Give a realistic range instead of a single guess
If you currently expect between 35 and 45 people, say exactly that. A range is more useful than pretending the number is already fixed. It tells the baker how much uncertainty exists and helps prevent the cake decision from being built around a number that may change the next day.
Also explain who the guests are. A children's party, office tea break and evening family celebration may use cake differently even when the headcount is similar. Moh Bakes confirms the final size from the actual order details rather than publishing a fixed serving chart that may not fit every cake or event.
Explain the rest of the menu and serving plan
Tell the baker whether there will be cupcakes, ice cream, fruit, a dessert table or a full meal before cake. If cake is one of several desserts, the way it is served can be different from an event where the cake is the main sweet item. This context matters more than copying a serving estimate from another event.
If the cake will be cut by catering staff, mention that too. Smaller controlled portions and informal family cutting can produce different outcomes, so the service method should be part of the conversation.
Set a decision point for the final number
Choose a date when you expect the guest list to become clearer and share the event date from the beginning. That allows Moh Bakes to discuss what can still be adjusted and what needs to be confirmed earlier because of decoration, structure or scheduling.
If the number remains uncertain, decide whether your priority is avoiding shortage or avoiding excess. That preference helps the baker understand the practical risk you care about most.
