I was told that they are baked on separate trays but in the convection oven at the same time as the regular cookies.
They have AMAZING gluten free cookies that are baked completely separate from their other cookies. They sell them in bags. Best GF cookies ever.
To my shock Hope's offers certified gf cookies! They're prepared separately and baked in their own oven. They are out of this world fantastic! A must go to for celiacs!
