🔪 Instructions

This peanut butter oatmeal smoothie is packed with healthy ingredients like oats, almond milk, and bananas, which will give you sustained energy throughout the morning.

Plus, it's super easy to make - just blend all of the ingredients together and enjoy!

Freeze bananas overnight.

If you don't like grits in your breakfast smoothie, I recommend you use quick oats, or add your rolled oats to the blender and pulse them a couple of times to grind them while they are still dry.

In general, when making a banana oat smoothie, if you use extra ripe frozen bananas you can skip the maple syrup, homemade date paste, or dates.

Measure your ingredients.

If you are using fresh bananas, you can stir in a few ice cubes or other frozen fruit like strawberries or blueberries to ensure the smoothie is chilled.

Blend all your ingredients, including the frozen bananas, rolled oats, peanut butter, seeds, spices, maple syrup, and oat milk, in a high-speed blender for 40 seconds or until you achieve the desired consistency.

Hint: reduce the almond milk quantity to half for a thicker smoothie. For a thinner smoothie, you can add more plant milk or water if you want to keep the calorie count equal.

That's it! Thick and creamy smoothie! Serve immediately.

If you want to make, your oatmeal banana smoothie prettier, add some ground cinnamon, creamy peanut butter, or oats on top.

🫙 Storage

We always make a Banana Oatmeal Peanut butter Smoothie in Batches.

It just saves time, and it is an easy way to have something super nutritious just after our morning yoga routine, that is packed with protein and antioxidants, and keeps us full until lunchtime.

Store your leftover smoothie using an airtight container or a mason jar and reserve it in the refrigerator for up to 3 days.

📖 Variations

This banana oatmeal smoothie can be made with oats, from old-fashioned rolled oats to steel-cut oats and quick oats.

If you follow a gluten-free diet, make sure to look for certified gluten-free oats (affiliate link), as oats do not contain gluten in their natural form.

If you suffer from celiac disease or experience gluten sensitivity, oats are regularly processed in facilities that handle products containing gluten.

Remember that oats are great additions to any healthy breakfast, as they keep you full and satiated; try them on your breakfast fruits bowls.

Oats smoothie for weight loss

You can easily make this oats smoothie recipe for weight loss, simply removing the peanut butter, using a no-calorie sweetener, and using half banana so you can still enjoy a naturally sweetened smoothie with a minimum calorie intake.

Still, the insoluble fiber from the oats will do its work to keep you fuller for longer, enjoying the weight loss promoter benefits of a smoothie with oat milk.

Adding Maca root powder to enjoy its greater energy (affiliate link) and stamina benefits is also a great idea because you will be able to endure more during your weight loss workouts.

Dairy-free milk

All types of plant milk work for this smoothie. We use them indistinctively. If we have oat milk or homemade almond milk handy, those are usually our go-to options, but even homemade soy milk, or coconut milk, are fine.

Coconut milk is the one where you will definitely feel a stronger different taste, but it is equally delicious.

We love making our own plant kinds of milk because they are hassle-free to make, cheaper, yummier, and more environmentally friendly.

They are both great for savory preparations like a vegan bechamel sauce and creamy vegan dips.

Nut butter

Adding any nut butter as part of a healthy breakfast smoothie, such as peanut butter, almond butter, cashew butter, or even hazelnut butter, is a great idea, as they contain healthy fats that will keep you fuller for longer without the saturated fat.

Having an oatmeal peanut butter smoothie is a great option if you want to use this oats smoothie for weight gain.

If you plan on lifting weights (affiliate link) to support your weight-gaining goals, using maca powder can also be a great addition to your smoothie.

Maple syrup

Bananas are naturally sweet, and I don't really love having too many sweets in the morning.

Ripe frozen bananas work for me on this recipe, but many people, including Joaquin, prefer sweeter smoothies.

If you are one of them, add the maple syrup, or use another natural sweetener like pitted dates or agave syrup.

Just don't use any added sugar that doesn't bring anything to your healthy game!

Keep in mind, that just as in a loaf of banana bread, using blackened or ripe bananas, can drastically change how sweet your banana oatmeal smoothie recipe is.

