What is a Shamrock Shake?
If you've never tried a traditional Shamrock Shake, it's a thick milkshake that has a sweet minty vanilla flavor. To achieve a similar flavor and texture I used a few simple ingredients like frozen bananas, vanilla protein powder, avocado, and a touch of peppermint extract.
This healthy Shamrock Shake recipe tastes similar to Mcdonald's version, but this recipe is lower in sugar, packed with protein, and nutrient dense. Plus, there's no artificial green food coloring or high fructose corn syrup!
I also added in a small handful of baby spinach to give it a vibrant green color! (I promise you can't taste it!) It's the perfect healthy treat to enjoy on St. Patrick's Day!
Why You'll Love This Recipe
I love protein shakes because they take about 5 minutes to make, and you can enjoy them as a quick breakfast, meal-replacement, or post-workout snack.
This delicious green smoothie will keep you full for hours thanks the protein and healthy fats! I love that it's blood sugar balancing and keeps me full for 4+ hours!
You can also easily double this recipe so you can share with your family!
🍴Ingredient Notes
- Vanilla Protein Powder - My favorite vanilla protein powders are Amy Meyers Paleo Vanilla Protein and Ancient Nutrition Vanilla Bone Broth Protein.
- Frozen Ripe Bananas - The greener the banana, the less sweet the smoothie will be. I recommend using ripe bananas for this recipe. For more information, check out my post on how to freeze bananas for smoothies!
- Cold Water - You can also use a non-dairy milk like unsweetened almond milk, coconut milk, or cashew milk. I've found that because of the creaminess from banana and avocado, water works great though!
- Ripe Avocado - The avocado adds a creamy texture to this smoothie.
- Peppermint Extract - My favorite organic peppermint extracts are the Thrive Market brand or Flavorganics which I found on Amazon.
- Ice - It's optional to add ice, but I like adding in a small handful to make it a little colder!
Recipe Variations
- Make it sweeter by adding in a tablespoon of maple syrup. You can also add in medjool dates, but keep in mind it will change the color of the smoothie.
- Swap the peppermint extract for a few fresh mint leaves.
- To make more of a traditional milkshake, try swapping the frozen bananas for dairy-free vanilla ice cream!
🍴Step by Step Instructions
Step 1: Add Ingredients into Blender
Start by adding all ingredients into a high-speed blender. Blend on high until smooth and creamy. Stop to scrape down edges as needed.
Step 2: Blend & Pour
Pour into a chilled glass and enjoy!
Expert Tips
- If your smoothie is too thin, add more frozen banana or ice for a super thick and creamy texture.
- If you don't like thick smoothies, add a little extra water or plant-based milk to thin it out.
- Freeze leftover smoothie in silicone ice cube trays to use for later!
- Use a high-speed blender for this recipe. If you only have a food processor on hand, you can use that too!
- Don't pour the peppermint extract into the measuring spoon over the blender just in case it spills! You only need a tiny amount to give it a mint flavor. Peppermint extract has a very strong flavor!
- Chill the cup in the freezer for 5-10 minutes before making the smoothie.
Serving Suggestions
This shake is delicious on its own, but you can also get creative with the toppings!
Stir in chocolate chips or cacao nibs to make a chocolate mint shake.
You can also garnish with green sprinkles or whipped cream and a maraschino cherry on top. Check out Homemade Coconut Whipped Cream recipe!
Before you pour the smoothie into a glass cup, drizzle dark chocolate around the inside! You can also add a chocolate drizzle to the top too!
How to store leftovers
Store leftovers in a glass cup with a lid like a mason jar in the refrigerator or freezer. (It will not stay as thick in the refrigerator.)
You can also make smoothie ice cubes by pouring leftovers into a silicone ice cube tray and freeze for later! (Or meal prep by doubling the recipe!)
Blend the frozen cubes with a non-dairy milk for a quick and easy smoothie.
