Choosing wedding cake icing is about much more than appearance. The finish affects flavour, texture, decoration, transport, display conditions and how the cake performs on the day.
Quick answer: Buttercream is popular for soft, contemporary cakes; fondant creates a smooth surface suited to precise and sculptural designs; ganache offers a rich chocolate finish and is also commonly used beneath other finishes; royal icing is associated with traditional detailed piping; cream cheese frosting provides a tangy flavour but requires careful temperature management; and marzipan is an almond-based paste traditionally used beneath icing or for decorative work. No icing should be assumed to be heatproof, especially during a Melbourne summer.
Wedding Cake Icing & Frosting Comparison
| Finish | Taste & texture | Appearance | Design potential | Temperature considerations | Often suits |
|---|---|---|---|---|---|
| Buttercream | Creamy, buttery; sweetness varies by recipe | Smooth, soft or textured | High, including piping | Can soften in heat | Modern, romantic, minimalist and floral cakes |
| Fondant | Sweet, soft-chewy outer layer | Very smooth with crisp-looking edges | Very high | Still affected by heat, humidity and the cake beneath it | Formal, sculptural and highly precise designs |
| Ganache | Rich chocolate | Smooth, glossy or matte depending on application | Moderate to high | Chocolate and cream remain temperature sensitive | Chocolate-forward and contemporary cakes |
| Royal icing | Sweet and firm when dry | Crisp and highly detailed | Exceptional for fine piping | Hardens as it dries, but the complete cake still needs appropriate conditions | Traditional, vintage and intricate designs |
| Cream cheese frosting | Tangy, creamy | Soft | More limited for structural detail | Requires careful refrigeration and food-safety management | Carrot, red velvet and spice cakes |
| Marzipan | Sweet almond flavour | Smooth when rolled | Useful for covering and modelling | Depends on the complete cake and final finish | Traditional fruit cakes and decorative work |
This table is a practical comparison rather than a guarantee of performance. Recipes, fillings, internal structure, room temperature, humidity, transport and display time can all affect a wedding cake.
What Is the Difference Between Icing and Frosting?
The terms are often used interchangeably in Australia. In general baking language, frosting often refers to a thicker, softer coating such as buttercream or cream cheese frosting, while icing can describe finishes that set more firmly, such as royal icing.
For wedding planning, the terminology matters less than understanding the exact product your cake maker intends to use. Ask about its flavour, texture, ingredients, appearance and how it will behave in your venue conditions.
1. Buttercream Wedding Cakes
Buttercream is one of the most versatile contemporary wedding cake finishes. It can be smoothed for a minimalist look, deliberately textured, piped into decorative patterns or used beneath flowers and other embellishments.
American Buttercream
Typically made from butter and icing sugar, American-style buttercream is rich, sweet and relatively straightforward. It is well suited to piping and can be flavoured and coloured easily.
Swiss Meringue Buttercream
Swiss meringue buttercream uses egg whites and sugar heated together before being whipped and combined with butter. It is known for a silky texture and is usually perceived as less sweet than traditional American buttercream.
Italian Meringue Buttercream
Italian meringue buttercream incorporates hot sugar syrup into whipped egg whites before butter is added. It creates a smooth, light-textured buttercream and is widely used by professional cake makers.
Other Buttercream Styles
French buttercream, ermine frosting and other variations also exist. Couples generally do not need to choose a recipe by name before speaking with a cake designer. Taste the cake and ask why a particular buttercream is being recommended for your design and conditions.
Buttercream Advantages
- Soft, creamy texture.
- Can be smooth, rustic, textured or piped.
- Works with a wide range of flavours.
- Well suited to many contemporary wedding cake styles.
Buttercream Considerations
- Butter-based finishes can soften as temperatures rise.
- Very sharp or sculptural effects may be easier with other finishes.
- Outdoor display times need to be planned carefully.
2. Fondant Wedding Cakes
Rolled fondant is a pliable sugar-based icing rolled into a sheet and placed over a prepared cake. It is particularly useful when couples want an exceptionally smooth surface, crisp-looking edges, embossed details, pleating or sculptural decoration.
