Creamy Oat Milk Smoothie (w/ Protein)
Rich and creamy, this easy oat milk smoothie combines banana, peanut butter and oat milk for a wholesome way to start your day. A naturally sweet protein shake, it’s perfect for breakfast and ready in just five minutes!
An Oat Milk Protein Smoothie Ready in Minutes
One of my favorite ways to start the day is by blending up an easy smoothie recipe. They’re such a quick & easy way to kick off my mornings with a sippable serving of feel-good ingredients. 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 protein smoothie that tastes like a total treat. I honestly love having this oat milk protein shake 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 oat milk breakfast smoothie and make anything from a berry oat milk smoothie to a chocolate or a no-banana version!
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.
Tip: Some fun topping ideas would be nuts, seeds, sliced fresh fruit, granola, honey, cacao nibs and a drizzle of almond butter.
Oat Milk is a Dream In Smoothies
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.
- No peanut butter: Swap in almond butter or sunflower seed butter.
Ingredients & Modifications
- Unsweetened oat milk: Since it’s the star ingredient of this smoothie, I used unsweetened oat milk for this recipe. 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: 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.

Delicious and super creamy!! I’m adding some actual oats in the next one. Can’t get enough oat-y-ness for me 🙂
Robyn, great idea! I actually tested this one with oats and loved the flavor, plus the boost of fiber and even protein the whole rolled oats add. I ended up not using them in the final recipe because the texture is a bit off unless you have a true high speed blander to get it to the lovely creamy state. But I think adding a handful to your next smoothie is a great idea. Thanks so much for leaving a review!
