If you could have any cookie in the world, and your choice is without a doubt oatmeal, then you need to make these cookies. They're made with apples, which add a unique apple-pie flavor and a natural sweetness, which eliminates the need for tons of sugar.

Flax is also the star in these cookies, which boosts the fiber, filling you up so you feel satisfied after one. Oh, but the sweet cinnamon flavor and crunchy texture will have you reaching for more. And because they're under 150 calories, go ahead and have two. Actually, you might want to double the recipe, because these cookies won't last long in the cookie jar.
