Luscious and sweet, this Peanut Butter, Banana, and Spinach Smoothie will make eating at least one of your daily servings of leafy greens a pure delight.

Peanut Butter Banana Smoothie
We all know that eating leafy greens is important. The health benefits of a diet rich in spinach, kale, arugula, lettuce, cabbage, etc. are well documented.
But, sometimes, even this girl gets tired of salad. I know, I know! (It’s rare.)
For that reason, I’m a huge fan of green smoothies and I make them more frequently than any other kind. But I think we’ve all tasted a “healthy” smoothie that was more gag than it was green.
That is why this Spinach Banana Peanut Butter Smoothie is such a treat. With your eyes closed, you would never guess this is a green smoothie. It was thick, creamy, and absolutely delicious–no bitterness at all.
My kids already want me to make this again. If that isn’t proof that bananas and peanut butter are exceptional for disguising the taste of spinach in a smoothie, I don’t know what is.

Banana Spinach Smoothie
Bananas and Spinach make it into most of my smoothies. But, one of the things that I love about these drinks is that they are so endlessly adaptable.
You can usually add whatever fruit you have on hand to a handful of spinach leaves, splash in the milk, and you’ll end up with a tasty blended treat.

This will sound bad but that looks like the exact same color as Kermit the Frog. I agree with you, if I'm looking at that, my first thought is not "peanut butter" or "banana" because of the color.
I love that color–but love that has all that nutrition from spinach in it.
I adore peanut butter and banana smoothies. I think that adding some spinach would be a great idea. Thank you for sharing with me!
Yum! Smoothies with peanut butter are hard to beat! Never tried it with spinach,but I think I will now! : )
Just made this, but I made only a single serving, used 1/2 cup soy milk, 1 cup spinach, 1 frozen banana, and 1 TBSP of all natural PB. Just the perfect size for me and since I used light soy milk, the total calorie count comes to roughly 230 calories!
I'm wondering if this stays good in the fridge for a day?
I was a little skeptical to try this BUT this is officially the BEST GREEN SMOOTHIE I HAVE EVER HAD! It tastes just like a peanut butter smoothie! It’s simple & delicious. Thank you! This is my new go-to smoothie recipe. Highly recommend! 🙂

I was seeking for a recipe that uses bananas and spinach. I made it today and its wonderful! My only flaw was I didn’t freeze the bananas, but I added ice which made it a little on the thicker side. Overall, fantastic! Thank you!

Delicious. I taste banana and peanut butter but not the spinach. So good!!!
I’m glad you like it, Jeannine!
This was pretty good. Can’t believe this was posted had 8 years ago.
I made a warm version of this since it was winter here, added soy milk and honey for sweetening. Yum.
I’m so glad that you like it, Mel. I’ve never thought to warm it.
This tastes amazing , if you want spinach without the taste this is perfect.
I’m so glad that you’re enjoying the smoothie, Lishy!
