Cookie Madness is the only flavor that is NOT certified gluten free (This includes the swirl of cookie madness and whatever it is next to).
The rest of the 13 flavors are all certified gluten free. These yogurts are also safe from cross contamination.
I would not get any toppings if you have celiac as all toppings are cross contaminated, including the ones in the back.
Employees have a book of all of their toppings/yogurts with all of the ingredients for any other allergy/sensitivity.
— Somewhat
