Frappe vs Milkshake: Key Differences Explained

Walk into any cafe and order a frappe. Then order a milkshake at the next counter. You will get two different drinks, but the lines blur fast. People argue about which is which all the time. The confusion is fair because the words have changed meaning over the last fifty years.

This guide breaks down the technical differences, the history, and the practical choices. You will know exactly what to order and how to make each at home.

The Short Answer

A milkshake is cold milk, ice cream, and flavoring blended until thick and creamy. A frappe is a blended iced drink that originally meant coffee, but now often means a thick, sweet, milkshake-like treat without ice cream.

That is the core split. One is dairy-forward with ice cream as the base. The other is usually coffee or syrup-based, relying on ice for texture.

But the story is messier than that. Regional habits and marketing campaigns shifted the definitions.

Where the Term Frappe Came From

The word frappe comes from French. It means ‘struck’ or ‘chilled.’ In Europe, a frappe was simply a drink poured over ice.

The Greek frappe changed everything. In 1957, a Nestle representative at a trade fair in Thessaloniki shook instant coffee with cold water and ice in a cocktail shaker. The result was a foamy, cold coffee drink. It became a national sensation.

That Greek version uses instant coffee, water, sugar, and ice. No milk is required, though many add it. It is shaken, not blended, and served over ice cubes.

So the original frappe was a coffee drink. It was not a dessert. It was not thick.

When Frappe Became a Milkshake

American chains like McDonald’s took the term and changed it. They introduced the McCafe Frappe, which is a blended coffee drink with syrup, milk, and ice. It sits somewhere between a coffee and a milkshake.

Then regional fast-food places started calling any thick blended drink a frappe. Some used ice cream. Some did not. The word lost its strict coffee-only meaning.

That is the shift in standard advice. Twenty years ago, the rule was simple: frappe means coffee, milkshake means ice cream. That advice is now wrong for many places. The market redefined the frappe as a dessert-style blended drink.

What Changed and What Did Not

The core definition of a milkshake has not budged. It still requires ice cream or a thick dairy base. That is stable across every region and era.

The frappe definition is the one that moved. It went from a shaken iced coffee to a blended, sweet, often dessert-like drink.

Advice that is now simply wrong: ‘A frappe is always coffee.’ That is false in the US market today. Many frappes are caramel, chocolate, or fruit-flavored with zero coffee.

Advice that was always situational: ‘A frappe is healthier than a milkshake.’ That depends entirely on the recipe. A coffee frappe with skim milk and no sugar beats a heavy milkshake. A caramel frappe with whipped cream does not.

Key Differences in Ingredients

The ingredient list tells you everything. A milkshake starts with ice cream. Vanilla, chocolate, or strawberry ice cream forms the base. Milk thins it out. Syrup or fruit adds flavor.

A frappe starts with ice. Coffee or syrup flavors the ice. Milk or cream adds richness. The texture comes from blending ice into a slushy consistency.

That difference in base changes the mouthfeel. Milkshakes are dense and spoonable. Frappes are lighter and drinkable through a straw.

There is an exception. Some cafes make a ‘frappe milkshake’ that uses both ice cream and ice. That hybrid is thick like a milkshake but colder and more granular.

Texture and Consistency

Milkshakes rely on soft-serve or hard ice cream. The churning and blending create air pockets. That gives a smooth, heavy, almost mousse-like texture.

Frappes rely on crushed ice. The blender pulverizes the ice into tiny crystals. The drink is wetter and thinner than a milkshake, even when creamy.

Hold a straw in each. A milkshake straw stands straight up. A frappe straw will slowly tilt unless the drink is very thick.

Temperature matters too. A milkshake is cold but not icy. A frappe is colder because of the ice content, which can dull the flavor of delicate ingredients.

How They Are Made

Milkshake method: scoop ice cream into a blender, add a splash of milk, blend briefly. You want it thick enough that it barely moves in the cup.

Frappe method: fill a blender with ice, add liquid (coffee, milk, syrup), blend on high until smooth. The ice-to-liquid ratio controls the thickness.

The tools differ too. A standard blender works for both. But a milkshake machine (the old spindle type) only works for milkshakes because it does not crush ice.

For home use, a personal blender with a strong motor handles both jobs. The personal blender milkshake method works well for single servings.

