I just bought a 12x18x3 cake pan and I have a few questions...

do I need a heating core to put in the center so it bakes all the way through?

how long do I cook it for?

What temp do I cook it on?

Really don't want to have to deal with trial and error since this cake is due on Thursday so any help would be awesome!

TIA

Here's a link to Wilton's 3" deep cake pan preparation and servings chart:

I would use inverted flower nails (in place of heating cores) for any 3" deep pan. And because this is such a large pan I would use multiple flower nails as well as bake even strips.

HTH

I bake at 325 for about an hour, I have bever actually timed it. I usually know by the smell when it's done.

I have never used a heating core and so far haven't had any problems with a cake not getting done.
you can always use one anyway. HTH!

Like Jan, I would use inverted flower nails. I have never used the bake even strips. I'd bake it at 325 degrees, or maybe a little lower.

Hope it turns out just perfect!

I wish I had a convection oven! lol but no I don't

I will definitely check out the chart though I actually have it saved to my computer but didn't even think to use it for this! thank you!

JanH~No, I wish!!
I have a teeny oven. It's a wall unit from the 70's. I just measured it. Inside wall to wall is 17 inches. Long ways it's 20 inches so a 12x18 just fits. I have never timed the cake because I usually get side tracked. I should correct myself to say that I check it after about an hour.
I'm not in business yet, but a new oven will be on my list!
