Someone's birthday is next Tuesday, the team WhatsApp thread already has three "who's organising the cake?" messages, and nobody wants to be the person who orders a cake half the office quietly won't eat. That's the exact gap this guide is for — not a catered corporate function with a purchase order and an events coordinator, but the everyday reality of one colleague, or a small chip-in group, sorting out a single cake for a desk, a team, or a floor.
Num Num's Bakery bakes every cake 100% eggless as standard, across all 15 flavours, from two Sydney pickup locations. That single fact solves the office-birthday problem cleanly: nobody has to check ingredients, nobody has to sit the cake out, and nobody organising it has to become an amateur allergist. Message +61 425 697 725 on WhatsApp and the whole thing is usually sorted inside a few minutes.
- Every cake is 100% eggless by default — no substitution request needed for a mixed office.
- An 8-inch cake serves roughly 15–20 people; a 6-inch suits a small desk group.
- Order via WhatsApp with 48 hours notice — no purchase order or minimum spend required.
- Pick up from Harris Park or Riverstone — message +61 425 697 725 to confirm.
Why Choose an Eggless Cake for a Mixed Sydney Office?
According to the 2021 ABS Census, over 40% of Greater Sydney residents were born overseas and close to half speak a language other than English at home. Translate that into an average open-plan office and the maths is simple: almost any birthday cake run touches a Hindu vegetarian colleague, a Jain teammate, someone managing an egg allergy, or a Sikh staff member whose dietary code excludes eggs, often in the same shout-out.
Most workplaces don't ask people to declare their dietary background before a cake gets ordered — and they shouldn't have to. An eggless-by-default bakery removes that awkward moment entirely. Nobody has to raise a hand, nobody has to explain a religious or medical reason out loud in front of the team, and nobody quietly skips the slice while everyone else digs in.
The real advantage of "everything is eggless" isn't dietary accommodation — it's the absence of a conversation. Standard bakeries treat egg-free as a special request, which means someone has to ask for it and someone else has to notice they asked. When the whole menu is eggless, that entire social friction point simply disappears.
This matters more in a workplace than almost anywhere else. A birthday dinner is chosen company; an office birthday cake shows up on a desk in front of people you didn't choose to sit next to. Getting it wrong is more visible, not less. An eggless-first bakery takes that risk off the table before the cake is even ordered.
How Do You Order a Birthday Cake for the Office in Sydney?
From our order data for office and workplace celebrations across Sydney, the process almost always starts the same way — one colleague messages WhatsApp on behalf of the group, sometimes solo, sometimes after a quick chip-in via a shared expense app. It takes under five minutes and doesn't need sign-off from anyone above the desk it's for.
- Pick a flavour and size: Browse the full range on the Our Cakes page, or just tell us the headcount and we'll recommend one.
- Message WhatsApp: Send +61 425 697 725 your flavour, size, the date, and which pickup location works — Harris Park or Riverstone.
- Give 48 hours notice: Standard orders need at least two days. For a name written in fondant or a small custom design, ask early in the week.
- Collect and surprise the desk: We confirm everything in writing so there's no mix-up on the morning of the party.
There's no minimum order, no company account, and no need to loop in a facilities or events team for a single cake. See the Order Online page for a full sizing and pricing guide before you message us.
What Size Cake Do You Need for an Office Party?
From our internal order data across hundreds of workplace orders, an 8-inch round comfortably serves 15–20 people with a standard slice size, which covers most single-team office birthdays without leftovers piling up in the fridge. Smaller desks and larger floors both need different sizing, so getting it right up front saves an awkward second run to the shops.
If your office spans 40 or more people, a single 12-inch is possible but a two-tier arrangement or two separate cakes often slices more cleanly and travels better between desks. Not sure where your headcount lands? Message us the number and we'll confirm the right call before you commit.
Which Flavours Work Best for a Desk or Office Birthday?
From our order data, Chocolate remains the single most-ordered office flavour, followed closely by Vanilla and Ferrero Rocher, because all three read as safe, crowd-pleasing choices when you don't know everyone's individual taste. Office orders skew toward flavours that won't polarise a room of 15 to 40 people with different palates.
Beyond the four leaders, the full menu covers every taste on a team: Butterscotch and Black Forest & White Forest for a nostalgic, adult-leaning celebration, Mango, Strawberry, Blueberry and Pineapple for a lighter, fruit-forward slice, Rasmalai for teams with a strong South Asian contingent celebrating a cultural milestone alongside the birthday, and Tiramisu or Cookies & Cream when the office wants something a little different from the usual chocolate-and-vanilla rotation.
See the full Our Cakes page for photos of every flavour before you decide. If two flavours are tied in the group chat vote, message us — we can often split a single cake or run two smaller sizes side by side.
