Frappe vs. Milkshake vs. Smoothie: What’s the Actual Difference?

You’re at a café, it’s hot out, and suddenly the cold drink menu looks a lot more complicated than it should.¶

There’s a frappe. A milkshake. A smoothie. Maybe a shake. Maybe a slush. If you’re in Rhode Island, maybe even something called a cabinet.¶

At first glance, they all seem like cousins: cold, sweet, blended, and served with a straw. But they’re not quite the same thing.¶

The easiest way to tell them apart is to look at what the drink is built around.¶

A milkshake is usually built around ice cream.A smoothie is usually built around fruit, vegetables, or both.A frappe is usually built around coffee and ice, although the meaning changes depending on where you are.¶

So if you’ve ever stared at a menu wondering about frappe vs. milkshake vs. smoothie, here’s the simple version. No drink-snob lecture. Just the stuff that actually helps you order the thing you want.¶

Here’s the short version:¶

• Milkshake: A thick, creamy dessert drink made with ice cream and milk.
• Smoothie: A blended drink made with whole fruit, vegetables, or both, plus a liquid like milk, juice, water, or coconut water.
• Frappe: Usually a cold, frothy coffee drink made with coffee, sugar, milk, and ice. But in some parts of New England, a frappe can mean an ice-cream-based milkshake.
• Shake: Often just a shorter way to say milkshake, but it depends on the menu.
• Slush: An icy drink made with crushed or blended ice and flavored syrup or juice, usually without dairy.
• Non-alcoholic dessert drinks: A broad category that includes milkshakes, malts, sweet frappes, ice cream drinks, and other rich cold treats.

The main lesson? Don’t trust the name alone. If you’re not sure, ask what’s actually in it.¶

The names can overlap, especially at cafés, diners, ice cream shops, and fast-food places. But the basic difference is pretty easy once you stop looking at the name and start looking at the base.¶

Ask three questions:¶

1. Is it thick because of ice cream?
2. Is it thick because of fruit, vegetables, or yogurt?
3. Is it coffee-based and blended with ice?

That usually tells you what you’re dealing with.¶

A milkshake gets its body from ice cream.A smoothie gets its body from fruit, vegetables, yogurt, or similar ingredients.A frappe usually gets its body from ice, foam, and coffee.¶

Of course, there are exceptions, because drink menus love making life harder than necessary. But those three rules will get you most of the way there.¶

A milkshake is the classic “dessert in a glass” drink.¶

The key ingredient is ice cream. Most milkshakes are made by blending ice cream with milk and some kind of flavoring. That might be chocolate syrup, vanilla, strawberry, caramel, peanut butter, cookies, fruit puree, coffee, or whatever special flavor the shop is pushing that week.¶

A good milkshake is thick, cold, smooth, and creamy. It should feel rich, not icy. The thickness usually comes from the ice cream, not from crushed ice.¶

That’s why milkshakes are usually thought of as dessert drinks. They’re sweet, dairy-based, and more indulgent than refreshing. If what you really want is something that tastes like melted ice cream with a straw, a milkshake is probably the right call.¶

• Usually made with ice cream
• Usually contains milk
• Often flavored with syrups, fruit, chocolate, cookies, caramel, or coffee
• Thick, creamy, and smooth
• Usually caffeine-free unless coffee, tea, or a lot of chocolate is involved
• More of a dessert than a light refreshment

A smoothie is usually built around whole fruit, vegetables, or both.¶

Instead of ice cream, smoothies get their thickness from ingredients like banana, mango, berries, avocado, spinach, yogurt, oats, or nut butter. The liquid can vary too. Some smoothies use dairy milk. Others use almond milk, oat milk, coconut water, juice, or plain water.¶

This is where the smoothie vs. milkshake difference becomes obvious.¶

A milkshake is dessert-first.A smoothie is usually produce-first.¶

That said, “smoothie” does not automatically mean healthy, light, or low sugar. Plenty of café smoothies are made with sweetened juice, sweetened yogurt, sherbet, fruit puree, or extra syrup. Some are basically dessert with a few strawberries blended in.¶

So if you want something fruit-based, order a smoothie. If you want something creamy and ice-cream-like, order a milkshake.¶

• Usually made with fruit, vegetables, or both
• May use milk, juice, water, yogurt, or plant-based milk
• Can be thick, pulpy, creamy, or icy
• Usually does not contain ice cream
• Usually caffeine-free unless matcha, tea, coffee, or similar ingredients are added
• Can be light, but not always

