combine melted butter, flour, brown sugar, oats, and cinnamon. Sprinkle the crumble over the spiced apple layer.
Bake the masterpiece at 350°F for 45-50 minutes, or until the top is golden and the edges are set. Once done, let it cool, then transfer to the fridge for 2 hours to set.
Once chilled, slice into 16 bars. Enjoy these easy apple crumble cheesecake bars as a satisfying ending to your meal.
