Peanut Butter Cheesecake

The first time I served this peanut butter cheesecake recipe, my friends all went wild over it. They were surprised when I told them the crust is made of pretzels. The pairing of sweet and salty, creamy and crunchy, plus peanut butter and chocolate, left everyone asking for another slice.  This is a large cheesecake 10" x 10" x 3".   It weighs approximately 6 pounds and serves 12-16.   I need at least 2-3 days to make this cheesecake, one for baking and one for chilling.
