Transfer the mixture to your lined dish and push down with the back of a spoon until tightly packed.

Melt the butter sugar and condensed milk in a saucepan allow to boil for 5 minutes stirring all of the time so it doesn’t burn. This will melt the sugar and create caramel that will harden when cooled.

Melt the milk chocolate once the caramel has hardened.

Pour over the top and return to the fridge

Melt the white chocolate and sprinkle on top, return to the fridge to harden
