Grease 12-inch pizza pan with nonstick cooking spray. In pan, break up cookie dough. In bottom of pan, evenly spread cookie dough to form crust. Bake 12-17 minutes, or until light golden brown.
Sprinkle marshmallows, peanuts and chocolate chips evenly over crust. Bake 8-10 minutes, or until toppings are melted. Drizzle with caramel topping. Cool completely, about 1 hour. Cut into wedges.
