Check out my normal way of making Kalakand in Microwave. However, since I had paneer that already had the sugar mixed in, I add milk powder, condensed milk, cocoa powder and made.
In a microwave safe bowl, take paneer, milk power, cardamom powder, mix. Finally add half tin of condensed milk. Micro for 4 mins and 30 secs.
Remove and add the cocoa powder, 1 tbsp of ghee. Mix well and put it back. Micro for 1 min more.
Remove and pour over a greased pan. Sprinkle finely slivered pistas. Let it cool down completely before cutting into small pieces.
It takes about 30 -40 mins to cool down to be cut into pieces.
