    🧾 Ingredients

    Banana Oatmeal Breakfast Smoothie measured ingredients
    • Rolled oats, steel-cut oats, or quick oats: These oats are the foundation of your smoothie, providing heart-healthy fiber and giving it a creamy texture. Plus, oats are a great source of vitamins, minerals, and antioxidants.
    • Frozen banana: This not only chills your smoothie but also adds natural sweetness and a silky texture. It's the Hulk of fruits, packing potassium and vitamin C while keeping sugar levels in check.
    • Creamy peanut butter: Adds a decadent, nutty flavor while delivering a punch of protein and healthy fats. Think of it as the smoothie's VIP, offering not just taste but also nutritional richness.
    • Ground cinnamon: A sprinkle of this spice ramps up the flavor profile and comes with antioxidant benefits. It's like your grandma's warm hug, but for your insides.
    • Chia or flax seeds: These little guys are the unsung heroes, offering Omega-3 fatty acids and additional fiber. They're basically the backup dancers that deserve a solo, supporting both heart health and digestion.
    • Oat milk: This dairy-free milk complements the oats, making your smoothie even creamier. Plus, it's environmentally friendly and adds calcium and vitamin D to the mix.

    Optional: maple syrup, ground turmeric, and a pinch of pepper.

    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.

    Step 1: 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.

    Step 2: 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.

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

    💡 Expert tips

    Use ripe bananas for the best sweetness and texture. Ripe bananas not only add a natural sweetness, reducing the need for added sugars, but they also blend into a creamier consistency, making your smoothie rich and smooth.

    Adjust the thickness to your liking by playing with the amount of plant milk. Start with the recipe's recommended amount of plant milk, and then, add more if you prefer a thinner smoothie or less for a thicker consistency. Remember, the smoothie will also thicken slightly if you let it sit for a few minutes after blending.

    Add a pinch of cinnamon or vanilla extract for an extra flavor boost. These ingredients can complement the natural sweetness of the banana and the nuttiness of the oats, elevating the overall taste of your smoothie without overwhelming it.

    Freeze your bananas ahead of time for an extra cold and refreshing smoothie. Using frozen bananas not only chills your smoothie without the need for ice (which can water it down) but also contributes to a creamier texture, making your smoothie feel more like a treat.

    store your Banana Oatmeal Breakfast Smoothie in a closed mason jar

    📖 Variations

    Oats Variety: Feel free to use old-fashioned rolled oats, steel-cut oats, or quick oats. For a gluten-free option, opt for certified gluten-free oats.

    Weight Loss Option: For a lighter version, omit the peanut butter, use a no-calorie sweetener, and half a banana for a reduced-calorie yet naturally sweet smoothie. The oats' fiber will help keep you full.

    Energy Boost: Add Maca root powder for enhanced energy and stamina, ideal for supporting your workout routines.

    Plant Milk Choices: Any plant milk suits this smoothie. Favorites include oat milk and homemade almond milk, but soy or coconut milk are great too. Each adds a unique flavor, with coconut milk giving a distinct taste.

    Nut Butter: Incorporate any nut butter (peanut, almond, cashew, hazelnut) for healthy fats and satiety. For those looking to gain weight, this is an excellent addition, especially combined with weightlifting.

    Sweeteners: Bananas provide natural sweetness. If you prefer a sweeter smoothie, consider adding maple syrup, pitted dates, or agave syrup instead of refined sugar.

    Chocolate Twist: Add a tablespoon of dark chocolate powder or vegan chocolate bits for a chocolatey version. Vanilla extract is also a nice touch.

    Seeds: Boost nutrition with chia, flax, or pumpkin seeds for added fiber, protein, antioxidants, and omega-3 acids. For enhanced nutrient absorption, grind seeds and store them in an airtight container in the fridge.

    Spices: Enhance flavor without calories by adding spices like cinnamon, pumpkin pie spice mix, cloves, nutmeg, allspice, cardamom, or turmeric. Include a pinch of black pepper to activate turmeric's benefits.

    Creaminess: For extra creaminess without dairy, add two tablespoons of vegan yogurt (vanilla, coconut, or plain). Soaking chia seeds and oats overnight will also increase smoothie thickness.

    🥤 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 mixed berry smoothie, or a simple grapefruit smoothie, to give our bodies a boost of antioxidant low-calorie goodness.

    Ingredients
     
     

    • ¼ cup oats rolled, steel-cut oats, or quick oats
    • 1 banana ripe, frozen
    • 1 tablespoon peanut butter or almond butter, nut butter
    • ½ teaspoon cinnamon ground, or pumpkin pie spice
    • 1 cup oat milk or hazelnut milk
    • 1 tablespoon chia seeds or flax meal

    Optionals (good as is it is, but these are some recommended twists)

    • 1 tablespoon date paste or maple syrup, agave syrup, or 1 medjool date
    • ¼ teaspoon ground turmeric
    • pinch black pepper
    • 1 cup ice cubes if banana is not frozen
    • 2 tablespoons vegan vanilla protein powder
    • 3 teaspoons maca powder for enhanced energy and stamina
    Prevent your screen from going dark

    Directions
     

    • Freeze the banana overnight, or at least 30 minutes before cutting it into slices.
    • Grind rolled oats. If using old-fashioned rolled oats, optionally grind them in your blender, pulsing it for a few seconds, so you make an oatmeal flour. This will ensure you have an even creamier smoothie. If you like some grits in your smoothie, skip this step.
    • Blend. Add everything into a high-speed blender. If using rolled oats and prefer a creamier consistency, first pulse the oats in the blender, without any liquid, to make an "oats flour"; then add the rest of the ingredients, and blend for 40 seconds or over your blender's smoothie mode.
    • Serve Cold.
      Smoothie leftovers will keep in a covered mason jar in the refrigerator for up to 2 days, though best when fresh.

    Notes

    Nutrition facts are calculated without the protein powder.
    Adding the suggested protein powder adds 28 calories, 0 carbohydrates, and 5 grams of protein per serving.
    Add agave or maple syrup for extra sweetness or extra dates. We like using dates because they have a ton of beneficial post-workout benefits.

        Hey Saif,

        So glad you enjoyed the oat milk smoothie! You're absolutely right—cinnamon and banana are like the dynamic duo of the smoothie world, aren't they? They elevate pretty much any cold drink from good to "can't-stop-sipping" level. Thanks for giving our recipe a spin and sharing your thoughts!

        Best,
        Gus & Joaco
