Line a 20cm square cake tin with baking paper – it's important to make sure that you leave plenty of paper hanging over the sides to help you remove the fudge once it has set.
Pour the condensed milk into a medium saucepan over low heat and add the milk chocolate – which has been broken into squares.
Stir regularly until the chocolate has melted and the ingredients have combined.
Remove the saucepan from the heat and add the Clinkers before quickly stirring through.
Pour the fudge into the prepared tin and place in the fridge for a minimum of 6 hours (preferably overnight) to set.
Remove the set fudge from the fridge and cut into squares.
