Cadbury's Dairy Milk Neapolitan won't be available in Ireland.
The bar is one of the most popular in Australia.
Shoppers in Ireland have struggled to get their hands on the chocolate bars without having to pay an extortionate shipping fee.
A spokeswoman for the company told the Irish Mirror: "Cadbury Dairy Milk Neapolitan is a Cadbury product enjoyed in other countries around the world.
"At the moment Cadbury Dairy Milk Neapolitan is not available in the UK or Ireland, but it sounds like Cadbury fans wish it was."
Now B&M has revealed it's selling one of Australia's most popular bars in its UK stores.
A picture of the new bar was shared on Instagram by @kevssnackreview, who posted: "Dairy Milk Neapolitan is now in @bm_stores! Plus Choc Orange Shreddies are back."
The picture instantly attracted attention, with many people saying they're keen to try it.
Preema_r tagged a friend and said: "Get me one."
Chloestead_ also tagged someone saying: "Get me a bar today please."
Abbie.r0ad added: "This chocolate looks so nice."
Matthew Bell said: "I want this."
Kirstie Duguid added: "I want now."
Mandy Jane Cook said: "A trip to b n m is needed!!! This looks amazing."
And Trudy Fearn added: "I dunno. I think I could go for it!"
Cadbury says, "Cadbury Dairy Milk Neapolitan is a nostalgic nod to a favourite Australian dessert and a novel take on the ice-cream classic that delivers a unique 3 layered block."
The Cadbury Neapolitan bar is not yet listed on the B&M website, but similar-sized Cadbury bars including Crispy Mint Creme, Cadbury Caramilk, Cadbury Marble and Dairy Milk Top Deck are available online and in selected stores.
The Cadbury Neapolitan bars are also available on GB Gifts.
