Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.

In a large mixing bowl, combine rolled oats, cocoa powder, nut butter, and maple syrup until a thick dough forms.

Scoop cookie dough onto the prepared baking sheet, flattening each scoop slightly.

Bake for 10-12 minutes until edges are firm and centers are slightly soft.

Cool on the baking sheet for 5 minutes, then transfer to a wire rack.
