Add cashews to food processor and pulse until they're broken up into small bits. See below photo. Don't process too long – we don't want a flour consistency! Empty cashews into a large bowl and set aside.
Add dates to the food processor and blend until they form into a big, sticky ball. This usually takes 20-30 seconds in my processor.
Add the date paste to the bowl with cashews, then add chocolate chips, maple syrup, coconut milk, and a pinch of sea salt. Use your hands to mix it all together. Once everything is well-combined, scoop out small handfuls and roll them into balls. I like to make mine about 2 tablespoon-sized.
If desired, sprinkle matcha onto finished energy balls.
