In a food processor, combine the pistachios, pitted dates, shredded coconut, honey, and vanilla extract. Blend until the mixture is well combined and sticky.

Scoop out tablespoon-sized portions of the mixture and roll them into balls using your hands.

If desired, roll the energy balls in chopped pistachios or cocoa powder to coat.

Place the energy balls on a baking sheet lined with parchment paper and refrigerate for at least 30 minutes to firm up.

Store in an airtight container in the refrigerator for up to one week.
