Mix together Milk Powder, Powdered Sugar, Dessicated Coconut and cardamom powder in a bowl.
Add cold milk one tablespoon at a time mixing with a Spatula till it comes together as a dough. Do not add too much milk to prevent a sticky mess. Once it comes together, grease your palm with ghee and knead into a dough. Do not knead too hard just until combined.
Add Ghee and form a smooth dough. Cover Rest for 5 Mins.
After 5mins, the dough will be easy to shape. Place the dough in a parchment paper greased with ghee and shape till a Log forms. Once shaped, wrap it up in the paper and store refrigerated for 15 Mins.
Once firm, place edible Silver vark optionally on the Log and cut into your desired thickness.
Place few chopped pistas and almonds at the center. Use a knife to press them onto the Barfis. Quick Diwali Barfis are ready to be served. Store them refrigerated.
