Line a 20cm square baking dish with baking paper - make sure you leave paper hanging over the edge.
Place the maltesers in a single layer over the base of the lined tin.
Combine the condensed milk, chocolate and melts in a microwave safe bowl and cook in the microwave for 30 seconds spurts until melted. Stir until smooth.
Quickly pour the melted mixture over the top of the maltesers and gently smooth the top.
Place in the fridge for 2 hours or until set.
Remove from the fridge and carefully life the fudge out of the baking tin.
Cut into small pieces and enjoy!
