The Cuisinart ICE-21 and the Cuisinart ICE-30BC are two of the most popular ice cream makers on the market, but they differ primarily in capacity and exterior design. The ICE-21 is a 1.5-quart model with a plastic housing perfect for individuals or smaller households, while the ICE-30BC offers a larger 2-quart capacity and a more premium stainless steel finish, making it better for families or entertaining.
Here’s a detailed look at both models to help you decide which Cuisinart ice cream maker is right for your kitchen.
Cuisinart ICE-21 Frozen Yogurt, Ice Cream & Sorbet Maker
The ICE-21 is Cuisinart's classic, no-fuss entry into homemade frozen desserts. It works using a double-insulated freezer bowl that you pre-freeze, then the machine's motor churns your mixture into a smooth treat. Its simple one-switch operation and compact size have made it a bestseller for years for those who want consistent results without complexity.
- What it is: A fully automatic countertop ice cream maker that uses a pre-frozen bowl.
- Key features: 1.5-quart capacity, double-insulated freezer bowl, easy-lock lid with a large ingredient spout, and a heavy-duty motor. Operation is a simple on/off switch.
- Price: Around $70
- Dimensions: 9.5" x 9.0" x 11.25"
- Operation Time: Produces frozen desserts in 20 minutes or less after the bowl has been completely frozen.
- Materials/Construction: Durable plastic housing. The freezer bowl contains cooling liquid between its double walls.
- Pros: Very affordable entry-level price. Extremely simple to use with just one switch. Compact footprint doesn't take up much counter space. Consistently produces great quality ice cream.
- Cons: Requires you to plan ahead and freeze the bowl for 12-24 hours. The smaller 1.5-quart capacity may not be enough for larger families. You can't make back-to-back batches without a second frozen bowl.
The ICE-21 is a perfect fit for individuals, couples, or small families looking for the most affordable and straightforward way to start making ice cream at home.

Cuisinart ICE-30BC Pure Indulgence™ 2-Quart Maker
The Cuisinart ICE-30BC operates on the same reliable freezer-bowl technology as its smaller sibling but increases the output and wraps it in a more stylish package. With a 2-quart capacity, it’s designed for those who want to make larger batches for family gatherings, parties, or weekly meal-prepping. The upgrade to a brushed stainless steel exterior also gives it a more premium look on the counter.

- Key features: 2-quart capacity, double-insulated freezer bowl, easy-lock lid with ingredient spout, powerful motor to handle larger batches.
- Price: Around $100
- Dimensions: 8.25" L x 8.00" W x 11.25" H
- Operation Time: Churns frozen desserts in about 20-25 minutes once the bowl is completely frozen.
- Materials/Construction: The housing is a durable and sleek brushed stainless steel, making it look more like a high-end appliance.

- Cons: Like the ICE-21, you must pre-freeze the bowl. The larger 2-quart bowl takes up more valuable freezer real estate. Slightly more expensive.

Cuisinart ICE-21 vs. ICE-30BC Comparison
Capacity & Batch Size
The most significant difference is the batch size. The Cuisinart ICE-21 produces 1.5 quarts (about 6 cups) of ice cream, which is perfect for 2-4 people. It's great for desserts or smaller treats throughout the week.
In contrast, the Cuisinart ICE-30BC makes 2 quarts (8 cups), offering about 33% more per batch. This larger volume is much better suited for families of four or more, or for serving guests at a dinner party. If you don't want to worry about running out, the ICE-30BC is the clear winner here.
Design & Footprint
While their function is similar, their looks are distinct. The ICE-21 features a simple, practical plastic body, usually in white. The ICE-30BC has a brushed stainless steel housing, giving it a more modern and premium kitchen appliance feel.
Interestingly, despite the larger internal bowl, both machines have virtually the same countertop footprint. Neither is particularly large, but the fact that the ICE-30BC doesn't require more counter space is a big plus. The main size consideration is freezer space - the ICE-30BC's 2-quart bowl is wider and taller, demanding more room to freeze properly.
Usability & Performance
Both models could not be simpler to use. They each feature a single on/off switch. You just pour your chilled mixture into the pre-frozen bowl, put the lid on, and flip the switch. Both will turn out smooth, creamy ice cream in roughly 20 to 25 minutes. Performance is a tie, as they share the same effective motor and churning design, just scaled for their respective capacities.
The key usability limitation for both is the freezer bowl. It must be frozen completely solid (typically 12 hours minimum, often up to 24) to work effectively. This means you can't make ice cream spontaneously and are limited to one batch per day unless you buy a second bowl.
Price & Value
The ICE-21 is the more budget-friendly option, usually costing around $70. It offers fantastic value for anyone new to ice cream making or with smaller capacity needs. It's often considered one of the best "bang for your buck" appliances you can buy.
The ICE-30BC is priced slightly higher, at around $100. For the extra money, you get that critical increase in capacity and a more durable, stylish exterior. If you have the freezer space and know you'll be making bigger batches, the small price jump represents excellent value for what you receive.
Which One Should You Choose?
Both Cuisinart ice cream makers are excellent, but they are built for slightly different users.
Choose the Cuisinart ICE-21 if:
- You're usually making dessert for just one to three people.
- You are on a tighter budget and want the most affordable starting point.
- You have limited space in your freezer for the bowl.
- You make ice cream occasionally and don't need large quantities.
Choose the Cuisinart ICE-30BC if:
- You have a family of four or more or frequently have guests over.
- You want a larger batch size to have leftovers.
- You prefer the look of a premium, stainless steel appliance.
- You have adequate freezer space for a larger bowl and don't mind the slightly higher cost.
Frequently Asked Questions
What's the main difference between the Cuisinart ICE-21 and ICE-30?
The primary difference is capacity and materials. The ICE-21 has a 1.5-quart capacity and a plastic exterior, while the ICE-30BC has a 2-quart capacity and a more premium brushed stainless steel exterior.
Do I need to freeze the bowl for these ice cream makers?
Yes, both models use freezer bowl technology. You must place the double-walled bowl in a freezer for at least 12-24 hours until it is completely solid before you can make ice cream.
How long does it take to make ice cream in the ICE-21 vs. ICE-30?
Both models churn ice cream in about 20 to 25 minutes, provided the bowl is fully frozen and your ingredients are well-chilled beforehand. The exact time depends on your recipe.
Which one is easier to clean?
They are equally easy to clean. The lids, paddles, and freezer bowls are all removable. They should be washed by hand with warm, soapy water, they are not dishwasher safe.
Can you make back-to-back batches of ice cream?
No, not with a single bowl. Once you've made a batch, the bowl will have thawed and must be thoroughly washed, dried, and returned to the freezer for another 12-24 hours. To make consecutive batches, you'll need to purchase a second freezer bowl for your model.
Which model is a better value?
Both offer great value. The ICE-21 is a better value for individuals or couples who just need a basic, reliable machine. The ICE-30BC offers better value for families, as the small increase in price buys a significant increase in capacity.
Do they have the same dimensions?
Surprisingly, yes. The housing units of both the ICE-21 and the ICE-30BC have a very similar footprint, meaning they take up the same amount of counter space. The difference is in the size of the removable freezer bowl itself.
How loud are these ice cream makers?
Both models generate a noticeable motor noise during churning, similar to a stand mixer on a low speed. It's not silent, but it is generally considered within an acceptable range for a kitchen appliance running for 20 minutes.
