If you’ve navigated the snack aisles of an American Costco recently, you might have noticed a sudden, inexplicable gap where a pallet of chocolate cookies used to be. You are witnessing the fallout of a structural snack deficit finally being resolved. Australia’s legendary Arnott’s Tim Tam biscuits have officially landed in U.S. Costcos in massive bulk boxes — and shoppers are treating them like gold dust.
But why is an imported chocolate biscuit causing a nationwide frenzy? Here is a deep dive into the anatomy of the Tim Tam, the legendary ritual of the “Slam,” and the slight ingredient controversy brewing among purists.
What Actually is a Tim Tam?
Introduced in 1964 by Ian Norris of Arnott’s Biscuits, the Tim Tam was allegedly inspired by the British “Penguin” biscuit, with Norris vowing to “make a better one” after a trip to Britain. Named after the winning horse of the 1958 Kentucky Derby, the Tim Tam is an architectural marvel of the snack world.
It consists of two crumbly, malted biscuits separated by a light, aerated chocolate cream filling, all completely enrobed in a thin layer of textured chocolate. It is estimated that Arnott’s Huntingwood bakery in Western Sydney churns out around 3,000 Tim Tams per minute just to keep up with global demand, using 27 tons of chocolate coating each workday.
The Costco Haul
For years, American fans of the biscuit had to rely on international grocery aisles, paying a premium (often $5 or more) for a single sleeve. Costco has obliterated that market with Item #1967992.
The warehouse club is selling a heavy-duty box containing six 7-ounce sleeves (a whopping 66 cookies in total). Retailing between $13.89 and $14.99 — though some lucky bargain hunters have spotted clearance prices as low as $6.97 — it’s an exceptional value. On Reddit’s r/Costco, users are openly admitting to their lack of self-control, with one user describing the snack as “dangerously addictive” and another confessing to finishing the 66-cookie box in under a week.
The Legend of the “Tim Tam Slam”
You cannot talk about Tim Tams without discussing the ritualistic way they are consumed. In Australia, it’s a cultural touchstone known as the “Tim Tam Slam.” Because of the cookie’s unique matrix, it can be temporarily transformed into a piece of edible kitchenware.
Here is the exact methodology:
- The Prep: Bite off two opposite, diagonal corners of the rectangular biscuit.
- The Draw: Submerge one bitten corner into a hot beverage (coffee, milky black tea, or hot chocolate) and use the cookie as a straw to suck the hot liquid upward.
- The Slam: As the hot liquid travels through the biscuit, the inner chocolate cream matrix melts into a molten, gooey fudge state. Before the cookie’s structural integrity collapses completely into your drink, you “slam” the entire thing into your mouth.
The result is an instant mocha-fudge explosion that completely ruins standard dunking for the rest of your life.
The Ingredient Controversy: Is it the “Real” Thing?
As with any international product scaled for the American market, the Costco arrival hasn’t been without a bit of internet sleuthing and skepticism.
While the box proudly states “Australia’s Favorite Cookie,” purists on Reddit and food journalists at The Takeout noticed a catch in the fine print. The U.S. Costco version contains artificial color additives — specifically Red 40, Yellow 6, and Blue 1. While these dyes aren’t strictly banned in Australia, they are not typically listed on the domestic Australian ingredient labels for Tim Tams, leading some fans to point out the differences in food regulation. Additionally, some Australian expats note that the American packaging lists generic “chocolate” in the ingredients, whereas the Australian version prominently features “milk chocolate” near the top.
The Verdict
Despite the minor ingredient tweaks for the U.S. market, the consensus is overwhelming: Costco’s bulk Tim Tams are a triumph. Whether you’re an Aussie expat desperate for a taste of home, or an American looking to upgrade your morning coffee routine with a Tim Tam Slam, this is a pallet worth hunting down. Just be warned — once you open a sleeve, moderation goes out the window.
