Your custom birthday cake details
Above the typical range — usually premium options or a more complex job.
A custom cake's cost is mostly the decorator's hours, not ingredients, so fondant, sculpting, tiers and hand-made figures are what push the price up. A buttercream single-tier cake is far cheaper than an elaborate fondant creation.
💰 Ways to save
- Catering is per head, so a realistic final guest number (not an optimistic one) is the biggest lever on the bill.
- Ask what is included, staff, delivery, equipment hire and GST are often extra on a per-head quote.
- Mid-week and off-peak dates are cheaper, and some caterers discount for larger numbers.
