Cocoa Sponge Cake with Whipped Chocolate Ganache

Pin It Now!

This is a cocoa chiffon cake recipe which I baked in round pan and decorated with chocolate ganache. Sometimes I have to find a way to clear stuff in the fridge and this time is whipping cream. Despite clearing whipping cream I have fun in making decorated cake too ^^ My kids are very happy to see and enjoy eating the chocolate cake.

Instead of cover the whole cake with chocolate ganache I used homemade roselle jam as the filling. You can replace other jam of your choice.
