Soak the raw cashews in warm water for a couple of hours. Drain and rinse.
In a blender, combine the soaked cashews, frozen cherries, cacao powder, aquafaba, oat milk (or almond milk), date syrup (or agave syrup), and cherry liqueur (if using). Blend until smooth and creamy.
Transfer the mixture to a bowl, cover, and let it sit in the fridge for a couple of hours for optimal consistency (optional).
Pour the chilled mixture into an ice cream maker and churn according to the manufacturer's instructions until it reaches a soft-serve consistency.
Add cacao nibs during the last few minutes of churning to distribute them evenly.
Transfer the ice cream to a lidded container, sprinkle some extra cacao nibs on top (if desired), and freeze for at least 4 hours, or until firm.
Scoop and serve the chocolate cherry cashew ice cream. If desired, top it with some frozen cherries, or some chocolate sauce and vegan whipped cream Enjoy!
