Quick Recipe Breakdown
Prep & Freeze Time
- Prep Time: 5 minutes
- Freeze Time: 24 hours
- Total Time: 1 day, 5 minutes
What You’ll Need
- Ninja Creami Ice Cream Maker
- Blender (or a whisk if you’re old-school)
- Measuring cups and spoons
- A pint container
No Ninja Creami? You can use a regular ice cream maker—just note the texture might not be as creamy.
Ingredients
Here’s what you need to make this tart and sweet creation:
- 6 fl oz unsweetened almond milk (the base)
- 5.3 oz zero-sugar Key Lime Pie yogurt (the flavor star)
- 1 scoop unflavored whey protein powder (for protein power)
- 2 tbsp Swerve or any sugar substitute (for sweetness)
- 1½ tbsp lime juice (fresh is best!)
- 1 tsp vanilla bean paste (adds depth to the flavor)
- 4 drops green food coloring + 2 drops yellow (optional) (because pretty food is fun)
- ¼ tsp guar gum (for that luscious creamy texture)
- ½ graham cracker (broken into small pieces) (crust vibes, anyone?)
Optional:
- 1–2 tbsp almond milk (to adjust texture during re-spin)
Substitution Ideas
- Swap almond milk for oat, coconut, or regular milk if you want a creamier base.
- Can’t find Key Lime Pie yogurt? Plain Greek yogurt plus an extra dash of lime juice works just fine.
- Out of Swerve? Try Stevia, monk fruit, or even regular sugar.
Step-by-Step Instructions
Mix the Ingredients
Start by gathering all your ingredients. In a blender or mixing bowl, combine the almond milk, Key Lime Pie yogurt, unflavored whey protein powder, sugar substitute, lime juice, vanilla bean paste, and guar gum. If you’d like to add a pop of color, mix in a few drops of green and yellow food coloring too. Blend everything together until the mixture is smooth and lump-free. If you don’t have a blender, you can use a whisk for an equally effective method. Once blended, give it a quick taste test. If it’s too tart, add a bit more sweetener. If it’s not limey enough, squeeze in some extra lime juice. Adjust as needed to suit your flavor preferences.
Freeze the Mixture
Pour the smooth, blended mixture into a Ninja Creami pint container, making sure not to exceed the MAX FILL line. Place the container in your freezer on a flat surface and leave it uncovered to freeze. To achieve the ideal texture, it’s best to freeze the mixture for at least 24 hours. Be sure your freezer is set within a temperature range of -7°F to 9°F; this ensures the frozen yogurt sets just right.
Process in the Ninja Creami
Once the mixture has frozen solid, take it out of the freezer and place the pint container into the Ninja Creami’s outer bowl. Lock everything securely into the machine and select the “LITE ICE CREAM” setting. Let the Ninja Creami work its magic. If the texture looks crumbly or too dry after the first spin, don’t worry! Simply add a tablespoon or two of almond milk, create a small well in the center of the mixture, and re-spin. Repeat the process as needed until the yogurt achieves that perfectly smooth and creamy texture.
Add the Mix-ins
With your frozen yogurt perfectly spun, it’s time to add the finishing touch: graham cracker pieces! Use a spoon to carve a small hole in the center of the yogurt, where you’ll drop in the broken graham cracker pieces. Place the pint container back into the Ninja Creami and run the “MIX-IN” setting. This step will evenly distribute the graham cracker throughout the frozen yogurt. For an extra crunch, sprinkle a few graham cracker crumbs on top before serving.
Fun Variations
- Gluten-Free? Use GF graham crackers.
- Vegan? Swap out the yogurt and protein powder for plant-based options.
- Fancy It Up: Serve with whipped cream, a lime wedge, or a sprinkle of lime zest.
- Want a twist? Add a pinch of cayenne for a surprising kick.
Serving & Storage
- Serving Suggestion: Scoop into bowls or cones, and top with whipped cream, crushed graham crackers, or fruit.
- Leftovers: Keep your frozen yogurt in the pint container. Store for up to a week.
Re-spin leftovers before eating (don’t skip this step!) and let it sit at room temp for 5 minutes if it’s too hard.
That’s it—your homemade Key Lime Pie Protein Frozen Yogurt is ready to enjoy! Creamy, refreshing, and packed with flavor, this treat will make your taste buds do a happy dance. Try it out and let me know how it turned out!
