In a mixing bowl, stir together first 6 ingredients.
Combine dry ingredients and add to peanut butter mixture. Stir until well blended. If dough seems very soft, put it in the refrigerator for about 30 minutes. Otherwise proceed as directed.

Let the cookies cool completely before serving. They are much better when completely cool.
