A sweet, tart, and creamy Easy Key Lime Pie Protein Smoothie is the perfect healthy breakfast or clean eating snack to satisfy your sweet tooth!

So this idea originally came about when I was dreaming of GREEN foods for St. Patty’s Day. But guess what? It’s not soooooo green (unless you count the little green flecks of lime zest sprinkled throughout!).

I briefly considered adding a few drops of food coloring to make it really festive, but then I decided EWWWW…no, thanks. Instead I settled for a less vibrant and easy key lime pie smoothie (that’s still bursting with flavor!). Ya with me?!

Whether it’s green, white, or somewhere in between…this protein smoothie is such a delicious way to celebrate the EVERY day (not just a holiday). It’s full of protein and vitamin C to help keep you healthy, strong, and fueled. BUT, with a sweet graham cracker crumb topping and a smooth, creamy base, it’s tasty enough to curb those real pie cravings! Snack time? Dessert? Check. Check.

I often rely on the convenience of packaged, organic, wholegrain graham crackers for the boys and myself, but if you have a few spare minutes (and really, that’s all you need!), you can even make your own Homemade Whole Wheat Graham Crackers with one bowl and a couple of pantry staples (no mixer required!).

Grab my recipe HERE — they can be crumbled on top of the smoothie, but they’re also just a really great make-ahead snack or addition to breakfast on-the-go. Totally freezer-friendly, too!

And be sure to go with some fresh lime here (not the stuff in a bottle) for maximum taste and quality! Bonus points if your grocery store actually sells KEY limes!! Can’t beat what Mother Nature gave us!

    You make the best smoothies, Blair! I’ve never even thought to make a lime smoothie before, so I’m loving this delicious combo. And even better that there’s protein in it, too. Just what I need to get going on this Monday morning!

    Wow, I can’t remember the last time that I had a slice of key lime pie and it’s one of my favorites! That being said, I have all of the ingredients for this delicious smoothie on hand, and this is about to go down! I absolutely LOVE finding healthier alternatives to sinful sweets 😉

    Oh I am SO glad you didn’t add the food coloring. This smoothie is so beautiful as is, and it totally screams key lime pie. That is my hubby’s fav dessert so I know he’ll love this! Weekend treat!!

    1. Blair says:

      Yep, perfect weekend treat for the key lime pie LOVER! 🙂 Thanks, Chrissa!

  10. Beth says:

    My boyfriend loves key lime pie . We made this recipe after a hard workout and with our last scoop of protein in our house. The drink came our way to sour and neither of us could drink it. We tried to mix in more almond milk to drowned out the sourness. Nothing worked!

    1. Erica Scruggs says:

      Same here. Waaaay too sour. Is 3/4c lime juice a typo??

      1. Blair says:

        Hi, Erica! Did you use the Quest brand vanilla protein powder that I recommend? That’s the only powder that I’ve used to test the recipe, and I find that the creamy, sweet vanilla powder cuts the lime juice so that it’s not too sour at all. I don’t know how it would work or taste with other brands or other amounts of powder.

    2. Janelle says:

      Ya I used vanilla protein powder too and it is so sour. I added more and it helped a bit but i wasn’t trying to double my calories. Also took me about 10 dang limes to get that much juice.

  11. Sarah says:

    Please don’t give your toddlers protein powder with sucralose in it.

  12. Julie says:

    I used Hemp powder because I didn’t want any powders with artificial sweeteners. Added yogurt. It’s alright. Very tart. I’d use less lime next time.

    1. Blair says:

      Hey, Julie! Yes, the unsweetened hemp powder and the yogurt would make it incredibly tart. That’s why I like the vanilla flavored protein powder, because it adds sweetness and creaminess to balance the lime. 🙂

  13. Leanne Long says:

    2 grams of protein does NOT make a protein smoothie. Sounds wonderful but the protein is practically non-existant.

    1. Blair says:

      You’re right — that wouldn’t be much protein! 🙂 That was a typo — it should say 23.5 grams of protein. I updated the nutrition panel to correct it. Thanks for letting me know!

  14. Kathy says:

    Why not add some spinach or other healthy greens in it to make it a pretty shade of green and add fiber and antioxidants too! I love to “hide” greens in smoothies. Drinking them is so much easier than eating them, LOL!

    1. Blair says:

      Great idea, Kathy!

  15. Randi says:

    5 stars
    Love it! I’m excited to recommend your smoothies to the happy.ly community!

  16. JB says:

    tastes too much like lemonade and not like key lime pie. and i added 1/4 cup up lime juice.

  17. Paula says:

    5 stars
    Omg! Delicious! I used Gauge girl vanilla protein powder. This is the best recipe, ever! Thank you!

    1. Blair says:

      Thanks, Paula! 🙂

  18. Heather says:

    this seems like a lot of lime juice. should i really add a full 3/4 cup lime juice? and shouldn’t i use key lime juice?

    1. Blair says:

      That’s how I like it, but you can always start with less lime juice and see how it tastes. You might prefer less, but you can always add more if necessary. Key lime juice is great if you have access to it!

  19. Lisa says:

    5 stars
    I Love this smoothie. I only put 1/2 cup of fresh squeezed key lime juice and it was perfect. Still tart but that’s what I loved about it. I’ll definitely be making this again.

    1. Blair Lonergan says:

      Thanks, Lisa!

  20. Amy says:

    This sounds delicious but I am allergic to nuts. Can I substitute milk for the almond milk? Any other suggestions? Would love to try it.

    1. Blair Lonergan says:

      Yes, absolutely! Any variety of milk will work well. Hope you enjoy it, Amy. 🙂
