Costco Customers Hoard Australian Tim Tam Cookies in Nationwide Shopping Frenzy

Legendary Australian Biscuit Lands at Costco Warehouses

Costco shoppers are flocking to warehouse aisles across the United States to stock up on Tim Tams, the iconic Australian chocolate biscuits that have sparked a nationwide buying frenzy. The cookies, nicknamed the “Australian Oreo,” have generated massive attention on social media since arriving at Costco locations. American consumers who were previously unfamiliar with the legendary snack are now hoarding multiple cases in their shopping carts. The warehouse retailer stocks Tim Tams in six-sleeve boxes containing 66 cookies for approximately $13.99. This gives Americans broader access to a snack that was previously available primarily through specialty retailers and international food stores.

Reddit users report purchasing between five to nine cases at once. This creates aisles full of shoppers hoarding the chocolate treats. One enthusiastic customer purchased multiple cases and defended the bulk buy online. Another shopper declared them worthy of absolute loyalty, calling the cookies the best store-bought option available anywhere. The passion for these Australian biscuits reaches extreme levels in online communities dedicated to discussing the product. Social media platforms overflow with photos of stocked Costco shelves and customer testimonials praising the chocolate-covered treats.

What Makes Tim Tams Different From Traditional Cookies

The Original Tim Tam features two malted chocolate biscuits layered with a creamy cocoa filling and coated in textured chocolate. This creates a triple-layered construction that sets it apart from standard American cookies. Arnott’s, the Australian food giant, created these biscuits in 1964. The brand has been a national treasure in Australia ever since. While Americans currently find mainly the classic chocolate version at Costco, the brand offers numerous varieties internationally. These include White Chocolate, Mangoes and Cream, and Chocolate Mint flavors that Australian consumers enjoy regularly.

A premium line called Tim Tam Deluxe exists in Australia featuring a heavier chocolate coating and an ooey-gooey center filling. The deluxe flavors include Salted Caramel Brownie with an explosion of salted caramel and Decadent Triple Chocolate featuring silky dark chocolate cream. The cookies being sold in American Costco warehouses differ slightly from the Australian original. The U.S. boxes list ingredients including artificial color additives such as Red 40, Yellow 6, and Blue 1. These additives do not appear on ingredient lists for Tim Tams sold in Australia. Despite these modifications, American shoppers continue to embrace the cookies with remarkable enthusiasm.

The Tim Tam Slam Ritual Goes Viral in America

The love for Tim Tams extends beyond simple taste preferences. American customers are quickly learning about the ritual that has made these cookies a cultural icon down under. The “Tim Tam Slam” involves biting off diagonal corners of the biscuit. Consumers then submerge one end in a hot beverage. Next, they suck the liquid through the cookie like a straw. Once hot coffee or tea melts the inner cream filling, consumers eat the softened cookie. Timing matters because the biscuit must be consumed before it dissolves completely into the beverage.

“My Australian friend said to drink your coffee through them like a straw,” one Reddit user raved about discovering the technique.

TikTok videos showcasing “Aussie culture” have driven massive visibility for the technique with tutorials on how to properly execute a Slam. The theatrical nature makes it perfect for social media content, where visual demonstrations drive engagement and encourage viewers to try the experience themselves. Celebrity endorsements have amplified awareness even further. Australian actress Isla Fisher recently gave television host Kelly Clarkson a masterclass on the technique during an appearance on The Kelly Clarkson Show. Sarah Snook, the Australian actress known for her role in the hit series Succession, demonstrated the ritual to Jimmy Fallon on The Tonight Show. The two dipped their Tim Tams in tea for the live studio audience.

International Food Brands Find New American Audiences

The viral appeal has helped Tim Tams transcend their status as merely another imported snack. The cookies represent a broader trend of international food brands finding enthusiastic new audiences in the United States. Social media platforms introduce American consumers to products and traditions that remain unfamiliar outside their countries of origin. This digital word-of-mouth marketing proves extraordinarily effective at building demand for specialty items. Costco has recognized this opportunity and responded by expanding its international product offerings. The retailer understands that members seek exclusive items they cannot find at traditional grocery stores or competing warehouse clubs.

Costco uses exclusive items, limited-time offerings, and its Kirkland Signature private-label brand to differentiate itself from competitors. The Tim Tam launch reflects this strategic approach to merchandising. The warehouse giant imports these particular cookies directly from Sydney. Consumers appreciate access to authentic international products rather than domestically produced imitations. The enthusiasm surrounding Tim Tams demonstrates that American shoppers will embrace foreign snacks when given proper introduction to their cultural significance and unique consumption rituals.

Why Bulk Buyers Cannot Get Enough Tim Tams

The six-pack format at Costco contains 11 cookies per sleeve, creating a total of 66 biscuits per case. Even this substantial quantity fails to satisfy the most devoted fans. Online forums feature discussions about optimal storage methods for bulk purchases. Some customers express concern about running out between Costco shopping trips. Others debate whether the cookies taste better when consumed immediately or after aging slightly in the pantry. The passionate online communities demonstrate that Tim Tams have achieved more than simple product awareness. They have created a dedicated American fan base willing to invest significant money and pantry space into stockpiling the treats.

One Reddit user offered advice to Australian travelers planning trips to the United States. The suggestion recommended bringing a second suitcase to carry back as many Tim Tam varieties as possible from Australian stores. This reverse importation underscores how the limited American selection leaves fans craving the full range of flavors available in the cookies’ home market. The demand suggests potential for Arnott’s and Costco to expand the product line in future shipments. American consumers have proven their willingness to embrace Australian food culture when given the opportunity to participate in authentic traditions like the Tim Tam Slam.
