The Best Banana Oatmeal Smoothie!

Even though I share a lot of dessert recipes, and most are brimming with calories, I do try to eat healthy, and watch my weight. Sometimes I watch it go up and sometimes I watch it go down! Anyway, to keep things in check, I like to drink a healthy smoothie every day, either for breakfast or lunch. This banana oatmeal smoothie is my absolute favorite, and is so easy to make.

There are two things about making smoothies that everyone should consider before turning on that blender. First, it simply has to taste good. There is nothing worse than trying to choke down a smoothie that tastes horrible. Second, it definitely should be nutritious…and this doesn’t necessarily mean that it needs to be low calorie. Many, many healthy smoothie additions are super healthy, but they come with calories as well.

So if you are trying to lose weight, there are three things to consider: taste, nutrition, and calories. If you aren’t trying to lose weight, consider these two things: taste and nutrition.

I had been making this banana oatmeal smoothie recipe for a few weeks, and loving it, when I decided to try it with frozen bananas. Oh my gosh. The frozen bananas took it from really good to absolutely amazing. They make the smoothie thicker, and there is no need to use the ice cubes.

How to Freeze Bananas:

  • Remove the peel from 4 or 5 bananas.
  • Cut your bananas into thirds.
  • Lay them out, not touching, in a 9 x 13 pan or on a cookie sheet.
  • Place them in the freezer for 24 hours.
  • Once frozen as separate pieces, bananas can be stored in a resealable bag in the freezer.

The almond milk I use for this banana oatmeal smoothie recipe is Silk Unsweetened with 30 calories per cup. Even though I’m not a fan of almond milk to drink or on my cereal, I love it in this banana oatmeal smoothie. This is the perfect smoothie for weight loss, but if you aren’t using it that way, feel free to use whatever kind of milk you like best. You can use any kind of oatmeal…instant or regular rolled oats. It’s important to blend the smoothie for at least a minute in order to nicely grind up the oatmeal.

In the printable recipe, I listed optional ingredients. All the ingredients are featured in the video, but only add what you like. I love adding honey and cinnamon, but unfortunately the honey adds quite a few calories, and four Weight Watcher points. (Unbelievable!) Again, if you aren’t using this breakfast smoothie for weight loss, I definitely recommend adding the extra ingredients.

Bonus Tips

  • When using frozen fruit, order matters. After many tries, I found that adding the liquid first, followed by the frozen fruit works the best for blending. The remaining ingredients can be added in any order.
  • Your blender makes a difference. Any kind of blender will work, but one with extra power will mince up the oatmeal better.

Even though I’m not a smoothie expert, I know what I like…and I can honestly say that this is one of the best smoothie recipes I have ever made. It’s fun to add different ingredients, and switch up the fruits. One thing I never change is the oatmeal ingredient.

    anyone that did the almond milk,banana,vanilla extract ,oatmeal smoothie to lose weight did it work did you lose weight

  2. Does the almond milk actually do anything or can I just use lactose free milk? Can you even taste the almond milk? I’m lactose intolerant and not a big fan of almond milk.

    1. Ann Drake says:

      Hi Riley…yes, you can use any kind of milk you want. The reason I use almond milk is because it’s less calories. I have made this smoothie several times with 1% milk when I was out of almond milk and it’s very good. A little bit thicker, but still tasty.

    Very tasty
    Need weight loss recipes for breakfast

  4. Lawanda simms says:

    It was very delicious i fast from Sunday 5 pm til Thursday 5pm and this is my meal replacement

  5. 5 stars
    I am so happy to have found this recipe, which I have made countless times. I also add a scoop of plain Greek yogurt and another fruit…pineapple, mango, strawberries, etc., and sometimes a small scoop of ice cream! Thanks so much!

  6. Kim Ramos says:

    Do you use old fashioned oats or quick cooking oats? If you answered this somewhere please forgive me. I must have overlooked it. Thanks!

    1. Ann Drake says:

      Hi Kim! No problem…I’m happy to answer. I use old fashioned oats. I added it to the recipe card. Thanks!

  7. 5 stars
    This was fantastic. I added 1/2 scoop collagen powder and 3/4 T of my honey turmeric bomb for the sweetener. Delicious!

