I was so excited to stumble upon this recipe from the Book of Yum; these cookies are really good! The original recipe teaches you how to make monster cookies, but I just made normal size ones which worked just as well. The photo credit here goes to Tessa Bevans.

What would be good substitutes for Sorghum and teff Flours?
Hi Jennifer,
Sadly I don’t know good substitutes off-hand. I suggest trying a all-purpose mix.
Cheers,
