Preheat oven to 350F. Line a large baking sheet with parchment. (Optional: trace a circle onto the parchment, flip so the circle is facing the baking sheet. You should still be able to see what you drew.)
-
Use your hands to form the cookie dough into a large circle, about ¼" thick.
-
Bake in preheated oven for about 20 minutes or until the cookie is a deep golden and the center is no longer gooey. Remove from oven. Turn on your broiler and move an over rack up to the top if necessary.
-
Sprinkle graham crackers evenly over the cookie. Top with chocolate pieces and marshmallows.
-
Return to the oven for about 5 minutes, until the marshmallows are toasted.
-
Serve warm! Slice it like a pizza!
