Sorry I can't help you with your cookie request, but as someone who posted a lost cookie request over the weekend I can empathize. Ever since my mom died I've been telling people to talk to their loved ones about these kind of things--big things like funeral plans and their estate, but even smaller things like recipes that aren't written down or where they keep their special dish for the Thanksgiving wild rice. It's hard, but you will be happy you did! It's actually the little things like the lost recipes or things we can't find that can be the most frustrating. Good luck!
P.S. I do have one success story from years ago. When my husband's grandma died she left behind an index card with the recipe for my husband's favorite Christmas cookie. However, some of her writing we couldn't read and parts of the recipe conflicted. The first time I tried to make them I added double the amount of required shortening/butter and had a disaster on my hands! I was ultimately able to find a very similar recipe on line and have been able to successfully re-create my husband's grandma's cookies. Maybe he's just being nice, but he says mine are even better than grandma's. So I wish you the same success.
