It's always dessert season, so I can't say there is one in particular for fall.
I'm gluten free these days so dessert options are usually cheesecakes, halva, and variations on chocolate chip cookies. Here's a gf tahini chip recipe that was bomb.
Note to self, come up with a decent gf dough for apple pie.
