In the meantime, place all filling ingredients in a high-speed blender or food processor. Blend on high until you achieve a creamy texture, scraping down the sides as necessary. Pulse in Oreos at the end to keep some cookie chunks.
Let the filling ingredients cool in your fridge for about 10-15 minutes, then pour over the crust. Tap the pan lightly on your counter to remove air bubbles.
Prepare a water bath to bake your cheesecake by pouring hot tap water into a large casserole dish (deep enough to fit the height of your cheesecake pan). Fill up the casserole pan with water so that it reaches a little more than halfway up your cheesecake pan. Place the cheesecake pan into the casserole pan, then transfer everything to your oven. If using a springform pan, cover the bottom with aluminum foil to prevent water leakage. Bake at 325°F for 55 minutes, or until the middle is slightly "jiggly" but not liquidy when you shake it gently. The edges should be firm though.
Once the cheesecake is done, turn your oven off and open the door 1 inch. Leave the cheesecake in your oven for another hour to prevent cracking.
After 1 hour, remove cheesecake from the oven and cool at room temp for another 1 hour.
Put the cheesecake in your fridge uncovered (to prevent condensation forming on the top) for 4-6 hours, but preferably overnight.