A frappe is the one that causes the most confusion.¶

In the traditional sense, a frappe is a cold, frothy coffee drink made with coffee, sugar, milk, and ice. It’s shaken or blended until it becomes foamy and icy. Compared with a milkshake, it’s usually lighter, colder, and less creamy.¶

The simplest way to understand frappe vs. milkshake is this:¶

A frappe is usually thickened with ice and foam.A milkshake is thickened with ice cream.¶

So if you order a traditional frappe, you should expect something closer to an icy coffee drink than a rich ice cream dessert. It can still be sweet, but it usually won’t feel as heavy as a milkshake.¶

The tricky part is that modern menus use the word “frappe” pretty loosely. Some coffee shops use it for sweet blended coffee drinks that are almost milkshake-like. Some places sell cream-based frappes with no coffee at all. Others use the word for nearly any blended iced drink with whipped cream on top.¶

So yes, sometimes you really do have to ask.¶

• Traditionally coffee-based
• Usually blended with ice
• Often includes milk and sugar
• Frothy, icy, and lighter than a milkshake
• Usually contains caffeine
• Can mean different things depending on the café or region

Here’s where things get even more fun: these words don’t mean the same thing everywhere.¶

Depending on where you are, frappe, milkshake, shake, and cabinet can mean slightly different drinks. The general definitions are useful, but local habits matter.¶

In parts of New England, especially Massachusetts, a “frappe” can mean an ice-cream-based drink that many other places would simply call a milkshake.¶

In some local shops, a “milkshake” may mean milk mixed with flavored syrup, but no ice cream. If you want the thick ice cream version, you may need to order a frappe, often pronounced “frap.”¶

So if you ask, “What is a frappe?” in Boston, you may get a very different answer than you would at a coffee chain somewhere else.¶

In Rhode Island, an ice-cream-based blended drink may be called a cabinet.¶

It’s basically a local name for what many people elsewhere would call a milkshake or frappe. The name is often said to come from the cabinets where ingredients or equipment were stored.¶

But if you’re ordering one, you don’t really need the history lesson. The practical point is simple: if you see “cabinet” on a Rhode Island menu, it probably means a thick ice cream drink.¶

Still, it never hurts to ask.¶

A lot of cafés use “frappe” as a general word for cold blended drinks. Some have coffee. Some don’t. Some are milk-based. Some are cream-based. Some are almost like slushes. Some are basically dessert drinks with whipped cream and syrup on top.¶

That doesn’t necessarily mean the menu is wrong. It just means the word has stretched over time.¶

A “shake” is usually just short for milkshake, especially at diners, ice cream shops, and fast-food places.¶

If you order a chocolate shake at a burger place, you’re probably getting a chocolate milkshake.¶

But not always.¶

Some menus use “shake” for protein shakes, breakfast shakes, meal replacement drinks, or blended drinks that don’t contain ice cream at all. A “green shake” or “wellness shake” may be closer to a smoothie than a milkshake.¶

So again, check the base. If it has ice cream and milk, it’s a milkshake. If it has protein powder, greens, oats, or fruit, it may be something else.¶

A slush is a cold, icy drink made with flavored liquid and ice. It’s usually not creamy and usually does not contain dairy.¶

Think of a slush as the icy cousin in this group. It’s not trying to be rich like a milkshake or produce-heavy like a smoothie. It’s mostly about crushed ice and flavor.¶

A slush might be made with syrup, juice, soda, or a flavored mix. The texture is usually grainy, icy, and refreshing.¶

Compared with the others:¶

• A slush is icier than a smoothie.
• A slush is lighter than a milkshake.
• A slush usually does not contain coffee like a traditional frappe.
• A slush is usually sweet and refreshing, not creamy.

If you want something cold, sweet, icy, and usually dairy-free, a slush may be the best choice.¶

A lot of these drinks fall into the larger category of non-alcoholic dessert drinks.¶

That can include:¶

• Milkshakes
• Malts
• Sweet frappes
• Ice cream drinks
• Floats
• Very sweet smoothies
• Blended drinks with whipped cream, syrup, or candy toppings

The biggest clue isn’t the name. It’s the ingredient list.¶

If you see things like these, you’re probably looking at a dessert drink:¶

• Ice cream
• Sweetened syrups
• Chocolate sauce
• Caramel
• Whipped cream
• Sweetened condensed milk
• Candy toppings
• Sweetened yogurt
• Sherbet

There’s nothing wrong with that. Sometimes you want a treat, and that’s the whole point. But those ingredients tell you the drink is more dessert than light refreshment.¶

