You’re standing in the grocery aisle, staring at a pint of premium salted caramel gelato that costs nine bucks. Nine dollars! You look at the back of the carton. It’s full of guar gum, carrageenan, and "natural flavors" that feel anything but natural. This is usually the exact moment people start googling the Cuisinart ice cream and frozen yogurt maker.
It's a classic.
Honestly, the ICE-21 and its big brother, the ICE-30, have been around for what feels like forever. In a world where kitchen gadgets get "smart" upgrades every six months, these machines are weirdly low-tech. No Bluetooth. No touchscreens. Just a motor, a frozen bowl, and a plastic paddle. But here’s the thing: they actually work better than the fancy stuff.
The Science of the "Freeze-First" Method
Most people don't realize that making ice cream at home is basically a race against ice crystals. If you freeze a liquid slowly, you get big, crunchy shards of ice. That's gross. You want tiny crystals. You want smooth. To get that, you need a high-speed churn and a surface that is biting cold.
The Cuisinart ice cream and frozen yogurt maker uses a double-insulated freezer bowl filled with a cooling liquid. You have to stick that bowl in the back of your freezer for at least 16 to 24 hours. If you shake it and hear a sloshing sound? It's not ready. Put it back. This is the part that trips everyone up. Your freezer needs to be set to 0°F or colder. If your freezer is stuffed with five-year-old bags of peas and can't reach that temperature, your ice cream will stay a sad, milky soup.
Why the ICE-21 is Basically Bulletproof
Let’s talk about the design. It's almost stupidly simple. There is a base with a heavy-duty motor. You put the frozen bowl on the base, drop in the mixing paddle, and turn it on. The bowl spins while the paddle stays still.
It’s loud.
It sounds like a small airplane taking off on your counter. But that motor is a beast. Whether you’re making a thin dairy-free almond milk blend or a thick, heavy cream custard, it keeps spinning. Most competitors use a design where the paddle spins and the bowl stays still. Those usually have weaker motors that burn out or jam when the ice cream gets thick. Cuisinart’s "spinning bowl" design uses the weight of the mixture to its advantage.

What People Get Wrong About "Healthy" Frozen Yogurt
The name of the machine says "Frozen Yogurt," so naturally, people think they can just dump a tub of Fage into the bowl and call it a day.
Don't do that.
Store-bought yogurt is already fermented and set. If you churn it straight, it turns into a block of sour ice. To get that Pinkberry-style texture, you need a specific ratio of sugar to fat. Sugar isn't just for taste; it acts as an anti-freeze. It lowers the freezing point of the water in the yogurt so it stays soft enough to scoop.
Kinda ironic, right? To make "healthy" frozen yogurt in your Cuisinart ice cream and frozen yogurt maker, you usually have to add a fair amount of sugar or honey to keep it from turning into a rock. Serious eats expert Stella Parks has noted that for the best home results, using a high-fat Greek yogurt mixed with a sugar syrup is the only way to avoid the dreaded "ice-cube" effect.
The 20-Minute Sweet Spot
The biggest sell for this machine is speed. Once that bowl is frozen, the actual churning time is usually between 15 and 25 minutes.
That's it.
You’re basically making soft serve. If you want "hard" ice cream like you get at the store, you have to scrape it out of the bowl and put it in a container in the freezer for a few hours. This is called "ripening."

But honestly? Eating it straight out of the machine when it's the texture of a Wendy's Frosty is the peak experience. Just don't use metal spoons to scrape the bowl. You’ll scratch the lining, and then everything will start sticking. Use silicone or rubber spatulas. Always.
Comparison: ICE-21 vs. ICE-30 vs. ICE-70
If you're shopping for a Cuisinart ice cream and frozen yogurt maker, the model numbers are confusing.
- The ICE-21 is the 1.5-quart standard. It’s the cheapest. It has the best reviews. It’s the one most people should buy.
- The ICE-30 (Pure Indulgence) is a 2-quart model. It looks nicer because it’s brushed metal, but it’s even louder than the 21.
- The ICE-70 is the "fancy" one. It has a timer and a countdown display. It also has a "Gelato" setting which just slows down the motor.
Is the ICE-70 worth it? Probably not. Gelato is technically defined by having less "overrun"—which is a fancy word for air. To make real gelato, you need a machine that churns very slowly. While the ICE-70 tries to do this, it's still a centrifugal freezer bowl machine. You're better off saving the $60 and getting the basic ICE-21.
Dealing With the Limitations
It’s not all sunshine and sprinkles. The biggest drawback is the "one and done" nature of the freezer bowl. If you want to make two batches in one night, you’re out of luck unless you buy a second bowl. The bowl takes a full day to recharge.
Also, the center of the bowl stays colder than the edges. You’ll notice a thin layer of "ice cream skin" that freezes hard to the sides. Some people try to scrape it off while the machine is running. Don't. You’ll just jam the paddle and potentially strip the gears in the motor. Let the machine do its thing.
Surprising Things You Can Actually Make
It’s not just for dairy.
- Dole Whip Dupe: Canned pineapple juice, a bit of cream or coconut milk, and sugar.
- Aperol Spritz Sorbet: Yes, you can freeze alcohol, but only in small amounts. Too much booze and it won't set. A splash of Aperol and prosecco with a grapefruit base makes a killer adult slushie.
- Coffee Granita: Strong espresso and sugar. Churn it for 10 minutes for a flaky, caffeinated treat.
The Cuisinart ice cream and frozen yogurt maker is remarkably forgiving with sorbets because they don't have the fat proteins that can get "buttery" if over-churned.

Practical Maintenance Tips for Longevity
Never, ever put the freezer bowl in the dishwasher. The heat will ruin the cooling liquid inside, and then you just have an expensive bucket. Let it come to room temperature naturally before washing it with warm, soapy water.
If you put a frozen bowl into hot dishwater, the thermal shock can crack the seal.
Also, keep the motor base clean. If mix drips down into the spindle, it can get sticky and eventually seize the motor. A quick wipe with a damp cloth after every use is usually enough to keep it running for a decade. These things are known to last 10+ years if you don't abuse the motor.
The Economics of Home Churning
Is it cheaper to make your own?
Probably not at first. You’ve got the $50-$70 for the machine, plus the cost of heavy cream, which has skyrocketed lately. However, if you have allergies or specific dietary needs—like keto, vegan, or low-FODMAP—the machine pays for itself in about ten batches. Specialty pints at the store are often $8 to $12. You can make a 1.5-quart batch of high-end oat milk chocolate ice cream for about $5 in ingredients.
Actionable Next Steps
If you’re ready to stop buying overpriced pints, here is your immediate game plan:
- Check your freezer space: Make sure you have a flat spot in the coldest part of your freezer (usually the back) where the bowl can sit upright for 24 hours.
- Start with the "Simple Vanilla" recipe: Use the one in the Cuisinart manual. It uses heavy cream, whole milk, and sugar. No eggs. No cooking. It’s the easiest way to calibrate your expectations.
- Buy a dedicated container: Don't store your finished ice cream in the freezer bowl. It will turn into a brick. Buy a long, insulated "ice cream tub" (brands like Sumo or Tovolo work great) that allows for long, professional-looking scoops.
- Chill your base: This is the most important tip. If you mix your ingredients and they are room temperature, the freezer bowl will lose its "cold" before the ice cream is finished. Chill your liquid mix in the fridge for at least 4 hours before pouring it into the machine.
By following these steps, you ensure the motor doesn't strain and the texture remains silky rather than icy. The Cuisinart ice cream and frozen yogurt maker is a tool, and like any tool, the results are only as good as the preparation you put into it.
