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

In a large mixing bowl, combine rolled oats and cocoa powder until well blended.

Add nut butter and sweetener to the oat mixture and mix until fully combined.

Scoop and shape the cookie dough onto the prepared baking sheet, flatten slightly.

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

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