In a food processor, process oats until a fine powdery, flour like consistency. There may still be some graininess here and there.
Add dates, peanut butter, salt, maple, and vanilla and process until combined and dates are broken down.
Add in milk 1 tablespoon at a time and process until you get a thick, smooth dough-like consistency. Mine formed a ball in the food processor.
Roll into balls and if desired, press with a fork into cookies.
Refrigerate for about 20 minutes before eating.
