Line a pan with foil and set aside.

Take peanut butter, sugar and dark chocolate in a sauce pan and heat it on low heat till the chocolate is melted. Now pour this into the foil lined pan.

Now in a separate pan, take white chocolate and melt it down.

Drizzle this over the dark chocolate mix and use a chopstick or skewer to make swirls pattern.

Put this in fridge to set for couple of hours.

Cut into pieces and enjoy.
