    • This refreshing smoothie 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.

    Key ingredients and substitutions: 

    • Oat milk: an incredible 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 for this smoothie. 
    • Bananas: the banana helps to make this smoothie sweet, filling, 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 flavor and beautiful light color. You can easily substitute these for your other favourite berries such as strawberries or blackberries. Use either fresh or frozen berries and you could also swap some of the berries to make a cherry smoothie or frozen berry smoothie. 
    • Peanut butter: use your favourite creamy peanut butter or substitute with a natural nut butter, such as almond butter or cashew butter. Be sure to use natural, unsweetened, smooth peanut butter. 

    How to make: 

    Step one:

    To make a smoothie with oat milk, first, 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.

    Chef's tips: 

    • If you prefer a colder smoothie, use a frozen banana, blueberries or raspberries.
    • 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 for this recipe (or another smooth, unsweetened nut butter).
    • Pair this smoothie with some delicious oat milk pancakes!

    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 an oat milk 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. 

    How to store: 

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

    Frequently asked questions: 

    Can I put oat milk in a smoothie?

    Yes! Oat milk is so creamy and works perfectly for making smoothies. 

    Is oat milk or almond milk better for smoothies?

    Both oat milk and almond milk are great for making smoothies. These dairy free milks are plant based and healthy milk alternatives. 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. 

    Is oat milk healthy for weight loss? 

    Yes, oat milk is a healthy weight loss option because it is low in fat, calories, and sugar. To help with weight loss, avoid the sweetened varieties of oat milk, which tend to have added sugars and fats.

    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.
