Hi there! My name is Chantal, and I’m the owner of this site, Ironwild Fitness. I’m also a mom of two, personal trainer, and I’m on my own fitness journey. (Always!)

I know that some of you don’t like backstories, helpful tips and pointers, and a lot of “talk,” when it comes to recipes. But I do! 

That’s because with each recipe I share, there is a backstory – and there are often multiple variations you could opt for. Plus, since I’ve made each of the recipes I share multiple times, I know what little tweaks make them that much better. 

So. If you’re here just for the steps and ingredients – scroll on down. I won’t be offended. 🙂

Go ahead!

But if you want the whole spiel, let’s dive in.

How I Got This Peanut Butter Banana Protein Shake Recipe

Back before I became a personal trainer, I was an overweight mom looking to make healthy changes. I went through some pretty bad postpartum depression and got really unhealthy in my first couple of years as a mom. 

When my daughter was about two years old, I decided to hire my own personal trainer and get back into the gym. 

Honestly, part of that was just that I wanted to be more accountable for exercise, but I also wanted to learn about how to exercise in general.

That’s because I used to be one of those people who showed up to the gym just to run on the treadmill.

I felt that if I could spend a few months working with a trainer, I would be better equipped to work out on my own later. (I was right!)

It was during this time that I decided to become a personal trainer, but that’s another story. 

I was finally going back to the gym again, and I was learning a lot. But I was also plateauing.

That is, I was stuck at a certain weight.

I knew that it was time to dial in on nutrition, but I wasn’t exactly sure where to start. 

Luckily, my trainer was also a mom, and I connected with her and trusted her.

So, I took a leap of faith and bought the top-quality protein powder and meal replacement she recommended. (The stuff is called EQ Complete Meal Shake, and it’s the best stuff I’ve ever had.)

It ended up being the best meal replacement and protein powder I’ve ever had!

I started drinking it for breakfast, after my workouts, and any time I was hungry but didn’t really want to over-do it. 

(Seriously, Q Sciences has the creamiest, least-chalky consistency, plus it’s super high quality. I have their protein powder, preworkout supplement, and the meal replacement you see here.)

But after awhile, I knew I was going to need to switch it up or I would get sick of my plain milk-or-water shakes. 

So, I went back to my trainer and asked her what she normally did with hers.

That’s when she gave me this peanut butter banana protein shake recipe!

I don’t love bananas, but I do love them when combined with peanut butter. And I still love this recipe, even after nearly six years.

And folks, I don’t recommend a lot of things.

But I will always recommend Q Sciences because it’s so much easier going down than any other supplements I’ve tried. Trust me. 

So there’s the bulk of the backstory.

Let’s get to my tips – because you better believe that I’ve tested this recipe many different times.

Tips For The Best Peanut Butter Banana Protein Shake

I have made this exactly the way my trainer said she does, and a handful of other ways.

What I love the most about shakes and smoothies is that you can omit or tweak things as much as you want – and they still typically turn out great. 

You can also just switch out ingredients to suit your dietary preferences or needs. For example, I have made this exact recipe with almond milk and almond butter (both unsweetened) and it’s totally delicious. 

I’ve also made this recipe with whole milk, skim milk, and fat-free milk. Still creamy, no matter what!

There’s also a huge variation in what kind of nut butter you can use – creamy, no added sugar, crunchy, natural, etc. Whatever route you go, you can still get that classic peanut butter banana flavor. 

But my absolute favorite thing about this recipe, made specifically with Q Meal Shake, is that it’s soooo creamy that you can’t even taste the spinach.

Adding the spinach makes it even healthier (leafy greens are so good for you!) than just any old peanut butter banana shake. It’s not chalky at all if you have a high-quality protein powder or meal replacement powder. 

And if you don’t like spinach, you can add baby kale for a similar effect. (Baby kale is typically milder than mature kale, so I always recommend it for smoothies or people who are trying to “sneak” veggies in.)

Anyway, my top tips are that you should experiment with this recipe – and that I recommend using mostly frozen ingredients.

I’ve used regular ripe bananas before, but frozen bananas make things colder and creamier. Otherwise, it’s a super simple, no-fail recipe! I hope you enjoy it!
