They put out a oreo cheesecake box mix at Christmas. It is a pudding type mix and the crust is an oreo crust. You mix the crust with butter and put in a pan. It could have come with it's own "pan". Then you mix the cheesecake part like you would instant pudding. Pour the cheesecake in the crust and refrigerate for a couple of hours.

we've had it and it is really good! I don't know if this is what you are looking for but your description made me think of this one. I don't know if it is Jello brand or not. That is the brand of cheesecake mix I have in the cupboard now. You would find it in the pudding area I would think. I have bought it at Walmart in times past.

Thank you all for help in finding an this elusive oreo recipe.. I'll have to make these to see if one of them might be it..

I haven't read in detail all the recipes that were posted but there is also (if it wasn't mentioned yet) one calle "Dirt or Dirty Pudding".. It has a "crust" (I make it in a 9x13 pan) made of crushed oreos & butter and then a layer of pudding made of cream cheese, french vanilla boxed pudding and cool whip I believe.. then you top it with some more of the crushed oreo stuff. Let me know if you want the recipe.. email me at [email protected] and put Oreo in the subject line so I will know.
