Just search for 'no bake' in the searxh bar u will find plenty of great options :)
This is my favourite no bake recipe by @Evani Singh
You can make any cake in a cooker or kadahi.. remove the rubber gasket and whistle of the cooker or use a lid for kadahi.. put salt on the base of the cooker and just preheat the cooker for 15 mins on high flame. Then put a stand on the salt base and put ur cake tin on the stand in the cooker.. cover the cooker with the lid without whistle and rubber gasket. Bake on high flame for 10 mins and switch the flame to low and bake for another 25-30 mins till done.
