How to make a Skinny Shamrock Shake

Did you know you can use bananas to make one ingredient ice cream?

We decided to use that concept to make our favorite holiday treat.

Instead of adding in green food coloring, I wanted to keep this recipe wholesome.

I added in spinach leaves.

WAIT.. WAIT.. Don’t go. I only added in about 3 leaves to achieve the light green color. You can add more if you want.

You could also add green food coloring. But I promise, 3 spinach leaves did NOT alter the taste at all!! The mint outshined everything!

  1. I’m in love. . .with this shake. I love that you can take frozen bananas and transform them into an ice cream-like treat. I cannot wait to try and fool my family with this trick. Brilliant!

  2. I may have to give this a try… I used to love McD’s Shamrock Shakes too…now they taste way too chemical-minty. Blehyeuch.

    However, Arby’s mint shake is great and reminiscent of what a McD’s used to be, and they use Andes mints. Although, if it’s the lactose that causes issues…stick with your version. =)

  3. I made this today and I felt it was way too much peppermint. The consistency was great. Next time I will add less peppermint and see how thst works out.

  4. Ok so I never liked them but my mom freaking loves those shakes, and I’m going to have to show her this recipe when I visit next week for sure! 😀 Thanks Aimee!

  5. This sounds insanely good! And perfect for right now that we’re trying to stick to a diet. I wouldn’t feel guilty with this at all unlike a McD’s shake. Great idea with the frozen bananas and the spinach for color.

    I’ve never had a shamrock shake so I wouldn’t know what I’ll be missing. Also, I don’t judge you at all for planning that peace and quiet. Honestly, I freaking bow to you! Breaking your peace time down to almost a science. I’m jelly.

  6. Crazy – I just made this yesterday! And I didn’t know you had this live – I’m going to try the mint and chocolate chip addition today. It sounds incredible!

  7. YESSS! GENIUS!!!! My mom loves those shamrock shakes like…A LOT! so I should make her these and AFTER

    1. (OMG I AM TYPING WAY TOO QUICKLY! I hit the enter key again!)

      I was saaaaying…after she tastes and falls in love. THEN I’ll tell her it’s healthy. hoooray!

  8. I must have this shake in my life! I love how you added frozen bananas…awesome idea. I’ll cut you slack that there’s spinach in there, seeing that it’s only 4 or 5 leaves. 😉 Definitely a must try! 🙂

  9. Well you are clever girl. turning the shamrock shakes into something skinny! Now I can drink several right?

  10. Awesome adjustments to make a healthier version. I love it! And I won’t argue one bit on the chocolate chips!

  11. I am loving the sneaky addition of spinach to give it that minty green look! And of course the chocolate chips are never optional…never!!!!

  12. I would never guess that it’s spinach that gave you the green color! And I love that banana ice cream trick – so tasty! I definitely want to make this. Great idea Aimee!

  13. Love this combo! I used to drop my oldest off and circle with a coffee, just until my youngest fell asleep 🙂

  14. I love the sound of this skinny shamrock shake! I can’t wait to try making this – way to go with the spinach leaves – such a sneaky and healthy addition in here 🙂 Pinning!

  15. Oh my gosh!!! You are so sneaky with you banana and spinach! I think the ladies in my weight watcher group might freak out about this recipe! I haven’t had a McDonalds shake is SO long, and when I busted my front tooth I decided to stop and get a soft serve. Now I crave it and I am worried that I won’t be able to hold out. Love this version of the Shamrock Shake!

  16. Gasp! These sound so good and I love that they are healthy! P.S. If you use dark chocolate chips, they are good for you, so pile them on! 😉

  17. I have tried over and over the frozen bananas blended and try to eat it plan. Let’s just say it did work out between us. BUT you added milk and vanilla and some other goodies, so I think I will give it another go and see how it turns out!

    1. It is very very thick for sure. I don’t think alone it tastes anything like ice cream (you can’t fool me), but with the milk and the mint it really is tasty! Maybe more like a smoothie?

  18. Umm…yes. I need this daily until St. Patty’s Day. And then every day after too. 🙂

    Thanks for the link love! <3
