Start by removing the whistle and rubber from the cooker. Set it on low-medium heat and spread a layer of salt at the bottom of the cooker. Place a small stand in the center and close the lid of the cooker. Let it preheat for about 10 mins.
In a bowl, add butter and sugar and whisk it well till light and fluffy.
Add the flour, cocoa powder and milk to the butter mixture and mix well to form a smooth cookie batter.
Transfer the cookie batter in a piping bag attached with open star nozzle.
Pipe the cookies on a plate greased and lined with parchment paper in an āSā- shaped pattern.
Place the plate in the preheated cooker and cook it for 15 mins.
Once the cookies have cooled to room temperature, dip half of each cookie in the melted chocolate.
