Preheat oven to 350°F (177°C). Line a large cookie sheet with parchment paper or a silicone baking mat.
Add oats to a medium mixing bowl. Drizzle melted coconut oil evenly across. Using a spatula, stir the mixture briskly for about 20-30 seconds, stopping a few times to scrape the sides of your bowl, until most of the oats look slightly moistened with coconut oil. The oats only need a little oil so they should not look fully wet.
Add in the maple syrup. Mix with your spatula until the oats are evenly coated in syrup and the oats start to clump together.
Using a 1 tbsp cookie scoop, pack 1 tbsp of oat mixture into your cookie scoop. Release onto your prepared baking sheet. The mixture will be loose and not fully hold together. Use the back of a metal spoon to press and shape the mixture until it becomes a thin round disk (between 3/16 and 1/4 inch thick). See photo in post for reference. Repeat with remaining mixture, spacing each about 1 inch apart. If your mixture is too sticky, you can wet the spoon lightly with water.
Bake the cookies for about 10-12 minutes or until the surface is lightly browned. The longer you bake, the crispier the cookies will be but you do want to make sure the edges don't get too dark.
Remove cookies from oven but don't attempt to move them from the baking sheet until they are fully cooled and set. If you try to remove them while they are still warm, the cookies will fall apart. Once they are cooled, the cookies will be fully set and should peel off the parchment paper/silicone mat easily.
Notes
The longer you bake the cookies, the crispier they will be. So if you want a very crispy crunchy cookie then I recommend you bake the cookies until they are lightly browned all across the surface and the edges are a darker brown.
This recipe works best with quick oats. Regular oats will take longer to cook and need more oil and maple syrup. You can also run regular oats in a food processor until they become the size of quick oats.
