Invention of the Milkshake

You might be surprised that the first milkshake wasn’t a dessert at all. In the late 1800s, you’d have gotten a whiskey-and-egg drink, more like eggnog than ice cream. By 1900, it shifted into a nonalcoholic soda-fountain treat with milk, syrup, and crushed ice. Blenders, malted milk, and vanilla ice cream transformed it in the 1920s, and Walgreens helped popularize the creamy version you know today. Stick around, and the story gets even richer.

Key Takeaways

• The first printed “milkshake” in 1885 described an alcoholic whiskey-and-egg drink, not the ice-cream dessert drink we know today.
• Early milkshakes were hand-shaken with milk, syrup, crushed ice, or malted milk, and often contained no ice cream at all.
• Prohibition and 1920s blender adoption helped transform milkshakes into smooth, nonalcoholic, family-friendly treats across America.
• In 1922, Walgreens soda jerk Ivar “Pop” Coulson popularized a modern-style malted shake with vanilla ice cream, milk, chocolate syrup, and Horlick’s malt.
• New machines, from Hamilton Beach mixers to Poplawski’s 1922 blender, made milkshakes thicker, fluffier, faster, and easier to standardize.

What Was the First Milkshake?

Surprisingly, the first milkshake wasn't the sweet ice-cream drink you'd expect today. When you look at the term's origin, you find the first printed mention in 1885. Back then, a milkshake meant an alcoholic drink, closer to a whiskey eggnog than a dessert. You'd get cream, eggs, and whiskey mixed into a rich tonic treat that people considered both sturdy and healthful. The name itself came from the shaking method used to mix drinks in tumblers, jars, or early patented shakers.

As you move toward 1900, you see the meaning change. Milkshakes started becoming wholesome hand-shaken drinks made with crushed ice, milk, sugar, and flavorings. Soda fountains and home servers added chocolate, strawberry, or vanilla syrups, shaping the sweeter version you'd recognize. In 1922, adding vanilla ice cream marked a major turning point that helped create the modern milkshake. Around this same era, frozen treats were gaining popularity across America, including the Popsicle patent of 1923, which reflected a broader public appetite for affordable and portable sweet refreshments. So, the first milkshake began as a hearty mixed drink before it turned into a familiar flavored refreshment for many Americans.

How Did Milkshakes Start as Alcoholic Drinks?

If you trace the name back to 1885, you find that milkshakes started out as adult drinks, not ice-cream desserts. Their alcoholic origins show up in newspaper descriptions of a sturdy, eggnog-style mixture made with whiskey, eggs, milk, sugar, and ice. You'd order one as a five-cent novelty and get something closer to a cocktail than a diner treat. The first recorded use of the term actually appeared in 1855, describing an eggnog-style drink with whiskey rather than the dessert people know today.

Bartenders and soda-fountain workers shook the ingredients by hand in tumblers, jars, or tin cans, much like lemonade. They might add flavored syrup, crushed ice, and even nutmeg on top. Early references, including the Atlanta Constitution in 1886, framed the drink through tonic marketing, so you saw it promoted as both healthful and indulgent. In that form, the milkshake belonged to adults who wanted refreshment with a spirited kick. By the early 1900s, the drink's meaning began shifting toward non-alcoholic versions made with milk and flavored syrups. Much like the teabag, which was accidentally invented in 1908 by New York tea importer Thomas Sullivan, some of the most enduring drink traditions in history began through unintended discoveries rather than deliberate design.

When Did Milkshakes Become Non-Alcoholic?

By the early 1900s, milkshakes had already begun shedding their alcoholic identity as soda fountains swapped whiskey for chocolate, strawberry, and vanilla syrups. If you trace the name back to 1885, you'll find an egg-and-cream whiskey drink, but by 1900, you'd more likely order a sweet, family-friendly treat instead. In New England, these alcohol-free versions were often called frappes rather than milkshakes.

The biggest push came from Prohibition effects after 1920, when U.S. stores stopped adding alcohol and promoted milkshakes as safe alternatives for children and adults. Blender adoption also changed everything. Soda fountains first used mixers like the 1911 Hamilton Beach Cyclone, then newer electric blenders in 1922 made shakes smoother and frothier. As drugstores and diners embraced these alcohol-free drinks through the 1920s and 1930s, you'd recognize the modern milkshake taking shape for everyday American life. By the early 1900s, many versions were already being served with ice cream, helping define the modern milkshake as a dessert drink. This shift away from alcohol mirrors the evolution of other drinks of the era, such as the French 75 cocktail, where effervescence of sparkling wine was noted for speeding up alcohol absorption, a property that made high-alcohol drinks increasingly scrutinized during the temperance movement.

Why Did Malted Milk Change Milkshakes?

As milkshakes spread through soda fountains, malted milk changed them because it fixed both flavor and texture at once. You can see the malted chemistry in how dried malt blended with powdered milk and sugar, solving viscosity problems while making shakes sweeter, richer, and more stable. That practical boost came from the Horlick brothers, who refined their formula for years and trademarked malted milk in 1887. Malted drinks had already become familiar in pharmacies and soda fountains, which helped consumers embrace the flavor before malted milkshakes took off. Soon, soda fountain customers learned that a malt is a shake with malted milk powder added, giving the drink a fuller taste and slightly thicker body.

