Peanut Butter Banana Smoothie

This ultra thick and creamy peanut butter banana smoothie recipe tastes like drinking a milkshake… and it’s good for you at the same time! 

A peanut butter banana smoothie for a healthy breakfast

I know some people swear by cold cereal for breakfast. But whenever I eat a bowl of cereal, I always seem to be hungry again less than an hour later.

Does this happen to you as well?

However, I do like the convenience of cold cereal. Sure, it would be nice to eat homemade pancakes or waffles or this Healthy Banana Bread every single day for breakfast, but who has time for that?

Especially on Mondays, I want something that doesn’t take all morning to prepare, can be made with just a few ingredients, and will hold me over until lunch.

Enter this easy banana smoothie recipe.

  1. EmilyLovesRaisins says

    Hey Katie!
    This is kinda random but I just wanted to say that I really love your blog. You’re such a positive influence and your personality really shines through. You’ve helped me when I wasn’t sure what it meant to be healthy. Also, you can take some of the simplest ingredients and turn them into something healthy and (more importantly) delicious! I eagerly check your blog everyday in hopes there will be a new recipe, and when there is I am always SOOO excited to try it out!
    All that randomness aside… I used to eat cereal sometimes but I don’t anymore cause I realized that most commercial brands are pretty processed. I totally agree with you about the convenience part though. It would be pretty awesome if someone could make a cereal that turned into pancakes the second it touched milk, but for now I will just have to either take an extra 15 minutes to cook OR just make something super-simple-yet-delicious like this smoothie!

  2. Allison Galassie says

    I’m the complete opposite! Cereal is usually okay for me, but I’m so hungry after smoothies

    • Ange says

      me too! I think for me it has to do with chewing food – I need to chew to feel like I ate something…
      I love cold cereal for breakfast. I keep boxes above my desk at work and have it as I read my morning emails. One of my favourite parts of the day. I don’t think I could ever give it up!

    • Sarah says

      Same here! I have to make a double serving of smoothie (at least) in order to feel satisfied, and then I usually end up needing a second breakfast, hobbit-style. They’re more of an after-work snack for me.

  3. Jennifer W. says

    I love the PB2 you added to this smoothie. Thank you for the post. I need other alternatives for breakfast because unfortunately I am allergic to eggs. This will be great.

  4. Lisa Ernst says

    Love your blog! This looks like a good alternative to cereal, I can’t wait to try it. Lately I’ve found a good alternative to cold cereal that’s fast and easy. I cook up a large batch of quinoa and refrigerate what I don’t use immediately. Then in the morning I’ll scoop some out in a bowl, cover with unsweetened soymilk, add a few drops of stevia and vanilla extract. It tastes good, is fast, filling and nutritious.

  5. Jules @ WolfItDown says

    This looks delicious, and so filling, I bet it went down a treat 🙂
    Sometimes I eat cold cereal yeh, but I tend to just opt for oat porridge. Saying that, this morning I had a cold-served overnight banana oat jar topped with some granola, and it was great!
    I hope you’ve had a great start to your week Katie, thanks for this recipe 😀 x

  6. Handmade by Lorna says

    I can never usually get on with smoothies – I think that it is the thick texture I am not keen on, but I think that I will give this one a try as I love peanut butter and bananas – could a fresh banana be used?

    • Karen says

      I think that if you use a fresh banana the smoothie won’t be as thick, but since you said you don’t like the thick texture, maybe that would be a good thing.

      • Becky says

        Hi, I made it with fresh aka non frozen bananas and it worked. One will have to add ice to it because the bananas are at room temperature. I like my smoothies thick.

        All around freaking delicious.

        Thank you.

    • Claire says

      You can use a fresh banana, but the smoothie won’t be cold. I I just made this smoothie this morning and it came out pretty thin, just use a smaller banana or more milk to thin it out! 🙂

  7. D says

    Katie, ever since seeing your creations, I have always been making breakfast the night before. I’ve done blended cereal, oatmeal (porridge or baked), oat bran (porridge or baked), interestingly, I don’t seem to find any recipes with baking oat bran. Also, I’ve gotten into bulgur. I never care to have cold cereal anymore.

    I cannot wait for your book to come out in the fall!

  8. nuts4knits says

    Yes! One of my favorite PB2 recipes! You can also add 1-2 Tbsp of Silk Road cocoa powder and 1/2 cup frozen peas (you can’t taste the peas). Yum! I love your ideas.

  9. Marlowe says

    I make this in the afternoon when my the munchies hit. I haven’t added oats, but I do throw in a couple of handfuls of spinach. the PB and banana cover up the flavor and my kids love the green. I will try adding oats today.

  10. Mia (Mia in Germany) says

    Like Allison, I’m fine with either cold or hot cereal, but smoothies only hold for about one hour or so. I love banana milk with pb, will give the addition of oats a try. Maybe it will fill me up for more than one hour!

  11. Jess @ The Baguette Diet says

    I agree 100% on cold cereal–I feel like I could eat 5 bowls and still feel hungry an hour afterwards! I love banana and PB for breakfast, though–usually as part of a yogurt bowl or on an English muffin, but this smoothie sounds like a great idea too!

  12. Avra-Sha Faohla says

    I think it depends on the cereal. I usually have a bowl of bran flakes with a banana, and it keeps me full until lunch! Grape-Nuts are also a good choice to last me until lunch. But I would only eat Cheerios for breakfast as a last resort because when I eat Cheerios, I get hungry again much sooner than that.

