Quoting SaucyPoppet:" Apple!! I'm not a fan of crunchy hard stuff (oreo) in soft stuff (cheesecake) though LOL"
The oreo probably doesn't stay crunchy inside the cheesecake. I made an oreo pie a few months back and the oreo kind of was.. hmm.. what is a good word... maybe soggy?
It was good, but soft, if that makes sense.
