These links to "biscuits," look like cookies to me.

I, a US native in the northern plains, am positive that my great grandmother (whom
I knew), was making biscuits way before 1960. So whatever you read, it seems to have
been a propaganda piece put forth by KFC.

More a "southern thing," that may be; I wouldn't know. I do know that biscuits and gravy are very
popular and available here in the North, and many, many diners offer biscuits alongside regular
entrees.
