Shamrock Shake

Confession, I’ve never had a shamrock shake from McDonald’s. But I love the idea of a green minty milkshake for St Patrick’s Day, so I set out to make my own, with a bit less fat and calories.

You can also freeze this into popsicles similar to these Avocado Coconut Pops. If your looking for more St Patrick’s Day festive recipesChocolate Stout Cupcakes with Bailey’s Irish Cream Cheese Frosting and these adorable St Patty’s Rainbow Cake Pops are a perfect treat for the occasion.

Yesterday I drove to three McDonald’s just to test them out, but no one seemed to carry them in my area, which surprised me since the commercials seem to be running frequently on my TV.

No worries, I figured I know what mint ice cream should taste like, I’m sure it’s not much different.

A lot of thought was put in on how I would make this sweet and creamy like a real ice cream shake. But, I didn’t want to add artificial green food coloring. I knew I was going to start with Stonyfield’s 0% fat vanilla frozen yogurt, because I just love it. I’m always amazed at how much it tastes like full fat vanilla ice cream. I also knew I would add a little spearmint extract to give it that minty flavor. But for the coloring, I was stumped. Then it hit me… avocado’s are green, creamy and taste great in smoothies, so it was the perfect solution.

In fact, I may drizzle a little chocolate syrup on top next time I make this to get that mint chocolate chip experience. This is a fun dessert your kids I bet will enjoy!

    My kids and I all loved it! I used 2 packets of Nectresse natural sweetener and it was absolutely perfect!

    What a great idea, thanks for posting this recipe I'm definitly going to give it a try 🙂

  4. Just curious if you had any idea how many of the fat grams come from the avocado alone? Those are the good fats to eat!

    I am drinking this now! I didn't have an avocado so I used spinach. And the yogurt I used was low-fat Dannon vanilla. It is surprisingly yummy! I only wish mine was thicker.

    Avocados always make their way into my smoothies. I'm not sure how it will change the calorie count (I don't really count those, I just like eating healthier), but I'm going to try it out this afternoon with my Mint Chocolate Chip Frozen Yogurt and omit the mint extract.
    McDonald's Shamrock Shakes are nowhere near as good as they were years ago. I'm excited about this recipe.

    My daughter gave in to 'advertizing' and had to try the Shamrock shake at McD.. it was creamy, but flat. It definitely wasn't worth the calories — empty calories. Green and creamy but not so great. I am glad you made one, much better for all!

  8. I think I am going to make this and add some cocoa nibs for a mint chocolate chip shake!
    I have some blended avocado in the freezer too. PERFECT!

    My husband is a HUGE ice cream and shake fan so we gave this a try tonight and we both LOVED it! This is certainly a make again for us. Thank you!

    Tried this tonight and it was fantastic! The mint extract is spot on. Peppermint is fine if you like it, but the mint extract is true to the flavor of a shamrock shake. Made this for hubby and a friend and it exceeded everyone's expectations. It is not even a sacrifice to have this over the fuller fat version. Everything I've made of yours is a winner. Thanks Gina!!

    This looks seriously delicious. Can't wait to try it. I have a weakness for ice cream, but always feel so guilty eating it.

  13. Definitely planning to try this! I never thought of Avocado! 😀 I was at McDonalds with my little guy today, contemplating the desire for a Shamrock shake and wisely turning away from temptation… THIS, I can really wrap my head (and lips) around. Thanks!!!

  14. This is magic… in a glass. No, seriously! Mint chocolate chip ice cream is my all time favorite and this is perfect! Creamy, minty goodness! Also, I do have to point out that having hunted down the suggested frozen yogurt I am now going to buy that when I want ice cream. You would never know it's not real full fat ice cream! Amazing!!

    1. You can grow chocolate mint as well as regular mint plants. Some of the leaves of that would be great in this!

    Apparently McDonald's uses broccoli to colour their Shamrock Shakes – I wonder if I would taste it in your version? Obviously I would have to juice/pulverize them to not get the texture LOL

    1. Vanilla Reduced Fat Ice Cream: Milk, sugar, cream, nonfat milk solids, corn syrup solids, mono- and diglycerides, guar gum, dextrose, sodium citrate, artificial vanilla flavor, sodium phosphate, carrageenan, disodium phosphate, cellulose gum, vitamin A palmitate.

      Shamrock Shake Syrup: High fructose corn syrup, corn syrup, water, sugar, natural flavor (plant source), xanthan gum, citric acid, sodium benzoate (preservative), yellow 5, blue 1.

      maybe the broccoli is the "plant source" natural flavor 😉

  16. I had a shamrock shake yesterday and regret it. It didn't really taste like anything other than sugar, not creamy, not minty, just so, so sweet. While I think it's funny to knock off something you haven't had, this is an innovative take and I might just try it!

    1. omg! I totally agree with all u said. I too had a shake a few days ago and it didn't taste like i remember it did yrs ago. I threw half out cuz all i tasted was pure sugar!! it was horrible!!

  17. Loved this! I didn't have any Stonyfield 0% so I used Haagen Daz low fat though. It was very creamy and you couldn't taste the avocado at all, it just made it a very nice green color. Will definitely be making this again when I'm craving something thick and creamy.
