How long do I bake a 12 X 18 sheet cake?

post #1 of 12
Thread Starter 
I am making three 12 X 18 sheet cakes for a fundraiser this weekend. How long should I bake them for? I am planning on using the Duncan Hines cake mixes for them. I also was planning on using 3 mixes per pan (roughly), does that sound about right?

Oh, so much baking to do... I hope it goes smoothly!

Thanks in advance for any help or tips! icon_smile.gif

set the timer for 45 minutes....but plan on that being the starting time of you checking the cakes for doneness, it could take an hour or more. Really, it's hard to say without knowing your oven, how deep the batter is, what kind of pan it's sitting in. Hope it all works out for you, sounds like a lot of work ahead! icon_smile.gif

"Until it's done."

Truly, never bake by time. Bake until it's done.

a BIG THANKS!!! icon_biggrin.gif Great info!

I forgot o ask one more question... do I NEED a heating core? I don't have one, is there something I can do instead of a heating core?

I also use 3 (betty crocker) cake mixes per pan.
I never use flower nails or heating cores.
I always use baking strips.
I always reduce my oven temp.
I never use a timer. Never.
My answer to "how long?" is always "until its done". (My kids HATE it when I tell them that!)

Really? No heating cores at all? Good to know, I'm going to try it without and do as you said.

If I reduce the heat from 350 to 325, is that about right? That's what the Wilton website said for 12x18 sheet cake. How full do you fill your pan? Do you use the entire 3 mixes in one pan?

I never ever realized baking large cakes could be so tricky! icon_wink.gif Thanks for the tips!

LOL about your kids hating the 'when it's done comment'... thanks for the laugh! icon_biggrin.gif

I did it just as you said indydebi... it worked! I took about 54 minutes at 325. One sheet cake down, 2 more to go!

Phew... big sigh of relief!

THANKS AGAIN!! icon_biggrin.gif

It was about 2" high. I used the 12x18x2" pan. Hope that helps icon_smile.gif
