Im making a children's birthday cake for a 3 year olds party on Saturday (last minute as always) and i need to make the cake serve 50 people!! The age range is going to be from under 1 to 8 so the portion sizes are going to vary and im planning on making a 2 tier round cake, its my first big party cake so im just so unsure! What would other people do for a party of this size?

I personally would do an 8 and 10 inch to feed 48people and talk it over with the customer to see if they agree because of the ages.

A 10" and 6" serves exactly 50:

The customer may want a smaller cake with fewer servings if many are toddlers.

Thank you! Think im going to go for a 10 and 6 inch
