Salted Caramel Nut Bars

Why I Love This Recipe
This recipe is one I got from my aunt Laural. She says it's a lot like the caramel nut bars she has had from a bakery in Stillwater, OK. You cut them in small pieces, so one batch makes several food gifts and has been a hit with everyone I've shared them with.
