The Biggest Kids Cake Trends of 2026

1. K-Pop Demon Hunters Cake

A year after it landed, this is still the theme we get asked about more than any other. Kids love the dramatic character art. Parents love that the palette of black, hot pink and purple makes styling the rest of the party pretty easy.

For the full effect, the Over the Top Decorations version piles on character toppers and layered colour, starting at A$69.95. Got a big crowd coming? The 2-tier K-Pop Demon Hunter cake starts at A$179.95.

2. Labubu Cake

Labubu started life as a Pop Mart collectable and somehow ended up clipped to half the schoolbags in Melbourne. As a cake theme it's an easy win, especially if your child already owns a few figures you can sit on the table next to it.

The 2-Tiered Tall Pink Labubu gives you plenty of height and a soft pink finish that suits most party setups.

3. Jellycat Cake

For little ones (and, honestly, plenty of older kids too), Jellycat has turned into its own look. The Jellycat Ice Cream Cake in Original White n Brown has that soft, cuddly feel, from A$79.95.

It's a sweet choice for a first or second birthday when you want something cute without loud cartoon colours.

Gaming Cakes With a Big-Screen Boost

4. Minecraft Cake

Minecraft never really went away, but the movie gave it a second wind. These days the whole class knows a Creeper on sight, not just the gamers. Pixel blocks are also dead easy to copy onto plates, napkins and lolly bags.

Start with the Minecraft Creeper Themed Cake from A$79.95. If your child would rather blow things up than build them, the Minecraft TNT Square Cake starts at A$99.95.

5. Super Mario Cake

The Super Mario Galaxy Movie was the first film of 2026 to pass US$1 billion at the global box office, and you can feel it at kids' parties. Stars and planets slot in nicely alongside the usual red, blue and yellow.

The 2 Tier Super Mario Ice Cream Cake starts at A$159.95 and holds its own as the centrepiece.

6. Roblox Cake

Roblox works a little differently, because every player has their own avatar and that's what kids want to see on the cake. The Roblox Avatar Cake (from A$79.95) is personalised with avatar-style detailing, so have a screenshot of your child's character handy when you order.

Cute Characters Having a Moment

7. Stitch Cake

Since the live-action Lilo & Stitch film, Stitch has popped up on everything from lunchboxes to pyjamas. The Stitch and Angel Ice Cream Cake pairs the blue and pink characters, from A$79.95. It's a handy option for siblings sharing a party, too.

8. Kuromi and Cinnamoroll Cakes

Hello Kitty is still loved, but more kids now ask for her Sanrio friends by name. Kuromi fans usually want black, purple and pink, and the Kuromi Heart Cake (from A$89.95) leans right into that.

Prefer something softer? The Cinnamoroll Cake Design #2 in Blue keeps things pastel blue and white, from A$79.95. You'll find the rest of the range in our Sanrio and Hello Kitty collection.

9. Gabby's Dollhouse Cake

A strong pick for the three-to-five crowd. Pink and purple do most of the work, and cat-ear headbands make cheap, cute party favours. See the Gabby's Dollhouse Cake, from A$79.95.

Anime and Superhero Picks for Older Kids

10. One Piece and Anime Cakes

Once kids hit nine or ten, anime starts creeping onto the birthday wish list. The One Piece Vintage Styled Cake (from A$79.95) mixes old-school piped borders with anime character detailing.

The best part is that you can upload your own design. So if your child has moved on to a different series by the time the party rolls around, the cake can move with them.

11. Avengers and Spidey Cakes

Superheroes never really drop off the list. If your child can't pick just one, the Avengers Themed Ice Cream Cake brings the whole team together, from A$79.95.

Younger fans who know Spider-Man from TV tend to love the cartoon-style Spiderman Spidey Cake, also from A$79.95. There's more in the Superhero Themed Cakes collection.

Sporty Cake Themes for 2026

12. FIFA World Cup 2026 Cake

The World Cup ran through June and July, and a lot of kids came out the other side completely soccer-mad. The FIFA 2026 Soccer World Cup Ice Cream Cake (from A$79.95) keeps that buzz going, and it suits a party with a backyard kick-around planned.

13. AFL Footy and Basketball Cakes

This is Melbourne, so footy was always going to make the list. Club designs like the Collingwood Magpies Footy Cake and the Hawthorn Hawks Footy Cake both start at A$79.95.

Basketball fans are well looked after too, from a simple Basketball Round Birthday Cake to NBA player designs. Browse the full Basketball Cakes collection or the Football and Soccer range.

Cake Style Trends (Not Just Characters)

14. Heart-Shaped Cakes

Heart cakes used to be a Valentine's Day thing. Now they've crossed over into kids' birthdays, especially in pastels. The Unicorn Heart Cake is a good example, from A$99.95, and there's a whole range of heart cakes to choose from.

15. Photo and Fully Custom Cakes

Some kids just won't fit into one box, and that's fine. A photo cake puts their face, their pet or their favourite character front and centre. A custom cake lets you blend a colour, a hobby and a character into one design.
