Dry roast the oats on low flame until they turn crisp. Keep aside.
In the same pan, dry roast peanuts, almonds, and cashews until aromatic.
Heat ghee in a pan, add jaggery powder, and allow it to melt slightly on low flame.
Switch off the flame and quickly add roasted oats, nuts, and raisins.
Mix well so everything gets evenly coated.
Let it cool completely before storing in an airtight container.
Serve as is or pack it as a quick snack for kids.
