    Why you will love this recipe: 

    • The taste! This smoothie is so good and refreshing. The combination of fresh berries, ripe banana, oat milk, and creamy peanut butter blend perfectly to give this smoothie the best flavour.
    • This smoothie is quick and easy to make with just 5 ingredients. You can meal prep it the day before and take it with you in the morning for an easy on-the-go breakfast.
    • This smoothie recipe can be customized with any fruit and add-ins of your choice. Change it up and make a cherry oat milk smoothie, frozen berry oat milk smoothie or raspberry oat milk smoothie.
    • It is naturally sweetened and is healthy, vegan, egg free, dairy-free, and gluten-free. 
    • This healthy smoothie is the perfect breakfast, snack, or after-workout shake.

    If you love smoothies you will also love cherry smoothie, key lime pie smoothie, watermelon and banana smoothie and my berry lemonade smoothie recipe.

    Ingredients and substitutions: 

    • Oat milk: The base of this creamy smoothie, oat milk is a non-dairy milk that has a nice sweet flavour. Use plain or unflavoured oat milk for this recipe to avoid any added sugars. You could also use your own homemade oat milk.
    • Bananas: the banana helps to make this smoothie sweet, smooth, and creamy. If you prefer a smoothie with no banana, omit the banana and add more berries or other fruit instead. You could also use frozen banana for this recipe. 
    • Berries: both blueberries and raspberries are used in this recipe to give it an incredible flavour and beautiful colour. You can easily substitute these for your other favourite berries such as strawberries or blackberries. Use either fresh or frozen berries. 
    • Peanut butter: use your favourite creamy peanut butter or substitute with another natural nut butter such as almond butter or cashew butter. Be sure to use natural, unsweetened, smooth peanut butter. 

    How to make (step-by-step): 

    Step one:

    Put all the ingredients into your blender and blend until smooth.

    Step two:

    Next, pour the smoothie into a large glass and enjoy! Serve immediately or store it in the fridge until you are ready to drink.

    Top tips: 

    • If you prefer a colder smoothie, use a frozen banana, frozen blueberries or frozen raspberries to make this smoothie.
    • I recommend using plain, unsweetened oat milk for this recipe. 
    • If you like a thicker smoothie, add a little yogurt or decrease the amount of oat milk you add. 
    • I recommend using smooth, unsweetened peanut butter (or another smooth, unsweetened nut butter).

    Variations and add ins: 

    • Add some protein powder or collagen peptides to this recipe to turn it into an oat milk protein shake. 
    • Feel free to swap the berries for other berries  or fruit including strawberries, or blackberries. You can also use frozen berries or even cherries!  
    • To make a green smoothie with oat milk add a handful of spinach or kale.
    • If you prefer a smoothie with no banana, omit the banana and double the amount of berries in the recipe. 
    • To make this smoothie gluten-free, be sure that the oat milk you are using is certified gluten-free. 
    • You can easily double or triple this recipe if you are serving more than one person or want leftovers for meal prep.

    How to store: 

    If you don't drink this smoothie right away it stores well in the fridge overnight. 

    This smoothie also freezes really well for up to 3 months.

    Frequently asked questions: 

    Is oat milk or almond milk better for smoothies?

    Both oat milk and almond milk are great for making smoothies. Which one is better will depend on your taste preference. Oat milk is a little sweeter than almond milk and higher in carbohydrates will almond milk is less sweet but higher in fat. 

    How many calories does this smoothie have? 

    This smoothie recipe has 495 calories per serving, including 15 grams of protein and 13 grams of fiber. 

    What makes a smoothie unhealthy? 

    The easiest way to make a smoothie unhealthy is by adding a lot of sugar. Refined sugars are linked to many different health problems including heart disease, weight gain, diabetes, strokes and liver disease. To keep your smoothies healthy stick to ingredients like fruits and vegetables and avoid adding any extra sugars or sweeteners.
