Probably cooking it too fast. Big bubbles form but if you cook it slow, it doesn't rise too fast and still bakes firm before it can get too bubbly. I'm not a pro, but that's my take.
So what's with the carrots on the cake? Is this for Rabbit-Chan? Blasphemy, I say. Also, learn what thumbnails are and why people hate links to them.
U fail, cake fails, link fails, therefore thread fails. If effort counted, you would win, but not in this god-forsaken pessimistic place.
