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

Soak the pitted Medjool dates in hot water for 8 to 10 minutes to soften them.

Process the old-fashioned rolled oats in a food processor for about 30 seconds until mostly broken down but still textured.

Combine the soaked dates and nut butter with the oats in the processor and blend until a sticky dough forms.

Adjust the dough consistency as needed, adding more oats or nut butter if too wet or crumbly.

Shape portions of the dough into balls and flatten them on the baking sheet.

Bake the cookies in the preheated oven for 10-12 minutes until lightly golden around the edges.

Cool the cookies on the baking sheet for about 10 minutes before transferring them to a wire rack.
