I am trying to figure how many 2x2x4 servings I'm going to get out of a 13x18 cake...

I do not own a 13x18 pan (or anything that remotely big) but am going to make two 9x13s and lay them side by side, double layer. I know this sounds like a lot of cake but also I need some wiggle room because it will be a carved piece.

Thanks.

Here's a couple of charts you could have a look at, hope it helps.

Just so you know, the 2"x2" "party" serving measurement is meant for single-layer, 2" high cakes, not 2-layer 4" high cakes. The standard serving size for a 2-layer 4" high cake is 1"x2"x4.


2"x2"x2" piece of cake is 8 cubic inches of cake

1"x2"x4" piece of cake is 8 cubic inches of cake

2"x2"x4" piece of cake is 16 cubic inches of cake (almost a foot and a half of cake per person!)


A 9"x13"x4" cake (468 cubic inches of cake divided by 8 cubic inches of serving) gives 58 1"x2"x4" servings, so two of them will give 116 1"x2"x4" servings.

A 9"x13"x2" cake (234 cubic inches of cake divided by 8 cubic inches of serving) gives 29 2"x2"x2" servings, so two of them will give 58 2"x2"x2" servings.

If you really want to go with the double sized servings, a 9"x13"x4" cake (468 cubic inches of cake divided by 16 cubic inches of serving) will give 29 2"x2"x4" servings, so two of them will give 58 2"x2"x4" servings.

Thanks Pterell. I have to admit that most of that math confused me LOL but it will be a carved piece so the finished product won't be 4" tall, probably 2-3.
