My particular favorite cookie is oatmeal cherry chocolate chunk, but I've got a horrendous sweet tooth.
Mmmmm.....that sounds awesome. My favorite cookie is tied between white chip macadamia nut or those delicious wafer thin cookies that are kinda chewy and are dipped in chocolate and caramel. I wish I knew what they were called! I just know they're delightful and they come in those assorted cookie tins.
I'm not a huge fan of chocolate in general- I prefer sweet and chewy candies like jelly beans and swedish fish. If I want chocolate, it generally has stuff in it- caramel, coconut, pretzel, peanut butter, etc.
EDIT: omg omg I found them!!
They are called lace florentine cookies. Mmmmmm. Google also reminded me that they are sometimes stacked and made into sandwiches with a creamy mashmallowy filling. Those are also amazing.
