Peanut Butter Banana Green Smoothie

Has summer hit your area yet? It’s been hit or miss here but we did have a lovely hailstorm the other day. And I say that with great sincerity, storms are fun so long as they don’t happen constantly.

The recipe I have for you today (although “recipe” might be kind of a generous term for a smoothie, if I’m honest) is great for those hot days when you want a healthy and filling meal but it’s too hot to make anything. It may not seem like much but I’m always surprised just how full I am at the end. Great for lunch (or dinner, if you’re as lazy as I am) and it is awesome for refueling after a long run.

I’ll admit the green color can be a bit off-putting, but it tastes like a peanut butter banana milkshake. If you’re extra afraid of vegetables, like I was when I first started making this, just add a little bit more peanut butter or yogurt until you can’t taste the green. Maybe even put it in an opaque cup if that helps you come to terms with it.

Cold, creamy, and sweet, it drinks like dessert but is a protein- and vitamin-packed meal replacement perfect for any day, but especially great on hot ones. A few years ago we had an extremely hot summer here in Montana (especially by Alaskan standards) and there were a couple weeks where I had one of these for dinner while I sat in front of the air conditioner pretty much every day after work. Five minutes to make and no heat to add to already scorching 98 degrees inside and out. Perfect.

If you’re looking for a quick, cold, and healthy meal (or very large snack), this is the one you want. Go forth and blend!

Note: I like to blend the spinach and milk first to make sure it is well puréed. If you have a really nice blender and/or are not as averse to larger bits of leaf in your smoothie, you can definitely just blend it all at once instead of in two steps. Also! You can totally buy one of those giant containers of baby spinach (like Costco sells), blend it all up at once with some milk (or water if you prefer), and freeze it in to smoothie-sized portions. I used a muffin tin because that’s what I had on hand, and then I use two frozen portions per smoothie. Works great and there’s no risk of your spinach going bad (although I’ll admit getting them out of the muffin tin was somewhat annoying. In the future I will line it with foil or plastic wrap or something.)

Peanut Butter Banana Green Smoothie

Adapted from Iowa Girl Eats
Makes one ~16oz smoothie


1/2 – 1 cup milk (I use 2% but any milk or plant wannabe will work)
1+ cups baby spinach, to taste1

1 ripe banana (peeled, sliced, and frozen)2
1/4 cup yogurt (I use vanilla honey Greek yogurt)
2 Tbsp peanut butter


  1. Blend spinach and 1/2 cup milk until reasonably smooth (no large pieces).
  2. Add remaining ingredients and blend until completely mixed (this could take a minute or so). If it’s too thick, blend in additional milk 2 tablespoons at a time until desired consistency is reached.
  3. Enjoy immediately with a straw and a sunny day.


1  I use one or two cups depending what fits, but you can add up to around four cups if you’re a big spinach fan. You likely want to use more yogurt and milk if you add much more than two cups of spinach.

I typically slice mine into roughly fourths as they fit into my single-serving blender cup better that way. You can slice yours more or less to suit your needs.
