A sweet, tart, and creamy 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 shake (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!
- 1 scoop vanilla protein powder (I used Quest Vanilla Milkshake Protein Powder, which has 100 calories per scoop)
- ¾ cup Almond Breeze unsweetened almond milk (Original or Vanilla flavored)
- ¾ cup freshly-squeezed lime juice
- Zest from 1 lime (about 2 teaspoons)
- Pinch of salt
- 1-2 cups ice
- For topping: ½ of a wholegrain graham cracker, crushed {See note below for a homemade version!}
- Add first 6 ingredients to blender and combine! Top with graham cracker crumbs and serve immediately.

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!
