Line an 8" square pan
Combine the butter, golden syrup and kinder chocolate in a small saucepan. Heat on a very low heat, stirring constantly.
Once all melted, turn off the heat. Add in the Rice Krispies cereal and stir together.
Press into the pan and chill for 30 minutes.
Melt each type of chocolate separately (in small microwavable bowls, checking and stirring at 20 second intervals). Pour over the krispie treats and spread with a spoon to cover. This should create a swirly effect.
If using, sprinkle over some chopped kinder chocolate. Chill for another 30 minutes - 1 hour before slicing and serving!