Fondant is normally only one part of the cake’s exterior system. The cake beneath it may be prepared with ganache or another suitable coating before the fondant is applied.
Fondant Advantages
- Creates a very smooth, polished appearance.
- Excellent canvas for detailed decoration.
- Useful for architectural, embossed and sculptural designs.
- Can create visual precision that is difficult to achieve with softer finishes.
Fondant Considerations
- Its sweet, soft-chewy texture is not everyone’s preference.
- A flawless finish requires considerable skill.
- Fondant is not a licence to leave a wedding cake in direct summer sun.
- Heat, humidity, condensation and the ingredients beneath the fondant still matter.
3. Ganache Wedding Cakes
Ganache is traditionally made from chocolate and cream. Depending on the chocolate-to-cream ratio and how it is handled, it can be used as a filling, exterior finish or firm layer beneath fondant.
Dark, milk and white chocolate produce different flavours and working properties. Cake makers can also flavour ganache or whip it for a lighter texture.
Ganache Advantages
- Rich chocolate flavour.
- Can produce smooth, contemporary finishes.
- Useful as both filling and exterior preparation.
- Pairs naturally with chocolate and mud cakes.
Ganache Considerations
- Chocolate and cream are temperature sensitive.
- The texture changes significantly between chilled and warm conditions.
- It may be richer than some couples want for every layer.
4. Royal Icing: The Traditional Wedding Cake Finish
Royal icing is made primarily from icing sugar combined with egg white or a suitable egg-white preparation. It dries firm and can be piped into exceptionally fine decorative work.
Royal icing has an important place in Australian wedding cake history. Traditional fruit cakes were commonly covered with marzipan and finished with royal icing, sometimes featuring elaborate lacework, lattice panels, scalloped swags, shell borders, beadwork and piped flowers.
Royal Icing Advantages
- Exceptional for detailed hand piping.
- Sets firm and holds fine decorative work.
- Creates a distinctive traditional or vintage appearance.
- Can demonstrate a level of manual craftsmanship rarely seen in minimalist finishes.
Royal Icing Considerations
- Sets much harder than buttercream.
- Can be very sweet.
- Detailed work requires specialist skill and considerable labour.
- It is less common on contemporary Australian wedding cakes than it once was.
5. Cream Cheese Frosting
Cream cheese frosting has a tangy flavour that pairs particularly well with carrot, red velvet and spice cakes. It generally creates a softer finish than fondant or royal icing.
Because cream cheese is a perishable dairy ingredient, refrigeration, recipe formulation, display time and food safety need to be discussed with the cake maker and venue. It should not be selected for a warm wedding simply because a particular recipe is described as “stabilised”.
Best Reasons to Choose Cream Cheese Frosting
- You genuinely prefer its tangy flavour.
- It complements the chosen cake flavour.
- Your cake maker and venue can manage the required temperature conditions.
6. Marzipan
Marzipan is a sweet almond-based paste made principally from almonds and sugar. It has traditionally been used to cover fruit cakes before the final icing layer and can also be shaped into decorative elements.
It should not be confused with royal icing. Marzipan is pliable and almond-flavoured; royal icing is a sugar-based icing that dries firm and is particularly suited to detailed piping.
Because almonds are a tree nut, couples should also consider guest allergies and discuss allergen management with their cake maker.
7. Naked and Semi-Naked Wedding Cakes
A naked cake uses little or no icing on the outside, leaving the cake layers and filling visibly exposed. A semi-naked cake uses a thin coating that allows parts of the cake beneath to remain visible.
These finishes became particularly popular for rustic, garden, winery and relaxed weddings. They can look beautiful with restrained flowers, fruit or minimal decoration.
Less exterior icing does not automatically make a cake easier to manage. Exposed cake can lose moisture, and fillings may still be temperature sensitive. Ask the cake maker how long the cake can safely and attractively remain on display.

Buttercream vs Fondant: Which Is Better?
Neither is universally better.