  8. This sounds so good. I love the idea of adding peanut butter. Pinning this!

  9. 5 stars
    I made it for my family and they loved it- I can’t drink myself due to an allergy to bananas. I also can’t use almond milk because I am sensitive to oxalic acid. For myself, I tried using frozen berries and hazelnut milk.

  10. Thank you for sharing all of these smoothie recipes. I appreciate the variety and additional comments. I like the simplicity of ingredients which also keeps calories down. I usually stick to blueberries and yogurt base. I like addition of oatmeal and almond milk. Also thinking to try peaches since they are in season now. Thank you!

  11. I too freeze bananas for a similar smoothie I make for my husband and I. (We add frozen kale to ours and water instead of the milk.) I have found that you can put the bananas immediately in a zip lock bag without having to freeze them first on the cookie sheet. If the bananas stick together, a quick bang on the counter top will break them apart. It works for us and will save one step. Or alternatively, you could put lay them flat in the zip lock bag not touching each other for the first few hours of freezing and that should keep them apart too. Like Ann, I usually break them up first (I do halves). The most important thing I’ve learned about freezing bananas is (like Ann says) take the peel off. The peel is very hard to get off once the banana is frozen.

    1. I am not feeling well. Chills and fever. I’m hungry but nothing makes me feel like eating except for this banana smoothie. It’s easy to digest and satisfying. Thank you for this recipe.

  12. 5 stars
    I really liked this smoothie! I didn’t add any sweetener, but the next time I make it I will add a soaked Medjool date!

  13. 5 stars
    I loved the smoothie. I was wondering how many times can I drink it during the day?

    1. Ann Drake says:

      Hi Omar…I’m not a nutritionist, but I think you could drink it twice a day. As long as you don’t have a reaction to too much potassium due to the bananas.

    2. Terry Nugent says:

      Tasty smoothie. I did put in a T of almond butter, and the second time I made it, I couldn’t come up with a good reason not to add a handful of spinach. More nutrition, doesn’t add calories, doesn’t alter the taste. Win-win. Thanks for the recipe 😘

  14. 5 stars
    Really yummy, simple to make, and refreshing! Thank you for the recipe!

    Love this and that it has a base of healthy ingredients. My blender gave out and I haven’t replaced it, so I made it in the food processor the first time. The oats didn’t completely break down. This morning, I made it again, using a spare coffee grinder to grind the oats and then used the immersion blender to blend everything together. That worked nicely for me while in a blender less phase!

    I’m not necessarily trying to lose weight but I have a lot of “water weight” and baby fat still. I’m 14 and I have been changing my eating habits. I’m hoping this helps my ongoing hunger throughout the day. I also love this smoothie! It tastes so good and doesn’t have much sweetness. I did add some of Smuckers Natural Peanut Butter to give it a little bit more of a flavor.

  17. Claire kidd says:

    I am trying to lose weight. I am really struggling with snacking at night. So I am going to try this smoothie. It sounds tasty but also good for my weight lose. I will let you know how it goes.

  18. 5 stars
    I thoroughly enjoyed this.

  19. I just tried the banana smoothie and it’s the bomb. I pulsed old fashion oats before adding other ingredients then added banana, almond milk and I was out of vanilla so substituted almond. I feel as if I’ve had a real treat. I’m diabetic so this is great though I could hardly believe 45 gm carb. But it’s better than a cookie, or dish of icecream and I’m satisfied. Another winner, Ann.

  20. Hello my name is daneara and I’ll be doing this smoothie for Weightloss,,,,,I will love to give your banana smoothie a try I’ll be drinking it for breakfast and lunch and 1 hot clean meal like chicken breast and 2 cups of broccoli for dinner with going to my gym 4 times a day,,,,,along with lots of water

  21. Hello from France. This recipe is quick and easy, filling and delicious. I am trying to loose some lbs before Christmas. Let’s hope this lovely banana smoothie helps..
    p.s. My 1st try; I made double quantity (for two people) I had to use an apple to replace a second banana as only had one.. I had all the other ingredients in the house so was a good start to the ‘Smoothie’ trend. Did not use all the other things from 2nd list. But I might buy some good quality protein powder to add in. Do you have any other Smoothies which are around 250 Calories?

