Process biscuits in food processor and transfer to a large bowl.
Add condensed milk and combine.
Take a tablespoon of mix and add a piece of snickers and wrap mixture around it.
Roll each ball in nuts and place on biscuit tray lined with baking paper.
Place chocolate in ziploc bag and place in a cup. Fill with boiling water and let sit until chocolate melts. Cut off a corner (just a small snip) and drizzle chocolate over the balls.
Place in fridge until firm. You can store in the fridge for a week or freeze for a few months.
