    Salty, nutty, and sweet. This peanut butter banana smoothie is such a pleasure, it could almost be dessert.

    Vegan, gluten-free, and soy-free.

    A peanut butter banana smoothie is flawless in its simplicity.

    A perfect combination with nothing to stand in its way.

    When you don’t want anything to distract from the joy that is PB & banana coming together, this is the smoothie you need.

    The salty nuttiness of the peanut butter mellows the gentle sweetness of the banana.

    Frozen bananas are a must

    When it comes to smoothies, frozen bananas are essential.

    You could just throw a banana into the blender right after peeling.

    But giving the banana time to freeze solid means that the smoothie will have a wonderfully creamy texture that it wouldn’t get otherwise.

    It pushes the smoothie almost into shake category.

    To freeze bananas, peel them first. Break them into chunks. Then freeze in a freezer safe resealable bag or glass container.

    When you’re ready to use the frozen banana, just pull out as many pieces as you need.

    Ingredients

    Here are the ingredients you will need to make this recipe.

    Labeled ingredients for peanut butter banana smoothie.

    Non-dairy milk: I usually use cashew milk. However, you can use any non-dairy milk you enjoy like almond milk or soy milk.

    Bananas: For the best flavor & texture, use ripe bananas that have been peeled & frozen in chunks.

    Peanut butter: You can use crunchy or smooth peanut butter.

    I recommend peanut butter that doesn’t contain added oils or sweeteners. Look for brands that only contain the ingredients of peanuts & maybe salt.

    Peanut butter can be replaced with any nut or seed butter that you enjoy.

    Flaxseed: You can use whole or ground seeds.

    However, ground flaxseed is the most convenient if you don’t have a high-speed blender (that can easily grind them).

    Flaxseed can be replaced with chia seeds or omitted.

    Step by step instructions

    Here’s how to make this recipe at a glance. For complete ingredient amounts & instructions, keep scrolling to the recipe card below.

    Overhead blender jar with peanut butter, banana chunks, flaxseed, and non-dairy milk.

    Blend the following in a high-speed blender until smooth:

    • Non-dairy milk
    • Frozen banana chunks
    • Peanut butter
    • Ground or whole flaxseed

    If you’re not using a high-speed blender, you’ll need to grind the whole flaxseeds first in a clean coffee grinder, or use ground flaxseed.

    (Remember to store opened bags of ground flaxseed in the refrigerator.)

    This peanut butter banana smoothie recipe makes enough for two small drinks.

    Even though they’re on the diminutive side, they’re quite filling with the PB & flaxseed inside.

    Or you can enjoy it in one tall glass.

    Make it your own

    Make this smoothie your own by varying the ingredients:

    • Use any non-dairy milk you prefer in plain or vanilla – cashew, soy, oat, or almond milk
    • Try it with a different nut butter like cashew, almond, walnut, or pistachio butter
    • Replace flaxseed with chia seeds or omit it altogether

      The smoothie of course looks delicious—great idea to add the flax for texture and consistency! Plus healthy! My boys would love this, and we have a great nut free peanut butter sub that would be perfect!

        Thanks, Sarah! When it comes to smoothies, I always add chia or flax. I love that whippy viscosity that they give. That’s a great idea to do a peanut butter sub for your boys. You’ll have to let me know if you try it!

      Bananas in smoothies are MUST for me. A smoothie just isn’t a smoothie without one. And a PB & Banana Smoothie is basically perfection in a glass. You’re making me crave one right now.

        I totally agree about bananas being essential to a smoothie. Plus, it seems like the other option is avocado for creaminess and body. Avocados are way too pricey & delicious to be hiding in a smoothie. Last week when I was creating/photographing this recipe, I had a PB & banana smoothie 3 days in a row. No complaints! 😀

      I will second your thoughts on frozen bananas for smoothies. This is one of the many tricks you’ve taught me over the years for which I’m very grateful!

        I’m glad I was able to convert you to the frozen banana side. Whenever I hear that people are still using room temperature bananas for smoothies, I feel a little sad for what they’re missing! 😀
