This coconut key lime pie smoothie transforms everyone's favorite tangy dessert into a nutrient-packed beverage you can enjoy any time of day. The creamy texture and perfect balance of sweet coconut and tart lime create a tropical escape in every sip, while secretly delivering protein and veggies.
The first time I made this smoothie was during a summer heatwave when I was craving key lime pie but didn't want to turn on the oven. My family was shocked when I told them there was spinach hidden inside their creamy green "dessert"!
Ingredients
- Frozen banana: creates the creamy ice cream like texture without actual cream

Step-by-Step Instructions
- Prep Your Glass:
- Take a moment to create that signature graham cracker rim. Moisten the edge of your glass with a lime wedge then gently roll it in graham cracker crumbs. This step transforms a simple smoothie into an impressive treat that truly mimics key lime pie.
- Blend The Base:
- Add your frozen banana lime zest lime juice yogurt and coconut milk to the blender. This combination creates the creamy base that will remind you of key lime pie filling. Make sure your banana is properly frozen for best texture.
- Incorporate Spinach:
- Add spinach and vanilla extract to the mixture. The spinach provides gorgeous color and nutrients without affecting the flavor profile. Blend on high speed until completely smooth with no visible green flecks.
- Taste And Adjust:
- Before serving taste your smoothie and add sweetener if needed. If using vanilla yogurt you may not need additional sweetness. Adjust thickness by adding more liquid if too thick or more frozen banana if too thin.
- Garnish And Serve:
- Pour your smoothie into the prepared glass and top with whipped cream and toasted coconut. These final touches elevate the presentation and complete the dessert like experience.

My absolute favorite ingredient in this smoothie is the lime zest. I used to skip this step thinking juice was enough, but the aromatic oils in the zest give that authentic key lime pie flavor that makes this smoothie truly special. When my daughter first tried it, she asked if we could have "pie smoothies" every morning!
Storage Tips
While this smoothie is best enjoyed immediately, you can prep ingredients ahead of time to streamline your morning routine. Place all non liquid ingredients in a freezer bag the night before so all you need to do is dump and blend in the morning.
If you absolutely must store a prepared smoothie, transfer it to an airtight container and refrigerate for up to 24 hours. The texture will change slightly as it sits, so give it a good shake or quick re blend before enjoying.
Nutritional Benefits
The beauty of this smoothie lies in its nutritional profile that disguises itself as dessert. One serving provides valuable potassium from bananas, vitamin C from fresh lime, protein from Greek yogurt, and iron from spinach.
The healthy fats in coconut milk help your body absorb fat soluble vitamins while giving the smoothie its luxurious mouthfeel. When made with low fat yogurt, this smoothie delivers impressive nutrition for relatively few calories, making it a balanced choice for breakfast or snack.
Seasonal Variations
During summer months when fresh key limes are available, substitute regular limes for these smaller, more aromatic fruits. Their distinct flavor profile takes this smoothie to another level of authenticity.
In winter when you need a tropical escape, add a handful of frozen mango or pineapple to enhance the vacation vibes. The additional tropical fruits complement the coconut lime flavors perfectly while adding even more nutritional benefits.
