Step One
Using computer-aided design (CAD) to bring my ideas to life, each design is carefully developed around multiple requirements to ensure the final edible cake is cleanly formed and free from issues.
Step Two
Over 15 hours of printing, ensuring the settings produce a clean design!
Step Three
Food-grade silicone is used to create a mould from the 3D print, adhering to food-safety regulations.
Step Four
Not easy thinking of a new flavour, as each flavour goes through user testing to ensure it's the best version upon release.

Hello!
I'm the face behind Onyx Hive, your go-to spot for the most indulgent mousse cakes in Sydney! I started this sweet adventure in 2021 because I wanted to share my passion for unique, handcrafted cakes with you (that and I needed a job too!).
Every single thing you see on my website—graphics, photos, social media posts, writing, the cakes themselves, you name it—it's all me!
Yep, I’m a one-man show, and I even hand-deliver your cakes because, well, trust issues (but hey, that means they're in good hands!).
I bake each mousse cake from scratch. Not milking cows or harvesting wheat, but you get the idea.
You pick your cake, I craft it with love, and I deliver it straight to your door, so you can enjoy the good stuff!
Can’t wait to bake something sweet for you soon!

Standard cakes only, please see link below for eligible cakes. Cakes continuously being added. T&Cs apply
I bought the Matilda cake from Onyx Hive for my mum’s 72nd birthday on 11 October, and it was honestly the best chocolate cake I’ve had. Super moist, rich, and just really well made. Everyone loved it.I liked it so much that the next day I ordered their “Mystery Cake” to pick up this Friday. That should tell you everything.Great cakes, worth it, and I’m definitely coming back.
Looks and tastes perfectly!
Sent this to my sister for her birthday. She loved it! Will be ordering again soon :)
Ordered Sakura cake for our birthday celebration and was really impressed with finishing quality of the cake and was of delicious taste, appreciated by all our guests. Whole process was smooth from the start and was hand delivered by Dante within earlier provided timeframe. Highly recommend.
This cake was beautifully presented. Blew everyone away and then the flavour, my goodness the flavour and texture. I’d been looking for an interesting looking and well made cake for a while and was so impressed. I’ll definitely order again. I want to try all the flavours and shapes
⭐️⭐️⭐️⭐️⭐️
Absolutely loved it! I sent this Mango & Cream Cake to my brother for his birthday, and it was a huge hit. Everyone loved the beautiful presentation, and more importantly, the cake tasted amazing—fresh, light, creamy, and delicious.
It made his birthday celebration extra special. Would definitely order again and highly recommend it! 🎂🥭
My favourite is chocolate, hence I was so happy when I got the obsidian. So so good and so rich. Everyone loved it.
Amazing complexity and the chocolate melts in your mouth! Would recommend heating this up 10 seconds before eating. Wouldn’t definitely order again
First time ordering from Onyx Hive and we will definitely be ordering again. The Obsedian cake was amazing, so tasty, so moist and that mousse was out of this world. Very keen to taste the other flavours.
Honest review:
The entire cake was not sweet at all! The sakura mousse had a very light and creamy texture it didn't break it's shape either even though it was defrosted as instructed upon delivery . The sponge cake was airy and moist not dry like other places . The blueberry cream had just the perfect ratio of real fruit not a single sign of artifical taste. We loved the structural design of the cake very unique and every detail from the box to having a pull out tab which made it easier to take out , and the attention to each layer delivering its own flavour while also not over doing it made the experience so priceless !
I had the privilege of getting my hands on these cookies and damn they were good! I had them heated up in the microwave for about 15 seconds and the chocolate did melt inside but my friend like it not heated.
They were so easy to eat!!! Worth it!!! PEW PEWWWWW
The cake was absolutely stunning! The black and gold design was elegant, beautifully crafted, and looked exactly as we had hoped. the cake was moist, rich, and delicious. Thank you for your attention to detail, excellent communication, and fantastic service. We couldn’t be happier and will definitely order again. Highly recommended!
Thank you for helping make our AETC 3rd Anniversary celebration extra special! 🎂✨
Not overly sweet, but just sweet enough, beautiful cake. Everyone enjoyed the Ivory cake!
The cake was especially tasty, it is a wonderfull recommendation for those with a sweet teeth .Other than that the cake was very soft and easy to chew. It lookes very pleasing to the eye , I have absolutely no regrets about buying this cake it was an exceptional experience and everyone else who ate the cake says the same. Although the cake is a bit too sweet, it was overall a very pleasant treat, for someone who doesn't have cake often
Everyone, including kids came back for seconds, but some missed out!
Birthday girl was very touched with such a beautifully presented cake 🩷
The cake looked amazing and tasted delicious. Delivery was such a bonus and went off without a hitch. Would 100% recommend

This was my first time ordering from Onyx Hive, for my dad's 90th birthday. Usually when a cake looks this good, you brace yourself for disappointment. This one exceeded my expectations.
The Triple Chocolate Mousse Cake had the airbrushed finish and glossy shine. There's an option to upload a photo, but there's no point: it looked exactly as advertised. Truly an achievement. The tempered chocolate was top quality. The dark chocolate mousse was perfect: neither too soft nor too firm, and not too sweet. The sponge was moist and light, not heavy or buttery. Everyone at the party raved about it.
Dante makes everything himself, from sourcing to baking to delivery. He confirmed the day before, arrived within his window, and was professional and friendly throughout. I'd order from him again without hesitation.
Mystery cake was so much fun! Such a great experience — I’ve ordered multiple cakes from Dante now, and they’ve been consistently excellent every single time. He really never fails to deliver! Mystery aside, you’ll always get a beautiful cake with great flavour.
