In a food processor or blender, process the dates until they’re broken down and form a paste-like consistency. Stop the processor a few times to scrape down the sides.
Add the chocolate chips and pulse a few times to break down and combine. Place mixture in the fridge for about 15 minutes to allow it to firm up slightly.
Roll the dough into 12 bite-sized balls. Next, flatten each with a fork or the palm of your hand, fixing any larger cracks along the edges with your fingers.
Top with additional finely chopped peanuts and chocolate chips, if desired. Store in the fridge for at least an hour before serving to allow the cookies to firm up.
