Preheat your oven to 325°F (163°C). Line a 9x13 inch baking dish with parchment paper.
In a bowl, stir together graham cracker crumbs, 1/4 cup sugar, and melted butter. Press firmly into the bottom of the dish to form the crust.
In a separate large bowl, beat the cream cheese until smooth. Add 1 cup sugar and vanilla extract, and beat again until combined.
Add eggs one at a time, mixing gently after each until just incorporated. Don’t overbeat—think calm, not cardio.
Pour 2 cups of the cheesecake mixture over the crust and spread evenly.
In the remaining cheesecake batter, mix in pumpkin and spices. Spoon dollops of pumpkin mixture over the plain cheesecake layer.
Use a knife to gently swirl the two mixtures together—channel your inner abstract artist.
Bake for 38–42 minutes, or until the center is just set and the top looks matte.
Cool at room temperature, then chill in the fridge for at least 4 hours (overnight is better if you can wait).
Slice, serve, and watch them disappear faster than a PSL on the first day of fall.
