I don't know about s'mores pie, but the way we do s'mores is take milk-free chocolate chips and push 4 or 5 into the marshmallow before you toast it.  As the marshmallow is toasted, the chocolate melts and the soft chocolatey marshmallow is fabulous between two milk free graham crackers.  My daughter can pretty much be a regular kid at the campfire with this method.

Subject: S'mores pie?

Dear Friends,

My son had a milk-free s'mores pie at summer camp that he absolutely loved.
However, the baker has since left, taking the recipe with her.  I've spent
considerable time hunting for a recipe in my cookbooks and on the internet,
but can't seem to find what he wants.  Does anyone have a suitable recipe
that you'd be willing to share?  (I'll only put the recipe on my web site if
you give me permission.  My primary goal is to give my son a treat.)

Thanks,
--Beth Kevles
