Will a 16 in. square cake serve 50 ppl? It is not for a wedding so I need to know if it's enough for a graduation party.

Using the standard 8 cubic inches of cake per person, a 16" square will serve 128. Even using the 12 cubic inches of cake per person that is the "Wilton Party Serving" it will serve 80.

You're serving Jethro Bodine's family?

Here is the chart that is the norm for most bakeries to figure servings, print it out and save it, that way you always have it to refer to!