You also taste why it mattered. Light malt added a toasty note, a touch of umami, and caramelized grain sugars that lifted existing ice cream flavors instead of hiding them. At the same time, texture dynamics improved because malt, evaporated milk powder, and wheat flour created a thicker, smoother drink. That distinctive combination helped turn the malt into a soda fountain standard nationwide fast.

How Were Milkshakes Made Before Blenders?

Long before electric blenders hummed behind the counter, milkshakes came together through muscle, ice, and a lot of shaking. You'd combine crushed ice, milk, sugar, and flavorings in thick tumblers or jars, then shake hard for two to three minutes until the drink turned frothy. This was the standard method in the pre-electric era.

Early versions could include eggs and whiskey, but later you were more likely to use vanilla, chocolate, or strawberry syrup. The first use of the term milkshake in 1885 described an alcoholic tonic.

At soda fountains, bartenders handled everything by hand shaken methods or with hand cranked agitators like the Lightning Shaker. Some shops used early drink mixers, but the process still relied on manual action rather than modern blending.

You'd often start with half milk and half cream, finish with nutmeg, and depend on syrup mixing because liquid flavorings blended more smoothly into cold dairy than solid ingredients.

How Did the 1922 Blender Transform Milkshakes?

Stephen Poplawski changed milkshakes in 1922 when he invented the first electric blender with spinning blades at the bottom of a container.

You can trace a huge shift in soda fountains to that patent. Instead of hard manual shaking, you got faster mixing, electric frothing, and a reliable fluffy finish with one switch. That meant less labor, smoother service, and more consistent drinks every time. Before this change, early milkshakes often contained no ice cream, showing how the drink evolved over time. During the Roaring Twenties, the milkshake fit perfectly into an era of prosperity and leisure.

• Faster blending of milk, syrups, and add-ins
• Countertop convenience for busy soda fountain workers
• A foundation for restaurant and malt shop expansion

You'd see why it caught on quickly: it streamlined malt production and helped shops serve thicker, better-textured drinks with ease.

Later improvements by Fred Osius and others expanded Poplawski's idea, but his 1922 design started the blender revolution everywhere.

When Did Ice Cream Enter the Milkshake?

Pinning down exactly when ice cream entered the milkshake takes a little nuance, because the idea showed up before it became standard. If you trace the ice creamification timeline, you’ll find “ice cream milk shakes” advertised in America during the 1880s, not long after “milkshake” first appeared in print in 1885. Even so, those early versions stayed occasional treats because hand-mashing ice cream into drinks took real effort. In the soda fountain golden era of 1870–1900, drink categories were still clearly separated, with “milk shakes” distinct from “ice cream shakes.”

As you move into the early 1900s, milkshakes usually meant milk, syrup, crushed ice, or malted milk rather than scoops of ice cream. Soda fountains and ice cream parlors encouraged more dairy integration, but the practice wasn’t universal yet. So, you can say ice cream entered the milkshake in the 1880s, then became a regular expectation only in the early 1920s nationwide.

How Did Walgreens Popularize the Modern Milkshake?

Walgreens helped turn the milkshake into its modern form when Ivar “Pop” Coulson, working at a Chicago soda fountain in 1922, mixed two scoops of vanilla ice cream with milk, chocolate syrup, and Horlick’s malted-milk powder. You can trace today’s thick, creamy shake to Pop Coulson and his Malted innovation. At the Soda fountain, that frosty texture felt richer than earlier drinks, so customers kept coming back.

• You see the Walgreens legacy begin in one busy Chicago store.
• You get a family-friendly treat that matched 1920s leisure and indulgence.
• You watch soda jerks become trendsetters through one simple recipe.

As word spread, Walgreens turned a local favorite into a cultural staple. You can thank its affordable appeal, invigorating sweetness, and memorable texture for making the modern milkshake stick nationwide fast.

Which Inventions Helped Milkshakes Spread?

A handful of practical inventions helped milkshakes catch on far beyond the soda fountain counter.

First, Horlick’s malted milk powder gave you a safer, shelf-stable base and a nutty flavor. Then Stephen Poplawski’s 1922 electric blender, a Beverage Mixer with rotating blades, solved clumpy malt in cold milk and quickly whipped milk, ice cream, and syrups into smooth, frothy drinks. By the 1950s, milkshake mixing machines were common in diners, lunch counters, soda fountains, and burger joints, helping the drink spread even further.

Soon after, Hamilton Beach drink mixers appeared on drugstore counters, letting soda fountains make thicker, airier shakes and even extra-dense versions. In the 1930s, the bendy straw made those rich drinks easier to sip and more accessible. Later, Earl Prince’s automated milkshake machines standardized production, so restaurants could serve consistent shakes fast. Together, these inventions made milkshakes simpler to mix, serve, sip, and enjoy everywhere.

How Did Milkshakes Become an American Staple?

Those new tools did more than make milkshakes easier to mix—they helped turn them into a national favorite. As soda fountains boomed, you saw milkshakes shift from rare treats to creamy, nonalcoholic staples. Walgreens supercharged that change in 1922 with the double rich chocolate malt, then spread it nationwide fast. In the 1930s, better refrigerators and blenders made thick shakes consistent, affordable, and everywhere. Milkshakes also became a classic diner pairing with burgers and french fries.

• Soda fountains made shakes a social ritual.
• Walgreens transformed the drink with rich ice cream malt.
• Drive-ins tied shakes to burgers, freedom, and fun.
