I just baked my first square cake... I let it cool on the rack, and when I came back in the kitchen it had split down the middle. I thought I could deal with it, maybe it would be okay?
Then not even five minutes later, a half of a half had split again! I used the same stuff I always do, besides the pan. Whats going on? I still need to bake another layer.... maybe I shouldnt do square pans!!?
Its really stressing me out. My cake is falling apart!!!

Did you turn your cake out onto the cooling rack with the "hump" up or down?

If it was hump down, this would explain the cracking.

(To prevent it from happening again, just flip cake layer using another cooling rack for support - so that it's hump side up.

HTH

HA, it's never occurred to me to flip the cake over on the flat side. That sure would make alot more sense to me. That probably is what the cracking happened, it's just never happened before..
I think I can repair it, I was thinking of just putting it on the bottom of the cake.... is that a bad idea??

I agree with JanH, my cake last week crack because I did not flip it over in time. Now i level them before I take them out of the pan. I always have humps, I use bake strips, heating cores, and lower cooking temps. I think my oven is just crappy.
