We don’t buy commercial cookies either. Most have trans fats up the wahoo in them. I make them from scratch. Better anyway. That way I can reduce the salt a bit if I want or lower the fat a little.
Out of three handy cookie packages I picked up and looked at, one has zero trans fat, one does not say (probably also has none, because of modern listing requirements), and one (dollar store cheap) shows trans fat at a tiny fraction of the total. A far cry from the Crisco cookies of old.
