Is there such a thing as a third size sheet cake pan? More ? inside

So I’m to do the twins next door birthday cake again. They will be 8 and requested a The Incredibles theme cake. Well I’m over making fancy tiered cakes when this is going to be mostly a bunch of kids running around on a jumpy house waterslide and eating pizza. So I’m just going to do a sheet cake.

The problem is not all the RSVPs are in yet but we’re already at 35, so a quarter sheet pan is not going to do it and half sheets always seem like there is so much cake. So, is there such a thing as a third size sheet pan or somesuch?

Also, there is the problem of converting a three 8” layer cake recipe into whatever size is going to feed this amount of people?

Any and all insight would be helpful as my brain is not cooperating with this math challenge.

PS

Twins want to help make the cake this year - give me strength!

 
Hi M. Half sheet = 12x18, quarter sheet = 12x9, jelly roll = 10x15

Areas = (assuming 1" height)
Half: 216 SQ IN (~14 cups of batter >> 100 servings)
Quarter = 108 SQ IN (~7 cups of batter >> 50 servings)
Jelly Roll = 150 SQ IN (~10 cups of batter >> 75 servings)

Serving size is 1" x 2" (per Fat Daddio's cake pan data)

Jelly roll (aka Texas Sheet Cake pan) has 1" sides. It's close to a thin cookie sheet, but the sides are higher for baking batters.

Any 3-layer cake recipe can be baked in 3 9" pans. It will just be a tad thinner and cook faster. I'd go for square disposable ones because the AR part of me likes square edges for measuring. If I had been around at the turn of...math, Pi would never have been invented because I hate dividing up circles.

How much food will there be? That will help with the cake slice size: lots of food and snacks means a smaller piece of cake should satisfy. But then I've never baked for a group of hyper-bouncy kids, so what do I know.

 
I need a half sheet size then I guess...

But I’m not sure what you’re thinking, to make three square layers and then line them up/ice as one sheet cake?

I think I’m confused. Very likely I’m confused. Math confuses me.

 
Let's blame my 9 inch discussion on *circumstantial speech*

"Circumstantial speech (also referred to as circumstantiality) is the result of a so-called "non-linear thought pattern" and occurs when the focus of a conversation drifts, but often comes back to the point. In circumstantiality, apparently unnecessary details and seemingly irrelevant remarks cause a delay in getting to the point."

Who knew there was a formal term (not to mention a Wiki page) dedicated to my random babbling!

I think my brain caught a snag when you mentioned layered cakes. To be honest, I can't get back to my own reason for adding it.

Now where did I put that boning saw??

 
Note the serving size for the yield quotes for these pans is a 1" x 2" slice.

The only time I've seen servings that size is buffet-style, so smaller slices served to accomodate for people taking several different items.

I would consider allowing for a larger serving size for your event, even a 2" x 2" slice will yield half the servings stated in the reference from M.

With 35 guests, you would still be fine with a half sheet.

You are very kind and generous to do this! The twins are very lucky. smileys/smile.gif