Nutritional Reality

Neither drink is a health food. A standard milkshake has 400 to 700 calories depending on size and toppings. A frappe lands in the same range.

The sugar content is the hidden problem. A flavored frappe often packs more sugar than a milkshake because the syrup is poured by hand. You cannot taste the difference because the ice masks the sweetness.

If you want a lighter option, ask for a frappe without syrup and with skim milk. That cuts calories significantly. A milkshake has no such easy fix because the ice cream is non-negotiable.

Dairy alternatives change the picture. Milk alternatives for milkshakes like oat or almond milk work, but they make the drink thinner. You need more ice cream to compensate.

Regional Variations

New England has a different rule. In Rhode Island and Massachusetts, a ‘frappe’ specifically means a thick milkshake with ice cream. A ‘milkshake’ there means flavored milk with no ice cream.

That is the opposite of the Greek definition. It shows how local usage overrides any global standard.

In the Midwest, the term ‘turtle’ or ‘concrete’ appears for extra-thick shakes. In the South, a ‘malt’ includes malted milk powder. These are all variations on the milkshake theme.

The lesson is simple: ask what the menu means before ordering. The word alone does not tell you what is in the cup.

Which One Should You Order?

Choose a milkshake when you want a dessert. It is rich, filling, and tastes like melted ice cream. It pairs well with a burger or fries.

Choose a frappe when you want something cold and caffeinated. It is lighter than a milkshake and works as a mid-afternoon pick-me-up.

Choose a frappe over a milkshake if you dislike the heavy mouthfeel of ice cream. The ice-based texture is less coating.

Choose a milkshake over a frappe if you want a drink that stays thick to the last sip. Frappes separate as the ice melts, leaving a watery bottom layer.

Making Both at Home

You do not need a commercial machine for either. A decent countertop blender is enough. The Mr. Coffee 3-in-1 Single-Serve Iced and Hot Coffee/Tea Maker with Blender handles both drinks in one unit.

That machine brews hot coffee or iced coffee up to 22 ounces, then blends it into a frappe using the built-in blender. It also includes a recipe book, two tumblers with lids and straws, a reusable filter, and a scoop. The 12.6 x 12.0 x 15.7 inch footprint fits on most counters.

For a milkshake, use the same blender jar. Add two scoops of ice cream and a quarter cup of milk. Blend for 30 seconds. The machine’s automatic blending cycle stops at the right consistency.

For a frappe, brew strong coffee first, let it cool, then blend it with ice and milk in the same jar. The precision measurement markings on the carafe help you get the water-to-coffee ratio right.

Common Myths

Myth: A frappe is always iced coffee. Wrong. Many commercial frappes are coffee-free.

Myth: A milkshake must be made with a blender. Wrong. The classic method uses a milkshake machine with a spindle.

Myth: A frappe is healthier. Not automatically. The syrup and whipped cream add calories fast.

Myth: You cannot make a milkshake without ice cream. You can use frozen yogurt or thick Greek yogurt, but the result is not a true milkshake.

Frequently Asked Questions

Is a frappe just a milkshake with coffee?

Not always. A frappe can be coffee-flavored, but many are not. The defining factor is the ice base, not the coffee.

Which one is colder?

A frappe is colder because it contains more ice. The ice crystals lower the overall temperature below that of a milkshake.

Can I use the same blender for both?

Yes. Any blender that crushes ice and mixes thick liquids works for both drinks. The Mr. Coffee 3-in-1 mentioned above is one example.

Why does my frappe separate after a few minutes?

Ice melts and dilutes the liquid. Blending in a stabilizer like xanthan gum or a scoop of ice cream prevents separation.

What is the difference between a frappe and a smoothie?

A smoothie uses fruit and juice or yogurt as the base. A frappe uses coffee or syrup with ice. The flavor profiles rarely overlap.

Can I make a frappe without a blender?

You can shake it in a cocktail shaker, like the original Greek recipe. But the texture will be foamy, not slushy.

The Bottom Line

The words have shifted, but the drinks remain distinct. A milkshake is an ice cream dessert in a cup. A frappe is a blended ice drink that may or may not include coffee.

Order based on what you want, not what you think the name means. Ask the barista if the frappe contains coffee. Ask if the milkshake uses real ice cream.

The best choice is the one that tastes good to you. Both drinks have their place. Neither is superior. They are just different tools for the same job: cooling you down and making you happy.
