Did you know you can use bananas to make one ingredient ice cream? We decided to use that concept to make copycat Shamrock Shakes, a seasonal favorite.
- No green food coloring!
- The perfect mint chip flavor.
- Naturally sweetened with bananas.
- Rich in calcium.
- Virtually fat free!
If you want a more classic shamrock shake, feel free to blend vanilla ice cream with mint and milk until creamy. Today’s version is just a healthy indulgence!
Ingredient Notes
For the mint milkshake base, you’ll need:
- Frozen bananas – Sweetens the shake and mimics the consistency of ice cream.
- Fat free milk – Or use 2% or whole milk if you’re not concerned about the calorie content.
- Peppermint extract – You need less than a teaspoon. It’s strong!
Most copycat shamrock milkshake recipes use artificial food dye for the light green color. I wanted to keep this recipe all-natural without compromising the familiar color of the original.
You won’t believe what I used.
Spinach leaves!
Before you panic and click away. . . I only added in about 3 leaves to achieve the light green color. It doesn’t give the shakes a spinach taste at all.
The mint outshines everything!
I topped the blended shakes with some fat free whipped cream and a handful of mini chocolate morsels, too.
Tips and Tricks
Skinny Shamrock Shakes take just minutes to blend together. Toss the ingredients in your blender and blend away!
- The amount of blending time you need depends on the strength of your equipment. Mine took about 5 minutes to reach the smooth, blended consistency I like.
- Make it dairy free by using your favorite nondairy milk. Plain or vanilla almond, soy and oat milk would all be delicious alternatives.
- For an even mintier treat, swap the spinach leaves for fresh mint leaves! Add as many as you like to achieve the perfect color.
- I used a blender to make these milkshakes. A food processor would work too.
- Like most milkshake recipes, you may need to scrape down the sides of the blender or processor bowl a few times to get everything combined.

Because I indulge in way to many of these I figured it was time to try a skinny version! Yum!
This is so good and easy to make! Totally irresistible!
This was super easy to make and turned out great! Love the addition of the spinach leaves…such a great idea!
A skinny shamrock shake sounds incredible but I won’t use peppermint extract, I’ll use spearmint. I haven’t had a shamrock shake that tasted like a candy cane yet. 😉 They’ve all had a mint ice cream flavour, which is spearmint.
Where is the sugar content? I am with WW and it calculates sugar also. Thanks!
this has great texture, but I would recommend less peppermint extract. It tastes kind of like toothpaste but would be really good with about 1/4 of the peppermint.
