Coconut key lime pie smoothie brings together zippy lime and creamy coconut for a taste of the tropics in every sip. It's loaded with protein and leafy greens, so you're getting a healthy kick along with those sunny dessert vibes. Whip one up for breakfast, after your workout, or treat yourself to a sweet smoothie twist on classic pie.
Made this up on a warm day because my little ones were craving something fun. I was after something that wouldn’t send me crashing later. They loved it straight away, so now it’s a go-to at my house.
Tasty Ingredients
- Frozen ripe banana: Toss in slices of frozen banana for instant creaminess and sweet flavor. It turns your smoothie thick and cold with zero ice needed.
- Lime zest: Use fresh lime zest for that citrus blast. Go with key or regular limes—just zest them right before blending.
- Fresh lime juice: Brings a tangy punch. Fresh squeezed is best and key limes have extra zing.
- Vanilla or coconut Greek yogurt: Yogurt keeps things thick and boosts the protein. Greek is my favorite, but you can swap coconut yogurt for a dairy-free spin. If you luck out and find a key lime version, your smoothie will taste even more pie-like.
- Light coconut milk: Rich coconut milk means creamy, lush smoothies. Any type works—go for canned if you want dessert-level richness or swap in any milk you like.
- Fresh spinach: You won't taste it, but you'll see the color and sneak in good-for-you greens. Toss in half a cup or more if you’re feeling bold.
- Vanilla extract: Helps the smoothie taste sweeter and more like dessert. Use a splash of the good stuff for best results.
- Maple syrup or honey: Optional but handy if your smoothie isn't sweet enough. Taste first—yogurt might bring all the sweetness you want.
- Graham cracker crumbs: Roll your glass rim in these for a pie-style crunch—any brand you love works here.
- Whipped cream: Add a big dollop on top for a treat. You can go regular or coconut-based for a dairy-free topping.
- Shredded toasted coconut: Sprinkle toasted coconut over your drink to finish—this adds a golden toasty kick and makes the smoothie look great.
Simple Steps
- Serve and Top:
- Pour that thick smoothie into your rimmed glass. Spoon on a swirl of whipped cream and toss on some toasted coconut to finish. Stick in a straw and dive in!
- Taste and Sweeten:
- Give your smoothie a taste. If it needs more sweetness, add maple syrup or honey and buzz it again if you want.
- Blend the Smoothie:
- Dump in banana, lime zest, lime juice, yogurt, coconut milk, spinach, and vanilla extract into your blender. Blend everything up until it’s silky smooth. If it's too thick, just splash in more milk until it's pourable.
- Prep the Glass:
- Take a lime wedge and run it around your glass rim. Press that rim into crushed graham crackers piled on a plate so the crumbs cling all around for that crusty edge.

Good Things to Know
- You’ll sneak in leafy greens without anyone knowing
- Yogurt and coconut add richness that actually keeps you full
- Whenever you need a breakfast, snack, or treat, it blends up in minutes
The star for me is the lime zest. When I grate it, the bright smell tells my kids that something awesome is coming. I love seeing them get whipped cream all over their faces on the first gulp.
Storing Your Smoothie
Mix it up the night before, then cover and chill in the fridge. When you're ready, give it a good shake or another quick blend, since it might thicken as it sits. Or freeze it into pops for a different kind of cold snack.

Swap Options
If you need it dairy-free, use coconut or almond yogurt. No spinach? Sub in baby kale instead. Want extra protein? Toss in some protein powder. You can use different kinds of milk, but coconut milk really brings out that decadent feel.
How to Serve
Coat the rim with graham crumbs for that pie feeling. For bonus points, chill the glass before pouring. Top with toasted coconut or a lime wedge for a tropical pop. It even works as a cute mini treat in small glasses with little spoons.