  13. Susan says

    Yes, I eat cereal for breakfast, usually about 1-2x per week. My solution to the problem of getting hungry is to add a scoop of protein powder (and a tablespoon of flaxseed), plus have a stick of string cheese – unless I use non-fat milk, in which case the calories prohibit cheese. We also are in the habit of having a morning snack, because of the eating plan we are on, which specifies that to keep our metabolism up, we should eat every 2-3 hours. I know we were probably all raised to believe that one should just eat 3 meals a day, with maybe an afternoon snack, but current nutritional wisdom says that is no longer the best way to go. I’m looking forward to trying this smoothie recipe – smoothies are always a good breakfast.

  14. Red Deception says

    I make something similar to this for the boyfriend – he is wary of the green “healthy” smoothies, so if it’s loaded with PB and banana … he’ll eat it! I like to throw frozen strawberries into mine just to add a bit more sweetness.

  15. Marci says

    Hi Katie,
    I’m writing a book and will be referencing your website in the resources section. I would like to print at least one and possibly more of your recipes in the text of the book. The recipe would of course be accompanied by a notation saying that it is your recipe and repeating your URL. Is this alright with you? Could I say “reprinted with permission?”
    Please let me know.
    Thanks kindly,


    • Kim says

      I made with unsweetened vanilla almond milk, frozen banana, PB2, And just a touch of honey… is was absolutely delicious! So simple, so satisfying!

  16. JC says

    I have actually been in an odd bit of a habit for the past year or so – waking up any number of times between midnight and 6 to snack on… frankly whatever comes to mind. More often than not the munchable of choice is cereal. While I can’t testify for these nights/mornings, one the days where I manage a normal breakfast [with cereal] it isn’t too filling unless it is oatmeal, and even that doesn’t tend to stick for too long.

    Speaking of which, I just started getting into smoothies as an accompaniment to the library/while doing field work. It’s a low-fuss way of keeping full, and this recipe sounds like no exception! I’d be tempted to try bran in lieu of oats however.

  17. Tammela says

    This sounds great. I like the idea of using oats for fiber and thickening. I often eat muesli with almond milk and banana for breakfast, and it usually holds me for 3-4 hours. If I need something more substantial, I’ll make cooked oatmeal and stir in peanut butter in banana (kind of like this smoothie, but in warm form!).

  18. Jessica says

    Cold cereal and milk is a snack. Breakfast and post workout cereal is with greek yogurt. I’m usually a flavored Cheerio’s person, which is still better than my all time favorite Reese’s Puffs but still not enough protein and fiber on its own to keep me satisfied. Mini wheats…different story, but I never go through them fast enough to warrant buying them often.

    • Sadye says

      Yes! It’s my favorite bedtime snack. Got into the habit when I was working second shift, and now it feels weird to eat cereal for breakfast.

  19. Polina says

    I thought it is only my problem – after most of cereals I am quickly become hanger. Though it was one exception: I have done your 5-minute oatmeal and it was really filling! But it won’t stop me from trying this:) Thank you for another one beauty.

  20. Linda says

    This is absolutely crazy since I was planning on going home and making this exact smoothie before you posted the recipe. We think alike:) The smoothie is also fantastic with a tablespoon of cocoa powder because as you know, chocolate makes everything better!

  21. Shonalika says

    Haha, I’ve been making this exact smoothie as a snack quite regularly over the past week… but I haven’t had it for breakfast so far because I need a BIG breakfast. Cold cereal can’t keep me going for more than an hour – especially with the minuscule portion sizes listed on the packet! Adding oats would probably make the smoothie entirely breakfast-worthy, without affecting the flavour – definitely going to try it!

  22. Bethan says

    This looks absolutely delicious. Thank you so much for sharing! Would you recommend this as a post-work out treat? x

  23. Carolyn HSmith says

    No, Katie, I don’t eat cold cereal for breakfast. I love to have it instead of dinner on hot days, and it holds me over til time for bed.
    This recipe sounds like it will be a great prize for a hot afternoon! I have the Pb2 and I like it in recipes. (Tried it in pb and jelly, but it wasn’t the same for my little one, so I had to make him a regular one).
    Til next time, and thanks for loving us thru your wonderful recipes!

  24. Chris says

    Hey Katie, this smoothie looks so good! I like your addition of oats to a classic PB recipe. I still haven’t tried oats in a smoothie. I think some soaked buckwheat would work too. To answer your question, I haven’t had cold cereal for breakfast in several years. I do like cold cereal but I avoid it since its a processed food and I always found myself overeating it because I was never satisfied! I would love to see more lunch and dinner recipes from you! I think I may have left that comment before, but I’m telling you again! 🙂

  25. Bianca says

    I basically had this for breakfast this morning but made with Justin’s Maple Almond Butter and Vega French Vanilla powder….so good!

  26. Tonii Nuttall says

    I’ve been drinking a similar smoothie for breakfast for decades. I’ve never added the oatmeal, and will do that. What I do add is a bit of powdered chocolate – makes it taste like a pb cup!

  27. EVA says

    For two years, I’ve had nothing but Rice Chex and almond milk for breakfast. I feel like a whole different person and am usually in a crabby mood if I DON’T have it! Funny thing is that cereal is pretty much the only thing that keeps me full….that and baked potatoes. Basically carbs in general are the only things that stick with me. Which is fine in my book!
