Buy the ICE-21P1 unless the overnight pre-freeze is a problem you have actually had. It was America's Test Kitchen's best canister-style pick at $70 in June 2026 and it makes the same 1.5 quarts as the ICE-100, which ATK listed at $343. Buy the ICE-100 if you want ice cream on impulse, or two flavors in one evening, or gelato with its own paddle. Those three things are the entire difference, and the price gap is roughly five to one.
This is the cleanest upgrade question in the Cuisinart range because the output is not really in dispute. Ice Cream Science rates the canister machines' texture as smooth and creamy, and the base recipes are identical in both machines. What separates them is the source of the cold: the ICE-21P1 spends cold that you stored in a bowl the day before, and the ICE-100 makes its own as it goes.

What the extra money actually buys
One thing: the removal of a 16-to-24-hour wait. Everything else follows from it.
A canister machine is a thermal battery. The bowl holds a fixed amount of cold, you spend it over a single churn, and when it is gone the bowl has to go back in the freezer for most of a day. That is why the ICE-21P1 cannot make two flavors in one evening, and it is why ice cream on an ICE-21P1 is always a decision you made yesterday. The full mechanism is in compressor versus freezer bowl, and the bowl timing specifically is in how long to freeze an ice cream maker bowl.
The ICE-100 has a refrigeration circuit instead. It chills the bowl while the paddle turns, so you pour the base in and walk away, and when the batch is out you can start another. That is a different relationship with the machine: dessert becomes a tonight decision rather than a tomorrow one, which in practice is the difference between a machine that gets used weekly and one that gets used in July.
The honest test before you spend $270 extra
Count the times in the last year you wanted homemade ice cream and could not have it because nothing was frozen. If the answer is “most times I thought about it,” the compressor is the right buy and it will pay for itself in batches you actually make. If the answer is “I make ice cream three times a summer and I plan it,” the ICE-21P1 is the right buy and the difference belongs in better cream and real vanilla. We argue the whole case in is an ice cream maker worth it.
The second paddle, which is a real difference
The ICE-100 ships two paddles rather than one: an ice cream paddle shaped to fold air into a custard base, and a gelato paddle shaped to work a denser mixture with much less air folded in. Air content is the actual difference between ice cream and gelato, not the recipe, and our overrun explainer covers why. Machines that offer a “gelato mode” approximate this by slowing the paddle down. A paddle built for the job moves the mixture differently, which is a hardware answer to a hardware problem.
If you have read gelato versus ice cream and decided gelato is what you want, this is the cheapest Cuisinart that will do it properly, and it is the reason the ICE-100 also leads the gelato roundup. If you are never going to make gelato, the second paddle is a $270 accessory you will leave in a drawer, and you should price the machine on the pre-freeze alone.
What the ICE-21P1 wins, and it is not only price
- Speed of churn. Dream Scoops measured the ICE-21P1 at roughly 15 to 20 minutes, which is among the fastest in the category. The ICE-100 runs on a 60-minute timer because a compressor has to pull the heat out of a room-temperature bowl as well as the base.
- Counter space. 9 inches wide by 9.25 deep against 12 by 16.73. The ICE-100 needs more than half a standard counter depth and weighs 28 pounds, which means it lives out permanently. The ICE-21P1 genuinely fits in a cupboard.
- Nothing to fail. A 60-watt motor and a switch, against a 288-watt refrigeration circuit. A canister machine is the simpler object by a wide margin, and Ice Cream Science reports roughly seven years of use from the related ICE-30BCP1 while still rating its output well.
- Cheap second bowls. Spare ICE-21 freezer bowls are sold separately, which is the budget route to two flavors in one day — the trade is examined in do you need a second freezer bowl.
Two honest marks against it. Dream Scoops measured it at 79 to 82 decibels during a churn, which is loud for twenty minutes in a small kitchen, and the bowl occupies real freezer space all year if you want to stay ready. Neither is a reason to spend five times more, but both are reasons people end up annoyed with an otherwise excellent machine.
What the ICE-100 costs you beyond the price
Twenty-eight pounds and 16.73 inches of counter depth for 1.5 quarts is a poor ratio, and it is the main criticism of this machine. The Whynter ICM-201SB is the same kind of machine at a similar price and holds 2.1 quarts, which ATK named their best self-refrigerating pick at $310 in June 2026 — that head-to-head is ICE-100 versus ICM-201SB. Compressors are also loud while they run, and unlike a canister machine the noise is a permanent feature of the appliance rather than twenty minutes of churn.
The compensation is the warranty. Three years in the US is unusually long in this category, and on a machine with a refrigeration circuit it is worth more than it would be on a 60-watt motor. Dream Scoops calls the ICE-100 the best value alternative to a several-hundred-dollar Italian machine such as the Lello 4080, which is the fairest one-line summary of where it sits.
The options in between
There are two, and both are worth knowing before you commit to either end of this page. The ICE-30BCP1 is the same freezer-bowl mechanism at 2 quarts in a brushed stainless housing, ATK Recommended at $100 — more capacity, same planning, as ICE-21 versus ICE-30 sets out. The ICE-70P1 adds an LCD countdown and three texture programs on top of that.
Neither removes the pre-freeze. That is the point worth being clear about: within the Cuisinart range, the only way to stop planning a day ahead is the compressor, and the ICE-100 is the cheapest one. Everything below it buys capacity or controls instead. The full brand ladder is ranked in best Cuisinart ice cream makers.
The verdict
- First machine, and you are willing to plan: ICE-21P1. It is the best value in the category and ATK agrees.
- Ice cream on impulse, or two flavors tonight: ICE-100.
- Gelato specifically: ICE-100, for the second paddle.
- Compressor money but you need more than 1.5 quarts: Whynter ICM-201SB at 2.1 quarts.
Both machines get the full treatment in the ICE-21P1 review and the ICE-100 review. If you have not decided on a mechanism at all yet, start with how to choose an ice cream maker.
