I am hoping that Zukerig will get back to me on this as I know that this post is old. I baked your cake today....what I tasted I would say it is very good. BUT I had a problem, the center sunk. I used a different pan however. I used a 3" pan with parchment  around the edge making it about a 4 1/2" pan. I used the entire batter but failed to turn the oven down. Do you suppose that is why it flopped as I had this problem the day before with another vanilla recipe...(YES...
