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! If you do find fresh key limes, stock up and make a key lime icebox cake, too!

I make mine with 2 sprinkles of protein packed cookie butter granola (Kodak brand I believe) as a substitute for the graham cracker crust-it gives it a yummier flavor, plus added protein! Also, I add 2/3tbsp chobani lime Greek yogurt, 2-3tbsp unsweetened plain Greek yogurt, and Organic unsweetened coconut milk in place of the almond milk. I also add a little a little splash of coconut water (I prefer Mojo brand, but you can use whatever brand you fancy)., 1tbsp organic heavy cream & a splash of Fairlife 2% milk (as Fairlife milk contains 50% less sugar and 50% more protein than regular milk). Talk about to DIE for!
Yum! Thank you for sharing, Mattie.
