National Vanilla Milkshake Day is celebrated every year on June 20, giving milkshake lovers a fixed date to enjoy the creamy, nostalgic blend of vanilla ice cream, cold milk, and a splash of vanilla flavoring. It is one of many food-themed observances on the American calendar, and it spotlights a drink that has been a soda-fountain staple for more than a century.
When is National Vanilla Milkshake Day?
National Vanilla Milkshake Day is a fixed observance held on June 20, meaning it lands on the same calendar date every year rather than floating to a particular weekday. In 2026 it falls on Saturday, June 20, which makes it a convenient weekend excuse to visit an ice-cream parlor. Because the date never shifts, you can plan for it the same way each year.
History and origin of National Vanilla Milkshake Day
The observance’s own beginnings are not well documented. National Day Calendar, one of the most widely cited registries of these days, notes that it is still researching the origins of the celebration, and no individual founder or sponsoring organization is publicly credited. In short, who created National Vanilla Milkshake Day, and when, is genuinely unknown.
The milkshake itself, however, has a clearer story. The term “milk shake” appeared in print as far back as 1885, when it referred to a very different drink that could include eggs and even whiskey as a kind of tonic. By the early 1900s, soda fountains had reworked the idea into wholesome, kid-friendly milk-and-flavor drinks. The modern ice-cream milkshake is widely credited to Ivar “Pop” Coulson, a Walgreens soda-fountain worker who, around 1922, added scoops of vanilla ice cream to malted milk. The rise of electric drink mixers around the same era made blending thick, frothy shakes fast and consistent, cementing the vanilla milkshake as an American favorite. As soda fountains multiplied through the mid-twentieth century, the vanilla shake became a default order and a canvas for endless variations, from malted versions to fruit-and-candy add-ins that would later inspire modern shake menus.
Why National Vanilla Milkshake Day matters
Vanilla is often treated as the plain option, but on this day it takes center stage. Vanilla is one of the world’s most labor-intensive spices to produce, and a well-made vanilla shake shows off the flavor rather than hiding it. The day is also about nostalgia: milkshakes evoke classic diners, drive-ins, and soda fountains, and they remain a low-cost, shareable treat that spans generations. For small ice-cream shops and diners, the observance is a friendly marketing moment that draws in customers during early summer.

Fun facts
Vanilla is the second most expensive spice in the world after saffron, largely because vanilla orchids must often be pollinated by hand. Despite that, vanilla remains one of the most requested ice-cream and milkshake flavors worldwide. The classic soda-fountain milkshake also helped popularize the electric blender in American kitchens, turning a niche appliance into a household staple. Vanilla itself comes from the seed pods of a climbing orchid, and true vanilla flavor is prized enough that most of the world’s supply is grown in just a handful of tropical regions. That rarity is exactly why National Vanilla Milkshake Day is worth marking: it treats a flavor often dismissed as “basic” as the star ingredient it deserves to be.
