Process all the ingredients to a semi-sticky dough ball. Trust me; you’ll have to be patient as the dough comes together. I’ll take a few minutes.
Remove the dough ball from the food processor and roll the dough flat on an oiled surface. We use oil on wax paper or parchment paper to keep the cookies from sticking. Wetter cookies will be stickier. If the dough is sticking to your fingers; it’s too wet.
Cut the cookies out. Any shape is A-OK. I suggest not cutting them in squares of you plan to toss them to the dog for catching. Ever had a corn chip “hook” sideways in your mouth? Those edges will cook harder than the center and will likely poke the inside of the dog’s mouth.
(Optional). Use a fork to score the cookies for more even cooking. They will not rise; there’s no soda or yeast in these cookies.
As round shapes go, there are always those bits and parts left from cutting the cookies. Stack the cut and scored cookies up and gather all the bits and pieces. Roll them back up and cut more cookies out. Keep going until all the dough is cut out into cookies.
Place them on the cast iron griddle (the flat side). You could add some oil but it’s not usually necessary unless your cookies are a bit sticky.
Bake the cookies in the oven for about 30minutes. After about 20 minutes you could give them a turn, but this is not necessary.
After they are baked, pull them out for cooling. DONE!
