Line a standard 8-inch (20cm) square baking pan with parchment paper, leaving some overhang for easy removal later.
Chop the Mars Bars into small pieces and combine them with the butter and golden syrup in a large heatproof bowl.
Melt the mixture over low heat, stirring constantly, or microwave in 30-second intervals, stirring after each, until smooth and fully combined.
Gently fold in the Rice Krispies until evenly coated with the melted mixture.
Press the mixture evenly into the prepared pan, using the back of a spoon or your hands to pack it down firmly.
Melt the milk chocolate and dark chocolate together in a heatproof bowl set over a pot of simmering water, or microwave in short bursts, stirring frequently.
Pour the melted chocolate over the rice mixture in the pan, smoothing it out into an even layer.
Refrigerate for 1-2 hours, or until the chocolate topping is set and firm.
Remove the slice from the pan using the parchment overhang, and cut it into 12 equal squares or bars with a sharp knife.
Store in an airtight container in the refrigerator for up to one week. Serve and enjoy!
