Peanut Butter Cookie Bars are our favorite soft, chewy peanut butter cookies in bar form then slathered in a layer of creamy peanut butter and topped with decadent Butterfinger chocolate frosting! This Peanut Butter Cookie Bars recipe is what dreams are made of.
*May substitute smooth peanut butter but I love the extra crunch. **I have found the easiest way to evenly spread cookie dough is to top the dough in the pan with a large sheet of parchment paper (larger than the size of the pan) then roll it out using a rolling pin over the parchment paper until even.
