Newman's Own makes an organic Oreo-type cookie, I believe (haven't tried it).
I did buy a box of organic chocolate wafer cookies once, and when I wanted ice cream or a milkshake I would make a banana smoothie with cocoa powder and a little sorghum, and then throw in a few cookies. It tasted GREAT and overall, wasn't as bad as a real milkshake, even if the food combining isn't great.
