Line a 9" Square Tin with baking paper. Set aside.
Add the chocolate and butter to a large microwave safe bowl and microwave for 20 seconds at a time, mixing each time until smooth. Add the Nutella and whisk until well combined. Add half of the chopped graham crackers, mini marshmallows and chopped hazelnuts. Mix until well coated.
Add the mixture to the baking tin and spread evenly using the back of a tablespoon.
Add more chopped graham crackers on top along with Ferrero Rocher’s and some mini marshmallows. Chill for 2 hours.
To prepare the gold paint add the gold lustre dust and vodka to a small mixing bowl. Mix until well combined.
Use a kitchen brush to splatter the gold paint on to the rocky road by flicking the bristles. Allow to dry for 20 minutes. Cut up into bars and serve.
