How to make Cocoa Sponge Cake
To prepare your very own Cocoa Sponge Cake recipe, take a bowl and add the readymade chocolate cake mix along with water and egg. Take a hand mixer and whisk everything nicely for about 8 minutes. Make sure the batter is light and airy.
Put this batter in a cake mould or a baking tray. Put the cake mould or baking tray in the oven. Bake for around 25 mins or more in case the cake has not baked properly. Your Cocoa Sponge Cake is ready to be served.
