1-First Step: Mix the base Start by adding the key lime pie Greek yogurt, whole milk, vanilla protein powder, and lime juice to an ice cream maker pint container. Use a whisk, immersion blender, or frother to mix until the base looks smooth and slightly frothy. This part matters because a well-mixed base freezes more evenly and gives you a better final texture. Try to scrape the sides and bottom of the container so no dry protein powder is left behind. If you see a few small lumps, blend a little longer. The goal is a creamy mixture that looks uniform before freezing.

2-Second Step: Freeze the pint Put the lid on the container and freeze it for at least 8 to 10 hours, or overnight if that is easier. The mixture needs time to set fully before it goes into the machine. If the pint is under-frozen, the texture can turn slushy or uneven. For the best results, place the pint on a level shelf in the freezer. Do not overfill the container, and if you are using a different yogurt container size, adjust the ingredient amounts accordingly. This recipe was made for a Ninja Creami style pint, and it has not been tested with other ice cream makers.

3-Third Step: Spin it in the machine When you are ready to serve, take the pint out of the freezer. If you have time, let it sit for 5 to 10 minutes before spinning. That short rest can help reduce crumbliness. Remove the lid, place the pint into the machine, secure the blade lid, and process it on the lite ice cream setting. The first spin may look dry or crumbly, especially if the mixture is very cold. That is normal. The Ninja Creami often needs a re-spin to turn the frozen base into a softer, creamier dessert.

4-Fourth Step: Fix the texture if needed If the ice cream comes out crumbly, add a small splash of milk or a spoonful of yogurt, then use the re-spin function. This usually brings the texture together quickly. If you want a thicker result, add only a little liquid at a time so you do not make it too soft. Best texture tip: Whole milk gives the creamiest finish, and a high-quality vanilla protein powder makes a big difference in both flavor and smoothness.

5-Fifth Step: Add mix-ins for more flavor For extra texture, make a hole in the center after the first spin. Add your mix-ins, such as gluten-free graham cracker crumbs, white chocolate chips, or frozen cream cheese chunks, then run the mix-ins setting. The graham crumbs give you that pie crust feel, while cream cheese chunks add a cheesecake twist. You can also keep it simple and skip the mix-ins if you want a cleaner lime flavor. Either way, the dessert should look creamy, pale, and spoonable once finished.

6-Final Step: Serve and enjoy Serve the Ninja Creami Key Lime Pie plain or top it with whipped cream and graham cracker crumbs. Fresh whipped cream gives a light finish, while store-bought whipped cream saves time. This recipe makes 2 servings, so it works well as a shared dessert or a personal treat with leftovers saved for later.
