i'm confused on how to do a cake that serves 300 i need help.... do i make it 2 layers.... can i get a pan bigger than 12x18.... this is a first for me HELP!!!!!

You can put as many sheet cakes as you need together side by side on a large board and ice them as one cake. You may have to have someone cut you a large piece of plywood to support the weight.

Does it have to be a rectangle?

I once did a 16X16X8 and it served 256.

Does it have to be all one cake, or can you do them separately?

A double-layer 12X18 serves close to 100, so maybe you could do three of them??

remember to make sure whatever board its on fits through all the doors you will need to get through!
and consider a tiered cake instead?

Does it need to be a sheet cake???

I have a football cake in my photos, it was a sheet cake that served 300. I used the half sheet Wilton pan and it took 6 of them. I also had to contend with doorways and how to get it delivered in our van. Hope this helps.

Is it something that actually needs to be displayed or just trying to reach 300 servings. In other words- You could do 1 large impressive presentation cake but much smaller kitchen cakes to reach the remaining servings which would hopefully cut down on issues with getting a board enough but not too big to fit in doors, cars, etc

my oven won't hold larger than a 12x18 pan and bake it well. I would bake a total of 6 two inch tall cakes that ar 12x18 (one 12x18 that is 2" high serves 54, so making it 4" tall serves 10 Then i would either make 3 half sheets (12x18 that are 4" tall) or of i needed it all in one then i would push them together and decorate as one cake.
