*sighs* when I finally removed the lid to view mah masterpiece, it resembled pudding in every aspect. I just thought the lid would help prevent crackage !!! But noooooooo ! With the lid off, I turned the oven back on to 400. Immediately the top rose gloriously and looked as if it might be salvaged, unaware of the pending grand collapse. What I created was a marvelous BOWLING BALL MITT ! Without a doubt, I achieved the most perfect example of the " fallen cake " ever I've seen. Interestingly enough, the great gaping hole, never cracked !!!!!!!!!!! Final baking time ? 3 hours and 30 minutes.
You're the first person I've come across, to find a need to use the mallet to the head smiley, lol. Well implemented
