Line a baking tray with grease-proof or baking paper.
Break up the dark chocolate and place it in a microwave safe bowl.
Melt the chocolate in the microwave in 30 second bursts, stirring between each one to ensure it melts evenly. Be careful not to overheat or burn the chocolate, heat only until just melted and smooth.
Pour the melted chocolate onto the lined baking tray. Using the back of a spoon or spatula, spread the chocolate around so that it covers the tray in a thin, even layer.
Scatter the chopped dried apple evenly over the chocolate, followed by the toffee popcorn and the mini fudge cubes.
Place the tray in the fridge and chill until the chocolate is hard and completely set - around 15-20 minutes.
Once set, remove from the fridge, carefully peel from the grease-proof paper and cut or break into pieces.
