Preheat oven to 350 degrees F.
Add half of your cookie dough in the bottom of a 10-inch skillet (this can also be made in a 9x9 baking dish but baking time will differ).
Drizzle caramel and top with half of the pretzels.
Arrange the caramel pieces and top with another layer of cookie dough, pretzels and caramel.
Bake for 20-25 minutes or until golden on top.
Let cool for 10 minutes before digging in.
If you prefer a cool cookie then cool completely!
