☘️ What is a Shamrock Shake?
A Shamrock Shake is a mint-flavored milkshake that is available during the month of March at select McDonald's locations. The original McDonald's Shamrock Shake contains vanilla soft-serve ice cream, cream, and mint-flavored syrup (high fructose corn syrup and green dye), then it is topped with whipped cream and often comes with a maraschino cherry. A small Shamrock Shake (McDonald's version) has 540 calories, 13 g of fat, 95 g of carbohydrates, and 72 g of sugar.
💗 Why you'll love this recipe
- This is a simple recipe that comes together in less than 5 minutes.
- Tastes just like the McDonald's version, or better.
- Even though it contains spinach and kiwi, it tastes like an ice-cream-based shake, making it kid-friendly.
- It has a refreshing peppermint flavor.
- It's naturally sweetened, with no added sugar or artificial sweeteners.
- You can enjoy this Shamrock flavor all year, not just during the shamrock shake season!
🍌 Ingredients and Substitutions
- Banana. I used a fresh ripe banana, but you could also use a frozen banana for an even creamier shake. This naturally sweetens the smoothie.
- Vanilla protein powder. This gives the smoothie a high protein content and delicious vanilla flavor. You could also use chocolate protein powder for a mint chocolate chip flavor.
- Spinach. I used fresh spinach, but you could also use frozen spinach. This gives the smoothie a lovely green color; you can't taste it!
- Almond milk. I used unsweetened almond milk, but you could use your favorite milk of choice.
- Peppermint extract. I used pure peppermint extract. Add an extra drop or two if you like a stronger mint flavor. Always start with a small amount the first time you make it, and add more if you like.

I make this but I use real mint leaves instead of the extract and I also add cucumber. everything else I used to the almond milk and the protein powder vanilla and spinach banana but I don't do the kiwi. if I want to get real creamy I put some avocado in there. it is addicting.
