Preheat oven to 350°F. Line a 8x8 inch baking tray with aluminum foil. Coat the foil with cooking spray. In a large bowl combine the peanut butter, egg whites and molasses. Mash the peanut butter into the eggs and molasses with the back of a spoon until a smooth mixture forms. Add the oats, Amaz!ns™, flax, pumpkin seeds, sesame seeds and pumpkin pie spice. Mix well and transfer to the baking dish. Press into an even layer with a rubber spatula. Coat the top with a light coating of non-stick spray and spread out into an even layer. Bake 40 to 45 minutes until the oats are golden and firm. Cool completely before cutting into 8 bars.
