Preheat the oven to 350 degrees F and grease a mini muffin pan (12 muffins).
Add 12 whole graham crackers, ¼ cup butter, melted, ¼ cup granulated sugar, ½ teaspoon salt, and ½ teaspoon cinnamon to the food processor and blend on high for 1 minute until the graham crackers are powdered and a thick crumble forms.
Transfer the crust to the muffin tins, packing ½ inch of crust in the bottom of each, set aside.
Using a stand mixer, combine ½ cup canned pumpkin, 8 ounces cream cheese, 1 large egg, 2 teaspoons vanilla extract, ¼ cup powdered sugar, and ¼ cup granulated sugar. Blend on high for 1 minute until a smooth, orange mixture forms.
Transfer the mixture to the muffin tins so that there is a 1-inch layer of filling in each.
Cook at 350 degrees F for 25-30 minutes until the cheesecake is firm. Allow the cheesecakes to cool for about 15 minutes in the pan and then remove to a cooling rack to cool completely. Chill for one hour before serving.
Serve with a dollow of whipped cream and a sprinkle of cinnamon.
Notes
To check if the cheesecake is fully cooked, gently shake the pan. If the filling is firm, then it is done cooking.
