As for the twix recipe, f you like shortbread, these are for you, they are probably a little less sweet than the traditional twix, but it was really easy and a very tasty cookie. There are ton of recipes out there, but I found this one on insidebrucrew.

Chocolate Layer: 2 c. chocolate chips, 2 T. shortening
Crust: Crump all ingredients together (I used a fork, but it still looked like this...
Bake for 350 degrees for about 18 minutes.
Caramel Layer: Combine all the ingredients in a saucepan. Bring to a boil (this happened quickly for me) and stir CONTINUOUSLY for 5 minutes (it will burn quickly if you don't do this). Remove from heat. Stir until the mix starts thickening (took just about a minute for me). Pour over the crst and let it cool some.