Chocolate oat smoothie version

This nutritious oatmeal smoothie, with its delicious banana flavor, warm oats and cinnamon, and the delectable taste of peanut butter, has a chocolate chip cookie-like flavor.

Although this banana oatmeal smoothie doesn't have chocolate chips, you could certainly add a tablespoon of dark chocolate powder or even add some vegan chocolate grits on top.

You can also add pure vanilla extract to the banana smoothie.

Seeds

Yes, everyone is crazy about chia seeds, but other seeds like flax seeds and pumpkin seeds are equally nutritious.

Seeds add fiber, protein, antioxidants, and healthy omega-3 acids to your meals. Feel free to add a flax meal, for a change.

If you want to make the best out of the nutrition of your seeds, leave them soaking in almond milk or water overnight, or 10 minutes before blending your banana oatmeal smoothie. This will further activate their properties.

Also, blending your chia seeds and flax seeds together is a good idea, using a regular food processor (affiliate link) or immersion blender (affiliate link).

Keep the seeds ground in an airtight container in the fridge, so you can simply add the powdered superfood into your smoothies and salads.

This makes the nutrients to be more readily available to your body, as the gastric juices in our stomach cannot easily break the seed's membranes.

We always add some sort of seeds into our banana oatmeal smoothie; it is just a very easy way to boost its nutritional value!

Spices

We love adding spices to our smoothies because they have no calories but are packed with benefits, minerals, and precious nutrients.

They are also packed with flavor, so you just need to add very small amounts.

One easy way to add a nice variety is by substituting the cinnamon powder for the same amount of pumpkin pie spice mix.

Or you can add your preferred spices such as cloves, nutmeg, allspice, and cardamom in small amounts (⅛ teaspoon).

I always add some turmeric because it is a superfood that is easily added to both sweet and savory dishes and packs lots of anti-inflammatory properties.

Always add a pinch of black pepper to activate even further its properties. It's natural chemistry!

Make it even creamier!

Many vegetarian smoothies include plain Greek yogurt, but we know now that dairy foods aren't the healthiest, and some people even suffer from lactose intolerance.

If you want to add extra creaminess or tartness, you can add two tablespoons of vegan vanilla-flavored, coconut-flavored, or plain yogurt.

Leave your chia seeds and oats soaking overnight together, and they will be even thicker and creamier when you add them to your smoothie, just as you would make lemon blueberry or pumpkin overnight oats.

More fiber and antioxidants

You can add even more fiber to your banana oat peanut butter smoothie; adding more frozen fruit like frozen strawberries or mixed frozen berries will make the smoothie even more nutritious.

You can even add ½ cup frozen spinach if you want to add some greens and level up your nutritional intake.

Another option is to double your oatmeal quantity.

You will end up with a thicker smoothie, and you may want to adjust with a ⅓ cup of water or almond milk.

Protein shake with oats and peanut butter

We often have this banana oatmeal smoothie as our post-workout drink. It has everything you need to replenish your body after exercise; just make sure you use good quality protein powder.

If you are lifting weights, looking forward to using this smoothie with oat milk for weight gain, and need an extra protein intake, adding a clean plant-based protein powder is a great idea. We like complement organic protein (affiliate link).

We like using the compliment brand because they use only clean and natural ingredients on it, and you can add it to virtually any smoothie and even to sweet recipes like banana bread.

The smoothie tastes absolutely delicious.

🥤 More nutritious smoothies

Our favorite recipes are those that are not only delicious but very nutritious.

Banana and oatmeal smoothies are at the top of the list, along with post-workout smoothies, when we think about replenishing our energies after yoga or lifting weights.

When we think about refreshing summer smoothies, our minds immediately switch to mango smoothies, pineapple coconut smoothies, strawberry pineapple smoothies & strawberry-banana smoothies.

On the other hand, when we are on cleansing days, we tend to drink superfoods-based detox smoothies, frozen berries smoothies, or a simple grapefruit smoothie, to give our bodies a boost of antioxidant low-calorie goodness.

Lastly, if you love super-rich but still healthy desserts, don't forget to check our peanut banana ice cream version of this banana smoothie which we absolutely love, and it is put together only with a blender plus 5 minutes of your time.
