I shared these amazing cookie bars over at Lolly Jane last month and its almost summer time, so I’m thinking all things s’mores and wanted to share them with you too!

The cookie bars start with a peanut butter cookie base, which I just barely altered from my peanut butter blondies recipes, you’ll then mix in some chocolate chips and some Reeses’s peanut butter cups and bake. Top it with marshmallows and return to the oven for just a minute to allow the marshmallows to get that perfectly golden toasty edge that we love in s’mores. Slice them up carefully and you’re ready to serve!
