(Skinny) Thin Mint Shake

A skinny version of the famous girl scout cookie – thin mint in a shake version. You won’t be able to believe this is healthy!

A Skinny Thin Mint Shake from Chelsea's Messy Apron

Aaaaand I’m back to the current holiday at hand. Or I guess Girl Scout cookies aren’t really a holiday.

So nevermind. I guess I’m trying to say, I’m not posting Easter cupcakes today (obviously) and I’m back to “in season” foods. Namely the in-season food of GIRL SCOUT cookies.

Sorry sometimes I have to shout. I just get so excited about things. Namely food things. And more specifically girl scout COOKIE foods.

There, it happened again. Can’t help it guys, I can’t.

Thin Mint Healthy Shake - delicious!

Let’s just talk for a second about how excited I am about this shake. First off, it is honestly the yummiest “healthy” shake I’ve ever had. Promise.

And it is a “skinny” shake which makes it being delicious that much better.

The ingredient line-up: milk, a frozen banana, vanilla yogurt (I used low-fat), sugar-free chocolate pudding, truvia, peppermint extract, ice, xanthan gum, and 1 crushed up thin mint.

Skinny Thin Mint Shake

Okay, but let’s talk about a few things. Like if you don’t like bananas? I could not taste banana in this shake at all, honest. But it does give it a creamy thickness and helps everything to blend together. I freeze my bananas beforehand by peeling them, slicing them into coins, and then putting the coins on a cookie sheet (lined with parchment) to freeze. Once they are frozen on the cookie sheet, I transfer the frozen banana coins to a resealable bag ready for shakes to be made. This shake works best (and tastes best) with a very ripe frozen banana.

Next, xanthan gum. Have you heard of it? It’s amazing. Like changes a watery shake to the thickest creamiest drink ever. To be rivaled only by a DQ blizzard. I got mine at Wal-mart in the gluten-free section. It can be a little pricey, but if you use it for shakes, it will last a looooong time. A very tiny amount goes a long way. To get this shake to be really thick and creamy you are going to want to add some of the xanthan gum to it. I also added ice to increase the thickness and volume of the shake. You can adjust – more ice is thicker and less ice will create a thinner shake.

The yogurt and milk can be adjusted to your personal preference. I used unsweetened almond milk (30 calories for 1 cup), and a low-fat vanilla yogurt (90 calories) which is how the calorie amount was calculated. The sugar-free pudding gives this shake a rich chocolatey taste with a lot less calories. The truvia can be substituted for any sweetener you choose, but the calorie amount reflects zero for truvia since it doesn’t have any calories.

Which by the way, this shake – only 130 calories! Wa-bammmmm. And it tastes like ice cream. Well, almost.

Thin Mint Shake

Finally, peppermint extract. Like the xanthan gum, a little goes a long way as well. I didn’t want an overpowering taste, so I added a very small amount. You can add more if you want a stronger peppermint taste in your shake.

Oops, I almost forgot the garnish! I crushed up one thin mint on the top of the shake and swirled it around. This is of course optional, but a great touch to a “thin mint” shake! (P.S. The cookie isn’t calculated into the calories, but it would add 20 calories to each shake!)

    Missing Girl Scout Cookie season has been making me sad, but it’s probably a good thing (for my waistline at least!), and now I can indulge in the same delicious taste with this! It looks so delicious, and love that it’s skinny. Pinned!

  2. says

    Oh yum, I love think mints and this shake looks so good! Love that it’s skinny – it means I could totally have this for breakfast too :)

  3. says

    Sounds delicious! I wonder if different parts of the country have different girl scout cookie seasons? Because ours is long over :( This shake would be amazing even without the cookie garnish, though. Love the tip about xantham gum! Never would’ve tried that on my own.

  4. says

    I’ve never used xanthan gum but I always see it at the store. I’ll have to give it a try! I don’t like bananas (I know I’m weird! lol) but if you can’t really taste it then I’ll definitely give this a try!

  5. says

    I agree — shakes and smoothies need bananas for body — they’re such natural thickeners! I’ve used xanthum gum in gluten free baking, but never not to use it in a shake. I’m gonna have to give that a whirl!

  6. says

    I just love anything made with girl scout cookies. :) And gosh, I can’t believe how light you made this milkshake! I’ve never heard of xanthan gum or tried it, but it sounds totally worth it for this! Wishing I still had a box of Thin Mints left, haha. :)

  7. says

    haha I love that you used ALL CAPS. Sometime I just have to shout too :) This looks lovely dear. You’re crazy if you don’t love thin mints right?! Xantham gum sounds super interesting, I will have to get some and experiment. Thanks for sharing! I have to find a box of thin mints before I can give it a whirl 😉

  8. says

    This looks amazing! I can’t believe it is skinny. I don’t like bananas, but I am going to take your word for it and try this because it looks too delicious to not try! Xanthan gum also kind of scares me, but to get such an amazing creamy texture – I’m going out of my comfort zone and getting some! Pinned!

  9. says

    Oooh, delicious! The fact that this shake is skinny is blowing my mind! And purchasing xanthan gum was a total game-changer for me when it comes to making smoothies. Sometimes finding the right amount to use is finicky (…added too much once – YUCK), but it does so much for consistency!

  10. says

    This looks so pretty!!! :)

    I’m a big protein shake drinker (like every morning) and I don’t know which one of these I want to try first. I love the thin mint cookies but the pumpkin pie looks yummy too! Thanks for adding some great recipes to my list. Pinning!
