Using a spatula, add dry ingredients to the wet 1/2 at a time. Mix until JUST combined. Fold in 1/3 c chocolate chips. Loosely cover the dough in plastic cling. Place dough in the fridge to chill for one hour.
Preheat the oven for at least 30 minutes. Line a 9X13 baking pan. Roughly divide the chilled cookie dough into thirds. Reserve about 1/3 for topping. Evenly press 2/3 of the chilled dough along the bottom of the prepared baking pan.
Scoop even dollops of marshmallow creme, or fluff along the chilled dough. Top with 1 cup of semi sweet chocolate chips. Top the marshmallow creme and chocoate with roughly crushed pieces of graham crackers. Top everything with the remaining 1/3 of the chilled dough.
