Please help!! I have been decorating cakes fro a long time, I recently perchased a 20 x20x2 inch square cake pan. I looked every where and I cant find out how many this will serve. It will be doubled of corse.
I would really appreciate some information on serving sizes
According to my math. Which is for 1.5" x 2" serving piece. A 20 x 20 square will serve 133. Hope this helps
Square cakes are really easy to figure servings, it just takes a little math.
A cake serving is 1"x2"x4" or 2"x2"x2". So if you're doing two layers for a 4" tall cake you just take one side divided by 2 for 10 slices along one side (all 2" wide) and then you multiply it times 20 since your other side will be cut every 1" for servings.
So 10x20 = 200 servings for a 20" square cake that is 4" tall.
Now if you're figuring on larger servings you'll have a smaller number of servings, but the 1"x2"x4" is industry standard for serving size.
Just curious though... are you baking in a commercial kitchen? Just checking because a 20x20 pan won't fit in most standard ovens unless you have a large commercial oven.
Yes, a 20" square serves 200 if 4" tall, however, I believe all cakes 18" and larger really should be 6" tall to look strong, sturdy, and proportionate to the tiers above that it's supporting. IMO, there's nothing more ugly than seeing a short and squatty base tier especially if the tiers above turn out to be taller than the base.
If 6" tall, it would serve 300 as long as you use a board in between at 3". (Of course, these slices would only be 3" tall instead of standard 4".)
