Chocolate Pecan Cheesecake Bars

Ok, these bars are delicious. Chocolate. Cheesecake. Pecan pie. If that doesn't get you salivating, I don't know what will. I cut the originally recipe down because it's really, really rich. I cut mine into very small bars because a little goes a long way. These are best the next day, so make sure you plan ahead if you want to serve these.
