How to Order a Cake Online in Sydney: A Simple Step-by-Step Guide

Ordering a cake online should be quick, clear, and free of nasty surprises at pick-up. Yet plenty of Sydney bakeries make it a guessing game — vague sizing, hidden notice periods, and no easy way to ask about dietary needs. Num Num's Bakery keeps it simple: pick a flavour, send a message, and collect a fresh, 100% eggless cake from one of two Sydney shops. This guide walks through every step.

It also matters who can eat the cake. With 38.6% of Greater Sydney born overseas and 42.0% speaking a language other than English at home, per the 2021 ABS Census, an inclusive cake is rarely optional. Because every Num Num's cake is eggless by default, ordering online here means one cake that suits the widest possible guest list.

How Do You Order a Cake Online in Sydney?

To order a cake online in Sydney with Num Num's, you do three things: choose a flavour and size, send the details by WhatsApp or through our order page, and collect on your chosen day. From our order data, the whole process takes most customers under five minutes, and we confirm price, size and pick-up time in writing before anything is baked.

That confirmation step is the part people value most. There's no ambiguity about what you'll get or when — you'll have it in your chat history. Below is the exact sequence, then the detail on sizes, notice, custom designs, and pick-up so you can get it right the first time.

1. Browse flavours: Open the Our Cakes page and shortlist one or two of the 15 eggless flavours.
2. Send your order: Message +61 425 697 725 on WhatsApp, or use the Order Online page, with flavour, size, design, pick-up date and any allergy needs.
3. Confirm in writing: We'll reply with price, size and collection time. Approve it and your cake is locked in.
4. Collect fresh: Pick up from Harris Park or Riverstone on your chosen day — see the Locations page for addresses and maps.

Why Order Your Cake from Num Num's?

The reason to order from Num Num's is one decision that solves several problems: every cake is 100% eggless, so it fits egg-allergic guests, Hindu vegetarian and Jain family members, and anyone who avoids eggs — all in a single order. In 2025, the National Allergy Centre of Excellence reported 8.2 million Australians (30%) now live with allergic disease, so an inclusive cake is more useful than ever.

In 2025, the National Allergy Centre of Excellence found 30% of Australians — 8.2 million people — live with allergic disease, double the 19.6% recorded in 2007 (NACE, Costly Reactions report, 2025). Ordering a fully eggless cake online removes the guesswork of catering for a mixed Sydney guest list.

From our order data, customers come back for the combination of range and reassurance. Fifteen flavours mean nobody's stuck with one token "safe" cake, and a fully egg-free kitchen means the dietary question is already answered. We hear it most from parents organising kids' parties with one egg-allergic guest — the relief of ordering once, for everyone, is real.

It's also genuinely Sydney's easy option for inclusive ordering. To compare the wider market, our guides to the best cake in Sydney and cakes near you in Sydney put Num Num's in context.

What Information Do You Need to Order a Cake Online?

To order a cake online smoothly, have five details ready before you message: flavour, size or guest count, the pick-up date, any design or message, and any allergy needs. From our order data, having these to hand is what turns a five-minute order into a one-message order — and it avoids the back-and-forth that delays confirmation.

Your quick online-order checklist

• Flavour: one or two choices from the 15 eggless flavours.
• Size or guest count: tell us numbers and we'll suggest the right size.
• Pick-up date and time: and which shop suits you best.
• Design or message: a name, age, theme, colours, or a reference photo.
• Allergy needs: we're egg-free, but flag dairy, nut or other concerns.

Not sure on size? The Order Online page has a sizing guide, and the next section breaks down servings by size so you can order confidently.

What Cake Sizes Can You Order, and How Many Do They Serve?

As a guide, an 8-inch round serves around 20, a 10-inch around 35, a 12-inch around 50, and a two-tier cake 70 or more. From our internal ordering experience, most family birthdays land on an 8 or 10-inch, while larger gatherings and events do best with a 12-inch or multiple cakes in different flavours. Slice size shifts the count, so round up for a hungry crowd.

