A blender wins on volume, and it is the only one of the three that turns frozen fruit into a drink. A squeeze cup wins on everything around the drink: nothing to plug in, no noise, no blade, one portion, a minute of washing-up.
An ice cream maker is not in the same race. It makes something you eat with a spoon, which neither of the others can do.
What each one actually does
The squeeze cup
There is no motor and no ice. A freezing gel is sealed inside the wall of the cup, where it never touches the drink. Freeze the cup empty for four to six hours, overnight being easiest, then pour in a cold drink and squeeze: 30 to 60 seconds against the super-cooled inner wall and it turns to slush. The step by step is on our how it works page.
It holds 300 ml, roughly 10 fl oz. One drink, not a jug.
The blender
A blender does it by force. Blades break ice or frozen fruit into pieces small enough to drink, and it stays cold because the solids went in frozen. It needs those solids ready, and a socket.
The ice cream maker
An ice cream maker takes a third route. Ours, the FrostWhip Fruit Ice Cream Maker, is a 200 W machine built around a chute and a plunger: let frozen fruit soften for seven to ten minutes, feed it in, and soft serve comes out with nothing added. No bowl to pre-freeze, no churning cycle. We sell it, so that is a declared interest.

What a blender does better
- Volume. One jug serves a table. One cup is one drink, until it is frozen again.
- Frozen fruit. Mango, banana, berries, ice cubes. The cup takes liquid only.
- Thick shakes and smoothies. You set the thickness by the ratio of frozen to liquid. The cup gives one texture: slush.
- Spontaneity, if the freezer is stocked. Ice cubes keep for weeks. The cup only works if it went back in.
For six people, or a proper smoothie, use the blender; the cup has no argument to make. If you want slush without one, the options are in how to make a slushy without a blender.
What an ice cream maker does better
It makes something you eat rather than drink, from one ingredient. Frozen fruit goes in the chute, soft serve comes out, nothing is mixed in on the way. The cup takes liquid and gives back slush.
The cup handles dairy better than most people assume. Milk works, oat milk is the best dairy-free option, and the one to avoid is milk close to its date, as we set out in can you put milk in a slushy cup. What comes out is still a drink, not ice cream, and we will not claim otherwise.
What the cup does better
- Nothing to plug in. The freezer has done the work overnight, which puts a cold drink within reach in a caravan, an office kitchen, a shared student flat.
- Silence. You can make one at ten at night without waking the house. Nobody says that about a blender.
- Washing-up. A cup, a lid and a spoon-straw, by hand in lukewarm water with mild soap. No jug, no blade, no rubber seal. Never a dishwasher, never hot water: that damage is permanent, and once a cup has been through one it never slushes the same again.
- One portion. Nothing is left in a jug going watery on the counter.
- Safe to hand to a child. No blade, no motor, nothing to plug in, and the gel is sealed in the wall, away from the drink. Straight from a very cold freezer the walls are stiff, so give it a minute on the counter first.
Where the cup loses
Planning, mostly. It goes into the freezer empty for four to six hours at -18°C (0°F), and if nobody puts it back you will be let down on the first hot afternoon. For slush with no forethought, buy a machine.
Then the one-drink limit. Plenty of owners keep a spare cup frozen so one is always ready to pour into, and the bundles are set up for that: 10 percent off two, 15 off three, 20 off four or more.
And the sugar rule. Sugar gives slush its soft texture, so sugar-free and diet drinks set hard rather than slushy, and plain water freezes solid. A spoonful of sugar stirred in fixes it. What works and what does not is in our guide to the best drinks for a slushy cup.
So which one earns the shelf space
- One cold drink, quickly and quietly, and safe to hand a child: the cup.
- Frozen fruit, thick smoothies, or four drinks at once: the blender.
- Fruit soft serve to eat with a spoon: the ice cream maker.
Most kitchens already own a blender, and it stays in the cupboard because hauling it out and washing it for one drink is not worth it. That gap is why the cup exists. The Slushy Cup holds 300 ml, is made of BPA-free food-grade polymer, is hand wash only, comes in blue, green, yellow and pink, and is rated 4.7 from 1,277 reviews. Shipping is free worldwide and tracked, with a 30-day money-back guarantee that covers a change of mind. The rest is on our FAQ page.
Common questions
Do I still need a blender if I have a slushy cup?
If you make smoothies with frozen fruit, or drinks for several people, yes. The cup replaces a blender for single cold drinks, not for everything else.
Can a slushy cup make ice cream?
No. Milk works in the cup and oat milk is the best dairy-free option, but what you get is a drink rather than a dessert. Soft serve needs frozen fruit and a motor.
Which is safer to hand to a young child?
The cup. No blade, no motor, nothing to plug in, and the gel is sealed inside the wall. At 475 g it is light enough for a child to hold in both hands and squeeze.
