I need to make cookies for a friend's grandma's 100th birthday party. (I know!) I will be delivering them to said friend a day or two before the party, and she will be carrying them on the plane. So, I need a recipe that a) is festive b) is relatively traditional (Grandma is 100% style, 0% fad) c) is travel-worthy and d) won't go stale right away. Making cookies Thurs. a.m.... Thanks in advance for the help, SEaters!
