THIS IS THE BEST CHOCOLATE CHEESECAKE YOU CAN EVER MAKE! Now that I have your attention. I have made this MANY, MANY times and gotten nothing but RAVES about it. I have even sold it to friends that had tasted it at work! (I fixed one for overtime at my work one Saturday from 7:00 a.m. to 12:00 p.m. It was GONE by 8 am!) The original crust used vanilla wafers with cocoa powder, sugar and butter. I believe the Oreo is my favorite, though. Trust me, If you love chocolate, THIS ONE IS FOR YOU!