If you’re choosing between a frappe and a milkshake, ask yourself one simple question:¶

Do I want coffee and ice, or ice cream and milk?¶

Choose a frappe if you want:¶

• A cold coffee drink
• A frothy, icy texture
• Something lighter than a milkshake
• A caffeine boost
• A café-style blended drink

Choose a milkshake if you want:¶

• A creamy dessert
• Ice cream
• A thicker, richer texture
• A sweet treat without coffee
• Something classic and indulgent

Just remember: in parts of New England, this can flip, because “frappe” may mean the ice cream drink.¶

If you’re deciding between a smoothie and a milkshake, the question is:¶

Do I want fruit as the base, or ice cream as the base?¶

Choose a smoothie if you want:¶

• Fruit or vegetables
• A snack-style drink
• Something that may include fiber from whole fruit
• A drink that can be made dairy-free pretty easily
• A lighter option than a milkshake, depending on the ingredients

Choose a milkshake if you want:¶

• Ice cream
• A creamy dessert drink
• A thicker, richer texture
• A classic sweet treat

A smoothie can still be very sweet. A milkshake can still have fruit in it. The difference is what the drink is built around.¶

Cold drink menus can be vague, especially when you’re traveling or trying a new café. One shop’s “frappe” might be another shop’s “shake.” One smoothie might be mostly whole fruit, while another might be mostly juice and syrup.¶

The safest move is to ask a few simple questions.¶

• “Does this frappe have coffee?”
• “Is it made with ice cream or blended ice?”
• “Is the smoothie made with whole fruit or syrup?”
• “Does the shake contain ice cream?”
• “Can this be made without dairy?”
• “Is there added sugar or sweetened syrup?”
• “Is the ice made from filtered or bottled water?”

These questions are especially useful if you’re ordering for kids, avoiding caffeine, avoiding dairy, watching sugar, or traveling somewhere with different food safety standards.¶

Cold blended drinks are fun, but there are a few practical things worth paying attention to.¶

Milkshakes and many frappes contain dairy. Some smoothies do too, especially if they’re made with milk, yogurt, ice cream, or dairy-based powders.¶

If you avoid dairy, don’t assume a smoothie is dairy-free. Ask what’s in it.¶

When traveling, it’s also smart to choose busy, reputable places where dairy ingredients are clearly being kept cold. Milk, yogurt, and ice cream need proper refrigeration. If a place looks questionable, it may be better to skip dairy-based drinks.¶

Milkshakes are usually sweet because they’re made with ice cream and flavorings. Frappes often include sugar or flavored syrup. Smoothies can also be surprisingly sweet if they’re made with juice, sweetened yogurt, syrup, sherbet, or fruit puree.¶

If you want something less sweet, ask:¶

• “Can you make it with less syrup?”
• “Is the fruit sweetened?”
• “Can I get it without whipped cream?”
• “Is the base juice or whole fruit?”

Small questions like that can keep you from accidentally ordering something that tastes like liquid candy, unless that’s exactly what you’re after.¶

Traditional frappes usually contain coffee, which means they usually contain caffeine. Coffee-flavored milkshakes may also contain caffeine, depending on how they’re made.¶

If you’re ordering for a child or avoiding caffeine, ask directly. Don’t rely on the flavor name alone. A “vanilla frappe” might be caffeine-free at one café and coffee-based at another.¶

Frappes, smoothies, and slushes often rely heavily on ice. If you’re somewhere the tap water isn’t considered safe to drink, be careful with blended ice drinks.¶

Ask whether the ice is made from filtered or bottled water. If you’re not sure, choose a sealed bottled drink or something made without ice. For fruit drinks, peelable fruits and sealed bottled liquids are usually safer when local water safety is uncertain.¶

Here’s the easiest way to think about it.¶

Order a milkshake when you want dessert in a glass: thick, creamy, sweet, and ice-cream-based.¶

Order a smoothie when you want a fruit- or vegetable-based blended drink. It may still be sweet, but it’s usually more produce-focused.¶

Order a frappe when you want an icy coffee-style drink, unless you’re somewhere that uses “frappe” to mean milkshake.¶

Order a slush when you want something icy, sweet, refreshing, and usually dairy-free.¶

Order a shake when you want a milkshake, but double-check if the menu seems health-focused, protein-focused, or regional.¶

The best trick is simple: ignore the fancy name for a second and ask what gives the drink its body.¶

Is it ice cream? Fruit? Coffee? Ice?¶

That answer tells you what you’re actually getting.¶
