I'm making an anniversary cake for my grandparents and am trying to figure out how much cake I should make. There willl be 23 people. Originally I was thinking an 8" round and a 6" round would be enough but now that they're baked, I'm starting to wonder if that won't quite feed everyone. I know people will want a little larger slice than that typically served at a wedding. Since this is going to be a tiered cake, should I go ahead and make a 10" round as well? Thanks for your input!

A two layer 6 and 8 serves 36 1x2 in pieces. If you add a 10in round to it, it will then serve 74 pieces, three times the cake you need.

You could do a 6 and 10 cake, which would would be 50, still double what you need, though.

The 8" cake is 4 layers and the 6" cake is 3 layers. Is that enough for actual full slices of cake for 23 people?

If each 'tier' is over 3-4 inches tall, the size you are making should be plenty.

Or course I believe in the smaller cake sizes. I don't think it is up to us to serve every person a super sized piece of cake. To me cake is in addition to other things, it isn't something you get to eat piece after piece until you are full.

Thanks
