I am making a 40th birthday party cake for about 70 people for next weekend. My original thought was that I would do a double layer 11X15 which would feed just enough people if the slices were small. They are having the party catered by a barbeque place so there will be lots of other food.

What would you do? If I make it a 12X18 I won't have enough with a single layer and a double layer will be wayyy to much. But I don't want the cake to appear too small to feed everyone either (I know this is probably not that important but it was something I thought of too)

I really appreciate your help. I am so glad CC is up today and I hope it stays up, I have a lot of research to do today

Personally, I'd go with the 12x18, but I'm also the queen of making too much Have something folks can pack up leftovers to take home.

Alternatively...since there's going to be bbq and it seems to be a more casual 'do, how about cupcakes?

Or.............do the 11x15 cake and some cupcakes for extra, especially if there will be some kids there.
