Press the base mixture into a mold and refrigerate until set.
Soak cashews in water, blend them until smooth, then add coconut cream, lemon juice, and maple syrup to create the cheesecake cream.
Pour the cream over the base and smooth out the surface.
Refrigerate for at least 4 hours to set.
Slice into pieces for serving.