How Far in Advance Should You Order a Cake Online?

Order at least 48 hours ahead for a standard cake, and 4–5 days for anything custom or large. From our order history, the single most common reason an order can't be filled is simply too little notice — every cake is made fresh, not pulled from a fridge, so the lead time is real. Booking earlier also locks in your preferred flavour and pick-up slot.

From our order data, demand spikes hard around Diwali, Eid, Christmas, Mother's Day and the NSW school holidays — and those are exactly the windows that sell out first. If your event falls near a festival, we'd suggest ordering about a week ahead. For everyday birthdays, two to three days is usually plenty, with Thursday a smart day to beat the Friday rush.

Need a custom design under time pressure? Message us anyway — we'll tell you honestly what's possible for your date rather than overpromise. For more detail on custom timelines, see our guide to ordering a custom eggless cake online.

Can You Order a Custom-Designed Cake Online?

Yes — you can order a fully custom cake online by sending a reference photo, theme, colours or message with your order. From our experience, the clearest briefs get the best results: a photo of a design you like, the name or age to write, and your colour preferences are usually all we need to quote and confirm. Every custom cake is still 100% eggless.

Custom and photo-print cakes take more time than standard ones, so allow 4–5 days where you can, and longer around festivals. Popular requests include kids' character cakes, number cakes for milestone birthdays, and elegant single or two-tier designs for engagements and anniversaries. Whatever the look, the cake underneath is the same egg-free recipe.

Where Do You Collect an Online Cake Order in Sydney?

You collect your online order from whichever Num Num's shop suits you — Harris Park near the Parramatta CBD, or Riverstone in the north-west. Both are 100% eggless kitchens, so the cake is identical wherever you pick it up; the only question is which is closer to you on the day. We're currently pick-up only, which keeps every cake at its freshest.

See both on the Locations page, with maps. Tell us your preferred shop when you order and we'll have your cake ready there.

Is It Safe to Order a Cake Online for Dietary Needs?

Ordering online is the easiest way to handle dietary needs, because you can spell them out in writing and we confirm them back to you. According to Food Standards Australia New Zealand (FSANZ), egg and milk are among the priority allergens requiring strict labelling — and because our kitchen is entirely egg-free, the egg question is already settled before you ask.

A few honest points so you can order with confidence:

• Eggless by default — every flavour suits egg-allergic, Hindu vegetarian and Jain guests with no special request.
• Contains dairy — our cakes use milk products, so they're eggless but not vegan.
• Nuts and gluten — some flavours involve nuts, and standard cakes contain wheat; flag these when you order.
• Ask first — for any allergen beyond egg, message us before ordering for a full ingredient breakdown.

For a deeper look at ordering safely for an allergy, see our guide to eggless cake for an egg allergy.

Can You Order a Cake for Last-Minute or Same-Day Pick-Up?

Sometimes — but it's never guaranteed, so message us first. Our standard lead time is 48 hours because every cake is baked fresh to order rather than kept on a shelf. From our order data, last-minute requests are easiest to fill midweek and for simpler flavours and sizes; weekends and festival periods are the hardest because those slots book out earliest.

If you're in a genuine rush, send a WhatsApp message with your date, flavour and size and we'll tell you honestly what's possible. We'd rather say "not that one, but here's what we can do" than overpromise and disappoint you on the day. A flexible flavour choice and a standard round size give you the best chance of a quick turnaround.

Here's the practical tip from years of orders: the customers who never get caught out are the ones who order the moment they know the date — even a couple of weeks ahead. There's no downside to booking early, and it locks in your exact flavour, size and pick-up slot. Treat the 48-hour minimum as the floor, not the target, and last-minute stress disappears. For more planning detail, the custom cake ordering guide covers timelines for elaborate designs.
