Best Coffee Protein Shake 

I haven’t always been a smoothie girl. If you talk to the other ladies on Team Fit Foodie, they would tell you that I love to start the day off with a piece of arugula toast or a breakfast salad with a hard-boiled egg.

However, protein shakes that are not only flavor-packed, but nutrition-packed like this coffee protein shake are my jam.

Why make this protein shake?

High protein: this protein shake recipe gets you 13g protein per serving!

Favorite flavors: if you are skeptical about coffee + peanut butter + banana, don’t be! You’re going to have to trust us on this one that these flavors are so good.

Easy to make: pop everything into a blender and you’re ready to rock!

Ingredients for Coffee Protein Shake

This coffee protein smoothie recipe is made with 4 ingredient categories. Let’s break it down:

  1. Frozen fruit
  2. Liquid
  3. Protein

Frozen Fruit

We are huge fans of fruit smoothies, meaning that we don’t like to use ice! Insert – frozen bananas!

Bananas truly are the perfect base for any smoothie. And? They are affordable! Check out our post on how to freeze bananas so you always have them on hand for a quick smoothie ingredient option.

No bananas? No problem. Any frozen fruit will work for this recipe! Yes, the flavor will change, but if you add peanut butter and protein powder to any smoothie recipe you are bound to have one delicious smoothie.


The liquid in this smoothie is a combination of almond milk and coffee. You can make your own almond milk or buy your favorite brand at the store. You can even swap it our for oat milk or cow’s milk.

For the coffee, we’re recommending a cold-brew coffee concentrate because it is intense in flavor and you don’t need a lot. However, you can also use chilled drip coffee or even chilled French press coffee. Just make sure that you brew it strong.

Cold-brew brand recommendations

There are so many store-bought cold-brew brands out there these days, but we thought we’d share our 3 favs! Remember, you’re looking for a concentrate, which is much stronger than diluted cold-brew.

Not only do you get a huge boost of protein from protein powder in this smoothie, but also from peanut butter! Peanut butter is super high in protein and healthy fats and it really makes the flavor out of this world. Feel free to use any kind.

As for the protein powder- everybody has their opinion on protein powder. You can use either chocolate protein powder (for more of a mocha flavor) or vanilla protein powder.

Any protein powder will work for this smoothie. You do you and use your favorite protein in this healthy breakfast smoothie! We support you completely.

This was really good. I will be making this recipe when I make my cold brew (magic coffee recipe) so good. I used cocoa powder. No protein at the moment of craving this. Lol. Also chunky pb. It was perfect. Thank you. I will be sharing it.

Fantastic!! Loved the idea of cold brew- something I’ve never considered in a smoothie! Used a couple of cubes of ice only because my banana wasn’t frozen. Loved it!! Wish i would have taken a photo! Thanks.

Fantastic! Hubby and I love smoothies! We currently use a mocha syrup to add flavor, so was smoking for a way to cut it out. Thought cold brew would be great! I googled cold brew protein shake and stumbled upon this! We added more ice ! Also great with oat milk as well as almond !

One quick question I forgot: I am Celiac and Lactose Intolerant. I can work “around” that on my own but am curious if you have a suggestion for a great dairy free (gluten and soy free also) protein powder. Thanks:).
