Melt ghee in a pan on medium heat. Once the ghee melts, add atta to it and mix to combine well with the ghee. 

Heat 1 cup water in a pan on another stove. You want to the water to be boiling hot when you add it to the ghee-atta mix. So keep it ready to go.

Continue to stir the atta and cook until it turns brown in color and gives a nice aroma, take around 6 to 7 minutes on medium heat.

Be careful to not burn the atta here

Add the hot water now. Be careful as you add it since the halwa will bubble like crazy

Stir continuously for a minute or two as you add the water and the water gets absorbed by the flour.

Add in the sugar and mix. The halwa consistency will become liquid-y again after adding sugar

Continue to cook for 2-3 more minutes on medium heat after adding the sugar.

Add cardamom powder and mix (optional). Stir to mix in the cardamom powder and remove pan from heat.

Serve atta halwa immediately. It tastes best when warm! You may garnish with some nuts.
