Combine the frozen cherries, Greek yogurt, milk, ice, hemp hearts, almond butter, cocoa powder, vanilla, and a pinch of salt in a blender.
Measure the chai spice: mix the ground ginger, cinnamon, cardamom, cloves, and allspice; add half of this chai spice mixture to the blender.
Blend on high until completely smooth and creamy, stopping to scrape the sides if needed.
Taste and adjust: add more chai spice to taste or 1–2 pitted dates if you prefer a sweeter smoothie, then blend briefly to combine.
Pour into glasses and top with hemp heart sprinkles, a few frozen cherries, a light dusting of chai spice, and chocolate curls if desired.
