Drain dates and save water. Blend dates, pine nuts and vanilla in food processor or blender for 3 minutes or until smooth, adding a little soak water (from dates) if necessary. If desired, save remaining date water for use as a liquid sweetener for up to 6 weeks. For best texture, refrigerate frosting at least 6 hours or overnight before using. For whiter cake, cover with a layer of moist shredded unsweetened coconut after frosting.
