About Sir Sour
Sir Sour is a boutique custom cake studio based in Coburg, Melbourne, creating beautifully designed, made-to-order cakes since 2018. Isabella, the face and creative force behind Sir Sour, first established the brand as a passion-driven cake studio, inspired by a love for baking and thoughtfully designed desserts.
We specialise in crafting custom cakes that reflect your style, your story, and the moments worth celebrating. From elegant wedding cakes and refined dessert creations to fully customised designs for birthdays and special occasions, every cake is thoughtfully designed and freshly baked using premium ingredients.
At Sir Sour, baking is more than just what we do: it’s what drives us. We work closely with our clients to bring ideas to life, creating cakes that feel personal, memorable, and truly unique. No two celebrations are the same, and neither are our cakes.
Whether you’re planning a wedding, celebrating a milestone, or marking a meaningful moment, we’re here to create something beautiful, delicious, and unforgettable.

Sweets Crafted for Your Moment
Cake isn’t just dessert, it’s the memory everyone gathers around.
And when it’s hand-made, custom, and baked to order, the moment feels even more special.
At Sir Sour, we design cakes that tell your story: playful colours for kids’ parties, sculpted statement cakes for big milestones, romantic finishes for weddings, luxe textures for corporate events, and personalised touches for every beautiful celebration in between.
No matter your style, whether it is minimalist, whimsical, elegant, dramatic, colourful, tall cake, or sculpted cake, our job is to bring your vision to life with flavour, creativity, and that “wow” factor.
