Chewy Chocolate Chunk Cookie Bars

"These double chocolate cookie bars are probably the best you will ever try. They stay chewy in the middle and ever so slightly crispy around the edges (like the perfect cookie) and they are so easy (and quick) to make. Eat them like a regular cookie, or serve them warm with vanilla ice cream for the perfect cookie treat! These foolproof cookie bars are a take on my very famous chocolate chip cookies. But served in bar form like my ultra-famous brownies! I've used dark and milk chocolate for these bars as well as using some chopped up bars of chocolate and some chips. It's just that I had some bits of chocolate leftover, so tossed it all in. No such thing as too much chocolate in your cookie bars! "
