Preheat oven to 400 degrees.

Mix water, oil, peanut butter, and eggs until blended.

In a separate bowl, whisk dry ingredients. Add to wet ingredients and mix to form a ball. Add more flour if dough is sticky.

Roll on a well-floured surface until 1/4-1/2 inch thick. Cut with a cookie cutter or into bars. Cook for 20-25 minutes on a lightly greased cookie sheet.
