This cookie is bananas.  Half chocolate chip, half brownie cookie.  Now that I know how easy it is to make two different doughs and roll them together into one perfect cookie, I think the possibilities are endless, don't you?  WHAT UP, CHRISTMAS COOKIES?!  I'M TALKING TO YOU, BOO.  Sorry I don't know what that was.  I used this recipe but I cut the chocolate chip cookie dough in half.  I've written the word "cookie" way too many times in this post.  Cookie.
