It's the meeting of two great food empires. Cadbury and Oreo have teamed up on a few products now but this one is especially good.
You can now buy Oreo cakes, covered in a layer of Cadbury's chocolate, for £2 at B&M.
The only thing that would be better than this is if Nando's teamed up with Domino's to make a peri chicken pizza (do we have enough influence to make this happen? Hope so).
The cakes are apparently really rare, with some of them being sold on eBay for £6.50 - that's more than three times the price of B&M
The bargain store is selling them in big boxes, with 12 cakes in each box.
What you're essentially looking at here is a cake bar, a bit like a mini roll, with dark chocolate cake, creamy frosting as a filling, and a layer of Cadbury's chocolate round the outside.
Wonder if it gets all up in your teeth like Oreo biscuits do.
B&M have said that customers are clearing the shelves of them already - can't blame them really, this sounds epic.
It works out to just 17p per cake bar.
The product launched in stores last week and already they're popping up on eBay.
Users are apparently describing it as a 'party in your mouth'.
We found a video on YouTube of someone actually cutting into one, and they look pleasantly solid - more like a brownie than a crumbly cake.
If you fail to get your hands on them, you'll have to make do with other Cadbury/Oreo collabs.
Their signature big bars come with a creamy Oreo filling sometimes, which is always a bloody treat (I always put mine in the fridge, which is controversial). They also do a big bar with a peanut butter Oreo filling and a mint flavoured one too.
The new Big Taste range basically had entire Oreos squished into a massive bar of Cadbury's. 'Mazing.
B&M is one of those shops that basically sells a bit of everything - paddling pools, mirrors, multipacks of cherry Coke, mops, weird flavours of Monster Munch - and once people catch wind of a good thing, like the Oreo cakes, they tend to fly out.
If you want in, you'd better get a wriggle on. Or just pay the eBay prices.
