Sprinkle 1 cup of chocolate chips throughout the bottom of the baked Oreo crust.
Spread the cheesecake batter evenly throughout the pan.
Sprinkle the remaining 1 cup of chocolate chips evenly over the top of the cheesecake batter.
Bake for 60-75 minutes, or until there is a 3-4 inch jiggle in the center. Then turn off the oven and leave the cheesecake in the oven for another 1-2 hours or until the oven has cooled to room temperature.
Remove the cheesecake from the oven and let it cool completely to room temperature (another 1-2 hours), then place it in the refrigerator overnight to set.
Remove the spring form once the cheesecake has cooled to room temperature or after chilling overnight. Run a butter knife around the edges of the pan to loosen it first.
