Roll out sugar cookie dough. You can make it or buy it at the store. Top with marshmallows, caramel sauce, and chocolate chips. Loosely follow directions on the sugar cookie recipe, but be ready to bake this giant cookie longer, as the middle will take a while. Remove from oven and cut slices like a pizza!
Warning - this is delicious, but if you eat too much of it, you WILL get a stomach ache. Trust me on this one.
