Quick answer
Blend 1 1/2 cups cottage cheese with 1/2 cup milk, key lime juice and zest, sweetener and vanilla for 60 to 90 seconds until smooth, freeze the pint for a full 24 hours, then spin on Ice Cream, re-spin once with a tablespoon of milk if crumbly, and run Mix-in with 1 crushed graham cracker sheet. The pint carries roughly 41 g of protein, about 10 g per serving across 4 servings.
Key Lime Pie Ninja Creami Protein Ice Cream is the tart, creamy pint that tastes like the pie. It is cottage cheese, milk, key lime juice and zest, sweetener and vanilla, blended smooth, frozen solid, spun creamy and finished with crushed graham cracker folded through. Tart, creamy and properly high protein at the same time.
Why you’ll love it
- Tastes like real key lime pie, not like a protein shake that got frozen.
- About 10 g of protein per serving from label values, about 41 g per pint.
- Five minutes of hands-on work, then the freezer and the machine do the rest.
- No protein powder needed, since cottage cheese carries the protein here.
- Graham crumbs folded through give a real pie base crunch.
Ingredient notes
Key lime juice: a third of a cup, bottled or fresh. Bottled key lime juice is the weeknight shortcut and honestly hard to tell from fresh in a frozen pint, so save fresh limes for the zest.
Lime zest: two teaspoons, fresh only. Fresh zest gives a bright aroma that bottled juice alone cannot match, and it is what makes the flavor read as key lime instead of generic lime.
Cottage cheese: full-fat gives the creamiest result. Low-fat works too and keeps the protein high, but the pint freezes a little firmer. Small curd or large curd does not matter, since everything gets blended smooth for a full 60 to 90 seconds.
Sweetener: four tablespoons, a touch more than most pints here, because key lime needs sweetness to balance its tartness. Granulated sweetener or sugar both work at the same amount.
Graham cracker: one crushed sheet through the Mix-in cycle gives the pie base note. Use a gluten-free cracker if gluten matters to you, since the rest of the pint is naturally gluten-free.
The freeze and spin rule that makes or breaks it
Two rules decide this pint, and both are about patience. First, freeze for a full 24 hours on a level surface, with the top smoothed flat. A pint frozen for only a few hours, or frozen at a slant, spins soft and uneven. Second, do not judge the first spin. Cottage cheese bases often look crumbly after the first cycle, and that crumbly look sends a lot of people to the conclusion that the recipe failed. It did not. One tablespoon of milk and one re-spin turns it thick, creamy and scoopable. Only after the re-spin does the graham cracker go in, through the Mix-in cycle, so it stays crunchy instead of dissolving.
Variations
- Coconut key lime: add 2 tablespoons of shredded coconut through the Mix-in cycle along with the graham cracker for a coconut key lime pie pint.
- Key lime swirl: after spinning, fold in a spoonful of lime curd with a spoon, just twice, so it ripples through instead of blending away.
- Whipped top: finish each bowl with a spoonful of whipped cream and extra lime zest for a classic pie serving.
- Lemon lime: swap half the key lime juice for lemon juice for a brighter citrus pint that still reads as pie.
What we learned testing it
- Bottled key lime juice matched fresh juice closely in the frozen pint. Fresh juice won only on zest, where fresh lime zest gave a brighter aroma than bottled juice alone.
- Tartness level landed at 1/3 cup of juice. Less juice tasted muted after freezing, while more juice turned the pint sharp even after the freeze rounded it.
- The re-spin mattered as usual. The first spin looked crumbly, and one re-spin with a tablespoon of milk turned the pint thick and scoopable.

Blender · Ninja Creami machine · Ninja Creami pint container with lid
Instructions
-
Blend the key lime base until completely smooth
Add the cottage cheese, milk, key lime juice and zest, sweetener and vanilla to a blender, leaving the crushed graham cracker aside for later. Blend for 60 to 90 seconds until completely smooth, scraping down once, with no curd texture left. The base should taste a touch too tart, since freezing will round it out.
-
Pour into the pint and freeze for 24 hours
Pour the base into your Ninja Creami pint container, staying below the max fill line. Smooth the top with a spoon so it freezes level, which helps the machine spin evenly. Snap on the lid and freeze the pint on a level surface for a full 24 hours. A shorter freeze gives a soft, slushy spin.
-
Spin on Ice Cream, then re-spin if crumbly
Take the pint straight from the freezer, remove the lid and load it into the machine. Select the Ice Cream setting and let it run the full cycle. If the pint looks powdery or crumbly after the first spin, add 1 tablespoon of milk and press Re-spin. That one re-spin is what turns this base from crumbly to creamy.
-
Mix in the graham cracker and serve right away
Make a small well in the center of the spun pint with a spoon, drop in the crushed graham cracker and run the Mix-in cycle. The crumbs stay crunchy and give a pie base note in every few spoonfuls. Scoop into bowls right away, while the texture is at its best.
Notes
- Bottled key lime juice is the weeknight shortcut and honestly hard to tell from fresh in a frozen pint. Save fresh limes for the zest, where fresh makes a real difference.
- The base should taste a touch too tart before freezing. Freezing rounds tartness out, so a base that tastes just right liquid will taste muted once spun.
- Use a gluten-free graham cracker if gluten matters to you. The rest of the pint is naturally gluten-free, so the cracker is the only swap needed.
- If your freezer runs very cold and the pint is too firm to load, let it rest on the counter for 2 to 3 minutes before spinning, no longer.
Nutrition per serving
Nutrition information is being calculated.
Substitutions
- Key lime juice
- Use regular lime juice at the same amount. The flavor is slightly less floral than key lime, but the tart creamy balance stays the same.
- Graham cracker
- Use crushed vanilla wafers or shortbread instead for a different pie base note, or skip the mix-in entirely for a smooth key lime pint.
- Cottage cheese
- Use the same amount of blended Greek yogurt for a tangier pint with a similar protein count and a slightly softer texture.
Storage and make-ahead
The texture is at its best in the first few minutes after spinning. If you have leftovers, smooth the surface flat, put the lid back on and refreeze. Re-spin leftovers straight from the freezer on Ice Cream, adding a tablespoon of milk if they look crumbly. Eat refrozen leftovers within 3 days for the best texture.
Frequently asked questions
Can I use regular limes instead of key limes?
Yes. Regular lime juice at the same amount gives a slightly less floral flavor, but the tart creamy balance stays the same. Save fresh limes for the zest either way.
Can I use bottled key lime juice?
Yes. Bottled key lime juice is hard to tell from fresh in a frozen pint. Use fresh limes for the zest, where fresh makes a real difference.
Why does my key lime pint taste muted?
Freezing rounds tartness out. The base should taste a touch too tart before freezing, so a base that tastes just right liquid will taste muted once spun.
How much protein is in this ice cream?
These are label-based estimates, not lab tested numbers, and they vary by brand. The pint carries roughly 41 g of protein in total, about 10 g per serving across 4 servings. Check your cottage cheese labels for your exact numbers.
Can I refreeze and re-spin the leftovers?
Yes. Smooth the surface flat, lid the pint and refreeze it. Spin leftovers straight from the freezer on Ice Cream, with a tablespoon of milk if they look crumbly. The texture is best within 3 days.
