Process prunes until small pieces are formed. Remove from processor.
Process nuts until fine meal forms. Add prunes and agave nectar and process again, until crumby loose dough forms.
Line a 8x8 inch square dish with parchment paper. Transfer the prune-nut mixture and pack it evenly to the bottom of the dish. Refrigerate, until you are ready to pour the cheesecake better on top.
For the matcha cheesecake:
In a blender, combine soaked, rinsed and drained cashews, coconut oil, coconut cream, Agave nectar and matcha powder.
Blend until smooth and creamy.
Pour cheesecake batter over the crust and freeze for 4 hours.
When ready to serve, cut into 16 squares. Keep frozen for up to 4 weeks.
