I love oatmeal for breakfast yet sometimes I don’t have time to wait for it to cook. So I’m taking everyone’s staple breakfast and turning it into a filling banana oatmeal smoothie loaded with all the flavors you love in the morning as well as natural energy to get you through your day.

Why this Oatmeal Smoothie Rawks

Wonder if it’s good to have a smoothie for breakfast? A smoothie loaded with wholesome and nutritious ingredients is perfect for breakfast. That’s the key—you need fiber, protein and healthy fats to satisfy, as well as fill you up for hours.

Start your morning off nourished with a thick and creamy banana oatmeal smoothie. It tastes like a delicious oatmeal cookie! Using plant-based wholesome ingredients like oatmeal, bananas, cinnamon, and coconut milk, this is one of the best oatmeal smoothie recipes and the ultimate ‘fast food’ breakfast.

This banana oatmeal smoothie recipe contains banana (shocker!), though the natural sugar from the banana is nicely balanced by the oatmeal and coconut milk to help the body slowly and evenly burn the carbs. #nosugarcrash

Ingredients You’ll Need

In order to make a hearty breakfast, I always start with fresh ingredients. Here’s what I put in my oatmeal smoothie in the morning.

  • Rolled oats: Contribute a subtle nuttiness and a smooth, creamy texture that blends beautifully into the smoothie. For the best flavor, opt for fresh, high-quality oats.
  • Coconut milk: Brings a lush, velvety texture and a hint of tropical flair. Choose unsweetened coconut milk for better control over the sweetness. Here is my guide for the best coconut milk brands—canned and carton or you can learn how to make coconut milk.
  • Frozen banana: Delivers natural sweetness and a luxuriously thick texture. For maximum flavor, use bananas that are fully ripened before freezing. You can see my guide on how to freeze bananas if you need more tips. 
  • Ground cinnamon: Adds warmth and complexity with its sweet and spicy undertones. A pinch can make the flavors pop without overpowering the smoothie.
  • Vanilla extract: Infuses the smoothie with a touch of sweet, fragrant depth. Look for pure vanilla extract for a more robust flavor.
  • Maple syrup (optional): Introduces a gentle, earthy sweetness. Ideal for balancing flavors, use sparingly to enhance without overwhelming.
  • Homemade Protein Powder (optional): I love this blend of hemp, flax, and chia seeds. It adds a natural boost of protein to any smoothie and is great for breakfast.

How to Make a Banana Oatmeal Smoothie

My banana oatmeal smoothie is easy and the perfect breakfast to start the day off right. You can make it any morning with these quick and easy steps.

  1. Put the rolled oats, coconut milk, frozen banana, cinnamon, and vanilla extract into a blender.
  2. Start blending at a low speed to combine the ingredients, then gradually increase to high speed. Blend for about 1-2 minutes, or until the mixture becomes smooth and creamy.
  3. Pour the smoothie into a glass and, for an extra touch, sprinkle a pinch of cinnamon on top or garnish with a few rolled oats.

Easy Swaps and Add-Ins

  • Too thick: If your smoothie is too thick, add a little coconut milk and blend again until smooth. 
  • Too thin: Add another half a frozen banana for a thicker smoothie.
  • Swap coconut milk: If you’re watching your calorie intake, opt for lighter versions of coconut milk. 
  • Add frozen fruit: For a refreshingly cool smoothie, be sure to add at least one kind of frozen fruit.

Health Benefits of a Banana Oatmeal Smoothie

All of the wholesome ingredients in this healthy oatmeal smoothie come together for a healthy and nutritious drink. Aside from the irresistible oatmeal cookie flavor, this healthy recipe offers 3 key benefits:

1. Rich in fiber: While we all know fiber is a good thing, do we know if we’re getting enough fiber each day? According to the US Library of Medicine, only 5% of Americans are getting enough fiber each day. That’s why smoothies are such an important addition to your diet! Blended fruits and veggies give you a great fiber boost to aid in digestion, as well as help keep you regular.

One serving of my banana oatmeal smoothie gives you almost 20% of the recommended daily intake of fiber. So blend up and drink up–your body will thank you later.

2. Healthy Fat: I know, fat isn’t always seen as a good thing. Yet hear me out; your body actually needs healthy fat in order to process your food properly. Check out my guide on healthy fats and how to use them. Without fat, the body does a poor job digesting food, converting carbs into energy, absorbing fat-soluble nutrients like vitamins A, D, E, and K… which are vitally important.

3. Naturally low in sugar: Many quick breakfast options are loaded with extra sugar. While that might make you feel a rush of morning energy, it’s just not sustainable for a busy day. Instead, this banana oatmeal sweet talker with a straw has less than 20 grams of sugar per serving, and balances out that sugar with healthy fat from the coconut milk + fiber from the oatmeal. These ingredients help the body break down the natural sugar, then turn it into usable energy.

Want to help your blood sugar even more? Use a plant-based protein powder, like my homemade protein powder, to give this banana oat smoothie recipe an extra 10 grams of protein + 4 grams of healthy fat. This superfood blend helps keep you full longer, as well as provides more energy.

Common Questions

Can You Put Oatmeal in a Smoothie?

Yes, you can put oatmeal in a smoothie! You get all the benefits of a bowl of oatmeal, yet in a smoothie form. Oatmeal is loaded with fiber, which boosts the good bacteria in your gut. Whether you need an on-the-go breakfast or you crave a refreshing sippable morning meal, this delicious banana oatmeal protein smoothie is a great option.

Can I make a banana oatmeal smoothie without a blender?

While a blender is ideal, you can try mashing the banana and mixing it with finely ground oats, milk, and other ingredients, though the texture may not be as smooth.

What substitutions can I make for a banana oatmeal smoothie?

You can replace bananas with other fruits like mangoes or berries, swap almond milk for dairy milk or other plant-based options, and add protein powder or nut butter for extra nutrition.

How long can I store a banana oatmeal smoothie?

You can store a banana oatmeal smoothie in an airtight container in the refrigerator for up to 24 hours, but it’s best enjoyed fresh for the best taste and texture.

    1. You can add or subtract whatever you want to your smoothie, Beverly! After all, we want these smoothies to work for you. We might recommend a plant-based & unsweetened yogurt, but if Greek yogurt is your preference, that sounds good to us. 🙂
