Melt the dark chocolate and butter together in the microwave in short bursts on medium.
In a large bowl, mix the cornflakes and coconut together.
Pour the melted chocolate mixture over the cornflakes and coconut, and stir until each piece of cereal is coated.
Transfer the mixture into mini baking cases arranged on a tray - I use about a heaped teaspoon of mixture per case.
Put the tray in the fridge to set whilst you make the cheat's salted caramel.
Melt around 15 Werther's Caramel Chews (or similar caramel lolly) over a low heat. Add in sea salt and stir.
Drizzle caramel over each Chocolate Joy. Tada!
