S’mores Cookie Bars!

1. Preheat the oven to 350F then line an 8x8 inch baking pan with parchment paper and set it aside. 
2. Cream the butter, sugar, and brown sugar. Add in the egg and the vanilla and mix again. 
3. Add in the flour, graham cracker crumbs, salt, baking soda, and mix. 
4. Press half of the dough evenly onto the prepared baking sheet then remove that parchment from the pan and place in the fridge while you re-line the pan with more parchment paper and repeat the process with the leftover cookie dough. 
5. Place the chocolate bars over the dough. Spread the marshmallow fluff on top of the chocolate bar then gently flip the chilled cookie dough layer on top. 
6. Bake the cookies in the preheated oven for 25 minutes. Make sure you let the bars cool down fully before slicing.
