Why I Love This Recipe
The first time I made this, I was trying to recreate the flavor of key lime pie in a lighter frozen dessert. I wasn’t sure if frozen yogurt would capture that classic tart citrus flavor, but after one spoonful, I knew it was a winner.
The yogurt brings a creamy texture, while the key lime juice adds that fresh, sunny flavor. The Ninja Creami transforms a simple frozen base into something that feels like it came from an ice cream shop.
What I love most:
- Bright, fresh key lime flavor
- Smooth and creamy texture
- Easy ingredients
- Less heavy than traditional ice cream
- Great make-ahead dessert
- Refreshing on warm days
- Tastes like frozen key lime pie
What You’ll Need
- 2 cups plain Greek yogurt
- ½ cup whole milk
- ⅓ cup sweetened condensed milk
- ¼ cup fresh key lime juice
- 1 teaspoon key lime zest
- 1 teaspoon vanilla extract
- Pinch of salt
Why This Recipe Works (Quick Science)
Greek yogurt contains protein that helps create a creamy texture when frozen. The sweetened condensed milk adds sugar, which lowers the freezing point and keeps the mixture from becoming rock hard. The fat from the milk and yogurt also helps create a smoother texture after spinning in the Ninja Creami. The lime juice brings acidity that balances the sweetness and makes the flavor taste brighter.

- Freeze the pint on a completely level surface.
