This question comes from Carrie in response to this post about the Nordicware castle cake pan. She asks:
How did you get the cake out of the mold without it breaking up? I've got a similar mold, and I've tried 3 different cakes, but none have come out of the mold in one piece! Any advice would be greatly appreciated.
I was totally nervous too - this was the most fussy cake pan I'd ever used. But one simple thing did the trick: Baker's Joy. This nonstick spray has flour added to it to give an extra-clean, smooth release. Usually I just grease and flour my pans myself, but all the edges and crevices on this one would have made it really hard to do it evenly, without goopy lumps, and I'm sure I would have missed a spot. Baker's Joy goes beyond regular nonstick sprays with that flour coating, and it really works amazingly well.
Also, I make sure that I let the cake rest for exactly ten minutes before trying to remove it; Nordicware insists on this in their instructions. Ten minutes - no more, no less.
Anyone else have some good pan release tips?

I use Baker's Joy on my pans too. It kind of scares me because I'm sure it is full of awful chemicals, but it works really well.
i have the baker's joy but i'm not a fan. i think it tastes & smells funny. i'd rather take the time to use clarified melted butter & then flour or ground nuts
I have the same castle pan but I won't use cooking spray on it, it never comes clean. I use Crisco and flour, or cocoa powder if I'm making a chocolate cake. It's worked every time so far!
My dad has concocted something he calls "Baker's Goop" to use when he makes rolls. It's a liquidy mixture of flour, oil, and Crisco, so it's kind of like a more natural version of Baker's Joy, although it isn't a spray. He keeps it in a jar in the freezer, alongside a dedicated basting brush in a ziplock baggie. I'm not sure exactly what the formula is, but I can find out if anyone is interested.
As I live in London (see above), and have no access to Baker's Joy, I just used loads and loads of Flora (shortening) and flour. My son and I put it everywhere, but obviously I couldn't get it in every little crevice. However, given how much we used, I'm assuming some of it melted to cover the rest. I also religiously followed the 10 minutes "No more, no less" rest time instructions from Nordicware, which also probably helped. This cake is great though. When I decanted yesterday, the boys watching actually applauded! What more can you ask for?
