Australian chocolate lovers are rushing to buy Cadbury Caramilk – the 1990s treat making a temporary comeback – with consumers willing to spend more than $100 on eBay to stock up.

The golden blend of caramelised white chocolate has returned to Australian supermarket shelves due to popular demand as a limited edition, more than 20 years after it was discontinued in 1994.

Mid last year when Caramilk reappeared in New Zealand, the million bars sold in just three weeks, with some Kiwis buying blocks for $5 from supermarkets and selling them for more than six times the price on eBay.

Now a similar craze is being seen in Australia, since the bars re-emerged last week, as consumers rush to get their hands on the nostalgic chocolate block.

In one example, a seller priced seven blocks for $150 – about $21 each, more than eight times the retail price at supermarkets including Coles and Woolworths.

And it’s no surprise, given Australian Caramilk fans have created a Facebook page and Change.org petition dedicated to bringing back the retro chocolate.

The petition’s founder, Trent O’Toole, described how jealous he was to discover Cadbury New Zealand had announced a product reboot.

“After a night crying in my sleep as I lay in a foetal position, I woke up with a new-found purpose,” Mr O’Toole said.

“It’s time for Cadbury Australia to sit up and take notice.

“Cadbury New Zealand listened and now we need to make Cadbury Australia listen too.”

Cadbury’s Paul Chatfield, associate director of Everyday Chocolate, said the product was “flying off the shelves” even in its first few days after being re-introduced to Australian stores.

He said the product’s return was solely prompted by customer demand.

“Given the demand from Aussie consumers, we’ve now brought a limited quantity to Australian retailers and feedback from the first stores to have the block on shelf is that they’re disappearing fast,” Mr Chatfield said.

“Often people have a very positive, nostalgic view of a heritage product and … when we bring back an old favourite we need to ensure we’re delivering a taste experience that matches people’s recollection of the product.

“There are currently no plans to bring Cadbury Caramilk back as a permanent product in our blocks range.”

Woolworths told The New Daily it “jumped at the chance” to stock the old-time chocolate favourite after seeing the response to the New Zealand relaunch.

“It has been extremely popular and we’re pleased many customers have been able to enjoy this limited-edition favourite,” a spokesman said.

Coles was contacted for comment.
