To Help market Cottonseed Flour the Golden Rod company use to have recipe contests. The winner of one of these was Golden Rod Oatmeal Cookies, recipe is in this old advertisement.
Believe it or not Cottonseed use to be a viable source of flour which had no gluten but it had more protein and fat compared to wheat flour. During the first world war there were shortages all over so this was seen as a viable option , perhaps to keep your flour for bread and cakes and biscuits you could use cottonseed flour.
I can find cottonseed flour and cottonseed meal online for sale but it looks as if it is mostly used for fertilizer.
