This 3 ingredient smoothie is easy, healthy, and delicious. It’s loved by kids and adults alike, and you can whip it up in minutes!

Busy mornings? Picky eaters? Craving something sweet but still nutritious? This three-ingredient fruit smoothie has your back.
It’s the easiest smoothie you’ll ever make. It uses just frozen mixed berries, creamy oatmilk, and a bit of maple syrup. That’s it. And yes – it’s really that delicious.
Kids love the fruity flavor, and you’ll love the fact that it’s packed with vitamins and fiber. No prep. No fuss. Just blend and enjoy.
Ingredients
Here’s what you’ll need:
- 6 oz. frozen mixed berries (strawberries, blueberries, blackberries, raspberries)
- 1 cup oatmilk (unsweetened or vanilla works best)
- 1 tablespoon maple syrup (for a hint of natural sweetness)
It’s that easy… just three ingredients. Keep them on hand and you’ll always be smoothie-ready.
Tools You’ll Need
- Measuring cup
- Measuring spoon
- Blender (this personal blender might just be my favorite kitchen appliance!)
- Mason jar or cup for serving (this recipe fits a pint-size mason jar perfectly!)
We highly recommend using a high-powered personal blender. A good blender makes all the difference. It ensures a smooth texture and blends frozen fruit in seconds.
Cheap or weak blenders can leave you with icy chunks and inconsistent results. Invest in a solid personal blender – you’ll use it constantly.
Directions
- Measure 6 oz. of frozen berries and pour into the blender.
- Add 1 cup of oatmilk on top of the berries.

- Drizzle 1 tablespoon maple syrup over the mixture.

- Secure the lid and blend for 20-30 seconds or until smooth and no fruit chunks remain.

- Pour into a mason jar or your favorite cup.
- Serve immediately and enjoy!
You can double the recipe for a larger serving or to share with your kids.
Why This Smoothie Is So Great for Kids
This smoothie is a win-win for parents and little ones alike. Here’s why:
- Berries are packed with antioxidants and vitamin C.
- Oatmilk is often fortified with calcium and vitamin D.
- Maple syrup offers a natural alternative to refined sugar.
Kids think it’s a treat. You know it’s actually good for them. It’s also a great way to introduce fruits to picky eaters. Plus, the cold and creamy texture makes it feel like a milkshake. But there’s no ice cream, no dairy, and no added junk.
Variations to Try
Want to mix it up? Here are a few fun and easy ideas:
- Add Greens: Throw in a small handful of spinach for an invisible nutrition boost. It’ll change the color a little but won’t change the flavor much at all.
- Add Banana: Toss in half a frozen banana for extra creaminess and natural sweetness.
- Try Other Frozen Fruits: Like Peaches? Mango? Pineapple? Try any frozen fruit in place of frozen berries.
- Nut Butter Boost: Add a spoonful of almond or peanut butter for protein and healthy fats.
- Make It a Bowl: Pour the smoothie into a bowl and top with homemade granola, chia seeds, or fresh fruit.
- Add Flavor: Try a dash of vanilla extract, cinnamon, or lemon zest for a twist.
- Go Dessert-Style: Add a teaspoon of cocoa powder and top with dark chocolate shavings.
Smoothies are flexible. Feel free to get creative with whatever you have on hand.

Clean-Up Tips
Cleaning your blender right away makes life easier. After pouring your smoothie:
- Rinse the cup and blade immediately.
- Fill it halfway with warm water and a drop of soap.
- Blend for a few seconds and rinse again.
This trick saves you from scrubbing later.
FAQs
- Can I use fresh berries instead of frozen? Yes, but the smoothie will be thinner. Add a few ice cubes to chill and thicken.
- Is oatmilk the best option? We love oatmilk for its creaminess, but any milk works – almond, dairy, soy, or coconut.
- Can I make it ahead of time? I don’t recommend making it ahead. Separation occurs if you refrigerate it, which changes the texture. And it can lose its beautiful color.
- Is maple syrup necessary? Nope! If your fruit is sweet enough, skip it. Or use honey or agave as alternatives.
- How do I make it thicker? Use less milk or add extra frozen berries or banana to thicken the texture. Adding oatmeal is a good option AND it adds extra nutritional benefits.
- Is this smoothie vegan? Yes! It’s 100% vegan as written. Just keep your add-ins plant-based, too.
- Can I add protein powder? Absolutely. A scoop of vanilla or berry protein powder works well here.
- What if I don’t have a personal blender? A full-size blender works too. If using a full-size blender, consider doubling the recipe so there’s enough to blend smoothly.
This three-ingredient fruit smoothie is the definition of easy. You don’t need fancy ingredients and you don’t need a lot of time. It’s healthy, colorful, and full of flavor. Perfect for breakfast, snacks, or a quick energy boost before school or work.
Once you make it, you’ll want to keep the ingredients stocked at all times. Trust me – your blender will be working overtime.
And remember: the better your personal blender, the smoother your smoothies. Invest in one with strong blades and easy cleanup. It’ll become your new favorite kitchen tool for smoothies, dressings, dips, blended coffees, and so much more.
