In a food processor, process the dates and peanuts until they begin to form a paste. Add in the peanut butter and continue to process until a dough begins to form. Next, add in the chips and pulse a few times to combine.
Line a 9x5-inch loaf pan with parchment paper or plastic wrap and spoon in the mixture. Press firmly in the loaf pan, until about ¾-inch thick.
Refrigerate:
Refrigerate for 1 to 2 hours until firm. Lift up the parchment liner, remove from the loaf pan, and cut into 6 bars. Wrap individually and store in the refrigerator for up to a week.
