The Cuisinart Ice-21 and the Ninja Creami are two of the most popular at-home frozen dessert makers, but they operate on completely different principles. The Cuisinart is a traditional ice cream maker that churns a liquid base in a pre-frozen bowl, while the Ninja is a high-tech processor that shaves and blends an already frozen solid base into a creamy treat. This core difference impacts everything from price and versatility to prep time and final texture.
Here's everything you need to know to choose the right machine from Cuisinart or Ninja for your kitchen.
Cuisinart ICE-21 Frozen Yogurt - Ice Cream & Sorbet Maker
The Cuisinart Ice-21 is a classic, no-fuss ice cream maker known for its simplicity, reliability, and affordable price tag. It uses the traditional freezer-bowl method: you freeze the double-insulated bowl for 16-24 hours, add your chilled ingredients, and let the machine churn for about 20 minutes. It's an approachable and consistent machine for anyone who wants to make traditional ice cream and sorbet without a complicated setup.
- What it is: A single-function ice cream, sorbet, and frozen yogurt machine that uses a pre-frozen churning bowl.
- Key features: 1.5-quart capacity, double-insulated freezer bowl, built-in mixing paddle, and an easy-lock transparent lid with a large spout for adding mix-ins.
- Price: Typically $50 to $70.
- Style: Classic and functional with a simple, clean design. It comes in a few colors but is most recognized in its standard white finish.
- Materials/Construction: It has a durable plastic housing, a freezer-safe metal interior bowl, and sturdy moving parts.
- Pros: Extremely affordable, very easy to use (literally one on/off switch), makes excellent classic-style ice cream, the 1.5-quart capacity is great for families, and it's relatively quiet during operation.
- Cons: Requires significant pre-planning (the bowl must be frozen for at least 16 hours), you can only make one batch at a time until the bowl is refrozen, and its function is limited to churning traditional fresh ice cream bases.
This machine is ideal for anyone who wants to make classic frozen desserts on a budget and values simplicity and reliability over bells and whistles.

Ninja CREAMI Ice Cream Maker
The Ninja Creami is a completely different kind of frozen dessert appliance. Instead of churning liquid, it transforms a solid-frozen base into a creamy dessert in minutes using a high-powered blade system. You freeze your ingredients in one of the provided "pints," and when you're ready, the machine's "Creamerizer™ Paddle" shaves and blends the frozen block into an incredibly smooth and uniform texture suitable for ice cream, gelato, sorbet, milkshakes, and more.
- What it is: A multi-function frozen dessert maker that processes frozen bases into various treats like ice cream, gelato, sorbet, smoothie bowls, and milkshakes.
- Key features: Multiple one-touch programs, includes two or more freezer-safe pints with storage lids, a "Re-Spin" function for even smoother results, and a Mix-in function.
- Price: Usually between $200 and $250.
- Style: Modern, sleek, and vertically oriented with a black and silver finish that fits into contemporary kitchens.
- Materials/Construction: Built with high-quality, BPA-free plastics and a robust metal blade and motor assembly designed for high-speed processing.
- Pros: Extremely versatile with seven or more preset functions, create exceptionally smooth and creamy textures, ability to make multiple flavors in advance with extra pints, and it processes bases in under 3 minutes.
- Cons: Much more expensive, very loud during operation (similar to a high-powered blender), smaller individual batch size (1 pint), and still requires 24 hours to freeze the base solid.
The Creami is suited for a creative home user who wants to experiment with a wide variety of frozen desserts and prioritizes texture and multi-functionality.

Cuisinart Ice 21 vs. Ninja Creami Comparison
How They Work: Churning vs. Shaving
The most important distinction is the process. The Cuisinart Ice-21 follows a traditional method: its pre-frozen bowl contains a cooling liquid between the walls. As the paddle churns your liquid ice cream base, ice crystals form on the cold surface and are constantly scraped off and mixed back in. This slow churning and freezing process introduces air, creating a classic, lighter ice cream texture.
The Ninja Creami flips this concept. You freeze ingredients into a solid block. Then, a powerful motor drives a special paddle to spin and descend, effectively shaving a micro-thin layer of the frozen block. This high-speed shaving and blending process breaks down ice crystals into incredibly small particles, resulting in a dense, uniform, and exceptionally smooth texture.
Ease of Use & Preparation
Both machines require 24 hours of pre-freezing, which is a critical step for both. However, the workflow differs. With the Cuisinart, you freeze the one large bowl, limiting you to one flavor per 24-hour cycle unless you purchase an extra freezer bowl. The churning itself takes about 20 minutes and is relatively quiet.
