Place all ingredients except for the chocolate chips in a food processor, and blend until well combined. Alternatively, you can just put everything into a big bowl and mix well with a wooden spoon.
Add in the chocolate chips and pulse/mix until well combined.
Transfer the mixture into a bowl, and refrigerate for about 1 hour.
Using a 1 1/2 tbsp cookie scoop, measure out the mixture and roll into balls and place in airtight container and store in the refrigerator for 1 week.
Notes
*I used chunky peanut butter because I enjoy the pieces of whole peanut.
You can also add other ingredients such as flax, sunflower seeds, dried cranberries or cherries.
