Measure and keep all ingredients ready. Dry roast the sesame seeds in a pan until they crack and nice aroma comes. Switch off the flame once the sesame seeds turn brown.
Grind the roasted sesame seeds to a slightly coarse powder for 5 to 10 seconds. Then add powdered jaggery, peanuts(if using) and cardamom to the blender.Grind again for a few seconds until the sesame seeds, peanut and jaggery are well blended.
Transfer everything to a plate or bowl, add broken cashews and mix well. Break any lumps formed with your fingers. You can skip the ghee if the oils released from sesame seeds & peanuts are enough to roll them into balls.
Roll the mixture into laddus till all the mixture is used up. Store them in an air tight container once done. The laddus last well for a week at room temperature.
