Can anyone help with some ideas/suggestions please? I've been asked to do a number 1 cake for a little girl but they want it to feed 50 people. The usual cake frames only do about 20 servings I think. I'd gone down the road of perhaps a number 1 on top of another cake but they didn't seem that keen. Maybe cut a number with a template but can anyone tell me what size I would need to feed this many please?

thank you all

Here is a number chart http://cakecentral.com/gallery/1111573

I would use a 14" square if using the Wilton Party serving guide or a 12" square if using the Wilton Wedding serving guide. Then cut it according to the guide. HTH
