White macadamia nut will always be number one, but any cookie that involves peanut butter and/or chocolate is a very close second. We can't have chocolate peanut butter Oreos in the house anymore because I will eat the entire pack faster than the Flash can run.
Also my mom recently made dark chocolate cookies with butterscotch chips and OMFG they were so good. Which reminds me, I should probably go beg her to make more (I'd do it myself but I can't be trusted around ovens, and no, I will not be elaborating on that).