Choose buttercream if you prefer a creamy texture, softer appearance, textured finish or contemporary piped style.
Choose fondant if your design depends on a highly polished surface, crisp geometry, embossed details or sculptural decoration.
Cost should not be decided by icing type alone. An intricate piped buttercream cake can involve more labour than a simple fondant design. Our 2026 Wedding Cake Cost Guide explains the other factors that affect the quote.
What Is the Best Wedding Cake Icing for a Melbourne Summer?
No wedding cake icing should be assumed to be heatproof.
Melbourne summer conditions can create problems for buttercream, chocolate, ganache, fondant-covered cakes and temperature-sensitive fillings. Even if the exterior appears stable, the complete cake still needs to be considered.
Tell your cake maker:
- whether the reception is indoors or outdoors;
- whether the room is air-conditioned;
- when the cake will be delivered;
- how long it will be displayed;
- whether direct sunlight can reach the cake table;
- whether suitable refrigeration is available; and
- when the cake is expected to be cut and served.
For hot-weather weddings, the safest strategy is generally to manage the cake’s environment and display time rather than choosing an icing because it has been described as “melt-proof”. Positioning the cake away from direct sunlight, delaying display where practical and coordinating delivery with the venue can be more important than the label applied to the exterior finish.
Choosing Icing to Match Your Wedding Style
Modern or Minimalist
Smooth buttercream, restrained fondant or ganache can all work. The best choice depends on whether you want soft organic texture or architectural precision.
Formal or Black Tie
Fondant can work particularly well for crisp, highly controlled designs, while royal icing can create an entirely different form of formal elegance through traditional piping.
Romantic or Floral
Buttercream provides a soft base for floral styling, but fondant can also work beautifully when a cleaner, more polished backdrop is preferred.
Vintage
Lambeth-style buttercream piping and traditional royal icing can both create vintage references, although the techniques and final textures are very different.
Rustic, Winery or Garden
Textured buttercream, semi-naked and naked finishes often complement relaxed settings, subject to weather and display conditions.
Matching Icing with Cake Flavour
Appearance matters, but the icing should work with the cake when it is actually eaten.
- Chocolate or mud cake: ganache or chocolate buttercream can reinforce the chocolate flavour, while fondant may be used over an appropriate prepared surface for design reasons.
- Vanilla: highly versatile and compatible with buttercream, fruit fillings, ganache and fondant-covered designs.
- Lemon and citrus: often pair well with lighter buttercream and complementary fruit fillings.
- Carrot or spice cake: cream cheese frosting is a classic flavour pairing where temperature management permits.
- Traditional fruit cake: marzipan and royal icing have a long historical association with this style.
Whenever possible, taste the icing together with the cake and filling rather than judging each component separately.
Fresh Flowers, Allergens and Food Safety
Not every flower is suitable for contact with food. If fresh flowers will be used, ask who is supplying and preparing them and how direct contact with the cake will be managed. Your florist, cake maker and venue should understand who is responsible for the final placement.
Dietary labels also need context. A cake described as gluten-free, dairy-free, egg-free, vegan or nut-free may still be produced in an environment where other allergens are handled. For serious allergies or coeliac disease, ask specifically about ingredients, preparation and cross-contamination procedures.
Temperature-sensitive ingredients such as cream cheese, fresh cream and some fillings also require appropriate storage and display management. Follow the cake maker’s specific instructions rather than applying a generic rule to every wedding cake.
How to Choose Your Wedding Cake Icing
Choose buttercream if you want a creamy finish, soft contemporary appearance, texture or piping.
Choose fondant if your design relies on exceptionally smooth surfaces, defined edges, embossed work or sculptural elements.
Choose ganache if chocolate flavour is important or your cake designer recommends it as part of the cake’s filling or exterior structure.
Choose royal icing if you love traditional piped craftsmanship, heritage wedding cake design or intricate ornamental detail.
Choose cream cheese frosting if its flavour is a priority and the cake can be stored and displayed under appropriate conditions.
