Hello!! I have a topsy-turvy cake being picked up tomorrow to serve approximately 30-40 people. The cake is 2 tiers.... the bottom is 10-9-8" and top is 8-7-6". The cake layers are tall (about 4-5" each tier) but doesn't look "big" enough. Should this be enough?? Maybe I am just hungry myself and 'secretly' wanting a piece cake, making me think this wouldn't be enough for everyone. Just wanting to advise before I quickly bake a small 8" to cover!!! Thanks!

Does this sound like enough? Maybe, yes, no.....

I by Earlene's serving size guide:

  
Pan Sizes servings
5 inch      6   
6 inch      8   
7 inch      10   
8 inch      15   
9 inch      22   
10 inch     30         

A 8 inch and 6 serve: 23 (Smallest size of layers)
a 10 and 8 serve: 45 (Largest size of layers)

I averaged them and got 34 servings, but I don't think they will cut it correctly to get those servings.

Personally, I think you're cutting it close.. maybe you can bake a few cupcakes. They will most likely assume they are getting something 'extra'.

Thanks.... I have an 8" in my frig just screaming for icing!! I would rather send than be sorry some were without cake. That's no fun at a party!!
Thanks again for your help!
