A perfect recipe for anybody who likes toffee. The cookies have a wonderful crisp texture and overall toffee flavor while the chunks of toffee in the cookie itself are to die for. Skor bars work just as well, though I suggest using whole bars and crushing them over the bagged toffee bits since the chocolate makes a big difference. When you crush them up try to leave pieces of all different sizes, from crumbs to a few really big chunks and lots of in-betweens. These cookies also do well with 1/2 cup walnuts, chopped and added with the toffee.
