I've been approached about possibly doing a full sheet cake for a co-workers friends birthday. What is the standard size for a full sheet cake? I have the 11x15 and the 12x18 Wilton pans, but I'm unsure if either is the correct one.

AND

If the 12x18 is a full sheet, then how can the 11x15 be a half sheet-or is it?

Thanks ya'll!

Tina

I think everyone will have a different idea, but I consider the 12x18 a full sheet. More importantly though, I think, is how many servings you'll need!

I consider a 12x18 a HALF sheet. (some consider the 11x15 a half, and bakeries vary on which one they use) So a full size sheet, to me, is 18x24.

Sherry, you're so right, I had a brain cramp.

Thanks for the replies. Do they make an 18x24 pan or do you have to paste two cakes together? Not meaning to sound dense, but I'm still a newbie at all this.

Thanks again!

Tina

No, they don't make a pan that large, so you have to put 2 cakes together. You can make one choc. and the other white or Yellow for a half & half cake!

Since you have both pans, (the 11x15 and the 12x1 you could use either of them to make the full sheet, because both are acceptable.

yes a half sheet is 12x18 and a full sheet (two half sheets place long sides together) makes an 18x24 cake. Enough to feed roughly 90-96 peeps if you cut it into 2x2 inch squares (if not layered)
consequently, a quarter sheet is a half sheet cut in half.

You guys are the best! Thanks so much!

Oops, one more thing though.... How do I transport them? They don't make the boards from Michaels that size.

Tina

You'll need to cut a piece of plywood for that one. Measure the full sheet box to get your size. Cardboard won't be good enough, a cake that size is unwieldly!

I go to my Local Kroger and buy a full size sheet cake box. They know me now, so When they see me, they just go grab one.

Make sure you buy extra boards though, and tape them together. I buy foamcore board (thick) and cover it, because a full sheet cake is very heavy, and your icing will crack when you try to lift it if it isn't on a very secure board.

that's right full sheets are very very heavy and even more so when filled. the plywood thing would work great and you can always use it again and again. Be sure to cover it with contact paper or some kind of grease proof covering like foil

Can I get foamcore at Michael's or AC Moore? I don't plan on filling a sheet cake, that would be too dang difficult I think.

Thanks again ya'll! I'll see if I can find that stuff this weekend.

I use plywood for full sheet cakes...
DOn't want it to end up cracking when picking it up...
