I'm making a half and half cake (half chocolate/half white in a 11 x 15 pan) and at the 40 minute mark, it appears my chocolate cake is going to be done before the white half of the cake....what do I do?

I have never done this before but I would suggest covering the chocolate side tightly with foil. This should help. Good luck.

Thats what I did, cover the chocolate side with foil, it seemed to help!

Thanks. That's what I was thinking too, but wasn't sure. At 40 minutes both were not done, but the chocolate cake was just about done. At 45 minutes, the chocolate cake was totally done (but no responses and didn't know what to do), but the white cake was still not done. I rotated my pan (not sure if that helped) and set the timer for another 5 minutes. Checked it when the buzzer went off and it was done. All 10 toothpicks that I stuck it with came out clean. At 45 min. the white cake seriously looked like it had another 10 or so minutes. I wonder if rotating the pan helped. Maybe one side of my oven cooks faster than the other????

could be ... my oven has a couple of 'hot spots' and I have to rotate cookie pans on a couple of the racks.

Thanks everyone. The cake looks higher on one end of the cake so I'll have to level it. Hoping its cooked tho. Off to go wrap it up tonight and chill so I can torte and fill it tomorrow.

Debi - is there a way to fix the oven or do you just live with it until you get a new one?
