1-First Step: Mix the base In a pint container, combine the 2 cartons of key lime pie Greek yogurt, 1/2 cup milk, 1 scoop vanilla protein powder, and 2 teaspoons lime juice. Use a frother, immersion blender, or whisk to mix until the base is creamy and lump-free. This step is important because small lumps can freeze into hard bits later.

2-Second Step: Freeze overnight Once the mixture is smooth, put the lid on the pint container and freeze it upright for at least 10 hours. Overnight is best, and longer is fine too. The base needs to be fully solid so the Ninja Creami can process it into a smooth frozen dessert. For the best results, place the pint on a flat shelf in the freezer. Do not tilt it. A level freeze helps the machine spin evenly and keeps the final texture creamy.

3-Third Step: Let it rest before processing When you are ready to make your frozen treat, take the pint out of the freezer and let it sit at room temperature for 5 to 10 minutes. This little rest can keep you from having to re-spin the pint more than once. It helps soften the outside just enough for the blade to work through the base.

4-Fourth Step: Spin in the Ninja Creami Remove the lid and place the container into the ice cream machine. Process it using the lite ice cream setting. This is the best setting for a recipe like this because it gives you a smooth and creamy texture that works well with yogurt-based mixtures. After the first spin, check the texture. Some pints will look fluffy and ready right away, while others may seem crumbly. That is normal. Protein ice cream often needs a quick adjustment to get just right.

5-Fifth Step: Re-spin if needed If the mixture looks crumbly, add a splash of milk or yogurt and re-spin. Start with just a small splash because too much liquid can make the texture too soft. If you want a thicker finish, use a tiny bit of extra yogurt instead of more milk. This is also the point where you can add mix-ins. Graham cracker pieces or frozen cream cheese chunks work really well here. Add them after the first spin, then process again so they fold into the ice cream without disappearing.

6-Final Step: Add toppings and serve Scoop the finished Ninja Creami Key Lime Pie into bowls or eat it right from the pint. Top with whipped cream and graham cracker crumbs if desired. Those toppings give it that classic key lime pie feel and make the dessert look extra pretty for family dessert night or a quick after-school treat.
