Prep the pan: Line a standard 12-cup muffin pan with paper liners. Heat the oven to 325°F (163°C).
This lower temperature helps prevent cracking.
Make the crust: In a bowl, mix graham crumbs, sugar, cinnamon, salt, and melted butter until the mixture looks like damp sand and holds together when pressed.
Press and pre-bake: Divide the crust mixture evenly among the liners (about 1 to 1 1/2 tablespoons each). Firmly press down with the bottom of a small glass or spoon. Bake for 5–6 minutes, then let cool slightly while you make the filling.
Beat the cream cheese: In a large bowl, beat cream cheese on medium speed until completely smooth and creamy, about 2 minutes.
Scrape down the bowl to avoid lumps.
Add sugar and pumpkin: Beat in the granulated sugar until combined, then mix in the pumpkin puree. Keep the mixer on low to medium-low to avoid too much air.
Mix in eggs and flavorings: Add eggs one at a time, mixing just until combined after each. Add sour cream, vanilla, pumpkin pie spice, cinnamon, and salt.
Mix until smooth and uniform. Do not overbeat.
Fill the cups: Spoon the batter over the crusts, filling each liner almost to the top. Gently tap the pan to release any air bubbles.
Bake: Bake at 325°F for 16–20 minutes.
The centers should be slightly jiggly but not liquid. The edges will look set. Avoid overbaking.
Cool gradually: Turn off the oven, crack the door, and let the cheesecakes sit for 5 minutes.
Move the pan to a cooling rack and cool to room temperature.
Chill: Refrigerate for at least 3 hours, preferably overnight, to set the texture and deepen the flavor.
Top and serve: Add whipped cream, a drizzle of caramel or maple syrup, and a sprinkle of cinnamon or nuts right before serving.
