i have never really did sheet cakes before and was wondering what size sheet cake i should use to feed 50 people. its for a baby shower

a 12"x18"x2" cake will serve 54 2x2x2 servings, perfect for a party.

I say 12x18x3. 2x2x2 is the same volume as a 1x2x4 wedding slice, which is less than most ppl are accustomed to at parties. That is not to say it is not an adequate amount of cake . I use a 2x2x3" serving as a party slice.

Can I jump in for a mintue?? I'm confused.. If you say that the cake pan 12x18 serves 50 people, then I have the Wilton 12x18 pan at home and it saids that it serves 108 people.. What am I missing??
Also, I call the 12x18 a sheet pan and the 11x15 a 1/2 pan.. Am I wrong?

A double layer 12x18 serves 108.....a single layer will serve 54. I would just make 1 layer of the 12x18 if I were you. Everyone thinks differently about this but I call a 9x13 a quarter sheet, an 11x15 a third sheet and a 12x18 a half sheet.

I would go with the 12x18 ( single)it will serve 50 people nicely!Thats what I use for that many people.

jen. thanks so much for the info.. what size is a full sheet cake?
thank you

If you bake 2 12x18's and set them side by side, you would have a whole sheet cake. They do make full sheet cake pans but most people can't fit them in their home ovens. Usually the 12x18 is the biggest sheet cake pan you can fit in your oven at home.

thank you so much.. I also sent you a email , jen...

I don't have a 12x18 pan so could i use 2 9x13 pans (since she want 1/2 chocolate and 1/2 white cake? and are thse servings based on a 2" or 3" cake? because my pans are 2". Also to save a bit of money (this is for a friend and I'm doing it for a very low price) I am just enhancing box mix. How many box mixes should i use for one 9x13x2 pan? and if this wont be enough servings i guess i could use 2 11x15 pans? or would that just be tooooo much cake????

.....but if you ask me, you can never have enough cake!!!!

You will need the 2, 11x15 pans to have enough servings. you will need 2 box mixes per pan ( I dont enhance so I cant answer that ) this is for 2in high pans . Using the 11x 15 pans you might have a few extra servings but better a few extra then not enough.
