I love these best with Skor toffee bits but they stopped selling them in grocery stores years ago. I'm lucky enough to have a "connection" and my friend's husband ordered them through one of their food suppliers. You can buy them online here , they are a little pricey, but so worth it. If you keep them store in your freezer, they will stay fresh for a really long time. I have used the Heath toffee bits, and they cookies are still delicious, I just prefer the Skor bits.
