Craving a chilly, fruity treat loaded with some plant protein? Make this Banana Watermelon Pineapple Smoothie. It's got simple, real ingredients and comes together in a snap. I whip it up whenever it's hot or I'm just after something that's delicious and feels a little good-for-you too.
When midsummer heat hits, this one wins every time. My kids can't get enough pineapple—they think it tastes just like eating a frozen popsicle, but in a glass.
Chilled Essentials
- Frozen banana: About a cup—just slice and freeze a ripe one ahead in a bag. The riper, the better.
- Frozen pineapple: Aim for a cup, look for pieces that smell sweet and are that perfect deep yellow.
- Collagen powder: Toss in a scoop if you want. Try vanilla for something extra, but make sure it disappears right into the mix.
- Watermelon: Two cups of chunks. Go seedless to keep things simple and sweet, plus it blends in no time.
- Smart move: You need something frozen, or it won't get that thick texture. Stack the blender with extra frozen fruit for an icier, slushy feel.
Super-Easy Directions
- Start Blending:
- Everything goes in the blender—watermelon by the blades. If your banana isn't frozen, put that in first too for the smoothest blend.
- Blend It Smooth:
- Let it run on high so it’s totally creamy—no bites left behind. Scrape down the sides if stuff is sticking up high.
- Test & Adjust:
- Give it a taste. Too thick? Add some water, coconut water, or your fave plant milk. Not sweet enough? Throw in more banana.
- Pour & Garnish:
- As soon as it’s blended, fill up your glasses. Add a pineapple slice or a couple watermelon balls on top for fun.

Blending this up always reminds me of sunny afternoons at the park, slicing up watermelon fresh from our cooler. Mixing pineapple and watermelon flips an ordinary drink into a mini celebration every time.
Stay Cool
Honestly, this is best when you drink it soon after making. If you end up with extras, stash it in the fridge for a day. Shake or stir well—stuff can settle out. An insulated bottle keeps it icy cold for later sipping.
Change Things Up
No pineapple? Mango can totally step in. Try mixed berries for something new. Want to bump up the protein? Swap in your favorite plant powder, or just stick to fruit if that’s your jam.
Serving Fun
It’s tasty all by itself, but I love it with crunchy granola or a sprinkle of toasted coconut. Makes a great side if you’re doing brunch—nice next to egg muffins or a big bowl of yogurt with your favorite toppings.

Common Questions
- → Is it okay to swap in fresh fruit for the frozen kind?
Absolutely! Though frozen banana and pineapple get your drink nice and chilly. If you're using fresh, just pop in a handful of ice to cool things down.
- → What's the vegan option here?
Just skip the collagen and you're set! Everything else in here comes from plants and skips animal stuff.
- → What should I do if my smoothie turns out thick?
Just pour in some coconut water, milk, or plain water till it loosens up enough for you to sip easily.
- → Do I really need to add any sweetener?
Not really—the fruit's got you covered. But if you're after a bigger sugar hit, mix in an extra banana or a squirt of honey.
- → Will blending work even if I skip extra liquid?
You bet! Watermelon is super juicy, just drop it near the blades and it'll get things swirling smoothly.
- → Can I get stuff ready the night before?
For sure. Pre-slice and freeze your fruit ahead of time. It makes the drink colder and shaves a few minutes off your prep in the morning.
