Taiwan Sponge Cake 古早味芝士蛋糕

So like everyone else i am eager to try the spongecake. But nope i didnt queue . They have similar shop at  neighbourhood area (Mahkota Cheras), which we manage to buy without queue. I think is goin at RM18 for the cheese flavour. Anyway we only bought the cheese flavour 2 times! Until family member suggest that i should try baking them. So here it goes. The picture looks decent right? It took me the 3rd attempt (hehehe).

The same recipe - 
1st attemp 6 eggs recipe bake in 10" way too shortie cake.
2nd attempt , run out of eggs so scale to 5 eggs recipe bake in 5 " round cake tin. Overflow but texture is there and slight undercooked. What to do-small tin all cramped inside, difficult to get even heat. 
Finally i use 9 eggs recipe for 10" square pan. Maybe i should double recipe for 10" square pan for even taller cake. Until next time.
