My mother in law informed me of deNotre Cuisine located in Big Timber, MT. They are a deli and pastry shop that sell homemade gluten free scones. I never thought I'd hear about this in Big Timber! I haven't tried them but was told they are delicious. They are located at 104 McLeod St. Check out their webpage for contact information.
I can't wait to give them a try, if you beat me to it let me know what you think.
