It's not the first time that Cadbury have listened to fans and brought back beloved chocolate blocks, but they have done it again with an absolute classic - Marble.

After a petition to bring the chocolate back gained over 20,000 signatures, fans of the milk and white chocolate blend with hazelnut praline were surprised in mid-April by the brand who posted on the fan page to confirm the good news.

"We have been absolutely blown away by the amount of support and love that you have for one of our classic flavours," said the statement.

"Please be assured that every plea, petition and comment has been heard - and we have been working hard to bring back what you want. Although you may have heard whispers already, as a thank you for your passion and commitment, we wanted you to be the first to hear the exciting news.”

The Marble chocolate is set to arrive back on shelves this month, and has been spotted in several stores in New Zealand already. It has been reported that Dairy Milk Marble has been the number one requested bar across the brand's Australian social media channels since it was discontinued.

“Marble fans asked, and we've listened! It's the chocolate Cadbury fans have been demanding we bring back and we're so excited to see it return into people's homes and we wanted to ensure that they heard this great news first," said Cadbury Marketing Manager Katrina Watson said in a statement.
