If you want a quick, chilly drink that’s packed with fruity goodness and a bit of protein, this Banana Watermelon Pineapple Smoothie is for you. There’s no milk or extra sweetener in sight—just big tropical flavor. I reach for this on hot days or any time I want something tasty and a little healthy.
When July gets sweaty, this is hands down my favorite. My kids are pineapple super fans; they say it’s like a sip-able frozen treat.
All You Need
- Collagen powder: One scoop is plenty, totally optional. Try vanilla if you want, just make sure it blends right in.
- Frozen pineapple: One cup, and make sure it smells sweet and looks bright and golden yellow—that’s when it’s perfect.
- Frozen banana: One cup—just one small banana, really ripe. Peel, slice, freeze in a bag so it’s ready.
- Watermelon: Two cups, chunked up. Seedless is easiest and sweetest, and it blends up quick.
- Pro tip: At least one fruit has to be frozen to make it nice and thick. Double up on frozen stuff if you want that frosty, slushy texture.
Easy How-To
- Serve It Up:
- As soon as it’s blended, pour into your favorite glasses. Pop on a pineapple wedge or scoop a few watermelon balls on top if you want to have fun with it.
- Tweak the Taste:
- Try a spoonful. If it’s looking too thick, splash in some water, coconut water, or plant milk to thin it out. Need more sweetness? Drop in another half a banana.
- Smooth Blend:
- Blend on high until totally smooth—no chunky bits left. Grab a spatula and scrape the sides if fruit sticks.
- Blender Load:
- Dump everything into your blender. Watermelon should go closest to the blades. If you’ve got unfrozen banana, drop it down first too so it blends better.

Every time I make this, I think of sunny park picnics where we'd haul watermelon and eat slices straight from the cooler. Watermelon and pineapple together always feels like a celebration to me.
Keep It Fresh
This one’s best sipped right away, but fridge leftovers last a day. Give the jar a good shake or stir—it can separate a bit. If you’ve got an insulated bottle, fill it all the way and you’re set for a cool grab-and-go drink later on.
Swap It Out
If you’re short on pineapple, mango works in a pinch. Toss in mixed berries for a different kind of fresh spin. Want more protein? Use your favorite plant protein powder or just leave it out for a fruit-only drink.
Try Serving Like This
This smoothie is awesome solo, but pairs nicely with crunchy granola or toasted coconut. If you’re doing brunch, set it next to egg muffins or a pile of yogurt and toppings for a sweet and filling start.

Frequently Asked Questions
- → Can I use fresh fruit instead of frozen?
Definitely. But frozen banana and pineapple make things colder and thicker. If your fruit's fresh, just add a few ice cubes to cool it down.
- → How can I make this smoothie vegan?
All you have to do is leave out the collagen powder. Everything else is already plant stuff and skips the dairy.
- → What can I use if the smoothie is too thick?
If it's too dense, pour in a bit of water, coconut water, or milk until you like the texture.
- → Is extra sweetener needed?
Nope, the fruit already makes it sweet enough. Want it extra sweet? Toss in another banana or swirl in some honey.
- → Will the smoothie still blend well without added liquid?
Yep, since watermelon has a bunch of water in it. Start with it close to the blades so it blends up easily.
- → Can I prep the ingredients ahead of time?
Sure you can. Slice and freeze the fruit before and you'll save time plus get a colder, thicker drink each go.
