Mermaid cake decorations for birthday parties

Mermaid-themed birthday cakes are one of the most popular cake styles for girls' parties in Australia — and it's easy to see why. The colour palette (teals, purples, pinks, and iridescent shimmers) translates beautifully to cake decorating, and there are products at every skill level to pull the look off. At Baking Pleasures, we stock a full range of mermaid cake decorations including edible cake toppers, themed sprinkle mixes, lustre dusts, shimmer sprays, food colouring, moulds, and baking cups — everything you need to create a mermaid birthday cake or cupcake set from scratch.

Mermaid cake toppers

Edible mermaid cake toppers

Our edible mermaid cake toppers are printed on premium icing sheets in mermaid character designs — available in standard cupcake sizes for individual toppers and a full round size for the main birthday cake. These food-safe icing image toppers are completely edible, peel-and-place, and deliver a vibrant, high-resolution finish on buttercream or fondant. For the full range of pre-printed character designs, browse our edible cake toppers collection.

Mermaid figurine and non-edible toppers

For a three-dimensional mermaid cake topper, we stock decorative mermaid and ocean-themed figurine toppers that sit on top of the cake as a keepsake. These non-edible toppers are great for display or as a take-home gift for the birthday child after the party. Browse our full cake toppers range for more decorative topper styles and characters.

Mermaid sprinkles

The Sprinks Mermaid Tales Sprinkles (70g) are a dedicated mermaid-themed sprinkle mix combining iridescent sequins, shell shapes, and star pieces in the signature pearlescent, teal, and pink tones of a mermaid palette. Scatter them on cupcakes, cakes, and donuts for an instant under the sea theme with minimal effort. For a broader selection of pearl and iridescent sprinkle styles, browse our full sprinkles range.

Lustre dust and shimmer for mermaid cakes

Edible lustre dust

The pearlescent, iridescent finish that defines a mermaid cake comes from edible lustre dust. We stock Sprinks lustre dusts in the key shades for mermaid cakes:

• Pearl — for an all-over shimmer on white or pale-coloured fondant or buttercream
• Champagne — a warm iridescent gold tone that works well with blush and rose-gold mermaid palettes
• Seafoam and aqua tones — for teal and ocean-coloured accent details

Dry dust directly onto fondant or chocolate surfaces, or mix with Colour Mill Bakers Booze to paint on as an edible metallic finish.

Shimmer spray

The Sprinks Shimmer Dust Pump Spray in Pearl is one of the quickest ways to add a mermaid-style shimmer to a finished cake. Hold the non-aerosol pump spray 10–20cm from the surface and apply in short, gentle bursts. It works on fondant, buttercream, and chocolate surfaces and is completely edible, vegan, and sugar free. A single 4g canister covers a standard celebration cake with coverage to spare.

Food colouring for mermaid cakes

A mermaid cake palette typically draws from teals, aquas, sea greens, purples, and soft pinks — with a white or pastel base and iridescent shimmer layered on top. We stock the key shades in both Colour Mill oil-based colouring (for chocolate, candy melts, and oil-based buttercream) and Chefmaster Liqua-Gel (for fondant and royal icing):

• Teal / Ocean Blue — Colour Mill Oil Based, Colour Mill Aqua Blend, Chefmaster Liqua-Gel Teal
• Sky Blue / Aqua — Colour Mill Oil Based Sky Blue, Colour Mill Aqua Blend Sky Blue
• Purple / Violet — Colour Mill Oil Based, Chefmaster Liqua-Gel Violet
• Soft Pink / Coral — Colour Mill Oil Based, Colour Mill Aqua Blend

Mermaid moulds and ocean-themed tools

Shells, starfish, seahorses, and coral shapes are the building blocks of a detailed mermaid cake. We stock a range of silicone ocean moulds for casting fondant or chocolate sea-themed decorations, as well as shell and fish-shaped cookie cutters for mermaid-themed cookie sets. Browse our full moulds range for all ocean and character mould options.

FAQs about mermaid cake decorations

What mermaid cake toppers are available?

Baking Pleasures stocks edible icing image toppers (pre-printed mermaid character designs in cupcake and full cake sizes) and decorative non-edible mermaid figurine toppers. The edible icing toppers are peel-and-place and completely safe to eat. For a personalised mermaid design, our custom edible images service lets you upload any design and have it printed on a food-safe icing sheet.

How do I get the shimmer effect on a mermaid cake?

There are two main approaches. For a full-coverage shimmer over a pale fondant or buttercream base, use the Sprinks Pearl Shimmer Dust Pump Spray — hold it 10–20cm from the surface and spray in short bursts. For a more controlled, painted metallic finish on specific details, mix a pearl or aqua lustre dust with Colour Mill Bakers Booze and apply with a food-safe brush. Combining both techniques (shimmer base, painted details) gives the most professional mermaid finish.

What colours do I need for a mermaid birthday cake?

A classic mermaid palette uses teal, aqua, purple, and soft pink on a white or pale base, with iridescent shimmer across all colours. For a sunset mermaid palette, swap teal for coral and add gold or champagne lustre. We stock all key shades in Colour Mill oil-based colouring (best for chocolate and oil-based buttercream) and Chefmaster Liqua-Gel (best for fondant and water-based buttercream). See the full range in our food colouring collection.

What mermaid sprinkles are available?

The Sprinks Mermaid Tales Sprinkles (70g) are a dedicated mermaid sprinkle mix with iridescent sequins, shell shapes, and star pieces in teal, pink, and pearl tones. For a broader mix, combine them with pearl edible balls or iridescent glitter shapes from our edible sprinkles range to build a custom mermaid sprinkle blend.

Can I get a custom mermaid cake topper?

Yes — our custom edible images service lets you upload any mermaid-themed image (including personalised designs with a name and age) and have it printed as a food-safe icing sheet topper. This is the best option for a one-of-a-kind mermaid birthday cake. Custom edible images are available in standard cupcake sizes and full cake sizes.

What other mermaid-themed party cakes can I make with these decorations?

The same mermaid cake decorating products work equally well for under the sea birthday cakes, ocean-themed party cakes, and beach celebration cakes. The ocean moulds, shimmer sprays, and teal and aqua food colouring also cross over nicely with a unicorn cake palette if you're going for an iridescent, fantasy aesthetic. For a completely custom look, pair mermaid sprinkles with a hand-painted lustre dust finish and shell-moulded fondant decorations.
