Preheat the big pan on the stovetop on high heat.(Watch the video tutorial for quick understanding). Place any stand to maintain the height from the bottom. Add water in pan and make it steamy before placing the cookie pan in the middle of the pan over the stand.
Place the cookies pan over the stand and securely cover the pan.
Bake the cookies for 20 minutes. Initially keep the temperature high for 5 minutes. After 5 minutes, the cookies will start to rise. Open the pan and place the chocolate chip cookies at the center of the cookies.
Cover again and turn the temperature (heat) to medium for 10 minutes. Last 5 minutes to keep on low.
After 20 minutes, check with a knife. Prick the cookies with a knife and if it comes out dry then take it out and cool it down.
Remove cookies from the mold and detach them with your hands.
Chocolate cookies are ready! Serve cookies with hot coffee or tea.
