Preheat oven to 350 degrees and prep your cast iron skillet with baking spray.
Take one cookie dough roll and spread it out into the bottom of the skillet.
Place your Oreo cookies and Reese's peanut butter cups along the edge of the cookie dough, alternating between the two and leaving the center of the cookie dough empty.
Combine the chocolate chips, marshmallows, and graham crackers, then add the s'mores mixture to the center of the cookie dough.
Roll out the second tube of cookie dough and place it on top of the skillet, then press the edges together (like a pie crust).
Bake the skillet cookie for 25-30 minutes or until golden brown.
Once baked, let sit for 10 minutes before cutting into the cookie
Serve with ice cream, whipped cream and chocolate fudge sauce.
Enjoy!
