Take a bowl and add butter. Butter must be at room temperature.
Whisk it either using a hand whisker or electric whisk.
Whisk until butter turns soft, pale, and creamy.
Add whole wheat flour, baking soda, cardamom powder, and salt.
Mix them so well, again either with hand or electric whisk.
Lastly, add crumbled Soan Papdi.
Now mix it using your hand.
Do not knead it like a dough but just bring it together and form a dough.
Take out small balls out of it and roll them between your palms.
Arrange these balls on a baking tray lined with greased butter paper. However, we have a silicone mat on the tray.
Tuck the nuts of your choice on these balls. We have used pistachios.
Place the tray in the refrigerator for 30 minutes.
Bake in a preheated oven @160°C for 30 minutes or until the cookies begin to turn slightly brown.
Let the cookies cool down completely.
Enjoy.
