Add the raisins, cashews, cocoa powder, vanilla extract, salt, and cinnamon to a food processor and pulse until the mixture has the consistency of coarse sand.
Remove the blade, scoop portions of the mixture with your hands, and roll each portion into a ball.
Chill the bites for 30 minutes before serving. Store them in an airtight container in the refrigerator for up to one week.
Notes
The mixture should hold together when pressed; if it feels crumbly, pulse briefly a little longer.
