Graham Cracker Crust

• Crush the graham crackers in a food processor or by placing in a large ziploc bag and crushing with a rolling pin. Make sure the crumbs are very fine. Transfer to a large bowl.
  15 graham crackers
• Stir in the sugar and then drizzle in the melted butter. Stir until thoroughly combined.
  3 tablespoons granulated sugar, 8 tablespoons salted butter
• Press the crumbs into the bottom of the prepared pan forming an even layer. Cover with plastic wrap and place the crust in the freezer while preparing the remaining layers.

Apple Layer

• In a medium bowl, combine the chopped apples and fresh lemon juice and toss together. Add the granulated sugar, brown sugar, pumpkin pie spice and salt. Stir together until all the ingredients are evenly incorporated. Set aside.
  3 Granny Smith apples, ¼ cup granulated sugar, 3 tablespoons brown sugar, 1 teaspoon apple pie spice, ¼ teaspoon salt, 1 tablespoon lemon juice

Cheesecake Layer

• Place the softened cream cheese and sugar in a large mixing bowl and then, using a hand or stand mixer, beat on medium speed until well combined, about 2 minutes. The mixture should be smooth and creamy.
  24 ounces cream cheese, 1 ¼ cup powdered sugar
• Add the sour cream and vanilla extract and mix on low speed just until combined.
  ⅓ cup sour cream, 1 ½ teaspoons vanilla extract
• Add the eggs and mix on low speed just until incorporated, do not overmix. Set aside.

Assembly

• Spoon the apple mixture over the cheesecake layer using a slotted spoon.
• Spoon the crumb topping evenly over the apple layer.
• Bake for 35 to 45 minutes or until the sides are set and the middle has a very slight jiggle.
