Chocolate Chip Cookie Dough Cheesecake Bars

Ive been meaning to make this for a long time and it wasnt until I saw it again on this blog: Life in a Peanut Shell, (yet altered like I always do) that I was like, "OK, I have to do this." I love cookie dough and I love cheesecake, so I knew I'd like this. This type of dessert to me is like a heaven. My mom just about died. She usually never comments about anything I make since Im baking all the time and messing up her kitchen and she's just sick of it, but when she tasted this, she was just like "oh my gosh, oh my gosh, this is so good." She even said that I need to mention on my blog how much she likes it. Bake or Break is where the recipe comes from. I altered it a little. I made an oreo crust instead of a graham cracker crust and i replaced half of the chocolate chips (in the cookie dough) with m&m's and decorated the top w/ m&m's as well (for New Years).
