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.

    Cold cereal needs protein to make it filling. I either use a protein shake instead of milk or make a parfait with yogurt. Lately, I’ve been making PB2 milk for my cereal. Now that’s yummy.

  2. Juliet says

    Why have several of the recent recipes you posted just been old recipes? This one, the snack bars, the spaghetti o’s, (there may have been a couple others too) I am pretty much positive I have already seen on the blog…Are they just favorites? 🙂 I hope i don’t sound rude I was just wondering why this is haha. Would love to see more new recipes (the buffalo chili looks great though!). Thanks!

      Katie is going back and updating some of the reader favorite recipes. From her blog:

      Now that I’ve finally started posting videos (what took me so long?!), I’m going back to some of the most popular recipes of three to four years ago to remake them, add videos, and see if I can make the original recipes even healthier.

    • Jason Sanford says

      It will depend greatly on the type of milk you use and whether you add any sweetener. If you don’t add sweetener, it’s just the amount of sugar in a banana.

  3. Laviza says

    It’s Yummy, Learn New Things From Your Blog.I’m Not Good in Cooking But I am tried to learn.You Writing Style is Awsome.Thanks For Sharing with us.Keep it up.

  4. Shirley says

    Hi Katie, is there any other fruit I can sub the banana for? I can’t stand the banana flavor in smoothies
    Thank you!

  5. Julia says

    It sounds absolutely yummy. I really have to try it soon. So far I’ve only had the fruity types of smoothies. But this sounds like a proper satisfying breakfast.

  6. Sherry S. says

    This was so yummy! And I liked it because it wasn’t too thick for me. (I cut the recipe in half for a single serving, but used 1 cup of unsweetened almond milk, plus a tiny splash more) Every day I usually start my day with your “Shamrock Shake” smoothie recipe, but this will make for a really great addition for variety. Thanks, Katie!

    I’d love to try it again with a handful of chocolate chips or a little cacao powder (anti-oxidants, yay!) to see if it will taste like a chocolate peanut butter cup. YUM. 😉

  7. Sherry S. says

    I’ve never used powered peanut butter before but would love to give it a try, so I have a question out of curiosity. Do you just measure out the tablespoons of the powered pb2, or do you have to mix it with a liquid?

    The only reason I ask is because when I checked out a container of pb2 at my grocery store, I noticed it had instructions to mix it with a liquid to make a spread. Since this recipe is for a drink, not going on (for example) a piece of toast, do you bother to mix it with a liquid? Or do you just use the powder itself in the smoothie?

    Thanks, Katie!

    Peanut butter smoothies were a childhood treat of mine. My brother wasn’t a fan of “normal” smoothies, and my sister absolutely DESPISED peanut butter (I enjoyed both on a semi-regular basis), yet they both loved peanut butter banana smoothies. Must have been the chocolate. We used Hershey’s chocolate syrup and never added anything resembling oats, though, so it was most certainly not as healthy as your version, but childhood memories of my little brother waking me up with the annoying sound of a blender made me try this recipe. And it was good.

  9. Lindsay says

    I like combining PB2 and peanut butter–getting the creaminess from a few tbsps PB and additional PB flavor from the PB2. Other optional add-ins I’ve enjoyed: frozen berries for a PB&J shake, 1 tbsp protein powder for added protein, and/or 1/2-3/4 c. frozen spinach or kale to get yer greens.

  10. Sara says

    I made this tonight after seeing it in my feed. I really never make smoothies, but i tried it! So good! I used local honey as the sweetener..

  11. Lula says

    I tried a few of your recipes and they were all very delicious. I am not a big fan of peanut butter or smoothies but I find this one very tasty and filling.

  12. Nyema says

    This Peanut Butter Banana Smoothie recipe is A MUST TRY!! I made it yesterday for lunch and again today for breakfast I’m addicted lol. The added oats is genuis it really makes the Smoothie thick and creamy I usually eat overnight oaks for breakfast but since trying this I am now drinking this for breakfast. I use 1 frozen banana, dash of salt, 2 cap fulls of vanilla extract, 2 spoonfuls of peanut butter, 1 spoonful of honey, handful of ice, a scoop of my protein powder and unsweetened almond milk Ohh and can’t forget the 1/3 of oats which I blend first then add all the remaining ingredients. The finishing result is super delicious, thick and creamy. Thank you for such an great recipe.

  13. Sarah-Beth says

    yeah! Drinking this right now but (obviously) I added cacoa powder. Delicious! Tastes just like a chocolate milkshake!

  14. Girls in London says

    My best friend has perfected this recipe. Take protein powder and replace with a good lashing of Baileys. Amen.

  15. Tiffany says

    Lovely recipe. Perfect consistency for me. We get three smoothies from this recipe and we are ab to accompany them with a fry up!?

  16. Char says

    I’m a nurse, and I love the convenience of a smoothie for breakfast. My stomach isn’t awake enough to have food that early in the morning, but I can suck down a smoothie on the way to work. It gets me through until things calm down in mid morning, and I can have a snack. My method is to have small meals throughout the day instead of trying to sustain my energy until my blood sugar drops too low.
    I like frozen bananas and pb powder and Greek yogurt. I love the addition of oatmeal. Great idea!

  17. Stuart says

    I’m going to try this recipe and include icecream.
    I’m tempted to add a raw egg for more protein and to make the smoothie more filling.
    Can anybody tell me if it is safe to eat raw eggs now?
    Im not pregnant and have no allergies.

  18. Sarah says

    This was delicious, although I didn’t read that it was 2 servings so I totally just downed 718 calories in one sitting! Hahaha whoops! I’m totally fine with that since I’m pregnant and have had hyperemesis and lost 20lbs so far. I’ve been looking for a way to get more protein in since my unborn child decided I needed to be a vegetarian and some days vegan. Pretty much the only animal product I can stomach is milk, anything else from an animal makes me nauseous to even look at.

    Unfortunately the protein shakes I drank before my pregnancy contain some ingredients that can change my hormone balance along with other natural products that haven’t been tested on the affect on an unborn child. As I looked at other protein powders more question came when it came the the amount of heavy metals they contained such as mercury!! Ahhhhh scary stuff…

    I came along this recipe and just tried it out today! The bananas sweetened it just perfectly (no need for additional sweetener for me!)

    I used:

    2 frozen bananas
    1/3 cup rolled oat milk (gluten free organic)
    6 TBS PB2
    1 cup 2% milk
    1 cup fat free milk
    Pinch of salt

    Next time I’ll just cut the recipe on half, although it was great getting in almost 40 grams of protein in one sitting! With having Hyperemesis the past 2.5 mo the I’ve been lucky to get in 20-30 grams of protein ALL day! Now that I’m feeling better I’m searching more plant based protein sources which I think has helped with my nausea and helping me on the road to recovery from HG! This shake will be a life saver for me! Thank you for sharing!

  19. Alene says

    I haven’t read all the comments, so I apologize if someone already wrote this. I have to be gluten free so I have some oat flour in my pantry and I used it instead of oatmeal ground finely. It worked perfectly! I adore peanut butter as well as bananas, so you pushed all my buttons! This was delicious, with 2 medium sized frozen bananas, 3 tablespoons of oat flour, 3 tablespoons of peanut butter, and 1.5 cups of skim milk. I’m in heaven! Thank you!
