Hannahmax Baking. I tried both the Sea Salted Peanut Butter flavor (shown here) as well as the Cinnamon Sugar, and both were delicious. Their tagline is "Tastes like a Cookie, Eats like a Chip", which is true: these are super thin, extra crunchy treats. Plus they're made from hormone-free butter, cage-free eggs, and contain no GMOs.
The only problem is that I found these on a clearance endcap in the Grocery Section for $1.98 bag (down from $3.99 each). The sale price was great and all, but now I can't find them at Target anymore. I think these cookies were part of Target's latest Made to Matter promotion which hit stores 5-6 weeks ago. Hopefully Target will stock these regularly, but if not, it looks like they are carried at many other stores (including Safeway, Fred Meyer, Whole Foods, Vons, and Raley's).
