Buy spare pints. Skip almost everything else. The CREAMi has one real limitation — one container per spin, and the container has to be frozen overnight — and spare pints are the only accessory that meaningfully addresses it, for a fraction of what a second machine or a bigger model costs.
Why pints are the upgrade
With the two pints in the box, your realistic pattern is: prepare a pint, freeze overnight, spin it, wash it, prepare it again. That is one dessert a night and a washing-up step in the loop.
With six pints, the pattern changes completely: prepare four or five at once on a Sunday, freeze them all, and spin one whenever you want it for the rest of the week. The machine goes from an appointment to an on-demand appliance. That is the single biggest quality-of-life change available to a CREAMi owner and it is not a new machine.
Check compatibility before you order
Ninja lists its standard 16-ounce pints as compatible with the NC299AMZ, NC300 and NC350 series. The NC501 Deluxe uses 24-ounce XL tubs, which are a different part and are not interchangeable. Buying the wrong size is the most common accessory mistake here, and the listings do not always make the distinction obvious.
Why colored lids matter more than they sound
Ninja's four-pack ships with color-coded lids. This reads like a gimmick and is genuinely useful once you have five identical pints of pale frozen matter in a freezer: chocolate, coffee, protein vanilla and mango all look the same when solid.
If you end up with plain lids, a strip of tape and a marker does the same job. The point is that any multi-pint workflow needs labeling, because a frozen pint tells you nothing about its contents.
How many pints do you actually need?
Count the desserts you want available at once, then add one for the pint currently being washed. For one person eating three or four times a week, six total is comfortable. For two people eating most days, eight.
The real constraint is not money, it is freezer space. Six pints of base is six pints of freezer volume permanently committed. That is the honest hidden cost of the CREAMi workflow, and it is worth checking you have the room before you order two four-packs.
What is not worth buying
Replacement paddles, unless yours is damaged. The Creamerizer paddle is a wear part in principle, but it is not a consumable. Buy one when the original fails, not preemptively.
Third-party pints of uncertain fit. The pint has to seat correctly in the outer bowl for the machine to run, and a pint that does not seat is a pint you cannot use. The saving is small and the failure mode is total.
Storage lids sold separately from pints. The pints come with lids. Buying lids alone only makes sense if you have lost some.
“Recipe” bundles. The recipe ecosystem around this machine is enormous and free. Start with CREAMi vanilla and CREAMi protein ice cream.
Making the pint workflow work
- Freeze flat and level. The blade cuts down through the center of the block, so an angled or domed freeze spins unevenly. A level shelf is not optional.
- Fill to the max line, not above. Overfilled pints make the motor labor and can jam the blade.
- Label everything. Contents and the date. Frozen bases keep well but they are not immortal.
- Keep mix-ins out of the freeze. Add them with the Mix-in program after the main spin rather than freezing chunks into the block.
The mechanism behind all four rules is explained in how the Creami actually works, and if something has already gone wrong, the downsides page diagnoses it.
The short answer
One four-pack of the correct pints for your model, colored lids, and nothing else. If you are eyeing the Deluxe purely for capacity, spare pints on an NC301 is the cheaper and more freezer-efficient configuration — the reasoning is in the Deluxe review.
