This healthy strawberry, blackberry and banana smoothie is ultra creamy and packed with amazing fruity flavors. Makes for a refreshing but also satisfying breakfast, mid-day snack or post workout drink. Also, filled with good-for-you ingredients!

You know how much I love a good smoothie to start the day! We absolutely love this dessert-like strawberry and chocolate smoothie, especially our kids, or this banana chai smoothie that's amazing in the fall.
And this strawberry, blackberry and banana creamy smoothie now often finds its way in our breakfast routine. We might swap the blackberries for blueberries depending of what's available, but there is just something unique, fresh and super juicy from using blackberries.
And what's great about fruit smoothies is that no matter what fruits you are using, you can always enjoy them any time of the year by choosing frozen fruits. Plus, they adds so much more creaminess compared to fresh fruits, especially frozen bananas!

Fruit smoothie health benefits
Smoothie are such a healthy way to start the day! They are quick and easy, but also, you can get a few portions of fruits right from the beginning of the day.
This recipe is packed with amazingly healthy berries. They provide a fair amount of antioxidants, but also are rich in fiber and vitamins. And although fairly low in sugar, they can help sweeten your smoothie naturally, so you don't have to add any extra sweetener.
Using overripe bananas will also make the drink much sweeter naturally, but did you know that bananas are very rich in potassium, antioxidants and vitamins too? And they are not expensive and easy to find any time of the year, other reasons to eat them more!
One more thing, rolled oats are also included in this recipe. In this case, adding whole grain creates a smoothie that's thicker and feels more substantial, but also, oats are incredibly healthy! They include important nutrients, such as fiber, vitamins, minerals and even some protein.
Ingredients needed
- Frozen bananas: I would highly recommend using frozen bananas. They make smoothies so heavenly creamy and rich. Simply buy more when grocery shopping, let them ripen on the counter and then peel them. Place them on a parchment paper covered baking sheet and freeze for a few hours before transferring in a large bag or container for longer storage.
- Fresh or frozen blackberries: use fresh when in season, or freeze them the day before for an extra chilled smoothie.
- Fresh or frozen strawberries: I usually buy already frozen strawberries for convenience.
- Rolled oats: choose old-fashioned rolled oats. They add lots of nutrition and make the smoothie thicker and more filling.
- Plant-based milk: any kinds will work well. Choose unflavored and unsweetened so you can control the flavor yourself.
- Chia or hemp seeds: add healthy fats, extra fiber and protein too.
- Cinnamon: for flavoring, can also use vanilla extract, a dash of cacao powder or simply omit.

How to make it
Combine
Simply combine all ingredients in a blender. Start by pouring the milk first, then add the fruits and seeds. This will avoid the fruit to get stuck at the bottom of the blender.
Blend
Blend on high speed for at least a minute. I like to pause once to scrape the walls and be sure all fruits are incorporated. Also, blackberries have tiny seeds, so blend long enough to create a smoother consistency.
Serve
Pour in either 2 small glasses or one large. Enjoy right away.

Tips
- I highly recommend using frozen fruits if possible. If you only have fresh berries, then you might want to start with less milk and add more as needed, since the smoothie will already be juicier. In any cases, you will need a frozen banana to reach a super creamy smoothie.
- As already mentioned, pouring the milk first is a simple trick to avoid all the fruits to get stuck at the bottom of the blender, especially when using frozen fruits.
- Avoid adding ice cubes whenever possible as this will dilute the flavors.
- This smoothie is naturally quite sweet, so I bet you won't need any added sweetener. If your fruits are on a sour side, especially the blackberries, then add a splash of maple syrup or a softened medjool date.

Serving suggestion
Serve right away while still cold and frozen with a straw and top with fresh fruits and chia/hemp seeds.
If serving as a healthy dessert or mid-day snack, then garnish with coconut whipped cream.
You could also serve it as a smoothie bowl. In that case, start with less milk to make it thicker. Pour in a bowl and top with granola, a drizzle of nut/seed butter, chia or hemp seeds and fresh fruits. Dig in with a spoon!
FAQ's
Smoothie are best when enjoyed right away. If you do have more than you can drink, then keep covered in the fridge for up to 24 hours. To serve, blend again quickly with a few ice cubes just to refresh it.
You can measure the frozen fruits, rolled oats and seeds ahead of time and store individual portions in your freezer in small container. That way, you only have to throw the ingredients in the blender and add the milk.
You can boost its protein content so it makes for a full meal and keep your hunger away longer. Add a scoop of plant-based protein powder, a tablespoon of peanut or almond butter or simply more seeds.
In my case, this makes for one larger portion, as it is often the only thing I eat in the morning. But, also makes for 2 smaller portions, especially if serving for kids or with toasts.