    A tres abientot and thanks for your recipe.

  22. I meant ‘posts’. I love them all.

  23. I will definitely try your smoothie! I enjoy all your recipes. I faithfully make the cranberry citrus loaf every Christmas. My husband thinks it’s the best! Thank you for your wonderful post! Have a great week!

  24. Hello! I’m interested I trying your banana oatmeal smoothie, but I have a question. Do u use uncooked oatmeal

    1. Ann Drake says:

      I’m sorry to be so late in answering this…I missed it! No…the oatmeal is uncooked. Enjoy!

  25. Very good, I shared 1/2 with my cross fitter son, he asked for another. Even tho we didn’t have quite a whole bananna he still loved it. I used all ingredients minus the protein powder. Took a screen shot for my smooth file.

  26. Excited to see if this smoothie helps me loose weight. Started going to the gym going on my second month now but it’s so hard to loose all the weight you gain. It’s so easy to gain but hard to loose it.. yesterday I tried the banana and oatmeal smoothie for the first time and loved it. Can’t wait to see if this really does work.But being “PATIENT” to see results is the hardest but can’t give up.

    1. Ann Drake says:

      Hi Jessy! Hang in there and good luck with the weight loss!

  27. Ms sherry burberry says:

    Ok so this is a weight loss smoothie. WOW! Ill say. It taste just like a real milkshake with real ice cream. Like the ones u can get at baskin robins. So so Delicious.

  28. I have to say, this is my absolute favorite diet smoothie above all. Most other smoothies just about make me gag BC of the taste and what not but this one was quite pleasant. I added all ingredients including the optional ones and the flavor at the end was great. Highly recommend :)

  29. Ray wilson says:

    Sounds good will have to try

  30. Wondering about sugar count with banana in this smoothie. Trying to cut cholesterol.

    1. Ann Drake says:

      Hi Susan…I’m sorry but I’m not sure about the sugar count. Bananas are different sizes so I would hate to guess.

  31. Just tried this and it is sooo good!! Thanks for sharing!!!

  32. I made this and it was so good! Though I didn’t use oatmeal as I can’t eat it but instead I used 1/4 cup of sliced toasted almonds and it’s amazing!

    1. Ann Drake says:

      Oh my…almonds are a great idea. Thank you!

    1. Ann Drake says:

      Hi Cindy…I usually use the basic old fashioned oatmeal but instant would work too.

  33. I will try the cleanse, Ann. I will let you know how it goes!!! :)
    Thank you!


  34. Thank you so very much, Ann!!! The girls at WW will be thrilled in the morning to receive this!!! I will try it w/o the PB!!! but I sure do like it with!!!

    Have a great week-end and again, Thank you bunches!!!
    Pink Hugs,

  35. I absolutely love the oatmeal banana smoothie. The drink really fills me up. Thank you for sharing.


  36. Elizabeth Ann says:

    Dear Ann

    Love this post. I want to try this yummy smoothie. May I ask you if the oats are uncooked before I try this smoothie? Can’t wait to try this!

    1. Ann Drake says:

      Hi Elizabeth! Yes the oats are uncooked. I will add that to the recipe. Thank you!

  37. Jan Kinman says:

    Good Morning Ann,
    Just tried your smoothie. Yummy! I used my Ninja single serve container. Of course the banana wasn’t frozen (which I will do for tomorrow for a thicker smoothie). This will be for weight loss so I used the 1/2 scoop of Organic Protein.
    Thank you for sharing your recipe.

    1. Ann Drake says:

      You will love it with frozen bananas…good luck with your weight loss!

  38. this looks delicious. do you use quick oats for the banana smoothie?

    1. Ann Drake says:

      I have used both quick and regular uncooked oats. It doesn’t matter as far as I can tell!

  39. Good morning, Ann Could I ask a favor of you? I love how you share recipes, etc. but could I ask – please – for you to use a bold black or navy print as the grey is very light and makes it rather hard to see. especially those of us with vision problems. Thanks, Ann.
    Have an awesome day!!

  40. To make my smoothies more satisfying and add enough protein, I use half a cup unsweetened almond milk and half a cup of plain Greek yogurt.
