Can someone please tell me how I could possibly make a sheet cake that would feed 150 people. Any help would be really appreciated. Thank you!

I forgot to mention that I don't have a full sheet pan, but I have a 12X18, 9X13 sheet, 16X16, 12X12, 10X10.


A full sheet is typically 96 servings for a single layer 2x2 cake. So if you did a double layer and cut them 2x1, you would get 192 servings.

May people danter around the terms of 1/4 or 1/2 or full sheet but the *size* of the pan is what is important as each person considers each of those terms in different sizes :(
Some peo;le think a 1/4 sheet is 9x12; but it really is 8x12. Some think a 1/2 sheet is 9x12, others 16 or 18 x12. It really is 12x18.
So when BrandisBaked said a full sheet which *size* is she referring to?
There are many OLD posts about what size is a 1/4, 1/2 and full size cake is you want to take the time and effort to look them up and read all the wonderful information involved in 'sizing' cakes.

18" x 26" - standard "full sheet" size in the industry.

Thanks for the reply ladies. Unfortunately I don't have a full sheet pan (18" x 26"). I was hoping I could improvise with the pans I already have.

If you are looking for a 2" by 2" sheet cake serving, just combine cakes/pans you have to create a size that works with your design and serving needs.
9x13 is 24 servings, 12x18 is 54, 16x16 is 64, 12x12 is 36, 10x10 is 25.
If you baked four 12x12 cakes and placed them in two rows of two, you would get a cake that is 24 by 24 and 144 servings.
You can bake three 12x18 and line them in row, side by side and have a cake that is 36x18, and 162 servings.
You can take six 9x13, do two rows with 3 cakes in each row and have 144 servings.
And of course, you can easily have multiple flavors in one "sheet" as they are really just multiple cakes set up side by side and iced together.

Oh, and you can also torte/layer it to get a taller cake and cut smaller pieces. So a sheet cake (unfilled, single layer) 2x2 with a two inch high single layer, can be a filled/stacked 4 inch high layer, that is served in 1x2 slices.
So you can make four 12x12 cakes, stack them to 4' high and have a two layer cake that is 12x24, and serves 144.

OOhhhhhh my I just saw how many typos my post had UUUGGGGG :( So sorry but I guess some will understand I meant to say "Many people banter......."
One word of causion...in light of what johnson6ofus said about how to lay out the different sizes .....be sure you use a very strong board and check what size the doors/openings are so the board is not too big to go thru!
