About this Oat Milk Smoothie Recipe
One of my favorite ways to start the day is by blending up a healthy smoothie recipe.
They’re such a quick & easy way to kick off my mornings with a sippable serving of plant-based goodness, protein, healthy fats and fiber.
So I’m always searching for new flavor combinations to add to my rotation, and this creamy oat milk smoothie is SO good – I knew I had to share it with you asap!
We’re using simple ingredients like frozen bananas, peanut butter, ground flax seed and (of course!) oat milk to create a milkshake-style smoothie that tastes like a total treat.
I honestly love having this smoothie as-is, but it’s so versatile that it lends itself to almost endless variations.
I’ve added lots of customizations & ideas for you so you can use this everyday recipe and make anything from a berry oat milk smoothie to a chocolate or a no-banana version!
Process & Tips
Really all you need to do is add all your ingredients to a blender and let it go to work for you.
Before you know it you’ll be sipping on a delicious, nutrient dense smoothie!
The powerhouse combination of fiber, fat and protein in this smoothie makes it more filling and satiating than your typical smoothie.
Plant-powered fiber comes in the form of the frozen banana and ground flax seed.
Healthy fat comes in the form of the ground flax seed, peanut butter and oat milk.
And the protein can be found in the peanut butter as well as the protein powder.
How to Make an Oat Milk Smoothie Bowl
You can also turn this recipe into a smoothie bowl by making the smoothie thicker using only 1 1/2 cups of oat milk.
Also, make sure to use frozen bananas to help you get that thick consistency.
Once blended, pour into a bowl and add your choice of smoothie bowl toppings.
Some fun topping ideas would be nuts, seeds, sliced fresh fruit, granola, honey, cacao nibs and a drizzle of almond butter.
Why Would You Use Oat Milk in a Smoothie?
Naturally dairy-free, oat milk adds a creamy consistency and (in my opinion) is the creamiest plant-based milk – making it a great option for smoothies!
It can also be a good alternative for those looking for a nut-free plant-based milk option.
Tip: Not all oat milk is gluten free or nut free. Be sure to check labels and ingredients lists to ensure the milk is gluten-free & nut-free if that’s important to you!
Fun Variations to Try
No banana oat milk smoothie: Substitute in 1 cup of frozen riced cauliflower in place of the banana and (optional) 1-2 tablespoons of maple syrup to replace the creamy texture & sweetness of the banana.
Berry oat milk smoothie: Add one cup of fresh or frozen mixed berries of choice.
Cherry oat milk smoothie: Add one cup of fresh or frozen pitted cherries.
Raspberry oat milk smoothie: Add one cup of fresh or frozen raspberries.
Chocolate oat milk smoothie: Use chocolate protein powder in place of vanilla protein powder and add 1-2 tablespoons of unsweetened cocoa powder (or cacao powder).
Green oat milk smoothie: Add a handful of baby spinach or kale to the blender for an extra boost of greens.
Ingredients & Modifications
Unsweetened oat milk: Since it’s the star ingredient of this smoothie, I used unsweetened oat milk for this recipe but any milk will work great in its place too. Including almond milk, cashew milk, coconut milk or hemp milk. If you like a thinner consistency in your smoothies, add more milk.
Frozen banana: You can also use fresh banana in place of frozen banana in this recipe. It adds some natural sweetness and banana flavor to the smoothie.
Unsweetened peanut butter: I like unsweetened peanut butter in this smoothie but you can use any other type of nut butter (like almond butter) that you like in its place. For a nut-free option, be sure to use sunflower seed butter.
Ground flax seed: Ground flax seed adds a bit of fiber and a dose of plant-based protein. I find it easier to use ground flax seed but you could also add whole flax seeds if you have a high speed blender. Chia seeds would also be an easy substitution for flax seeds in this recipe.
Vanilla Protein Powder: You can use any protein powder you like the taste of. To keep this recipe paleo friendly, be sure to use a grain-free and dairy-free protein powder. To keep this recipe vegan friendly, be sure to choose a vegan protein powder.
Tip: If using fresh bananas in place of frozen, be sure to add extra ice to the blender for better texture.
