In bowl of food processor, pulse together prunes, almond butter, maple syrup, flaked coconut, chia, cacao powder, cardamom, and cinnamon. When mixture is uniform, add in oats, pistachios, and cacao nibs. Pulse a few more times until these last ingredients are just combined.

To bowl, transfer mixture and squeeze it together with your hands. Using 1 Tbsp (15 mL) cookie scoop or measuring spoon, scoop individual balls of mixture and roll in your hands. Place in parchment-lined glass container, cover with lid, and refrigerate until about an hour before serving time.
