What You’ll Need
- 1 cup 2% milk
- 3/4 cup plain nonfat Greek yogurt
- 1 scoop (about 30 grams) vanilla protein powder
- 2 tablespoons fresh lime juice
- 1 teaspoon finely grated lime zest
- 2 tablespoons sugar-free instant vanilla pudding mix

- 1/2 teaspoon vanilla extract

- 2 tablespoons finely crushed graham crackers
- 1 teaspoon finely grated lime zest, for topping

Recipe and Instructions
Step 1: Mix the Creamy Base
Pour 1 cup 2% milk into the Ninja Creami pint. Add 3/4 cup plain nonfat Greek yogurt, 1 scoop (about 30 grams) vanilla protein powder, 2 tablespoons sugar-free instant vanilla pudding mix, 1 tablespoon maple syrup, 1/2 teaspoon vanilla extract, and 1 small pinch salt.
Whisk well for about 45 to 60 seconds. Keep whisking until the yogurt, pudding mix, and protein powder are fully blended. Scrape around the bottom and sides if you see any dry powder.
Step 2: Add the Lime
Add 2 tablespoons fresh lime juice and 1 teaspoon finely grated lime zest to the creamy mixture.
Whisk for another 20 to 30 seconds. The base should look smooth and evenly mixed. Taste a tiny spoonful. It should be a little stronger and sweeter than you want the finished ice cream because freezing will soften the flavors.
Step 3: Freeze the Pint
Smooth the top of the mixture so it is level. Put the lid on the Ninja Creami pint.
Place the pint upright on a flat surface in your freezer. Freeze for at least 24 hours. It needs to be frozen completely solid before you process it.
Step 4: Spin the Ice Cream
After 24 hours, remove the lid. Put the frozen pint into the Ninja Creami outer bowl and lock it into the machine according to your machine’s directions.
Select Lite Ice Cream and let the cycle finish.
The first spin may look slightly powdery or crumbly. That is normal with many high-protein Creami recipes.
Step 5: Re-Spin Until Creamy
If the ice cream looks crumbly, run Re-Spin once.
Check the texture. It should now be thick and creamy. If it is still dry, add 1 tablespoon of 2% milk and Re-Spin one more time. Only add the extra milk if needed.
Step 6: Add the Key Lime Pie Finish
Spoon the finished ice cream into a round serving bowl.
Sprinkle 2 tablespoons finely crushed graham crackers over the ice cream. Finish with 1 teaspoon finely grated lime zest and 1 thin lime slice.
Serve right away while it is thick and creamy.
Why This Recipe Works (Quick Science)
The Ninja Creami works differently from a regular ice cream maker. Instead of churning a liquid while it freezes, it processes a base that is already frozen solid.
Greek yogurt adds protein and body. It helps give the ice cream a thicker feel.
Protein powder adds more protein, but too much can make frozen desserts chalky or dry. One scoop gives this pint a good balance.
Pudding mix contains starches and other ingredients that help thicken the base and improve its texture.
Milk provides the water, milk proteins, and a little fat needed for a smoother base.
Maple syrup does more than add sweetness. Sugar also helps reduce the hard, icy texture that can happen when a dessert freezes.
Finally, the Re-Spin breaks down the frozen base even more. That’s why a pint that looks powdery after its first spin can become surprisingly creamy after another cycle.
Pro Tips
- Freeze it flat. A level frozen surface is best for the Creami.
- Don’t overdo the lime juice. Extra juice sounds tempting, but too much can make the dairy base less creamy.
- Use fresh zest. Most of the strong lime aroma comes from the zest.
- Wait to add the graham crackers. They stay much crunchier when added just before serving.
- Don’t add lots of milk before a Re-Spin. Start with no extra liquid. If needed, add only about 1 tablespoon.

Substitutions and Variations
- Key limes: Use fresh key lime juice and zest instead of regular lime for an even more classic flavor.
- Milk: Fairlife or another ultra-filtered milk can increase the protein.
- Sweeter ice cream: Add a little more maple syrup or your favorite sweetener to the unfrozen base.
- More pie flavor: Add another tablespoon of graham cracker crumbs when serving.
- No graham crackers: Leave them off for a smoother dessert.
- Different protein powder: A vanilla whey/casein blend usually gives a creamy result. Plant protein can work, but the texture may be thicker or slightly grainier.
Make-Ahead Tips
This recipe is made for prepping ahead because the base needs a full 24-hour freeze.
You can mix several pints at the same time and keep them frozen with their lids on. Leave the graham crackers and fresh lime garnish off until you’re ready to process and serve each pint.
Common Mistakes
- Not freezing for a full 24 hours: The center may not be completely solid.
- Freezing the pint at an angle: Keep the pint upright on a flat freezer shelf.
- Adding too much protein powder: More protein powder does not always mean better ice cream. Too much can make it dry and chalky.
- Adding lots of milk for the Re-Spin: Too much liquid can quickly turn thick ice cream into a soft shake.
- Adding graham crackers before freezing: They can become soft instead of giving you that fresh pie-crust crunch.
- Skipping the zest: Lime juice adds tartness, but zest supplies much of that fresh lime aroma.
What to Serve With
This protein ice cream is filling enough on its own, but a few simple extras work well:
- Fresh strawberries
- Fresh raspberries
- Sliced banana
- Extra lime wedges
- Crushed graham crackers
- A small spoonful of whipped cream
- Toasted coconut
- Chopped macadamia nuts
Leftovers and Storage
If you have leftovers, smooth the remaining ice cream into an even layer inside the Creami pint and put the lid back on.
Store it in the freezer.
It will freeze hard again. When you’re ready for more, process the frozen leftovers with the Re-Spin function until creamy again. If they remain dry or crumbly, add about 1 tablespoon 2% milk and Re-Spin once more.
For the best texture and flavor, keep the graham cracker topping separate and add fresh crumbs after re-spinning.
FAQ
Q: Can I use bottled lime juice?
A: Yes, but fresh lime juice usually has a brighter flavor. You will still want fresh lime zest if possible.
Q: Do I have to use key limes?
A: No. Regular fresh limes work very well and are much easier to find.
Q: Why is my ice cream powdery after the first spin?
A: This can happen with low-fat and high-protein Creami recipes. Run a Re-Spin. If it is still dry, add about 1 tablespoon of milk and Re-Spin again.
Q: Can I leave out the pudding mix?
A: You can, but the ice cream may be a little icier and less creamy. The pudding mix helps thicken and stabilize the base.
Q: Can I double the recipe?
A: Make two separate pints rather than overfilling one Creami container. Always stay below your pint’s MAX FILL line.
Q: Can I add the graham crackers with the Mix-In setting?
A: Yes. If you want crumbs throughout the ice cream, make the ice cream creamy first, create a small hole in the center, add the crushed graham crackers, and run Mix-In. For the crunchiest texture, I prefer adding them on top.
Q: Why doesn’t frozen ice cream taste as sweet as the liquid base?
A: Very cold temperatures can make sweetness and other flavors seem weaker. That’s why the unfrozen mixture should taste a little stronger than you expect the finished ice cream to taste.
Final Thoughts
