Place oats, peanut butter, maple syrup, vanilla, and salt in a food processor and pulse until combined, about 10 pulses. Scrape down the sides of the bowl. Add chocolate chips and pulse a few times to coarsely chop.

Taking small spoonfuls of the mixture at a time, use your hands to form it into 1-inch balls. I find that using both the palm of my hand and fingertips to squeeze the mixture together works best to shape the balls.

Store in the refrigerator.
