Preheat oven to 325°F (163°C) and line a 12-cup muffin pan with paper liners.
Mix graham cracker crumbs, sugar, and melted butter until evenly combined.
Press about 1 tablespoon of the crumb mixture firmly into the bottom of each liner.
Beat the cream cheese until smooth and creamy.
Mix in pumpkin puree, sugar, egg, vanilla, pumpkin pie spice, cinnamon, flour, and salt until fully combined.
Divide the filling evenly over the prepared crusts.
Bake for 18–20 minutes until the centers are just set.
Cool completely at room temperature.
Refrigerate for at least 2 hours before serving.
Top each cheesecake with whipped cream, caramel drizzle, and a light sprinkle of cinnamon before serving.
