“I just used frozen blueberries and bananas, wonderful taste!” —Nancy

Add your review

Here’s what you’ll need

This smoothie recipe only requires four main ingredients (most of which you probably already have in your kitchen). This is just an overview – jump to the recipe card for measurements and printable instructions!

Blueberries: Start off with 1 cup of antioxidant-rich blueberries. Fresh or frozen, both work well!
Banana: Next, one banana adds sweet, creamy oomph to this recipe. I like using frozen bananas for a frosty consistency.
Yogurt: For consistency, we’ll be using ½ cup of vanilla yogurt. This will add a subtle flavor while also giving the smoothie a thicker texture. You can use your favorite dairy-free version if you’d like.
Milk: Finally, the liquid! I recommend using ½ to 1 cup of milk, depending on how thick or runny you’d like the smoothie to be. You can use a dairy-free option here (like almond milk or your favorite non-dairy milk).

Sarah’s Tip

My favorite way to level up my homemade smoothies is by adding toppings! For this blueberry banana smoothie, I recommend a spoonful of your favorite nut butter, some granola, and some fresh blueberries. It makes the smoothie look like it came from a fancy smoothie shop!

The secret to an epic smoothie

Smoothies are one of those things that always seem to taste better when purchased from a café or smoothie stand… until now.

The answer lies in the frozenness of the ingredients (because nobody likes a runny smoothie). When you use frozen fruit, you’ll wind up with a smoothie so frosty that you’ll be amazed it was created in your own kitchen.

Step 1: Prep the ingredients
Before blending, freeze either the blueberries or the banana. This will give your smoothie a frosty texture! Note: If freezing the banana, be sure to peel and slice it first!

Step 2: Blend everything together
Add the berries, banana, yogurt, and milk to a blender and blitz until smooth. For a punch of healthy fat, you can either blend in nut butter, or use it as a topping! Optionally sprinkle granola on top for some extra crunch.

Customize it!

Like with most smoothie recipes, this one can be customized and tweaked to fit your liking. Here are some options that you can try!

Switch up the fruit
Smoothies are extremely versatile and can be switched up so easily! You can substitute any of the fruit in this smoothie for any fruit you’d prefer. Easy swaps include strawberries in place of the blueberries or mangoes in place of the banana!

Add extra toppings
For extra toppings, you can add nuts, dried fruit, or even chocolate nibs in addition to (or instead of) the nut butter and granola.

Add protein
For a bump in protein, you can actually use cottage cheese in smoothies in place of the yogurt. Don’t worry, the smoothie will still taste like blueberry banana! You could also add a scoop of your favorite protein powder (vanilla flavor works well here), or use high-protein Greek yogurt in place of traditional.

Add veggies
Kick it up a healthy notch by adding a leafy green (like spinach in your smoothie) or cabbage. Cauliflower can also be hidden in smoothies without detection. Or blend in chia seeds, flax seeds, or almond butter for extra boosts of healthy fats.

Sweeten it up
This smoothie is naturally sweet thanks to the blueberries and banana, but you can sweeten it up a little more (especially for the kids or sweets lovers). Add a teaspoon of honey.
