I have a cookie jar just like that sitting on my counter.
I fill it up with oreos but the darn things vanish almost instantly yet no one claims to have eaten them all (gnomes must invade the kitchen at night I guess =p )
Anyway salt dough cookies would work perfect for what you want .
They won't look like chocolate chips cookies though , more like gingerbread . Use a jar lid to cut them out and they will look almost like ginger snaps .
You won't have to worry about anyone eating them ..drunk or not they may take a bite but they will spit them out .. taste like pure yuck .
They keep for a long time if your humidity is low even if you don't varnish them. http://www.razzledazzlerecipes.com/christmasfun/kids.htm
the recipe with the cinnamon and nutmeg is really nice ... they smell great
