The One Man Business
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!

Bloody yummy! 🍰🍰

The cake was a huge hit! The whole family loved it Dante, thanks so much!!

Very lux design of a cake with flavours to match!

This was such a refreshing cake that we all really enjoyed! Something so different to the usual birthday cakes we get. The fresh lychees were divine , the mousse a perfect consistency and the presentation spot on! I added a small amount of decorations ontop but it didn't need much

Birthday cake for a family member and they loved it. Cake was so pretty with the design and glitter.

My family and I devoured this cake like Bruce in the assembly hall. We expected it to be overly sweet, but it was perfectly balanced. The richness of the chocolate was delicious without being overpowering. The cake was moist, the texture spot-on, and every layer complemented the next. Some of us went full-Bruce and went in for seconds, others resisted their inner Bruce. Overall, highly recommend this cake for the chocolate lovers out there!

The cake was stunning, the matcha and the raspberry mousse was well balanced. Will definitely order again.

First time purchasing and can say I will definitely be purchasing again. The experience as a whole was spot on. The cakebitself is literally an art work and tasted amazing. The mousse is by far the best part so light yet delicious. Ordering was easy and convenient next day delivery. Received a text within minutes of the approx time for delivery which was very much appreciated. The box is as cute as the cake. I honestly couldn't fault anything.

It was soo delicious and light, just the way we wanted. We'll definitely be back for more in the future.
Thanks a ton once again!

Dante created an amazing masterpiece yet again. It was delicious and so unique in every bite, every layer so meticulously fused together. Loved it 🥰

From the start of the order to the finish, it was easy and efficient. Everything I asked for was done to high quality taste. The cake looked out of this world, and it tasted fresh, light and one of the best cakes we had. It was gone in minutes, not stored in the fridge and eventually thrown out like most cakes. Amazing work Dante. You have one huge fan here of your work and everyone that tried it asked where it was from. Can't wait to order again.

10 out of 10 chocolate cake! Not too sweet but sweet enough! Everyone who tried it went back for more. I’ll be definitely getting this cake again. Made with love & care.

This cake looks beautiful and the cake presentation itself was very different from other cakes I've had. More importantly it was so delicious. Everyone in my party said it was one the best cakes they've ever had! I ordered it online 1 day before the party. The process was easy and it was delivered next day. I highly recommend anyone to try this cake and will surely try other flavours on the menu from Onyxhive.

The design of the cake is so unique, everyone complimented on how stunning it looks! The taste was just as amazing - light and fluffy sponge wrapped in a smooth layer of mousse. Highly recommend!

Everyone enjoyed it and it looked incredible too. Will definitely order from Dante again. He’s so friendly and accommodating, just ask your requests and enjoy the cake :)
