Ingredient Notes
Here are the ingredients you'll need to make your own shamrock shake protein ice cream:

- Milk—I like to use a combination of 2% milk and skim milk. This ensures the ice cream is creamy while keeping the calories low. You can use just one type of milk and it will turn out fine. Higher fat milk will yield a creamier texture. I also enjoy using a milk with increased protein, like Fairlife.
- Vanilla Protein Powder—I like to use the Premier Protein Whey Protein Powder in Vanilla Milkshake. It is creamy and provides 30g protein per serving, plus it doesn't have any weird flavours. Any vanilla protein powder you like will work.
- Spinach—This adds a ton of vitamins to the ice cream while naturally turning the base a bright green color. If you don't want to include spinach, you could use a few drops of green food coloring.
- Vanilla Extract—To enhance the flavor of the ice cream base.
- Peppermint Extract—I find pepper mint flavor emulates the taste of a McDonald's shamrock shake more than another mint extract like spearmint.
- Maple syrup—I find that this recipe needs a little extra sweetness to complement the peppermint flavor. You can use maple syrup, honey, or a sugar-free sweetener like Stevia.
- Optional lucky charms—I find a dollop of whipped cream and some lucky charms marshmallows are the perfect festive topping for this protein shamrock shake ice cream.
Substitutions
- Dairy-Free—You can use almond milk and plant-based vanilla protein powder to make the base dairy free. Note that the texture will likely not be as creamy.
- The Ninja Creami is also great for adding more mix ins like m&ms, chocolate chips, fruit chunks, cookie bits, peanut butter, etc. Blend on Lite Ice Cream first, Re-Spin if necessary, then add your mix-ins and blend on Mix-In.
- Food Coloring—This recipe uses fresh spinach to naturally dye the creami green for St. Patrick's Day. If you don't have spinach, you can use a few drops of green food dye.
Step-by-Step Instructions
Be sure to read the recipe card below for the full recipe and nutrition facts. Note that I have the Ninja Creami Deluxe model, as photographed below. I've scaled this recipe to also fit in the smaller original models.
(1) Add all ingredients except the lucky charms to the bucket of a high power blender. Blend until the spinach is pulverized.
Pour the mixture into a Ninja Creami pint container. Freeze overnight.
Run the pint under warm water for 30 seconds then dry it off. Place in the outer bowl.
(2) Blend on “Lite Ice Cream”, then add 1-2 tablespoon extra milk and “Re-spin” if necessary.
(3) Top with whipped cream and lucky charms if desired. Enjoy immediately!

Make Ahead
The base of this protein ice cream must be made ahead of time, as it needs to freeze for at least 12 hours. If you want to meal prep your protein ice cream, you can buy additional Ninja Creami pints for your machine on Amazon, then mix and freeze several pints at once to always have protein ice cream at the ready.
Storing Leftover Protein Ice Cream
This recipe makes a good dessert for 1-2 people. It's quite filling! Either scoop into two bowls, or enjoy straight from the pint.
Should you have leftover protein ice cream, smooth the top flat with a spoon, then place the pint cup back in the freezer. Blend on Lite Ice Cream the next time you want to enjoy it.
Tips and Tricks
Here are some of my top tips for perfect protein ice cream in the Ninja Creami :
- While I'm not sure 24 hours is truly necessary like Ninja suggests, the mixture must freeze for at least 12 hours before blending.
- A lot of recipes will call for a pinch of xanthan gum or instant pudding mix to help the texture and creaminess of low-fat protein ice creams. I find it adds too much of an unpleasant flavour, even in small quantities. Pudding mix can also be hard to find. I don't recommend it, nor do I think it needs it. Most protein powders have some thickeners already in them, and the Ninja Creami has a really powerful blade.
- Higher fat milk will make this protein ice cream even creamier.
- Use spinach for a natural green color.
- Top with whipped cream and lucky charms for a festive St. Patrick's Day treat!
- The Lite Ice Cream setting is meant for low fat mixtures like this protein ice cream. If you like your protein ice cream softer, you can Re-Spin a few times.
Frequently Asked Questions
This loosens the frozen sides and bottoms before blending to prevent an icy texture.
After the first spin, a lot of protein ice creams will have a powdery texture due to the low fat content. Just run a Re-Spin cycle or 2 until you have your desired texture.
You could try freezing the milk into cubes, then adding the other ingredients with a splash of extra milk and blending like a protein shake, but you won't get as thick of a texture as with the Ninja Creami. If you don't have a Ninja Creami, follow the recipe for my Protein Shamrock Shake, made in the blender.