With the Ninja, you can prepare and freeze multiple pint containers at once, allowing you to have different flavors ready to go. Once the pints are frozen, the "creamifying" process is very fast, taking only about two to three minutes. The major tradeoff is noise, the Ninja Creami is significantly louder than the gentle churn of the Cuisinart.
Capacity & Batch Size
Capacity is a clear delineator. The Cuisinart Ice-21 makes a 1.5-quart (6 cups) batch, which is perfect for serving a family of four to six people a fresh dessert. It's made for creating a single, larger batch in one go.
The Ninja Creami uses smaller 1-pint (2 cups) containers. While this seems smaller, its strength lies in variety. You can easily make three different flavors in three separate pints from one recipe. This is better for smaller households, individuals, or people who want a personalized dessert experience instead of one big batch.
Texture & Results
The final texture is a matter of personal preference. The Cuisinart produces a traditional, soft-serve style ice cream that is light and airy right out of the machine. For a firmer, scoopable consistency, it needs another hour or two in the freezer.
The Ninja Creami is known for producing an exceptionally dense and smooth result, similar to high-end gelato or premium ice cream. Because it pulverizes ice crystals, the final product is rarely icy. Its "Re-Spin" function allows you to process it a second time if the first spin comes out a bit crumbly, guaranteeing a creamy result.
Price & Value
At around $70, the Cuisinart Ice-21 provides excellent value. It does its one job - making great traditional ice cream - extremely well for a fraction of the cost of other machines. It's a fantastic entry-level appliance.
The Ninja Creami, at over $200, is a serious investment. Its value lies not just in making ice cream but in its versatility. If you plan to make sorbets, smoothie bowls, and gelatos regularly, it effectively replaces multiple appliances and justifies its higher price tag for enthusiastic users.
Which One Should You Choose?
Both of these machines are excellent at what they do, but they are built for fundamentally different users and kitchens.
Choose the Cuisinart Ice-21 if:
- You're working with a budget under $100.
- You want to primarily make classic-style ice cream, frozen yogurt, or simple sorbets.
- You prefer to make larger, family-sized batches (up to 1.5 quarts).
- You value simplicity, ease of use, and quiet operation above all else.
Choose the Ninja Creami if:
- You have a more flexible budget and want a multi-purpose dessert maker.
- You love experimenting with different textures like gelato, sorbet, and smoothie bowls.
- You want to prepare multiple different flavors in advance.
- You care deeply about achieving an ultra-smooth, dense, premium texture.
Frequently Asked Questions
What's the main difference between the Cuisinart Ice-21 and Ninja Creami?
The main difference is their method. The Cuisinart Ice-21 is a traditional machine that churns liquid ingredients inside a frozen bowl to freeze them. The Ninja Creami uses a powerful blade to shave and blend a pre-frozen solid base into a creamy consistency.
Which ice cream maker is better for a beginner?
The Cuisinart Ice-21 is more straightforward for beginners. Its one-switch operation and simple process make it less intimidating than the Ninja Creami's multiple buttons and settings.
Do I have to freeze the bowl or the pints beforehand?
Yes, both machines require a pre-freezing step of at least 16-24 hours. The Cuisinart needs its freezer bowl frozen, while the Ninja requires the ingredient base inside the pint to be frozen solid.
Which machine is faster?
While both require a 24-hour freezing prep time, the actual processing time is faster on the Ninja Creami, taking only 2-3 minutes. The Cuisinart takes about 20 minutes to churn.
Is the Ninja Creami really that loud?
Yes. The sound is often compared to a powerful blender. It's brief but very loud. The Cuisinart Ice-21 is much quieter, producing a low hum during its 20-minute cycle.
Which one is easier to clean?
Both are relatively easy to clean. The Cuisinart has a freezer bowl, paddle, and lid that need hand washing. The Ninja's pints, lids, and blade assembly are all top-rack dishwasher safe, giving it a slight edge in convenience.
Can I make healthy or diet-specific recipes in these?
While you can use healthy ingredients in both, the Ninja Creami excels here. Its powerful processing can turn simple frozen fruit, protein shakes, or non-dairy milks into desserts with incredible texture without needing high-fat or high-sugar bases.
Which machine takes up more space?
The Cuisinart Ice-21 has a bigger footprint on the counter during use, being wider and more square. The Ninja Creami is taller and more slender, taking up less counter space but requiring more vertical clearance, so check your under-cabinet height.
