Dry Roast all nuts on low flame for 10-15 seconds or until warm.

You can also use the microwave to roast the nuts, which I did.

Nuts need to turn just warm and crisp, not hot.

Cool, powder. I went a little ahead and got a slightly wet mixture (which is 2 steps short of nut butter)

While still warm, add the powdered sugar, milk powder , cardamom powder, vanilla and milk (if using) and sightly knead to a soft dough.

Pat on a greased plate / parchment paper.

Refrigerate for 15 - 20 mins and then cut into barfis.

If you don't add milk, this will keep for 4-5 days on the counter itself (weather permitting). But I prefer to refrigerate it.

Store in an airtight container in the fridge and consume within few days
