I really like besan and Rava ladoo more than regular big boondi ladoo. I do like the motichur ladoos though :). This is a simple recipe I use to make these at home.
Besan/ Chickpea Flour - 1 cup
Ghee - 1/4 cup
Powdered Sugar - 3/4 to 1 cup
Cardamom - 3 to 4
You can make powdered sugar in the coffee mill / blender at home. Add the cardamom after removing the shell and powder along with the sugar until the sugar is fine.
Dry roast besan in a saute pan for five minutes. Add the ghee to the power and saute until the ghee melts and the besan starts to brown. This will get rid of the raw taste of besan. Remove from heat and cool until it is comfortable to handle the mix add the powdered sugar and combine well. Then take small fistfuls of the mix and shape in balls to the size of your like.
I like these plain, but if you want you can add slivered pistachios, or raisins or fried cashews to garnish or add to the mixture before you roll the mix into balls.
The ladoos will harden once it cools.
