Get a taste of the tropics in under five minutes with this refreshing key lime smoothie. It’s a go-to for mornings or when you want something light after dinner. It’s zippy, creamy, and you probably have everything to make it right in your kitchen. Banana, a splash of lime, and just a bit of honey blend together for a sippable twist on the classic. Trust me, once you try it, you’ll want it every time you need a little boost. I first whipped this up on one seriously hot summer afternoon and I keep coming back to it whenever the sun is blaring.
The first time I tasted this, I was hunting for a fun treat that wouldn’t weigh me down. Now, I stash frozen bananas on standby just in case. It’s become my standby cool-down snack for hot afternoons that calls for something filling but super fresh.
Bright Ingredients
- Optional toppings: Throw on crushed graham crackers or even gluten-free cookies and a wedge of lime for the full vibe
- Optional spinach: A handful adds a green splash but don’t worry—you won’t taste it, just rinse it first
- Optional ice: Chuck in a few cubes if you want it extra thick and icy
- Pure vanilla extract: Balances out the lime with a little roundness—if you can, grab the real stuff
- Finely grated lime zest: Packs in big citrus energy—try for unwaxed limes to zest
- Honey or whatever sweetener you love: You’re in charge of how sweet you want it, and local honey adds a nice touch
- Fresh key lime or regular lime juice: You get all the classic zing, so make sure it’s squeezed fresh for that bright pop
- Plain Greek or a thick dairy-free yogurt: Adds protein and a pie-like texture—lower sugar ones are best
- Frozen banana: For creaminess and that natural sweetness—freeze them really ripe and you’re set
Easy How-To
- Garnish and Enjoy:
- Want it fancy? Rub lime juice around your glass and dip the rim in crushed graham crackers. Pour in your smoothie, give it a sprinkle of zest, or pop a lime wedge on top. Enjoy right away!
- Taste Test:
- Take a sip. Want it tangier? Squeeze a little more lime in. Needs to be sweeter? Add another squirt of honey or even maple syrup. If it’s too thick, pour in a splash of water or almond milk and give it another spin.
- Blend It All:
- Pop the frozen banana, yogurt, lime juice, honey, zest, and vanilla into your blender. Add ice if you want it really frosty. Now’s the moment for the spinach. Blend ’til it’s creamy and smooth, scraping the sides if you have to.
- Get Prepped:
- Slice up your banana and let it freeze for a few hours so it’s really cold. Juice and zest the limes right before you start mixing so you catch those citrusy oils.

Good to Remember
- Freeze leftover smoothie in molds to make easy popsicles later
- Packed with fiber, vitamin C, and potassium
- Works for anyone eating gluten-free or dairy-free (just swap in your favorite yogurt)
The lime zest is my favorite part because it brings back memories of family picnics and scrambles for the last purple of key lime pie. It’s all about that bold, citrusy punch that just screams summer fun and good company.

How to Store
This drink is best right after you make it, but extras are easy to freeze. Just pour into ice cube trays, freeze, then toss a few cubes back in the blender with a splash of milk for a speedy refresher. They’ll stay good for up to three months sealed tight—perfect for days you’ve got a surplus of bananas or lime.
Swaps and Options
No key limes? Regular limes or even lemons totally work. Swap Greek yogurt for coconut or cashew yogurt to make it dairy-free. Agave and maple syrup swap in great for honey. If you want a nutty flavor, add a spoonful of cashew butter to switch up the vibe.
Fun Ways to Serve
Pour it into cold glasses and pile on coconut whipped cream and crumbs for a dessert-style treat. Kids love building their own smoothie bowls with granola and fresh fruit. Or freeze into pops for a sunny day snack that’s hands-free.
Sunshine in a Glass
This one’s inspired by our Florida trips and the zippy pies we’d always munch on by the beach. That tart, zingy flavor just reminds me of sandy feet and easy-going meals outside. Now you can put a bit of sunshine right in your breakfast glass.
