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

In a large mixing bowl, add rolled oats, nut butter, honey or maple syrup, and cocoa powder. Mix until fully combined.

Use a tablespoon to scoop portions and drop them onto the prepared baking sheet, spacing them about an inch apart.

Flatten each cookie slightly with the back of the spoon, then bake for 10-12 minutes.

Allow the cookies to cool on the sheet for about 5 minutes, then transfer to a wire rack to cool completely.
