Ultimate Rich Peanut Butter Marshmallow Crispie Brownie Bars

"These bars are seriously ridiculous because the are easy and SO rich. When I bring them for co-workers, they go biserk. Kids love them and grown men have been reduced to nothing but silence and eye rolling. Starts with a plain boxed brownie mix."

<p>I live in Southwestern Missouri and work for the local Public Works Department. I love my job, it's interesting and I find that I laugh alot when I am here. We often talk about food here and I really like to bring things in to share when I have time. I have two children, &nbsp;a 12 year old son and a 6 year old daughter. My son is the pickiest eater on the planet and my daughter will eat almost anything you put in front of her. My all time favorite cookbooks are community collection types...like chuch collections, ladies groups, etc. They usually have everyone's tried and true dishes so you know it will be outstanding. My favorite dish to cook varies, sometimes it's lasagna, sometimes cilantro chicken enchiladas, meatloaf, whatever I am craving at the moment. I am known for my cheesecake and these ridiculous brownie, marshmallow, peanutbutter krispie bars. I am addicted to Pinterest.</p>
