Dual Flavour Golden Sponge Cake 双色黄金蛋糕

I have bookmarked this recipe for a long time as I have not experiment with cooked dough method aka tang mian 烫面.  Since I need to do my weekly Thurs bake for my mom, this will be a good time to try out this recipe.

To entice my kids to eat, I have turned this into a Dual Coloured Golden Sponge Cake 双色黄金蛋糕 so that my son will know that there is "chocolate" in it.

Finding: The texture is soft soft and moist.  Totally love the texture.  I shall explore more on this recipe.  

Unfortunately the top of the cake cracked halfway through baking despite the low temperature.  Now I wonder why can't I get that smooth sexy top.

Nevertheless, this recipe is definitely a keeper!
