Grease the pan properly from all sides.

Place parchment paper.

Tap the pan to release air bubbles.

Set the stove pan and preheat the pan before 5 minutes on high heat.

Add 150 ml water in the pan to moist and chewy cake texture.

Place any stand on the pan to avoid direct heat from the pan bottom.
