Grease and line an 18cm brownie tin with baking paper.
Place the digestive biscuits in a freezer bag and bash with a rolling pin until broken into a good sized lumps, no larger than a 50p. Set aside.
Melt the butter or margarine, the chocolate and the golden syrup in a large saucepan over a gentle heat, stirring constantly until the chocolate is only just melted, then remove from the heat and leave to cool.
Add the biscuits, mini marshmallows and hazelnuts into the chocolate mixture and gently stir until everything is completely coated.
Tip the mixture into the lined baking tin, and spread it out to the corners. Arrange the chocolate discs on the top and chill for at least 2 hours before cutting into squares. Keep stored in the fridge for up to a week.
