Have you ever been in the mood for a coffee protein shake recipe? Like you wake up, and you just want your coffee, but may not have an appetite, but you know you need nutrients?

Well, THIS protein coffee recipe is for you. 

I love it for summer mornings. It’s nice knowing that a coffee and protein shake together can be filling, satiating, satisfying AND give me the caffeine I need with two small kiddos. 

If you’ve been reading my blog for a while, you know I love my coffee. Plus, coffee before running can be advantageous for performance!

I’m from Rhode Island. Rhode Island, and the Northeast in general, is Dunkin’ Donuts mecca. We drink iced coffees all year round (yes, even in the winter).

I think people think I’m pretty crazy when I order an iced coffee in the winter. I’ll have an occasional hot coffee then. But, in the summer, all I crave is iced coffee. Cold brew, iced americano, iced latte – you name it. If there’s ice (and coffee/caffeine in it), I’ll drink it!

And with this peanut butter coffee banana smoothie, I quench my iced coffee needs, while also hydrating with other nutritious ingredients, too!

…Think peanut butter, chocolate, banana and coffee all in one.

Can You Put Coffee In A Smoothie?

Of course you can! There’s coffee milk, coffee ice cream, so why not a coffee flavored smoothie?

This is my favorite method for adding coffee to a smoothie because there are other flavors mixed in, too. 

What You Need For This Coffee Banana Peanut Butter Smoothie

Make sure you have:

  • choice of coffee (brewed, iced, cold brew)
  • banana
  • greek yogurt
  • milk
  • peanut butter
  • peanut butter powder (I love this one)
  • cocoa powder
  • vanilla
  • oats

If you’re someone who loves toppings on your coffee banana smoothie like I do, I suggest trying chia seeds, hemp seeds, granola, fruit, or even an extra dollop of peanut butter!

My favorite granola choices are this pumpkin seed granola or coconut cinnamon maple granola!

How To Make The Best Peanut Butter Coffee Smoothie

Making this protein coffee recipe is as easy as can be!

First, let your coffee cool. Then, all you’ll do is mix the ingredients together in a high speed blender.

I think it’s pretty genius to make a protein drink with coffee. Better yet, serve it as a cold coffee smoothie recipe. This coffee banana peanut butter smoothie recipe is also great for after a morning workout!

Refuel with this carbohydrate protein powerhouse, and get your caffeine while you’re at it too! That’s why I think a coffee banana protein smoothie is genius. 

I will say, it is a bit on the bolder side, so if you like your coffee sweeter, you could use the whole banana, add more sweetener, more peanut butter, more milk or even substitute the milk for creamer. 

This coffee banana peanut butter smoothie can be customized in so many ways. It was my go to post run drink to help fuel breastfeeding

Do I Have to Add Yogurt?

No, you most certainly do not!

I absolutely LOVE the addition of yogurt here. Firstly, it adds the protein we’re looking for (26 grams of protein in this coffee protein shake!). But, it also adds creaminess. And not to mention, probiotics, calcium, potassium and more. 

But, if you’re someone who doesn’t love a coffee yogurt smoothie, you can leave the yogurt out. You could instead add more nut butter, avocado (also adds creaminess), or just add more ice.

Can I Make Other Modifications To This Coffee Yogurt Smoothie?

You can certainly change things up in this coffee and banana smoothie recipe. 

For example, want more of a chocolate flavor? You can add more cocoa powder to make it taste like more of a chocolate coffee smoothie. Chocolate protein powder in place of the peanut butter powder would also help add more of a chocolate flavor! 

If you prefer almond butter, make an almond butter coffee smoothie!

Can I Make a Cold Brew Smoothie?

Yes! In place of the instant or brewed coffee, just substitute your cold brew coffee to make a cold brew smoothie. You can still add the rest of the coffee banana smoothie ingredients accordingly. 

Cold brew smoothies may be more bold, so adjust the other ingredients accordingly!

  1. Oh wow. peanut butter in a coffee drink sounds really good. We don’t have Publix here, but if I’m ever over there and I have an opportunity to go I should go. It sounds like a wonderful experience.

  2. I live in Massachussetts (one mile from Heartbreak Hill!). What is this Publix you refer to? 🙂 Just kidding I have seen them when travelling down south. What powdered peanut butter do you use?

    I’m a new reader and have caught up on some of your earlier posts. Great blog! I look forward to reading and learning more.

    1. I know – I grew up in RI and we did not have Publix!! Such a shame. I use PB2 for powdered peanut butter – they also have a delicious chocolate flavored one – my favorite! Thanks for commenting, Amanda 🙂

  3. WOW! This is all of my favorite things in one smoothie! I did not know you were from the Northeast too 🙂 I hope to one day live down south myself–I’m pretty done with these stupid winters! Anyway–this looks delicious! I love iced coffee in the summer and make my own but also enjoy treating myself every now and again from a coffee shop!
