About National Chocolate Milkshake Day
National Chocolate Milkshake Day falls on Saturday, 12 September 2026. This American food holiday celebrates one of the most beloved cold drinks ever poured: a thick, frosty blend of chocolate, milk and ice cream. It is a day for milkshake lovers to pull out the blender, visit a favourite diner or soda fountain, and raise a frosty glass to a treat that has delighted people for well over a century.
How to Celebrate National Chocolate Milkshake Day
The best way to mark the occasion is simple: drink a chocolate milkshake. Here are eight ways to make the most of the day.
- Blend your own at home – Combine two generous scoops of vanilla or chocolate ice cream, a splash of cold milk and a few spoonfuls of chocolate syrup, then blend until thick and frothy. Adjust the milk for your preferred consistency.
- Visit a classic diner or soda fountain – Few things beat a hand-spun shake served in a tall glass with the metal mixing tin on the side. Seek out a retro diner and order the real thing.
- Host a milkshake bar – Set out toppings such as whipped cream, sprinkles, crushed biscuits, marshmallows and a cherry, and let friends and family build their own creations.
- Experiment with flavours – Add a spoonful of peanut butter, a shot of espresso, a handful of berries or a pinch of sea salt to give your chocolate shake a twist.
- Make it a malt – Stir in malted milk powder for an old-fashioned chocolate malt, the drink that made milkshakes famous in the 1920s.
- Go dairy-free – Swap in oat, almond or coconut ice cream and plant milk so everyone can join in, whatever their diet.
- Share it on social media – Photograph your most outrageous shake and post it with the day’s hashtags to inspire others to take part.
- Treat someone else – Surprise a colleague, neighbour or family member with a chocolate milkshake. It is a small gesture that turns an ordinary day into a celebration.
What is National Chocolate Milkshake Day?
National Chocolate Milkshake Day is an unofficial American food holiday dedicated to the chocolate milkshake. It is one of dozens of food days observed across the United States each year, and like many of them it has no single organising body. The day is for anyone who enjoys a cold, creamy, chocolatey drink, from children grabbing a treat after school to adults reliving the nostalgia of the classic soda fountain. If you have a soft spot for sweet, frozen treats, you might also enjoy National Ice Cream Soda Day, another celebration with deep roots in the American soda fountain.
When is National Chocolate Milkshake Day?
National Chocolate Milkshake Day is observed every year on 12 September. In 2026 that falls on a Saturday, making it a perfect weekend excuse to indulge. The date is fixed and does not change from year to year, so you can count on 12 September for chocolate milkshakes annually.
The History of the Chocolate Milkshake
The word “milkshake” first appeared in print in 1885, though the early version bore little resemblance to today’s treat. It described a sturdy, eggnog-style drink made with eggs, whiskey and other ingredients, marketed more as a health tonic for adults than a sweet for children. Over the following years the recipe softened. By around 1900, pharmacies and soda fountains were serving wholesome milkshakes flavoured with chocolate, strawberry or vanilla syrup.
The drink took its modern form in the early twentieth century once ice cream entered the mix. A major turning point came with the electric blender. In 1922 Stephen Poplawski patented a spindle blender designed for soda fountains, and that same year a Walgreens employee in Chicago named Ivar “Pop” Coulson added two scoops of vanilla ice cream to the standard malted milk drink. The result, a thick and frothy malted milkshake, became a sensation. Within a year Walgreens stores across the country were selling their double-rich chocolate malt, and the milkshake as we know it was born.
The origins of the awareness day itself are far less documented. No single founder is credited with creating National Chocolate Milkshake Day, which is common among American food holidays. References to the day on 12 September appear in newspapers from at least the mid-1990s, and it has since become a fixture of the annual food calendar, embraced by diners, dairy brands and milkshake fans alike.
Fun Facts About Chocolate Milkshakes
- The term “milkshake” originally referred to an alcoholic drink containing whiskey and eggs, not the sweet treat we know today.
- The modern milkshake owes its frothy texture to the electric blender, patented for soda fountains in 1922.
- A “malt” or “malted” is a milkshake with malted milk powder added, the style that first made the drink a soda-fountain star.
- In parts of New England, a milkshake made with ice cream is called a “frappe”, while “milkshake” can mean simply flavoured milk.
- Chocolate consistently ranks among the most popular milkshake flavours, alongside vanilla and strawberry.
- The soda fountains that popularised milkshakes became important social gathering spots for young people in the early twentieth century.
Why National Chocolate Milkshake Day Matters
Beyond the simple pleasure of a sweet drink, the day celebrates a genuine piece of American culinary heritage. The milkshake is tied to the rise of the soda fountain, the invention of the blender and decades of diner culture. Marking the day keeps that history alive, supports the independent cafes and ice cream parlours that still hand-spin shakes, and gives families an easy, joyful reason to gather around a treat that crosses generations.
