Add the dry ingredients to the butter mixture and mix until just combined.
Fold in the chocolate chips.
½ cup chocolate chips
Chill the finished dough in the refrigerator for at least 1 hour. You can also scoop the cookie dough onto a parchment lined sheet pan and freeze the dough for 30 minutes if you are in a hurry.
Preheat the oven to 375°. Line two half sheet pans with parchment paper.
Scoop the dough (or place frozen scoops) onto the prepared pans, about 2 inches apart. Bake the cookies for 10-12 minutes, or until the edges are lightly browned but the centers are still soft.
Remove the cookies from the oven and allow them to sit on the baking pans for 5-7 minutes before transferring them to a cooling rack.
For the S'mores Topping
Once the cookies have cooled arrange them on a half sheet pan.
Layer the broken graham cracker pieces, milk chocolate chips, and marshmallows on top of each cookie.
8-9 graham crackers, ½ cup milk chocolate chips, 1 cup mini marshmallows
Set your oven to broil.
Place the tray of cookies into the oven and broil until the marshmallows are golden brown and the chocolate chips are slightly melted.
Allow to cool before serving.
Store cookies in an airtight container for 2-3 days.

Notes
These are also really fun to make in a mini muffin pan. If you decide to do this, bake the cookies first, and then top with the graham cracker, a square of Hershey's Chocolate, and ½ of a regular sized marshmallow. Then broil until the marshmallow is golden brown.
