Combine ingredients (mix egg replacer according to the product instructions.) Drop onto cookie sheet and use a fork to flatten and make the traditional peanut butter cookie waffle pattern. (If you want to make them look different than peanut butter cookies, use a slotted spoon or other tool to make a unique pattern of your own.) May sprinkle with sugar before baking.
Bake for 15-20 minutes at 350 °F. Cool completely before eating (they crumble when hot!)
Sunflower seed butter can be used in place of soy butter. Commercially available sunflower seed butter may contain soy. If avoiding soy, you can make your own Sunflower Seed Butter using safe sunflower seed kernels.
