Portion Guide

When designing your cake one of our first questions will be “how many guests are you catering for?” and “are you serving your cake for dessert?” These questions will help us to determine how large your cake will need to be. This serving chart should be used as a guide only to give you a basic idea of the size of cake you will need. Please also be aware that some designs of cakes can only be made in one size.
