Mix your wet ingredients including your peanut butter if your using it, then add your dry. until lumpy, but not blended. Add water at very small amounts at a time till it forms a stiff dough.
Knead by hand until mixed thoroughly, may need to flour surface. Form into logs 2-2 1/2 inches high, flatten to 6-7 inch wide and 1 inch thick. Bake on non stick baking sheet for 30-40 min. Remove and let cool 10 minutes. Slice into 1/2-2/4 inch slices and put back into the oven for 20 minutes or until golden brown. OR you can just roll the dough out as I do and cut into whatever shape you want and bake till golden brown.
