Melba Elite Foods sells its high-quality goods to businesses but products with cosmetic issues such as oddly-shaped, off-centre fillings and wonky slices, cannot be sold.
Despite the visual imperfections the taste and quality are intact and the company usually sells the goods to staff at hugely-discounted prices.
National operations manager Kevin Sox said this year the staff decided they could all give back.
"Especially in times like this as we're going into school holidays and Christmas, we prefer to give out the samples to the likes of foodbank."
Sox said without the imperfections, the desserts would cost businesses between $15 and $18 meaning 300 of them were valued at $5400.
The company has been donating its goods for at least eight years.
Sox said he was unaware until recently these sorts of treats were only available for foodbank clients through donations.
For people who received parcels from the foodbank to be able to still get an unexpected treat was heartwarming, he said.
Foodbank manager Nicki Goodwin said sweet treats weren't in its budget and were only available for clients if donated.
"We love putting them in parcels.
"It's unexpected to get a beautiful cake or slice in your food parcel ... it's just happiness."
When they do get sweet treats, volunteers put them at the top of the parcel so it is the first thing seen when opened.
As the foodbank has extremely limited storage, Sox said Melba Elite Foods would store the goods for the foodbank so it can collect as needed.
"That is so, so helpful," Goodwin said.
