Place the thick bottom kadhai on the gas and roast the mawa in the kadhai.
Roast till the mawa releases ghee and leaves sides of the pan.
Now, keep aside the roasted mawa and in the same pan add 2 tbsp ghee.
When ghee melts, add the chopped dry fruits and roast till it turns a little brown in colour.
Now, remove the dry fruits and keep it aside. And add the grated lauki in the kadhai and stir it nicely with the ghee.
Keep stirring the lauki until it leaves all the moisture.
Now, add the full-fat milk (pre-boiled) in the kadhai and mix it nicely with the lauki. Adding boiled milk helps in preventing milk splitting.
Cook till the milk boils and make sure to stir in between, to avoid milk spill from the pan.
Once the milk thickens, add sugar into the pan and give it a nice mix.
When sugar melts, there is again a lot of moisture in the pan. Cook the lauki till it thickens and leaves all the moisture.
Now, add the remaining ghee and fried dry fruits in the pan and stir it nicely for a minute or two.
Lastly, add the roasted and crumbled mawa into the pan and mix it nicely with the lauki until it is combined well with the lauki mixture.
Finally, turn off the flame and add the cardamom powder to the mixture and give it a nice mix.
Lauki ka halwa is all ready to be served hot with chopped dry fruits garnishing.
