Smashing open cakes filled with lollies and gifts was once the domain for kids' parties, but now adults are joining in on the fun.
For Clare O'Rourke, 36, from North Sydney, a boob-shaped Smash Cake signified the end of a significant stage in her breast cancer treatment.
She wanted to do something to thank the team at the Royal North Shore Hospital (RNSH) who were her pillars of strength.
"The cancer was pretty large (Stage 3+), but I have a great medical team (oncologists, surgeons, nurses, physios and more) that commenced my treatment very quickly," Ms O'Rourke said.
"It was an absolute whirlwind - I undertook intense chemotherapy followed-up with surgery and radiotherapy which finished in late March.
"I am now starting the next stage of treatment which is hormone therapy and possibly a clinical trial."
Having no family history and being under the age of 40, she was shocked when she was diagnosed.
"The hardest part was telling family and friends," she said.
"There is a lot of uncertainty to deal with, along with fear of the unknown - the uncertainty of cancer, the uncertainty of work and money, the uncertainty of side effects but once you start treatment and you know you're on a path, they start to ease.
"There are so many process improvements required to make the treatment journey a better experience for the patient, but my radiotherapy team made it bearable (and at times nearly enjoyable) by always turning up with a smile, having a laugh and often going above and beyond to ensure I was cared for."
She still has further treatment ahead, but was keen to send a message of thanks to the medical staff at the RNSH who helped support her and bring a smile to her face.
"Healthcare workers don't get enough recognition for the work they do and I really wanted to acknowledge the team for their hard and relentless work," she said.
"There is so much doom and gloom with cancer and what better way to lighten the day with a boob cake - blunt, simple and somewhat elegant - and lollies are always good fun.
"Cancer needs to be smashed and what better way than with a piñata style Smash Cake – it was a great way to say thanks whilst having some fun, smashing out any frustrations and celebrating the wins."
What I love so much about my job is that every SmashCake I create, has a story. Whether it’s a birthday, gender reveal, wedding or anything and everything in between. But this particular story is special and inspiring so I wanted to share it with you. Last year I had a client who ordered a donut SmashCake for her PT. Her cheeky sense of humour was evident in her choice of SmashCake. A couple of weeks ago she contacted me again for another SmashCake. This time she wanted a pair of boobs. It turns out she has just finished her treatment for breast cancer and wanted to give the doctors and staff at the hospital a cheeky thank you gift. It is so inspiring to know that even though she has been through hell and back, she has stayed strong and kept her sense of humour. Clare you are amazing!! 💖👊💪 ・ ・ ・ ・ #sydneysmashcakes #breastcancer #fuckcancer #breastcancerawareness #staystrong #yougotthis #sobrave
Founder of Sydney Smash Cakes Claudia Abrahams, who supplied the boob Smash Cake, first discovered the concept in an Australian Women's Weekly cookbook.
"I began creating them for my children's birthday parties which led to requests from other parents to do the same for them, resulting in the creation of my own business three years ago," Ms Abrahams said.
"Surprisingly, adults are now using Smash Cakes to create memorable experiences and it's no longer considered something only children will enjoy.
"Adults are loving the fun, interactive experience they have when smashing our cakes - it is something different and fun – and it is also an empowering experience for those having a tough time."
She sells Smash Cake Easter eggs, ones filled with edible slime, pink and blue ones for gender reveals and a whole host of other options for kids, adults and corporate clients, as well as DIY kits for parents to make with their children.
"People are using food to cherish life moments and there is no limit to their creativity," she said.
Hairdresser Isabella Russo, from Sydney, wanted to do something supportive for her 14-year-old client Tammy who was diagnosed with Hodgkins lymphoma earlier this year.
"I was going to send flowers, but they are not allowed in the cancer wards at hospital because of the chance of bacteria and triggering allergies," Ms Russo said.
Instead, she took her a Smash Cake with the words Team Tammy on it.

"Tammy took great delight in smashing the cake open and was delighted when all the lollies spilled out," she said.
"It lifted the energy in the hospital room and we were all cheering Tammy on as she smashed the cake - like she is going to smash cancer.
"Tammy is a brave young lady. She has lost all her hair because of the chemotherapy and is still receiving treatment, but is determined to win this cancer battle."
