Ingredients in Shamrock Protein Shake (Ninja Creami)
Let’s take a look at what makes this minty shake so delicious and nutritious:
Base
- Vanilla or Plain Protein Shake/Drink: Your favorite ready-to-drink protein shake or a blend of protein powder + milk forms the base. Choose one with a smooth, creamy texture.
- Greek Yogurt (Optional): Adds extra creaminess and a boost of protein. Plain or vanilla both work great.
- Unsweetened Almond Milk or Milk of Choice: Helps adjust the consistency to your liking before spinning.
Flavor & Add-Ins
- Peppermint Extract: Just a drop or two gives you that classic Shamrock Shake minty flavor. A little goes a long way!
- Vanilla Extract: Adds warmth and enhances the overall flavor.
- Maple Syrup or Sweetener of Choice (Optional): If you want a bit more sweetness, this is your go-to.
- Green Food Coloring or Spinach: For that fun, festive green hue. Spinach keeps it natural without changing the flavor!
Optional Toppings
- Mini Chocolate Chips or Cacao Nibs: For a little crunch and a mint chocolate chip vibe.
- Whipped Cream: Totally optional, but fun if you want the full milkshake experience.
- Crushed Mint Candy or Peppermint Dust: For a little holiday sparkle on top.
Instructions
Here’s how to make this frosty green dream from start to finish:
Step 1: Blend the Base
In a blender, combine your protein shake (or protein powder + milk), Greek yogurt (if using), peppermint extract, vanilla extract, and sweetener. Add a few drops of green food coloring or a small handful of spinach to give it that signature Shamrock look. Blend until smooth.
Step 2: Freeze
Pour the mixture into your Ninja Creami pint container. Make sure not to fill past the max fill line. Place the lid on, and freeze for at least 24 hours until solid.
Step 3: Spin It
Once fully frozen, remove the pint from the freezer and install it in your Ninja Creami machine. Select the “Lite Ice Cream” or “Smoothie Bowl” function (depending on texture preference). If needed, add a tablespoon or two of milk and respin for a creamier texture.
Step 4: Add Toppings
Once spun to perfection, stir in or sprinkle your mini chocolate chips, cacao nibs, or any other fun toppings.
Step 5: Serve and Enjoy
Scoop into a glass or bowl, top with whipped cream if you’d like, and enjoy every cool, minty spoonful!
How to Serve Shamrock Protein Shake
Classic Milkshake Style: Pour it into a tall glass with a straw, top with whipped cream and a sprinkle of chocolate chips or crushed peppermint.
Smoothie Bowl: Serve in a bowl and add your favorite toppings—granola, nuts, or even a drizzle of nut butter for extra flavor and crunch.
Post-Workout Treat: Serve as-is for a protein-rich, recovery-friendly snack after hitting the gym.
Mini Dessert Cups: Pour into small ramekins or cups and freeze for a few hours for a firmer, scoopable dessert later.
Additional Tips
Adjust the Mint: Peppermint extract is powerful—a little goes a long way! Start small and taste-test if you’re adding it pre-freeze.
Boost the Protein: Add a scoop of your favorite protein powder if your base isn’t quite protein-packed enough.
Dairy-Free Friendly: Use dairy-free protein shakes, yogurt, and milk for a completely plant-based version.
Play with Textures: Stir in crushed cookies, chocolate shavings, or even a ribbon of almond butter before serving.
Make It Green Naturally: Spinach really is the magic trick here—it gives you the green without changing the taste. You’ll never know it’s there.
