Ok.. I have confused myself! I have a wedding cake due in 3 weeks that I quoted back in January. Keep in mind that when quoting this cake I referred to the 'Wilton Wedding Cake Guide' - 60 serves required for 'tea & coffee' not dessert - square cake with 3 tiers (one centre tier dummy + fruit cake top tier for anniversary). I offered to start at a 12" for the base thinking it would feed 72 as suggested in the Wilton guide.. however, I then stumbled across Earlene's serving guide which suggests a 12" square only feeds 60! That means the bride and groom would be 5 serves short! I was thinking of ditching the dummy and making a second tier in a different flavour at my own expense just incase the 12" isn't enough. I could just say I had an order cancelled at the last minute and I don't like to freeze my fresh cakes and didn't wish for it to go to waste?!
Is my first quote correct? Or do I need to ditch the dummy for real cake?

Stick with the Wilton wedding cake guide. It is the industry standard chart for adequate 8 cu. in. servings. If you use any chart other than Wilton, you're giving away extra cake for free.

Hi,

dessert serves in Australia are 1x2 inch, coffee serves are 1x1 inch, that is the standard here.