How Is Ordering a Single Office Cake Different From a Catered Corporate Event?
An office birthday cake and a corporate catering order look similar on the surface but move through completely different channels. One is a single colleague messaging WhatsApp for one cake and a same-week pickup; the other involves multiple cakes, branding, invoicing, and a lead time measured in days rather than hours. Treating them the same way slows down both.
From our order records, single office-birthday cakes typically come through as an individual WhatsApp order placed one to three days out, paid for by one person or a quick group chip-in. Multi-cake, branded corporate catering — the kind covered on our corporate cakes guide and our corporate events post — comes with a longer lead time and a company contact confirming the booking.
If your situation is genuinely the bigger one — end-of-year functions, branded logo cakes, or multiple cakes across departments — those two guides walk through bulk pricing, fondant logo work, and 5–7 day lead times in more detail. For everything else, one desk, one cake, one WhatsApp message is all this guide is about, and it's the far more common request.
Placing more than one cake for a bigger event? Our bulk order guide covers multi-cake pricing. Need something the same week with no lead time to spare? The same-day cake guide explains what's realistically possible on short notice. Whichever guide fits, the WhatsApp number stays the same — we'll point you to the right process once we know the size of what you're planning.
What Do HR Teams and Office Managers Need to Know Before Ordering?
Under the Food Standards Australia New Zealand (FSANZ) framework, eggs sit among the eight priority food allergens that require clear labelling and cross-contamination controls in Australian food preparation. An HR team ordering on behalf of a floor should know the eggless claim covers exactly that risk, and no further.
Our kitchen doesn't use eggs in any product, preparation surface, or piece of equipment, which removes the egg cross-contamination pathway completely. That said, our cakes still contain dairy (milk powder and butter) and some flavours involve nuts, and standard sponge contains wheat — we are not a nut-free, dairy-free, or gluten-free bakery. If anyone on the team has an allergy beyond eggs, including a severe or anaphylactic one, flag it when you message us and follow that person's own medical advice on top of what we can tell you about ingredients.
For workplaces managing food safety more broadly around shared celebrations, NSW Health's food safety guidance is a useful general reference — particularly around how long cake should sit unrefrigerated on a shared kitchen bench before a 3pm team celebration.
Larger organisations sometimes ask whether a single office order needs the same paperwork as a catered function. It doesn't. A one-off cake for a birthday, farewell, or work anniversary is a routine purchase, not a catering contract, so there's no need to route it through procurement unless your workplace specifically requires receipts for expense claims — which we're always happy to provide.
- Egg-free, not allergen-free: covers eggs specifically, not dairy, nuts, or gluten.
- No formal kosher or halal certification: we are not a certified kosher or halal kitchen — mention any certification requirement before ordering.
- Tell us about severe allergies directly: we'll give you an honest ingredient breakdown for the exact flavour you choose.
- Ask about design constraints: some decorative elements use nuts (Ferrero Rocher) — easy to substitute if flagged early.
How Much Does an Eggless Office Birthday Cake Cost in Sydney?
From years of taking Sydney office orders, the most common budgeting mistake is guessing a size before confirming headcount, then discovering half the floor is on leave that week. Message us the real expected number of people, not the total headcount — you'll almost always land on a smaller, cheaper size than you first assumed.
Pricing scales with size and design complexity rather than flavour — a simple 6-inch buttercream cake sits at the lower end of the range, while a larger 10 or 12-inch with fondant decoration or an edible logo costs more. There's no separate "corporate surcharge" for ordering to an office address, and no minimum spend for a single-cake order.

Frequently Asked Questions
How do I order an eggless cake for an office birthday in Sydney?
Message +61 425 697 725 on WhatsApp with your chosen flavour, cake size, the date you need it, and whether you'll collect from Harris Park or Riverstone. Standard notice is 48 hours. We confirm every order in writing before pickup so there's no last-minute surprise for the office.
What size cake should I order for an office party of 15 to 20 people?
An 8-inch round comfortably serves 15 to 20 people with standard slices. For a smaller desk group of 8 to 10, a 6-inch is usually enough. Message us on WhatsApp with your headcount and we'll confirm the right size and price for your office birthday order.
Are Num Num's cakes safe for colleagues with an egg allergy?
Every cake is made in a 100% egg-free kitchen, removing the egg cross-contamination pathway entirely. Cakes do still contain dairy (milk powder, butter) and some flavours involve nuts, so they aren't allergen-free beyond eggs. Tell us about any allergy when ordering so we can advise honestly.
Can one person order a cake for the office without a formal group order?
Yes. Most office birthday orders come from a single colleague or a small chip-in group messaging WhatsApp directly — there's no minimum order size, no purchase order paperwork, and no need to go through a corporate events process for one desk-sized cake.
