Need Help With 9X13 Serving Yield...

If I make a 2-layer 9X13 sheet cake, how many servings will that yield? I need to make a sheet cake for a baby shower next weekend, and it needs to feed 20 people. I just want to make sure before I go out and buy a bigger pan. Thanks for your help!


according to the Wilton guide a 2 layer 9 x 13 will serve 45 - 50.



We get 20 servings out of a 9x13, 1-layer. If you do a 2-layer, they say that the pieces are cut smaller since it's twice as high, so you could probably get 35-40. It just all depends what chart you are looking at. I would say that a 9x13 will be plenty for your gathering.

It will be more than enough, I just had a party with a 2 layer 9x13 and it was more than plenty big for a crowd of 20.

For sheet cakes it is easy to figure servings: divide the long side by 2, then multiply by the short measurement. So a dbl layer 9x13 will yield 6 (1/2 of 13 ) x8 or 48 servings.
Another way to figure it is each cake mix used yields 12-15 servings. A 9x13 pan needs 1 1/2 mixes so you can get 18-30 servings from it, depending on how big you cut the pieces.
Remember also, all cakes shrink some after baking so a 9x13 pan will give you a cake that is approx. 8x12 before icing.
For selling/pricing guides almost all of us follow the average of a serving being 2"x2"x2" (silgle layer) OR 1"x2"x4" dbl layer. Even if a round cake you still use these figures - treating *all* shapes as if it was a sq for cutting. The smallest end pieces are dbld up for one serving or discarded in the count.

I made a 9x13 two layer (not torted, two full layers) and used a piece of waxed paper to figure out servings. I folded it and folded it in equal amounts and found that 32 was a good number. These would be good party servings and I'm sure you could get more out of that cake, but that was a good starting point for servings. I couldn't imagine cutting that into 20 servings. That would be a lot of cake per serving!

Thanks to all for your help. Kakeladi, if I were to charge for this cake, what would you say the price should be. I know some prices here are $30 for a 9x13 sheet cake with just BC (and I believe that's one layer). If I added some fondant figures, how much should the price go up? TFYH
