Chocolate Sponge Cake 巧克力古早味蛋糕

Ever since the 古早味蛋糕 came into the scene, I find that the English name for this cake is way too loosely used until the original Castella cake is over shadowed.

I have attempted 古早味蛋糕 here and a Castella cake here, my research shows that the later uses bread flour and it has a totally different texture from the 古早味蛋糕.  I rather call this a sponge cake rather than a castella cake.

Anyway, since I have attempted a cheese version, I shall add this Chocolate Sponge Cake 巧克力古早味蛋糕 version to my journal.   

Will be sharing this with a group for tonight's Mid Autumn Festival celebration.

Findings: The cake texture is light and moist.  Definitely a keeper.
