Salted Caramel Brownie Cookie Bars

So its summer and since I have some free time, I decided to make these. After spending a few weeks in California over Christmas, I was inspired by everything being so decadent over there. 

And out came the idea inspired by a 'slutty brownie' which is a chocolate chip cookie base with oreo cookies in the middle and a layer of brownie on top. But since I didn't have any oreos or anything similar, I decided to fill it with salted caramel. And thus, I give you the salted caramel slutty brownie.
