Easy S'mores Bars Cookie recipe with loads of graham crackers, chocolate, and marshmallows!
SNAPPY TIPS: Instead of flattening the top cookie layer on a piece of parchment paper, you can take small amounts of dough and flatten with your hands then place on top of marshmallow fluff covering as much of the marshmallow as possible. Don't worry if the marshmallow is not covered 100%!
SNAPPY SUBSTITUTIONS: If you have to, you can substitute king size chocolate bars or chocolate chips. The marshmallow fluff can be difficult to spread over chocolate chips though. Do NOT substitute regular marshmallows for the marshmallow fluff. Marshmallows will melt in the oven and the cookie bars will not turn out well.
