I used to send cookies and pumpkin-cranberry bread to my late brother and his family via Priority Mail for Christmas. And yes - freezing cookies for 24 hours before shipping can help them stay fresh.

Maybe send her a personal popcorn popper for the microwave and some fancy popcorn kernels? I gave both as a Yankee Swap gift at Christmas a couple of years ago - it went over well.
