Peanut Butter Green Smoothie
This post may include affiliate links. Thank you for your support.
The best green smoothie with frozen banana, peanut butter and baby spinach. If you’re new to green smoothies this is the perfect recipe to start with.
If the thought of drinking kale, spinach, collard greens and swiss chard makes you cringe, please don’t leave just yet! I promise that you can create green smoothies that actually taste good and they’ll make you feel good too!
To be honest, I’ve always liked green smoothies, but never tried drinking them on a regular basis until recently.
And it’s been amazing!

I’ve made a a bunch of different green smoothies over the years and I always feel awesome after drinking them.
It makes sense considering leafy greens are one of the most nutritious foods you can eat. (Source) It’s one of the reasons I love incorporating one large salad a day, but putting greens in your smoothie is such an easy way to pack a lot of greens into one meal.

Benefits of Eating Dark Leafy Greens
I’m sure you’ve heard that greens are good for you, but did you know that greens are high in calcium, magnesium, iron, potassium, phosphorous, zinc and vitamins A, C, E and K? They’re also crammed with fiber, folic acid, chlorophyll and many other micronutrients and phytochemicals. The benefits of leafy greens are amazing. Here are a few (read more about them here):
- Blood purification
- Cancer prevention
- Improved circulation
- Strengthened immune system
- Promotion of healthy intestinal flora
- Promotion of subtle, light and flexible energy
- Lifted spirit and elimination of depression
- Improved liver, gall bladder and kidney function
- Cleared congestion, especially in lungs by reducing mucus
Getting Started with Green Smoothies
- Baby spinach has a mild flavor and is a great place to start! Add a handful or two of baby spinach into your smoothies then work your way up to adding a larger amount of spinach or different greens that are a little more pungent like collards and kale.
- Use frozen fruit! Frozen bananas and mango add a nice sweetness, great texture and cover up the taste of the greens really well. <– Just make sure your bananas are ripe and that you peel them before freezing. I like to slice them in half (or in chunks) and put them in freezer-safe bags or storage containers before placing in the freezer.
- I recommend using a high-powered blender like a Vitamix. If you don’t have one you can still make green smoothies, but you’ll probably have to deal with pieces of un-blended greens. Just be sure to check your teeth. 😉 For what it’s worth, I LOVE my Vitamix.
- Remember that green smoothies don’t have to be green. When you include other colorful fruits (like berries) into the smoothie the color isn’t always green.
- I’ve been using plant-based protein powder in my smoothies. My favorite protein powder brand is sweetened with stevia and that definitely helps to make the smoothie taste delicious.

One of my favorite green smoothies to date is this one with banana and peanut butter. This combo never disappoints and it’s delicious in this smoothie! I promise you won’t taste the spinach at all. I hope this post will inspire you to try a green smoothie, if you haven’t before and if you have, perhaps it will be a friendly reminder to add a green smoothie or two back into your routine. Drink up and enjoy all the great benefits!

You have inspired me, Green smoothies here i come!
Love the recipe! When you say 1-2 Tablespoons of PB2, is it mixed with water or just the straight up powder?
Thanks!

1-2 Tablespoons of the powder. 🙂
I love green smoothies too! I know bananas are good for you, but the sugar content worries me.
So I sub in 2 TBS of oatmeal soaked overnight in 1 cup almond milk (or usually 24 hours, I put one in when I take one out), and a bit of ice. It thickens it up very nicely!
You’ve got to experiment some more with these, please! I’ve read about ones with sweet potato that sound awesome! But still “green” with spinich or kale.
I love green smoothies! I make them every morning for breakfast. We do blueberries, spinach, almond milk, flax, protein powder and sometimes greek yogurt.
I had my first green smoothie for breakfast the other day and I was shocked by how long I stayed full! Definitely not “just a smoothie” 🙂 It’s such a convenient way to get more servings of fruit/veggies into your day.
That Green Elvis recipe is like what I have for breakfast every single day, unless one of my roommates is sleeping.. and I don’t want to wake her up with the sound of my vita mix 😉 haha
I love the idea of having one as an afternoon snack. I wish I could take my blender to work!!! haha
I’m not sure if a smoothie would last all day in the fridge, but I make my smoothies at home on my lunch break (around 12:30) and they keep in the fridge until around 3:30 or so. Some hold better than others – I think frozen fruits definitely help. Maybe you could try it one day and see…
I love green smoothies, although i always have the same one: spinach, banana, almond milk. so delicious!
I would much rather have them as an afternoon snack, but I work until 5. Do you have any recommendations for smoothie-drinking at work?
Classy, lady! I love drinking smoothies out of pint glasses, so you’re not alone. They feel extra fancy out of Belgian beer glasses!
I haven’t made a green smoothie in a while because I have been on an Ellwood’s green juice kick, but I definitely need to reincorporate them back into my life. Wish I could whip them up at work as a 3PM snack! Maybe I will pre-make and store them in our office freezer??
I love green smoothies! I have a hard time getting all my veggies in so making a smoothie with a couple handfuls of spinach is a great way for me to boost my leafy greens intake. I like making them with a banana + a bit of peanut butter + almond milk. Delicious!
