Craving a cold, fruity drink with a pop of protein? This Banana Watermelon Pineapple Smoothie totally hits the spot. No milk or added sugar here—just bold flavors that feel like summer. I love grabbing this on warm days or anytime I’m in the mood for something tasty and sorta nourishing.
When July gets sticky and I’m sweating, I go straight for this one. My kids are wild about pineapple—they swear it’s like sipping on a frozen dessert.
Vibrant Ingredients
- Watermelon: Two cups, chopped. Use seedless—super sweet and blends up nice and quick.
- Frozen banana: About a cup from one little, really ripe banana. Just slice, toss in a bag, and freeze till you need it.
- Frozen pineapple: One cup—go for pieces that smell great and look golden-yellow so you know they’re perfect.
- Collagen powder: Totally up to you—one scoop if you want it. Vanilla’s fun, too. Just make sure it disappears into the mix.
- Here’s a trick: Freeze at least one fruit for the creamiest, thickest texture. If you want a super frosty treat, double up on frozen fruit.
Simple Steps
- Start Blending:
- Toss it all in the blender, putting watermelon first by the blades. If your banana isn’t frozen, send it to the bottom too—makes blending easier.
- Smooth It Out:
- Blast it on high till it’s all silky—no lumps. Pause if you need to scrape down the sides.
- Change Things Up:
- Give it a taste. Too thick? Splash in a bit of water, coconut water, or your go-to plant milk. Want sweeter? Add half a banana.
- Pour and Garnish:
- Pour into glasses and have fun with it—drop in a pineapple wedge or a few watermelon balls if you like a little extra flair.

Every time I whip this up, I think of lazy park days, munching watermelon straight from the cooler. Blending pineapple and watermelon always feels super festive.
Stay Cool
This drink tastes best fresh, but you can stash leftovers in the fridge for a day. If it separates, shake or stir it up. Got an insulated bottle? Fill it good and tight for a chilled treat later.
Switch Things Up
No pineapple? Grab some mango—it gets the job done. Want a new twist? Chuck in a few mixed berries. Need more protein? Go for your favorite plant protein or just keep it all fruit if that’s what you’re feeling.
Fun Ways to Serve
Honestly, it’s delicious on its own, but it’s even better with some crispy granola or toasted coconut on top. If you’re calling it brunch, set it beside egg muffins or yogurt bowls loaded with toppings for an awesome morning spread.

Common Questions
- → Is it okay to use fresh fruit instead of frozen?
Go for it. Using frozen pineapple and banana makes it colder and thicker. Got fresh fruit? Just add some ice cubes—easy fix.
- → What's the vegan swap for this smoothie?
Just skip the collagen powder. All the other stuff is made from plants and already doesn’t use dairy.
- → What if it ends up too thick to drink?
If it's too much like pudding, add milk, coconut water, or regular water until it’s sippable again.
- → Is there any need for extra sweetener?
The fruit brings plenty of sweetness. If you need more, add an extra banana or drizzle in a little honey.
- → Will it blend if I don’t put in extra liquid?
Sure will. Watermelon’s juicy enough. Put it by the blender blades for a head start.
- → Can the fruit be prepped upfront?
Yep! Slice up everything and freeze it ahead, then just toss it in when you want. Saves time and makes each batch colder.
