Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.

Combine 2 cups of oats with ½ cup of unsweetened cocoa powder in a large mixing bowl.

In a separate bowl, whisk together ½ cup of honey (or maple syrup) and 1 large egg (or prepared flax egg).

Pour the wet mixture into the dry ingredients, and mix gently until combined.

Drop small mounds of dough onto the prepared baking sheet, spacing them 2 inches apart.

Bake for 10-12 minutes, keeping an eye on them as they should be set but still soft in the center.

Let the cookies cool on the baking sheet for about 5 minutes before transferring to a wire rack.
