Step 1: Prepare the Crust Preheat your oven to 350°F (175°C) and pulse the graham crackers into fine crumbs. Mix the crumbs with sugar, cinnamon, and melted butter, then press this firmly into a 9-inch springform pan. Bake for 8 minutes until it’s set and slightly golden, then let it cool completely for the best results.

Step 2: Make the Filling Reduce the oven temperature to 325°F (160°C) and beat the cream cheese with brown sugar until it’s light and fluffy. In another bowl, whisk together the pumpkin puree, eggs, sour cream, flour, pumpkin pie spice, salt, and vanilla extract. Add this mixture to the cream cheese on low speed, mixing just until combined to avoid overmixing.

Step 3: Bake and Cool Pour the filling onto the cooled crust and tap the pan gently to release air bubbles. Place a loaf pan half-filled with hot water on the rack below to create steam, then bake for 50-60 minutes until the edges set but the center still wobbles slightly. Turn off the oven, prop the door open, and let it cool inside for 30 minutes before removing and cooling fully at room temperature.

After that, wrap it tightly and refrigerate for at least 4 hours or overnight. This step ensures the flavors meld and the texture firms up nicely.

Step 4: Serve and Store Finally, remove from the pan, slice, and add your favorite toppings. The total prep time is about 7 hours 30 minutes, including chilling, so plan ahead for the best outcome.
