Pour the mixture into cake pan and set it in pan on stove.wait for 20 minutes.do not disturb steam before 20 minutes then rest it on off flame for 5 minutes.

Let cool down the cake and spread at upper layer melted chocolate.

Let it cool again.now decorate with any frosting.i used instant vanilla pudding which is i think best to use if whipped cream is not available.enjoy stay safe stay healthy and happy
