About half of Great American Cookies' menu carries a seed oil - the icings and the cookie-cake base are built on canola, so every cookie cake has it, while 11 of the 20 plain cookies use palm shortening instead. The bigger issue is additives, with high fructose corn syrup in 56 of 65 items including the base dough itself.
Great American Cookies publishes a real per-item ingredient PDF, and 34 of its 65 unique statements carry a seed oil - canola in 19, soybean in 19, cottonseed in 4, sunflower in 1. The dividing line is the icing: the whole icing platform is built on a palm/canola vegetable shortening, and the cookie-cake base carries canola and soybean, so every cookie cake is a seed-oil item even though only 9 of the 20 individual cookies are. The plain doughs use palm shortening, which is not a seed oil. Nine statements still list partially hydrogenated oils, which is unusual post-2018 and may mean a stale document. Additives are worse than the oils: high fructose corn syrup in 56 of 65 including the base dough, artificial flavour in 52, FD&C colours in 26, propyl gallate in 4, BHT in 3, TBHQ in 2. Nothing is fried.
