    Aside from maybe chocolate, few foods taste better with freshly-roasted, salty peanut butter than a perfectly ripe banana. And aside from maybe pancakes, the best breakfast consists of smoothies. My Peanut Butter Banana Oatmeal Smoothie combines the best of both worlds and is morphed into a well-rounded breakfast thanks to yogurt, milk, and oats.


    • Banana: Naturally sweetens the smoothie and adds a creamy texture.
    • Milk: Use whatever milk you have on hand, any and all will work.
    • Greek yogurt: Greek yogurt is higher in protein than typical yogurt, and adds to the creamy texture of the smooothie.
    • Oats: I use old-fashioned oats, and they make the smoothie more filling while being a great source of fiber, calcium, and iron.
    • Peanut butter: A huge source of protein, while also being creamy, delicious, and nutty.
    • Cinnamon: Sweet and woody in flavor, cinnamon is a great way to get many antioxidants.

    1. Hi!!! This looks amazing but I’m calorie counting and would like to know how many calories for a single smoothie?? Thank you

    2. I tried this smoothie this morning and it was great! I do have a question about the nutritional data. I’m on a special low calorie diet and when I calculated the calorie count I got 560, per serving. The only change I made was using non-fat Greek yogurt. Just curious how you calculated 294. I’m hoping I goofed somewhere because 560 is half my daily calories!

      1. Hi Amanda –
        Oh my goodness, this recipe should have been marked as 4 servings, not two! Please accept my apologies. As a calorie counter myself, I know how important it is to have accurate nutritional information. I do hope you forgive me. Also, I’m so glad to hear you enjoyed the smoothie!!

      2. Hi Amanda,
        Be careful with the special low calorie diets. I bought a fitbit and used that as per the guidelines, I was able to eat any food while keeping under the calorie count for the day. I was also able to eat over 2000 calories on the fitbit diet if I chose to perform more exercising. It is the first diet I went on in my life. I lost the weight in 2013 and kept the weight off because I did not have to change any of the foods I ate.
        If I was required to only eat 1000 calories, I would have had a very difficult time.

    3. This recipe sounds excellent, and especially like something my husband would enjoy. We would add protein powder to it to bring up the protein levels to what we need. Looking forward to making this.

    4. Loved all three Recipes! I think my favorite was the cottage cheese and Avocado one, I had never thought of that combo before… Really yummy. I also love the smoothie I am trying to cut calories a bit more so I would substitute the all natural PB which I Love but can be high in calories with the product PB2 since it gives the same flavor in a smoothie and still adds protein but a few calories less…as always thanks for your great Recipes and tips I love your blog!

    5. Hi, my name’s Gina, and I’m with you, I LOVE my PB!! I can’t get enough, and these photos are making me drooool. Looks amazing. And the overnight oats? I gotta try those (I tried them once and had no luck, but I will try, try again!)
