Preheat oven to 325°. Lightly coat an 8 x 8-inch baking pan with nonstick cooking spray.
In a small bowl, combine flours, baking powder and chocolate chips. In another bowl, using a hand mixer, combine egg, sugars, water, oil, vanilla, butter and peanut butter. With a spatula, gradually fold flour mixture into peanut butter mixture.
Spread mixture evenly into baking pan. Bake for 30 minutes, or until the top of the bars looks dry. Cool in pan on a wire rack, then cut into 2-inch squares.
