I have to agree with all the selections so far, with the exception of peanut butter. I like peanut butter, just not in a cookie.
Also, is there anything better, does anything smell better, taste better, feel better in your mouth than warm out of the oven cookies ? Yum. I've even eaten them downright HOT. Warm cookies are softer, chewier, gooier, and the flavors meld onto your tongue.
