Chocolate Sponge Cake is also known as Chocolate biskvit. It is very similar to traditional white biskvit except you add cocoa powder and less flour to make a perfect chocolate sponge cake layers that can serve as a base for many different chocolate cake
I am a big fan of cooking shows, especially those on baking. I found this recipe a few months ago from Cake Boss & now it's all I use for my sponge cakes. The secret to this cake being Light & Fluffy is the beating of the eggs. Don't rush that step.
