Spongy Cake

I was bloghopping as usual yesterday, and found this wonderful recipe at elisa's place.
It looks so yummy and yet simple enough for me to bake. It's my first cake after almost 3 months of morning sickness.
Anyway, my parents came to visit yesterday, so I baked this for them. I didn't put any topping, since they love their cakes plain. But I'm sure it taste great with whipped cream. n some fruits...
and yes..it's so soft, n spongy...chiffon-like.

I just copy paste the recipe--
