Sprinkle about one cup of chopped Halloween candy evenly throughout the bottom of the baked Oreo crust.
Spread half of the cheesecake batter evenly throughout the pan, covering the layer of Halloween candy.
Sprinkle about one cup of chopped Halloween candy evenly over the cheesecake batter.
Spread the remaining cheesecake batter over the Halloween candy. Tap the pan against the counter a few times to release any air bubbles and even out the 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. Once the cheesecake has reached room temperature, cool it in the fridge for at least 4 hours (preferably overnight). Once the cheesecake has chilled you can run a butter knife around the bottom and sides of the pan to release it.
