Peel bananas, wrap in plastic and freeze overnight. Soak cashews in water to cover for 1 hour. Drain and rinse. Soak dates in water to cover until soft (about 1 hour). Drain off soaking water and save. Combine cashews, dates, date soaking water, vanilla and 1/2 cup filtered water in blender and process until smooth. Cut frozen banana into 1-inch pieces and add to blender. Add water as needed to make a smooth, creamy mixture.
