"Eggless" tells you what's missing from a cake, but not what's actually inside it — and that gap is exactly where most people's questions start. A genuinely eggless cake replaces eggs' three jobs (moisture, binding and rise) with everyday dairy ingredients, not a mystery additive. Here's a full breakdown of what's really in a 100% eggless cake, and how to spot the difference between "eggless" as a marketing word and "eggless" as an actual recipe.
In August 2025, the National Allergy Centre of Excellence found that 8.2 million Australians — 30% of the population — now live with allergic disease. For a meaningful share of that group, knowing exactly what's in a cake isn't a curiosity, it's a genuine safety question. That's why we think a full ingredient breakdown is worth publishing, not just claiming.
- Buttermilk or yoghurt plus baking soda replaces eggs' role in our recipes.
- Eggless does not mean dairy-free — our cakes contain milk and butter.
- 8.2 million Australians (30%) now live with allergic disease (NACE, 2025).
- No product at Num Num's touches egg at any stage of preparation.

How Do You Replace Eggs in a Cake Recipe Without Losing Texture?
Eggs in a standard cake do three jobs at once: they add moisture, bind the dry ingredients together, and help the batter rise as they set in the oven. Replace only one of those functions and the cake fails somewhere — usually a dry crumb, a cake that collapses, or a dense, gummy texture. That's why home bakers who swap in a single egg substitute are often disappointed.
At Num Num's Bakery, the base substitution is buttermilk or yoghurt combined with baking soda and a touch of acid, usually from the batter's own ingredients. The acid and baking soda react to create the lift eggs would normally provide, while the buttermilk or yoghurt supplies moisture and helps bind the batter, much like eggs do. Getting the ratio right for each individual flavour, rather than using one formula for everything, is most of the recipe development work.
One thing we've learned through years of testing: a substitution ratio that works perfectly for a light Vanilla sponge often fails on a denser flavour like Chocolate or Red Velvet. Each of our 15 flavours has its own tested ratio rather than a single house formula applied across the board — that's the real difference between an eggless cake that tastes "fine" and one that tastes like the version everyone else is eating.
What Ingredients Does Num Num's Bakery Actually Use?
Every cake starts from the same core pantry: wheat flour, sugar, butter, milk powder, and a buttermilk or yoghurt-based egg replacer, plus baking soda and baking powder for lift. Flavour-specific ingredients — cocoa for Chocolate, freeze-dried mango for Mango, real coffee for Tiramisu — are added on top of that base, never as a substitute for it.
From our own kitchen practice, egg is never brought onto the premises in any form — not in the cake batter, not in a filling, not in a glaze. That's a stricter standard than "the cake recipe has no eggs," because it removes any risk of cross-contamination from a shared kitchen surface or utensil.
Core Ingredients in Every Flavour.
- Wheat flour — the structural base of the cake, standard across all flavours.
- Sugar — sweetness and moisture retention, adjusted per flavour.
- Butter — richness and texture; contains dairy.
- Milk powder — adds body to the batter and to buttercream fillings.
- Buttermilk or yoghurt — the primary egg replacer, providing moisture and binding.
- Baking soda and baking powder — leavening agents that create rise without eggs.
- Vanilla extract — a base flavour note used even in non-vanilla cakes.

