Preheat oven to 200 degrees and line a jelly roll pan with parchment or wax paper. Be sure to grease that as well. Set aside.
Add marshmallows to a large bowl along with butter. Melt in 30 minute increments until puffy. Stir well to combine and add the graham cracker crumbs and rice krispy cereal. Stir again.
Press mixture into prepared pan. Spread marshmallow fluff all over in a thin even layer.
Top with chocolate chips and put in the oven for 5 min to melt them. Spread all over and let it cool for 5 minutes.
Grease your hands and use the parchment/wax paper to help roll it all up. Refrigerate for 30 minutes, slice and enjoy!
