This easy, healthy chocolate smoothie is made with banana, almond butter, rolled oats, flax seed and a scoop of chocolate protein powder. It’s such an easy, healthy breakfast smoothie or snack idea. Recipe is vegan, gluten-free, delicious, and ready in 5 minutes.

I enjoy VERY thick smoothies and after drinking freezing cold shakes with a ton of ice in them (or upwards of 2 whole frozen bananas lol), I eventually figured out that you can use a scoop of oats for thickness in my breakfast smoothie as well! This is a win for those times when I crave the convenience and goodness of one of my healthy vegan smoothies, but am preferring a less ice-cold experience. If you’re looking for even more vegan smoothies and wholesome vegan meals, check out my cookbook as well.

I love big salads, fresh juices, and of course smoothies all year. I especially love adding oats to my blended concoctions now because it gives the smoothie that cozy oat flavour. It also makes the drink extra filling. Of course I had to make this one chocolate-y and of course I give you a load of options for customizing too! Get this chocolate banana oat breakfast smoothie in your life!

How To Freeze Bananas for Smoothies:

  1. Wait for the bananas to get perfectly speckled on the outside and ripe.
  2. Line a baking sheet with parchment paper and clear a space in your freezer.
  3. Peel the bananas and chop them into 2-inch pieces
  4. Place the chopped bananas pieces in a single layer on the baking sheet.
  5. Place the baking sheet in the freezer and freeze the chopped bananas until solid, or overnight.
  6. Transfer frozen banana pieces to a resealable bag or airtight container (to save space in your freezer).
  7. Use bananas within 6 months of freezing.

The main thing that I love about this smoothie is that I pretty much always have these ingredients on hand (same goes for my ultra filling fiber smoothie). I keep a big stash of frozen, chopped bananas in my freezer, and almond butter, flax seeds, and vegan protein powder are pantry staples for me. The frozen bananas are so key! They make smoothies super frothy, thick, and creamy.

This smoothie can easily be made nut-free! Simply use an oat or soy-based milk, and swap in tahini or pumpkin seed butter for the almond. Also, if you like this smoothie, I bet you’ll also be into my Peanut Butter Vanilla Green Shake, another delicious breakfast smoothie option! My Spinach Banana & Ginger Smoothie is another favourite for getting the day started.

Prep Time: 5 minutes
Total Time: 5 minutes
Servings 1


  • 1 cup non-dairy milk
  • ¼ cup rolled oats
  • 2 tablespoons almond butter (or other nut/seed butter)
  • 1 ½ tablespoons unsweetened cocoa powder
  • 1 teaspoon flax seeds
  • ¼ teaspoon vanilla extract
  • 1 large ripe banana, preferably frozen
  • pinch sea salt
  • pinch ground cinnamon
  • 1 scoop chocolate protein powder optional
  • ¼ cup ice optional



  • Feel free to add a pitted medjool date to this mix if you prefer your smoothies a bit sweeter!
  • Other additions that are great in this smoothie: a handful of mild greens like baby spinach, chia seeds (1 teaspoon), even a handful of an alternative smoothie thickener like frozen zucchini or cauliflower is amazing. Chocolate fixes all!


  • In an upright blender, combine the non-dairy milk, oats, almond butter, cocoa powder, flax seeds, vanilla, banana, salt, cinnamon, protein powder (if using), and ice (if using). Put the lid on and bring the blender speed up to high. Blend until the smoothie is totally smooth and frothy. Enjoy immediately!

  • Jill

    I’m drinking this now – delicious!

  • Matthew

    How many people does this serve?

    • Laura

      Hi Matthew,
      It is 1 serving. Near the top of all of my recipes, you’ll see a “Servings” heading.

  • Edward Parker

    This definitely looks delicious and I love smoothie. Thanks for sharing

  • Polina

    I’ve seen these type of tall round glass cups before and they’re so cute! Where did you buy them?

    • Laura

      This glass was actually a promotional gift from a brand that I worked with a long time ago! It doesn’t have the manufacturer’s name on the bottom unfortunately. Wish I could help!

  • Sandra Lea

    I am obsessed with this smoothie and have made it quite a few times now. The only change I made was to use 1 tablespoon of chocolate, the first time I made it the chocolate was a little overpowering. Thanks for a great recipe.

  • Anneline

    I’m not a fan I’d smoothies but this one just called out to me. I just made it (with all room temp ingredients though) and it is delicious! It has such incredible chocolate taste! Thank you, I’ll definitely make it again!

  • Jodie

    Hands down the best smoothie I’ve ever made. Thank you! Ticked off a ton of pregnancy nutritional requirements and made this pregnant lady very happy!

    • Laura

      So glad you enjoyed it, Jodie! :)

  • christiane

    Made it this morning as a snack since my 3 years old son was asking for chocolate. Made as is without the ice and it is absolutely delicious!!!
    yum, the banana is sweet enough so I did not need to add any dates or other sweetener. It sure satisfies my sweet tooth in a healthy way.

  • Katrina Newman

    Do you think you could lose the banana altogether? I’ve never liked them.

    • Laura

      Hi Katrina! See my suggestions to Jacquie above. Helen’s suggestion of avocado is also great! You may want to add a date or something to adjust for the sweetness there.

  • jacquie

    Hi – that shake looks so great but i don’t use banana’s. Is there something i can use as a substitute?


    • helen

      maybe try some avocado

    • Laura

      In the recipe notes I suggest frozen cauliflower or zucchini. You may have to add a date or something similar to sweeten it up. If you’re up for it, cooked and then frozen sweet potatoes substitute beautifully for bananas (if you like the taste). I also love diced frozen pear as a smoothie thickener and I think it would work well here. I’ve heard of people using firm tofu as a thickener for smoothies as well!

  • Kathryn Mader

    Am drinking this as I type. Delicious! Thank you because I love nothing better than a chocolate smoothie.
