Firstly take digestive biscuits and crush it finely in mixi jar.
Take out in large bowl. Add Nutella, milk and chocochips in that. Mix well all together.

Make small size balls of mixture. In another bowl melt chocolate in microwave for 30 seconds.

Dip the ball in melted chocolate and take out by half of fork. So that excess chocolate will drip down. Immediately sprinkle some decorative sprinkles over it. Chocolate sets very fast. Put it in fridge for a while.

Enjoy yummy, kid favorite Chocoballs.
