Preheat oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper, leaving an overhang on the sides.
For the crust: In a medium bowl, combine graham cracker crumbs and sugar. Pour in melted butter and stir until combined. Press mixture evenly into the bottom of the prepared pan.
Bake the crust for 8-10 minutes. Remove from oven and let cool slightly.
For the cheesecake layer: In a large bowl, beat cream cheese and sugar until smooth. Beat in the egg and vanilla extract until just combined.
Pour the cheesecake mixture over the prepared crust.
For the pumpkin pie layer: In a separate bowl, whisk together pumpkin puree, sugar, pumpkin pie spice, and salt.
Beat in the eggs one at a time, then stir in the evaporated milk until smooth.
Gently pour the pumpkin pie mixture over the cheesecake layer.
Bake for 30-35 minutes, or until the edges are set and the center is slightly jiggly.
Let cool completely in the pan on a wire rack. Chill for at least 2 hours before cutting into bars.
Notes
Serve chilled. These bars are perfect for holiday gatherings or as a delicious fall treat.
