Just 4 ingredients! No added sugar or artificial ingredients! This Low Calorie Peanut Butter Banana Spinach Smoothie is here to make your New Year’s resolution a breeze.

This low calorie peanut butter banana spinach smoothie recipe is easy and delicious! And the spinach? You won't even know it's there!

Oh heeey, January! How did you get here so fast?

Did some of those Christmas cookies linger a bit too long on the hips? No? Just me? Or perhaps you just like delicious smoothies that pack in healthy spinach and tons of flavor without a million calories? Me too. Looking to do a total reset? Start with this ginger detox drink then move on to healthy smoothies and healthy filling salad recipes!

It looks like the healthy green smoothie that it is but it tastes just like a decadent, calorie rich peanut butter banana milk shake!

The secret is PB2. I found this magical stuff at the grocery store and haven’t looked back. It’s essentially roasted peanuts pressed to remove 85% of the fat! 2 tablespoons has only 45 calories and there are no weird ingredients. Get out!

This flavorful smoothie clocks in at only 235 calories but still has over 13 grams of filling protein. I’ve been fueling up with this smoothie post workout and powering through the rest of the holiday craziness!

Fuel up without filling out. That’s the tagline for this smoothie, because what self-respecting smoothie doesn’t have a tagline? It could also be the tagline of this strawberry banana spinach smoothie, which is equally delicious.

You can further slash the calories by using unsweetened almond milk, but you will also forgo some of that filling protein. Your call!

Ingredients  

  • 1 cup unsweetened soymilk
  • 1 banana frozen, cut in ½ inch pieces
  • 2 tablespoons PB2
  • 1 cup spinach

Instructions 

  • Place all ingredients in a blender, Magic Bullet or Nutribullet. I use a Nutribullet because it processes it finer and it’s already in a cup to go!

Notes

If you don’t have, or can’t find, PB2, you can substitute 2 tablespoons of natural creamy peanut butter but it will add 165 calories and 2 grams of protein.
You can further slash the calories by using unsweetened almond milk, but you will also forgo some of that filling protein.

    1. I hope you tried it, Mira! It’s so beyond easy! And I totally get it – you’re talking to someone who made twice as many cookies as usual! 🙂

  4. I really need this right now. My husband and I spent all day yesterday putting up new field fencing around our pond to keep our geese from escaping (they keep getting into our neighbors winter wheat field). It was well past dark when we finished. Cold, hungry and no time to fix what I had planned we chose a quick trip into town for the closest fast food (Carl’s Jr.) Bad decision. Fast food make me so sick to my stomach. I think that this smoothie will fix me up nicely.

  5. This smoothie looks delicious, mate! And after all of the Christmas desserts (and beers), I can totally see myself sitting down on the couch with a big, green smoothie. I might have to dip a cookie or two into it, though. Is that allowed? 🙂
