Preheat oven to 325°F (160°C). Line a muffin pan with paper liners.
In a bowl, combine graham cracker crumbs, sugar, cinnamon, and melted butter. Press mixture firmly into the bottoms of the liners.
Bake crusts for 5 minutes, then remove and let cool.
In a large bowl, beat cream cheese and sugar until smooth. Mix in eggs one at a time. Add vanilla extract and blend until creamy.
In a separate bowl, stir together pumpkin puree, sugar, and pumpkin pie spice.
Spoon cheesecake batter over the crusts, filling each about 2/3 full. Drop spoonfuls of pumpkin mixture on top and use a toothpick to swirl.
Bake 25–28 minutes, until centers are set. Cool completely, then chill at least 2 hours before serving.