Choose a naked or semi-naked finish if you prefer a relaxed exposed-cake aesthetic and your cake maker considers it suitable for the venue, weather and display time.
What We Learned From Wedding Cakes at Brighton Savoy
During decades of weddings at Brighton Savoy, we watched wedding cake fashions change enormously.
In earlier decades, substantial fruit cakes covered in marzipan and detailed royal icing were familiar sights. Some featured remarkable hand-piped lacework, swags, borders and decorative details that represented many hours of skilled work.
Over time, chocolate mud cake, fondant, cupcakes, naked cakes, buttercream, croquembouche and increasingly individual designs became more common.
But the practical considerations never disappeared.
The cake still had to arrive safely, suit the room, remain in good condition until it was cut and ultimately taste good when served to guests.
That is why we would not choose icing from a photograph alone. Think about taste, venue conditions, season, delivery, display time and the skill of the cake maker as well as the finished appearance.
Once you know the finish you prefer, our guide to Melbourne wedding cake suppliers can help you compare cake makers and designers.

Wedding Cake Icing FAQs
What is the most popular wedding cake icing?
Buttercream and fondant are both widely used for contemporary wedding cakes, but there is no single best finish. The right choice depends on design, taste, venue conditions and the cake maker’s preferred techniques.
Is buttercream or fondant better for a wedding cake?
Buttercream is often preferred for taste and a softer contemporary appearance, while fondant is useful for exceptionally smooth surfaces and precise decorative work. Neither is automatically better.
Does fondant melt in hot weather?
Fondant should not be treated as heatproof. Heat and humidity can affect the fondant, the coating beneath it, fillings and the cake’s overall structure. Direct sunlight and long outdoor display times should be discussed with the cake maker.
Can you put fondant over buttercream?
Yes, depending on the cake maker’s technique and design. Fondant requires a properly prepared surface beneath it. Some professionals use buttercream, ganache or another suitable preparation.
What is the best wedding cake icing for summer?
There is no universally heatproof wedding cake icing. For a Melbourne summer wedding, professional advice about the complete cake, venue temperature, refrigeration, delivery and display time is more useful than choosing an icing by name alone.
What icing is best for detailed wedding cake piping?
Royal icing is particularly suited to very fine traditional piping and firm decorative details. Buttercream can also produce elaborate piping, including contemporary and Lambeth-inspired designs, but the final texture is different.
Can wedding cakes have different fillings on each tier?
Often yes. Many cake makers offer different flavour and filling combinations across tiers, subject to structural, dietary and production considerations.
Is royal icing still used on wedding cakes?
Yes. It is less dominant than it was in earlier generations of Australian weddings, but it remains an excellent choice for traditional cakes and highly detailed piped decoration.
Is marzipan the same as fondant?
No. Marzipan is principally an almond-and-sugar paste with a distinctive almond flavour. Fondant is a sugar-based icing used to create a smooth exterior finish.
Should a wedding cake be refrigerated?
That depends on the icing, filling, recipe and food-safety requirements. Follow the cake maker’s storage instructions and make sure the venue understands them before the wedding day.
About This Guide
Brighton Savoy’s connection with Melbourne weddings began in 1967. For decades, the property operated as a beachfront hotel, restaurant, function centre and wedding reception venue opposite Brighton Beach.
That experience included receiving, displaying, cutting and serving wedding cakes and working with couples and suppliers on the practical logistics behind them.
Brighton Savoy no longer operates as a hotel or wedding venue. Today, it is an independent Australian information platform combining first-hand hospitality experience with current consumer research.

Final Thoughts
The best wedding cake icing is not simply the finish that looks best in a photograph.
Buttercream, fondant, ganache, royal icing, cream cheese frosting and marzipan all have different strengths. The right choice needs to work with the cake flavour, design, venue, season, delivery plan and the way the cake will be displayed and served.
Start with the appearance you love, but taste the cake as well. Then ask your cake maker what will realistically work for your wedding.
A beautiful wedding cake should survive the journey, suit the room and still be enjoyable when the first slice reaches the plate.
