http://thecrepesofwrath.wordpress.com/2009/04/17/samoas-bars/F you, that recipe. False hope giver!
I just made some (sans choco-bottoms because it seemed overkill and I was being lazy)...

really they're nothing like Samoa's at all. I added a tablespoon+ of lemon juice to the cookie dough to spice it up, but in the end I'm not sure why they don't just tell you to get one of those pre-made sugar cookie packs from the grocery store and spread that out. Not to mention the cookies themselves are just way too thick, I'd cut the cookie recipe by 1/4th at least. Further, way too much caramel (cut it down to like 8 ounces, instead of 12) and anytime anyone tells you to use chocolate chips for anything other than in chocolate chip cookies, you punch them right in their face where they stand.
In the end, not horrible to eat because I mean, it's chocolate and caramels and junk, but not even close to a Samoa. This has me all fired up though to do a sheet shortbread cookie and try my modifications to get it right - I THINK I CAN CRACK THE CODE!
tl;dr nomnom cookies not taste like girl scouts but fatty gon' eat nem anyways.
