Here is the recipe

Here is what they look like while they're being made.

Some helpful tips:
* I find that melting the caramel in the plastic frosting bag makes it much easier to drizzle neatly as well as not getting sticky, hard to clean off caramel off of spoons and cups.
* Use good caramel. I get mine from a baking supply store near me. I am sure you could use those little plastic wrapped square thingies, and it would probably be just fine, but I think the texture would not be as smooth as the caramel that is made just for this purpose.
* What makes the cookies and bars taste so remarkable is the use of really good vanilla. It's an investment that's well worth it.
