Eggless Cake Buttercream vs Fondant: Which Icing Should You Choose?

The icing decides how your eggless cake looks, feels and tastes the moment it hits the table. Two routes cover almost every cake: a soft finish — buttercream or fresh whipped cream — or a smooth, sculpted finish in fondant. They behave differently, cost differently and suit different occasions, so the choice is worth a minute's thought before you order.

Here's the good news for anyone who avoids eggs: at Num Num's Bakery, every finish is 100% eggless, the same as our sponges. Buttercream, fresh cream and fondant are all egg-free, so the decision is purely about taste and style — never about whether your guests can eat it. This guide compares the two on the things that actually matter.

Buttercream vs Fondant: What's the Difference?

Buttercream and fresh cream are soft, spreadable icings whipped onto the cake; fondant is a sweet, pliable sugar paste rolled into a sheet and draped over it for a smooth, matte finish. Buttercream gives a homely, piped or textured look and a light mouthfeel. Fondant gives a clean, sculptural surface that holds printed images, sharp edges and 3D shapes. Here's how they compare at a glance.

Neither is "better" in the abstract — they're tools for different jobs. The rest of this guide walks through taste, looks, durability and cost so you can match the finish to your cake. And remember: on the Our Cakes page, every option is eggless, so this is purely a style decision.

Which Tastes Better on an Eggless Cake?

For pure eating pleasure, most of our customers prefer buttercream or fresh cream. From our internal order data, soft-finish cakes outsell fondant-covered ones by a wide margin — roughly seven in ten of our cakes go out with a cream or buttercream finish. The reason is simple: cream is light, less sweet, and lets the eggless sponge and flavour come through.

Fondant tastes sweeter and firmer — a sugar shell rather than a creamy layer. Plenty of people happily eat it; plenty of others peel it back and enjoy the sponge and cream beneath. Crucially, the eggless cake inside tastes identical either way. Fondant changes the surface, not the crumb. If taste is your top priority, lean cream; if a flawless finish matters more, fondant earns its place. For more on what makes the sponge itself soft, see our guide to moist eggless cake texture.

Fresh Cream or Buttercream — Which Soft Finish?

From our internal order data, fresh whipped cream is the default soft finish on most of our eggless cakes, with buttercream chosen when a design needs more structure. Both are egg-free and both taste light, but they behave differently: fresh cream is airy and delicate, while buttercream is denser and firmer, which makes it better for piping detail and warm rooms.

Fresh cream suits fruit cakes, layered gateaux and anyone who finds heavy icing too sweet — it's the lighter, more refreshing option. Buttercream holds sharp swirls, rosettes and lettering, and survives a little longer out of the fridge, so it's the safer pick for a cake that has to sit out during a long party. If you're undecided, tell us the flavour and the setting and we'll match the cream to the cake. Fruit-forward flavours like Mango, Strawberry and Pineapple almost always shine brightest under fresh cream.

Which Looks Better — Fondant or Buttercream?

For sharp, sculptural or themed designs, fondant wins. Its smooth surface is the right canvas for clean edges, fine detail, edible images, 3D characters and the crisp tiers of a formal cake. If you want a flawless single colour, a printed photo or a sculpted shape — a number, a handbag, a cartoon — fondant is the practical choice.

Buttercream and fresh cream have their own beauty — soft swirls, piped florals, textured combing, a semi-naked finish, drips and fresh fruit. It reads as warm and handmade rather than polished and formal. For most birthdays, that look is exactly right. The honest answer is that the best-looking cake is the one whose finish matches the occasion: buttercream for relaxed celebrations, fondant for showpieces. Browse both styles among our custom cakes.

Which Holds Up Better in Sydney's Climate?

In heat, fondant is the more forgiving finish. A fresh-cream cake is perishable and should be kept refrigerated until close to serving — the NSW Health food safety guidance is to keep cream-based foods cold and minimise time in the temperature danger zone. On a hot Sydney afternoon, a cream cake left in the sun will soften quickly, while fondant stays put for longer.

