Preheat oven to 325 degrees F.

In a mixer bowl, blend cream cheese, sugar and sour cream until smooth. Scrape down sides of the bowl to incorporate all the sugar.

Add eggs, vanilla and flour; blend well. Remove springform pan from freezer.

Spoon ½ of batter into the pan. Sprinkle ¼ cup cinnamon chips and ¼ cup crushed cookies over batter. Dust with half of the cinnamon sugar. Top with remaining batter. Sprinkle remaining cinnamon chips and crushed cookies over batter. Top with the rest of the cinnamon sugar.

Position a large roaster pan in the center of your oven. Place springform pan in the center of the roaster pan. Carefully, fill roaster with boiling water until halfway up the side of the springform pan. Bake for 55 to 60 minutes or until the sides are set and the center of the cheesecake is still jiggly. Remove from water bath and let cool to room temperature.
