Preheat oven to 350 degrees F (175 degrees C). Line a 9×13 inch baking pan with aluminum foil or parchment paper, and spray with vegetable oil spray. In a large bowl, stir together the dry ingredients, oats through walnuts. In a smaller bowl, thoroughly blend the remaining liquid ingredients. Pour the liquid mixture into the flour mixture, and mix by hand until the liquid is evenly distributed. Press evenly into the prepared baking pan. Bake 25 to 30 minutes in the preheated oven, or until the edges are golden. Cool completely in pan, then turn out onto a cutting board and cut into bars.
