I am doing a pirate ship cake for my son in a couple of weeks. Some of the tips I've recieved from this site suggest starting with a loaf pan and carving from there. Anyway I was going to do a practice one this weekend and the cake would not get done. It was in the oven for about
1 1/2 hrs and it was plump and spongy when I took it out, but with in 10 minutes it sank and when I cut it, it was completely unbaked in the middle. Yuck. Good thing this was only a practice cake. Also does a glass pan make a difference than a metal one. I used glass because it was the only one I had. HELP. 
Baking in a glass pan browns the edges too soon. If glass all you have, wrap the outside in aluminum foil, and set it on top of a baking sheet. That should help keep the edges from browning before the center is baked.
i've had the same problem with my cake. it was because the pan was filled with too much batter so the center didn't cook properly. do as nadya suggested, with the flower nail or heating core. just spray the flower nail or heating core and place it in the pan. and i've recieved advice about baking at 325 until a tooth pick comes out clean.
