Preheat oven to 350 degrees F. Line a baking sheet with parchment paper.

In a small bowl, combine flaxseed and water and let sit in the refrigerator for at least 15 minutes.

In a medium mixing bowl, whisk coconut oil, peanut butter, maple syrup, vanilla and flax eggs until smooth and creamy.

In a large mixing bowl, mix oats, chocolate, baking soda and cinnamon until well combined.

Add wet ingredients to the dry and stir to combine until mixture is sticky.

Using a spoon or ice cream scooper, drop 2-inch rounds of dough onto the baking sheet so cookies are a few inches apart. Sprinkle course sea salt over tops of cookies. Bake for 15 minutes, or until golden-brown and somewhat firm to the touch.

Remove from oven and let cool on baking sheet for a couple minutes before transferring to a wire rack to cool. Option to sprinkle a few more flakes of sea salt over top. Let cool completely before serving.
