In a food processor, combine the Medjool dates, cocoa powder, peanut butter, sea salt, and vanilla extract if desired. Pulse until a sticky dough forms.

Roll the mixture into compact balls, aiming for a size similar to a golf ball. You should create about 10-12 balls.

Chill the balls on a parchment-lined plate for at least 10 minutes to firm up.

Serve immediately or store in an airtight container in the fridge for up to two weeks or freeze for longer storage.
