Mamas, you will love this chocolate banana lactation smoothie! It tastes amazing and has oats, flaxseed and brewer’s yeast to help boost your milk supply.

As a breastfeeding mama I’m always looking for ways to increase (or maintain) my milk supply.

Glass jar with chocolate banana smoothie topped with cacao nibs and a peanut butter drizzle.

I’ve developed recipes for lactation cookies and lactation bites, which I love. They’re both super tasty and I definitely notice a difference in my supply when I eat them regularly, but there are plenty of days where I’ve run out of the cookies/bites and I need something fast… that’s where this lactation smoothie comes in.

How to Make a Lactation Smoothie

You can literally make any smoothie a lactation smoothie just by adding specific milk producing foods, but haphazardly adding ingredients to a smoothie can often times result in a concoction that doesn’t taste so good. Especially when you’re working with a bitter ingredient like brewer’s yeast. Been there, done that!

This smoothie on the other hand, has three ingredients for boosting your milk supply (oats, brewer’s yeast and flaxseed) and it still tastes delicious.

It’s so good, I would happily drink it daily even if I wasn’t nursing/pumping. The combo of banana, chocolate and peanut butter totally masks the bitter taste of the brewer’s yeast and the frozen fruit combined with the oats and flaxseed give the smoothie a thick and creamy texture.

Sweetened With Medjool Dates

I purposely chose to sweeten this smoothie with medjool dates because I figured many mamas will have a few leftover from endlessly eating dates to help prep for labor. If you don’t have any dates on hand, you can use another natural sweetener like maple syrup or honey. I’d start with 1 teaspoon, taste the smoothie and add more if needed.

Ingredients in This Lactation Smoothie

Since breastfeeding Olivia, I’ve done a bit of research about which foods are best to keep your milk supply up and help with milk production. Here’s a little list of the foods I found:

  • banana
  • almond milk
  • medjool dates
  • brewer’s yeastbrewer’s yeast is packed with vitamin B, iron, zinc, magnesium and potassium. It can be hard to find in stores so I purchased mine from Amazon.
  • oats – oats are high in iron and some studies have shown that oats help with milk production.
  • ground flaxseed – flaxseed is high in omega-3 fatty acids (which are great for baby) and it also contains phytoestrogens that can influence breast milk production.
  • peanut butter – there’s not better combo than chocolate and peanut butter, but feel free to use your favorite nut butter here. Cashew butter or almond butter would both work great.
  • cocoa powder – this is where the chocolate flavor comes from
  • ground cinnamon – this adds a touch of sweetness without any additional sugar
  • frozen cauliflower rice – this is optional, but I love the thickness it adds to smoothies.

I’ve been making this smoothie for breakfast or lunch. It’s filling enough to have on its own as a meal, but sometimes I’ll pair it with a little something extra like a hard boiled egg. I love the flavor and it’s been helpful for my milk supply as well. I hope you like it as much as I do.

Chocolate Lactation Smoothie

This chocolate banana lactation smoothie tastes amazing and has oats, flaxseed and brewer’s yeast to help boost your milk supply.
Prep Time: 5 minutes
Total Time: 5 minutes
Servings: 1



  • Add all of the ingredients to the blender in the order they’re listed. Start with 1 medjool date. You can add the the second if the smoothie isn’t sweet enough.
  • Cover and blend on high until smooth. Pour into a glass and enjoy.
  • I topped the smoothie with an extra drizzle of peanut butter, banana slices and cacao nibs, but toppings are optional and I only recommend adding them if you plan to eat the smoothie with a spoon.


  • If you don’t have dates you can use maple syrup or honey as a sweetener. Start with 1-2 teaspoons and add more if needed.
  • The frozen cauliflower rice is optional, but I like adding it to my smoothies to make them a bit thicker and to get some veggies in.

    Another hit! I was looking for another way to supplement my milk supply outside of bites and cookies – and this was a delicious swap. Honestly, even If I wasn’t nursing I’d drink this! You can’t even taste the brewers yeast!

    1. Yay!! So glad you enjoyed this smoothie, Rema. 🙂 Thanks for giving it a try and for coming back to leave a comment + Star rating. I really appreciate it.

    1. So glad you enjoyed this smoothie, Jennie! I tested the recipe several times to make sure the brewer’s yeast flavor was hidden. 🙂 Thanks for making it and for coming back to leave a comment + star rating. I appreciate it!

    I haven’t tried this yet, I see you say there is flaxseed one it but it’s not in the ingredients list. How much flaxseed do you add? Whole or ground?

    1. Hey April – Thanks for catching that! It should be 1 T of ground flaxseed. I just updated the recipe. 🙂

      1. 5 stars
        Awesome!! Thank you. I tried it out today and enjoyed it. It’s going to go into rotation for post baby .

  4. Could you use stevia in this instead of dates or honey? I have all the other ingredients on hand and would love to give this a try, but want to make sure the brewer’s yeast doesn’t taste gross!

    Loving your website!!! I finally made time to make this smoothie. Since I didn’t have a frozen banana, I added ice and it seemed to be ok. My only mistake was not removing the pit/seed from the date! And I think I added a little too much cinnamon. I’ll need to give this another try. I already placed a banana in the freezer and will comment on the second results soon.

    1. Thank you, Julie!! Oh no, yes definitely take the pit out of the date before blending! Keep me posted how the second time making this smoothie goes. 🙂

    WOW! What more can I say?! This smoothie is super yummy, and packed with nutrients!! I’m not a mother, so I left out the brewer’s yeast and it still tasted amazing!! If you aren’t a mom either, don’t hesitate to try this smoothie! Super filling and satisfying! Thanks Brittany!

    1. Yay!! I’m so glad this smoothie was a hit, Taylor! I appreciate you trying it and coming back to leave a review. Thank you so much!!

    Super tasty! I’ve used kale and spinach in smoothies before, but never thought to try cauliflower…great choice to add veggies while not changing the flavor of the smoothie. Will definitely make this again.

    1. Hi Savannah – You could omit the banana. I have also added frozen cauliflower and that works well too for an added source of veggies, and you don’t taste them. Enjoy!
