Simple How-To Steps
- Serve Up and Finish:
- Pour that smoothie into your decked out glass and pop on a lime wedge if you want. Best enjoyed right away for ultra creaminess.
- Get Your Glass Ready:
- Rub some lime juice on the glass edge and then press it right into those graham crumbs so you get a nice, crunchy rim.
- Set the Texture:
- Drop in some ice, a bit at a time, and blend again until it’s as thick or thin as you like. More ice for a thick shake vibe, less if you want it easier to sip.
- Start Blending:
- Chuck the frozen banana pieces, yogurt, key lime juice, honey, zest, and vanilla into your blender. If you want a punch of green, throw in spinach. Blend on high till it’s smooth. Scrape sides to make sure nothing’s left chunky.

Don’t even think about skipping the lime zest. I did once and it just didn’t pop – no sparkle. That zest boost is what takes it all the way and my family was hooked after the first round.
Keeping It Fresh
Any extras? Pour the leftover smoothie into ice cube trays and freeze them. When you want another, just blend with some milk for a cold, creamy treat within three months. This keeps it super thick, never runny.
Handy Swaps
No Greek yogurt? Any thick yogurt will do or even some silken tofu for plant based peeps. Can’t get limes? Lemon juice and zest are great, too. Want it luxurious? Toss in a little cream cheese instead of some of the yogurt to get that classic pie feel.

Fun Ways to Serve
Make it fancy by serving in glasses with the graham rim and a curl of lime. Kids love it as frozen pops – simply add a little more honey, pour into molds, and freeze for an easy snack.
Frequently Asked Questions
- → How do I make it creamier?
Try swapping out 2 spoonfuls of Greek yogurt for cream cheese before blending. It gets extra thick and smooth, closer to a pie filling.
- → No key limes—what can I use?
Sure thing! Regular lime juice and zest give the same zing here. Go ahead and use what you've got.
- → Don't want to use honey?
No problem—use agave, maple syrup, or whatever sweetener you like best. Pick what works for you.
- → How can I boost the green color?
Toss in a small handful of raw spinach before you blend. The color gets brighter without affecting how it tastes.
- → Got a fun way to serve this?
Pour chilled smoothie into a glass with crushed graham cracker around the rim, and plop on a lime wedge for fun.
- → Leftover smoothie tips?
Pop extras into an ice cube tray. Blend the cubes later with a little milk or yogurt and you’ve got a ready-made fast snack—stays good for about three months.
