Tim Tams are beloved by both Kiwis and Aussies, but trade moves across the ditch could see the yummy treat being sold in the UK - with the British version of the iconic snack being sold in Australia.
The two biscuits are actually strikingly similar, both consisting of two choccie biscuits sandwiched together with a chocolate cream and coated in more chocolate.
But which one reigns supreme?
If you ask any British ex-pats, they'll tell you a Penguin of course. But Kiwis will defend the iconic Tim Tam to the end.
Mark Schomberg, the development chef at beloved British biscuit maker McVitie's, says the difference between the two can be found in the crunch.
"The key difference is the crunch factor – Penguins have a great bite to them," Shomberg told news.com.au.
"They audibly crack when they hit your teeth, whilst still having that delicious chocolate coating, double biscuit layering and chocolate cream filling."
Since Johnson declared, "I want to live in a world where we send you Penguins" in June, Twitter has erupted in debate between the two nations over the superior sweet treat.
Aussies described Penguins as the lesser version of the transtasman favourite.
Just eaten a Tim Tam, a superior version of a Penguin. This is chocolate and not bird related.

Whaaaatt?? They are a single colour - chocolate! How do you get penguins from that?! #TimTams
Others branded the Penguin a "fake Tim Tam" while another said it would "send those Penguins right back to the UK".
It's a sentiment long echoed on by the two Aussies behind the blog, Sorry Dad, England is Weird, who claim Penguins are the no frills version of Tim Tams.
"Tim Tams taste better. They're rich, decadent and smooth," the post, dated 2009, states.
However, the Brits – who invented the Penguin 31 years before the Tim Tam ever existed – say it is by far the best.
Chocolate isn’t as good on a tim tam. The plus side is theyre not individually wrapped so you can eat a while pack and not feel bad. Whereas unwrapping a multipack of penguins feels like pure gluttony!
"We've noticed some rather questionable and lurid tea-drinking performances from our Southern cousins, where we would just dip and sip, in an act called the Penguin Dip."
In case you've been living under a rock, a Tim Tam slam works by biting the opposite corners off a Tim Tam, dipping it into your drink of choice, and then sucking the liquid through the biscuit.
