Heat a kadhai on low flame and dry-roast the ragi flour for about 10 minutes, stirring continuously until the colour changes and a pleasant aroma develops. Transfer the mixture to a plate and set it aside.
In the same kadhai, add 1 tablespoon of ghee and allow it to melt. Roast the nuts until they are golden brown, then remove them and set aside.
Add the remaining ghee to the kadhai. Once melted, add the roasted ragi flour and roast again on a low flame for another 10 minutes, stirring well until aromatic.
Switch off the flame. Add cardamom powder, jaggery powder, and the roasted nuts.
Allow the mixture to cool slightly, then mix well and shape into ladoos.
