In short:
The UK’s rival version of a Tim Tam, the Penguin, is now labelled as “chocolate flavour” because it no longer meets the UK’s definition of chocolate.
Rising cocoa prices have led to some manufacturers changing the recipes of chocolate products to the point they can no longer be legally defined as chocolate.
What’s next?
Tim Tam maker Arnott’s says it has no plans to change its recipe. Cocoa commodity prices are starting to fall but retail chocolate prices are expected to remain high for some time.



You can find them at World Market, but like most of the food at World Market, it’s overpriced. Some Target and Walmart stores have Tim Tams, or at least the ones where I am in Northern California. There’s a Fijian grocery store near me that has a bunch of Aussie things too.
My wife and I usually just bring some back with us when we visit Australia. We’re both Australian so we try to go back every so often to see friends and family.
