Roast hazelnuts in pan for 2 minutes on low flame, switch off the flame and let it cool down. Take wafer shells in plate.
Now take one wafer shell, fill it with nutella and keep one hazelnut piece in the centre of it. Take another wafer shell and fill it with nutella and keep this on the already filled wafer shell with hazelnut. Keep it in tray. Similarly prepare all the shells and keep in a tray. Keep the tray in deep freezer for half an hour.
Meanwhile roughly chop milk chocolate in microwave or by double boiler method. Stir well to melt chocolate completely. Make sure no chocolate lumps remain. Add cashew nut pieces and mix well.
Now take out the tray from the deep freezer. Dip one prepared shell ball in melted chocolate cashew nuts mixture. Properly coat from all sides and with the help of a fork keep in a plate. Similarly coat all the shell balls with the chocolate mixture and keep in a plate. Keep the plate in deep freezer for a minute.
After a minute remove plate from the freezer and with the help of a knife gently remove extra chocolate if any. Cover ball with wrapping paper and place it in paper cups.
Enjoy the homemade Ferrero Rocher Chocolate!
