1-First step: Mix the base Start by adding 2 cartons of key lime pie Greek yogurt, 1/2 cup whole milk, 1 scoop vanilla protein powder, and 2 teaspoons lime juice to a mixing bowl. Whisk everything together until the mixture looks smooth and fully combined. If your protein powder tends to clump, let it sit in the liquid for a minute before whisking again. For a dairy-free version, use full-fat coconut yogurt or coconut cream instead of the Greek yogurt, and replace the milk with a plant-based option. The mixture should still be thick, creamy, and pourable.

2-Second step: Taste and adjust Give the base a quick taste before freezing. If you want a sharper lime flavor, add a small splash more lime juice. If you want it sweeter, you can add a little sweetener, though the key lime pie yogurt already brings some sweetness. This is also a good moment to make sure the flavor is balanced before it gets frozen. If you are using a different yogurt flavor, like plain, lemon, or strawberry, this is where you can shape the flavor to match your goal. Lemon yogurt with lemon juice gives a bright citrus version, while strawberry yogurt makes a fruitier spin.

3-Third step: Pour into the Creami pint Carefully pour the mixture into your Ninja Creami pint. Do not go over the max fill line. If you want a little extra pie-style texture, you can stir in a small handful of gluten-free graham cracker crumbs before freezing, but many people like to add those after spinning for more crunch. Tap the pint gently on the counter to release any trapped air bubbles. This helps the mixture freeze more evenly and can improve the texture later.

4-Fourth step: Freeze until solid Place the pint on a flat surface in the freezer and freeze it for at least 24 hours. This part matters. A fully frozen base gives the machine the best chance of creating a smooth, creamy result. If the pint is still soft in the center, the final texture may turn icy or crumbly.

5-Fifth step: Spin in the Ninja Creami Once the base is frozen solid, place the pint in the machine and use the Lite Ice Cream or Ice Cream setting. If your model does not have Lite Ice Cream, the regular Ice Cream setting works well too. After the first spin, check the texture. If it looks powdery or dry, add 1 to 2 tablespoons of milk or oat milk, then respin.

6-Sixth step: Add mix-ins or toppings Once the texture looks right, make a small well in the center if you want to add toppings or mix-ins. Good options include whipped cream, gluten-free graham cracker crumbs, white chocolate chips, or frozen cream cheese chunks. If you want a stronger pie vibe, the graham cracker crumbs are a great choice. If you want a sweeter dessert, white chocolate chips work nicely. For a richer texture, frozen cream cheese chunks melt slightly into the mix and create little creamy bites throughout the pint.

7-Final step: Serve right away or firm up a little You can eat it right after spinning for a soft-serve texture. If you want a firmer scoop, pop the pint back in the freezer for 15 to 30 minutes. That makes it closer to traditional ice cream, which some people prefer. Spoon into bowls or enjoy straight from the pint if you are in a hurry.
