Dry roast the oats till crispy, powder it when it cools down. Roast the ragi flour for a couple of minutes. Remove and allow to cool.
Chop the dates into tiny pieces and take it in a mixer along with the oats and ragi flour. Pulse it a couple of times and then continue till the mixer combines together.
Transfer to a bowl. Heat a kadai with ghee and roast the cashews and add the oats mix and combine well. When the heat is bearable, knead well and make into small balls of 1 inch balls.