We also keep the same standard for buttercream fillings and icing, not just the sponge itself. A common misconception is that the cake batter might be eggless while a shop-bought filling or icing sugar mix used on top isn't — that's not how we work. Every component that goes into the finished cake, from the base sponge to the final piped decoration, is made in-house from the same egg-free pantry.
Hebbars Kitchen (7.8M subscribers) demonstrates the buttermilk-and-baking-soda technique behind an eggless vanilla cake — the same principle behind every flavour we make.
Why Do Some "Eggless" Cakes Still List Egg-Derived Ingredients?
Some bakeries use "eggless" to mean the cake batter itself has no whole eggs, while a pre-made glaze, fondant, or filling used elsewhere in the same cake still contains an egg-derived additive such as lecithin (labelled E322) or albumin. For someone managing a genuine egg allergy, that distinction is the difference between a safe cake and a dangerous one.
Under Australian food labelling rules, eggs are one of the eight priority allergens set out by Food Standards Australia New Zealand (FSANZ), and any egg-derived ingredient must be declared on a product label. That's a useful check if you're ever buying a packaged "eggless" product rather than ordering from a bakery you can ask directly.
Eggs are one of the eight priority food allergens under Australian food standards, and any egg-derived additive — including lecithin or albumin used in a glaze or filling — must be declared on the label (Food Standards Australia New Zealand). Reading past the word "eggless" on the front of a package is genuinely worth the extra thirty seconds for anyone managing an egg allergy.
At Num Num's, we sidestep that ambiguity entirely — every component of every cake, from the sponge to the filling to the finish, is made without egg or egg-derived ingredients from the ground up, not assembled from a mix of eggless and non-eggless parts.
Message us on WhatsApp and we'll send a complete, honest ingredient breakdown before you order — no guesswork, no vague labels.
Are Eggless Cake Ingredients Safe for Allergies Beyond Eggs?
Removing eggs solves exactly one allergen risk — it doesn't make a cake allergen-free across the board. Our cakes still contain dairy (milk powder, butter) and wheat as standard ingredients, and some flavours involve nuts, so egg-free is not the same claim as nut-free or gluten-free.
From our order data, the most common follow-up question after "is it eggless" is "does it have nuts" — usually from a parent ordering for a school event. We keep a running note of which flavours are naturally nut-free and flag it clearly when you ask, rather than making anyone guess from the flavour name alone.
We offer gluten-free options on request, and can talk through what's realistic for a dairy-reduced order, though we're not a dedicated dairy-free bakery. For severe or anaphylactic allergies, always confirm your full requirements with us directly and follow your own medical advice — we recommend Allergy & Anaphylaxis Australia as an authoritative resource for allergy management more broadly.
Being genuinely egg-free at the kitchen level also matters for cross-contamination beyond eggs themselves. Nut-containing flavours like Ferrero Rocher are prepared with separate tools where practical, and we're upfront when a flavour simply can't be made nut-free due to how it's built. If a specific piece of equipment or preparation step matters for your situation, ask us directly — we'd rather explain our actual kitchen practice than offer a generic reassurance.
How Do Eggless Cake Ingredients Change Across Different Flavours?
The egg-replacer base stays consistent, but the flavour-specific ingredients shift noticeably from one cake to another. Chocolate relies on real cocoa solids for depth rather than artificial flavouring. Mango uses fruit puree and freeze-dried mango pieces rather than a synthetic essence, which is part of why the flavour tastes genuinely fruity rather than syrupy.
Rasmalai draws on milk solids, cardamom and a light rosewater note to echo the traditional South Asian dessert it's named after. Ferrero Rocher builds in hazelnut praline and a chocolate ganache layer, while Tiramisu uses real brewed coffee and a mascarpone-style cream filling rather than a coffee-flavoured syrup. None of these substitutions touch the core egg-replacer system — they sit entirely in the flavour and filling layer.
From years of recipe testing, the flavours that took the longest to get right weren't the simple ones like Vanilla or Chocolate — they were flavours like Ferrero Rocher and Tiramisu, where a rich filling has to hold its shape and texture without any egg-based custard or curd to fall back on. Getting a stable, sliceable mascarpone-style filling without eggs took considerably more testing than the sponge itself.
If a specific ingredient matters to you — a particular allergen, a preference around artificial flavouring, or a question about where an ingredient is sourced — ask us directly for the flavour you're considering. We'd rather answer a detailed question upfront than have you find out something doesn't suit you after the cake is cut.
How Do I Order Once I Know What's Inside?
From our experience taking orders across both locations, most customers who ask detailed ingredient questions end up ordering within the same conversation, once they have clear answers rather than a vague reassurance.

Frequently Asked Questions
What replaces eggs in an eggless cake?
At Num Num's Bakery, we use buttermilk or yoghurt combined with a leavening agent such as baking soda and a small amount of acid, which mimics the moisture, binding and rise eggs normally provide. The exact ratio varies by flavour to get the texture right every time.
Are eggless cakes dairy-free too?
No — our cakes are 100% egg-free but do contain dairy, including milk powder and butter. If you need a dairy-free cake as well as egg-free, message us before ordering so we can talk through what's realistic for your chosen flavour.
Why do some cakes labelled "eggless" still contain egg-derived ingredients?
Some bakeries use the term loosely to mean the batter has no whole eggs, while a pre-made glaze or filling still uses an egg-derived additive like lecithin (E322). At Num Num's, no product, ingredient, or preparation surface ever involves egg in any form.
What allergens are in Num Num's eggless cakes besides eggs?
Our cakes contain dairy (milk, butter) and wheat as standard, and some flavours involve nuts. We offer gluten-free options on request. Always tell us your full allergy profile when ordering so we can advise honestly on what's actually suitable for you.
Do eggless cake ingredients cost more than a regular cake?
Not significantly — buttermilk, yoghurt and baking soda are inexpensive, everyday ingredients, no more costly than eggs would be. Any price difference in an eggless cake usually comes from the extra recipe development and testing time behind it, not the raw ingredients themselves. See our cake price guide for typical costs.
