Oldie but goodie: Sourdough Cookies!

OK, so I know there's been some discussion here about the best sourdough cookie recipes ... but not for awhile.  I need to make some cookies for kids coming over tomorrow afternoon for a class at our place.  Suggestions?  I've done a peanut butter recipe I found in the forums that was posted awhile ago -- it was good, but not a knockout, so I'm jonesing for others to try.

Thanks!
