Twist, lick, dunk. Three simple actions that have defined a snacking ritual for more than a century. On 6 March, kitchens and lunchboxes across the country pay homage to the black-and-white sandwich cookie that has somehow become the best-selling cookie on the planet. National Oreo Cookie Day marks the anniversary of the very first Oreo sold in 1912, and it is a day that needs no persuading — just a glass of cold milk and a stack of your favourite variety.
How to Celebrate National Oreo Cookie Day
From simple indulgence to full-blown baking projects, there are endless ways to honour the Oreo on 6 March.
- Try every variety you can find — Oreo has produced over 85 flavour varieties since the original. Track down limited-edition or regional flavours at your local shop and host a blind taste test with friends or family. From Birthday Cake to Red Velvet, the range may surprise you.
- Perfect the twist-lick-dunk technique — It sounds simple, but there is an art to it. Twist the two wafers apart cleanly, lick the creme filling, then dunk the wafer in cold milk for exactly five seconds — the widely cited optimal dunk time for maximum milk absorption without structural failure.
- Bake an Oreo cheesecake — Crush Oreos for the base, fold chopped Oreos into the cheesecake batter, and top with more crushed Oreos. It is gloriously indulgent and surprisingly easy. No-bake versions work just as well for those who prefer to keep things simple.
- Make Oreo milkshakes or ice cream — Blend Oreos with vanilla ice cream and milk for a thick, creamy milkshake. Or churn your own cookies-and-cream ice cream at home by folding crushed Oreos into a basic vanilla ice cream base.
- Create Oreo truffles — Crush a packet of Oreos, mix with softened cream cheese, roll into balls, and coat in melted chocolate. Chill until set. These three-ingredient truffles are one of the simplest and most addictive treats you can make.
- Challenge yourself to an Oreo stack — How many Oreos can you stack before the tower topples? Competitive Oreo stacking has become a social media staple. Film your attempt and share it online.
- Learn the history — Read up on how the Oreo went from a single product sold to a grocer in Hoboken, New Jersey, to the world’s most popular cookie. The journey involves corporate mergers, flavour experiments, and some genuinely clever marketing.
- Share the love — Buy extra packets and share them with colleagues, neighbours, or a local community group. Few things break the ice quite like offering someone an Oreo. If you enjoy celebrating food-themed days, you might also appreciate National Cereal Day on 7 March, another nostalgic favourite.

The History of National Oreo Cookie Day
The Oreo’s story begins on 6 March 1912, when the National Biscuit Company (Nabisco) first sold the cookie to a grocer in Hoboken, New Jersey. Originally called the “Oreo Biscuit,” the cookie was designed as a competitor to the Hydrox cookie, which had been on the market since 1908. While Hydrox came first, Oreo’s superior marketing and slightly sweeter creme filling gradually won over consumers, and Hydrox eventually faded into obscurity.
The name “Oreo” has been the subject of much debate. Some suggest it derives from the French word “or” (gold), reflecting the colour of early packaging. Others point to the Greek word “oreo” meaning beautiful or nice. Nabisco has never confirmed the official origin. The cookie’s design has also evolved — the current embossed pattern on the wafer, featuring a cross with a two-bar design surrounded by a wreath of laurels and dashes, was introduced in 1952 and was reportedly designed by William Turnier, a Nabisco engineer.
Over the decades, Oreo expanded from a single product to a global brand. In 2024, Oreo generated over $4 billion in annual revenue worldwide. The cookie is now sold in more than 100 countries and has been adapted for local tastes — green tea Oreos in China, dulce de leche in Argentina, and blueberry ice cream in Indonesia, to name a few. National Oreo Cookie Day formalised the anniversary celebration, gaining mainstream recognition through social media and Nabisco’s own marketing efforts in the 2010s.