That doesn't rule out cream for summer parties — it just means planning. Keep the cake boxed and refrigerated, transport it flat and cool, and bring it out shortly before the cut. For long outdoor events, a marquee, a tiered cake stand in the shade, or a fondant finish all help. If your celebration is outdoors in January, tell us when you order and we'll recommend the finish that will survive the day looking its best.

Is Buttercream or Fondant Cheaper?

As a rule, a buttercream or fresh-cream finish costs less than detailed fondant work. The difference isn't the icing itself so much as the labour: rolling, covering, smoothing and hand-modelling fondant detail takes far longer than piping cream. A simple fondant cover is close to buttercream in price, but sculpted figures, printed panels and multi-tier fondant designs add hours, and that's what you're paying for.

If budget is the deciding factor, a beautifully piped buttercream cake delivers maximum impact for the least cost — which is part of why it's our most-ordered finish. If the design is the whole point, fondant is worth the extra. Either way, price tracks size and detail more than the icing type, so the cleanest way to compare is to send us the design and headcount on WhatsApp for a quote. Our eggless cake size guide helps you settle on dimensions first.

It's also worth thinking about waste. A large fondant cover that guests peel off and leave on the plate is, in effect, money you've paid for decoration rather than dessert. For a cake where most people will eat every bite — a family birthday, an office celebration — a cream or buttercream finish puts your spend into the part everyone actually enjoys. Reserve fondant for the cakes where the look is doing real work: a themed showpiece, a tiered centrepiece, or a printed photo cake that needs a flawless canvas.

Which Should You Choose for Your Eggless Cake?

Choose by the job the cake has to do. As a quick decision guide drawn from the orders we make most:

• Kids' birthday, relaxed party — buttercream or fresh cream; light, crowd-friendly and cost-effective.
• Themed or character cake — fondant, for sculpted shapes, printed images and clean colour.
• Formal, tiered or wedding-style cake — fondant for crisp tiers, or a polished buttercream finish for a softer look.
• Hot outdoor event — fondant, or a well-planned, refrigerated cream cake brought out late.
• Flavour-first celebration — fresh cream, so the eggless sponge and flavour lead.

Still torn? You can have both — a fondant base with buttercream piping, or fondant accents on a cream cake is a common request. Send us your design idea and we'll suggest the finish, or combination, that suits it best.

Are Both Icings Eggless — and What's in Them?

Yes — at Num Num's, buttercream, fresh cream and fondant are all 100% egg-free, the same standard as our sponges. That matters more every year. As of August 2025, the National Allergy Centre of Excellence reported 8.2 million Australians — 30% of the population — now live with allergic disease, double the 2007 figure. An entirely egg-free kitchen means no egg in the cake, the cream or the fondant, and no egg cross-contamination on shared equipment.

To be clear on the rest: our cakes contain dairy (milk powder, butter and fresh cream), some involve nuts, and standard sponges contain wheat. Egg is a priority allergen under Food Standards Australia New Zealand (FSANZ) labelling rules, which is exactly the pathway our egg-free kitchen removes. We're an eggless bakery — not a vegan, nut-free or gluten-free one — so for serious allergies beyond egg, tell us when you order and follow your own medical advice.

How Do You Order an Eggless Cake in Sydney?

Ordering takes about five minutes on WhatsApp, and we confirm the design, finish and price in writing before you collect. The process is the same from either of our two shops.

1. Choose flavour and finish: Browse the Our Cakes page, pick a flavour, and decide buttercream/cream or fondant — or a mix.
2. Message us on WhatsApp: Send your brief to +61 425 697 725 with the size, design, date and pick-up shop.
3. Allow enough notice: 48 hours minimum; 4–5 days for tiered cakes, fondant figures or photo prints.
4. Collect and enjoy: Pick up from Harris Park or Riverstone, both 100% eggless kitchens. See the Order Online page for the full guide.

From our order history, the cakes that arrive looking exactly as planned are the fondant ones booked with a few days' lead time — sculpted detail can't be rushed. A buttercream cake, by contrast, is often comfortable at 48 hours' notice. So the finish you choose can also shape how early you should message us.
