Unfortunately not enough thought is put into the toppings to ensure they're gluten free. I've noticed quite a few times and let them know and they admit they did not realize something wasn't GF until I mentioned it. Some examples are rice krispies, oat toppings, and rainbow belts. They have been good about using GF cookies for Oreo donuts and leaving graham crackers crumbs off on GF days in the past. I love their staff and their donuts are absolutely delicious, just not safe enough for anyone with celiac.
