Preheat oven to 350-f degrees. Place cupcake liners in a regular sized muffin pan.
Beat the cream cheese and sugar until light and fluffy. Add the egg and beat. Add the sour cream, vanilla, pumpkin, and cinnamon and beat until creamy.
Place half of an Oreo in the bottom of the cupcake liners and fill the liner 3/4 full with the cheesecake batter. Place another half of an Oreo into the top of the batter. Bake for 22 minutes. Cool in pan for 15-20 minutes before removing and placing on a wire rack to finish cooling. Keep refrigerated.
