This easy Coffee Protein Smoothie recipe combines peanut butter and banana with iced coffee! It’s a super delicious & healthy breakfast treat! 

Pouring coffee smoothie into a to-go cup.


Sweet bananas paired with smooth peanut butter is a classic combo that I can’t get enough of. BUT, pair those two with iced coffee AND a scoop of protein powder, and you’ve got yourself a new favorite breakfast drink. Bring it in a to-go mug to kickstart your day in the best way possible! 

I always thought that NOTHING was going to beat my original recipe for a Coffee Smoothie. NAH.THING. Until… I put peanut butter in it… o.m.g. 😱 Trust me, friends, this little addition made a huge difference. The following morning I also added a scoop of chocolate protein powder, and things got even better. 

Smoothies are a breakfast favorite around here. Our go-to is the one and only Banana, Kiwi, and Kale Smoothie – SO amazing! – or, a bowl of this Rainbow Protein Smoothie. We all got used to just throwing a bunch of good-for-you ingredients in the Blendtec and, with just a whirl, our breakfast is done.

Protein Smoothie in a cup

Just like the ones mentioned above, this Coffee Protein Smoothie is a packed powerhouse of antioxidants, vitamins, and fiber, but best of all is the delicious coffee flavor! Coffee lovers, we’re about to celebrate! 


  • brewed coffee, frozen
  • banana
  • smooth peanut butter
  • chocolate protein powder
  • almond milk (you can also use regular milk)

Iced coffee, banana, and peanut butter in a blender.


  • Start by brewing a cup of coffee before going to sleep. DO NOT drink it. 🙂 Instead, please pour it into an ice tray and place the tray in your freezer.
  • The following morning, pour out the coffee ice cubes into a blender.
  • Add a banana to the blender, as well as the peanut butter, protein powder, and milk.
  • Blend until mixture is well combined and thickened. 
  • If it’s too thick, add a bit more milk, about couple tablespoons at a time, and blend until combined.
  • If it’s too thin, add a couple of ice cubes and blend until combined.
  • Pour into glasses and serve. 


Smoothies are the perfect meal prep – they keep in the fridge for up to 3 days – and are an easy way to keep our first meal of the day on track.

  • Store smoothies in an airtight glass container secured with a lid. Refrigerate for 2 to 3 days. 
  • Smoothies can also be frozen into popsicle molds – they are perfect on a hot summer day.

    I peel bananas and slice them into large pieces. Put them in a ziplock freezer bag and keep in the freezer. I cut up four or five at a time, because they do go bad quickly. To me this is easier than freezing the coffee. (I do refrigerate the coffee overnight.) Vanilla protein powder is also good. Great way to start the day!

    Hi Katerina,

    Coffee in smoothies! Yum! I was dreaming of it and then I found your recipe. I will make it for breakfast tomorrow. Thanks! I often use my home made non diary milks for smoothies. Hemp milk is one of my favourites as it’s so easy to make and creamy.

      I almost always use “Perfect Keto Chocolate Protein Powder” or “FitMiss Delight Protein Powder”. I like Perfect Keto protein powder because it’s also a prebiotic with mct oil AND collagen protein… all in one. :-)) FitMiss Delight chocolate protein powder is also something I have on hand and I like that one because it tastes really good. 🙂

    I love adding banana and peanut butter to my Click Active Coffee Protein drink. It’s got two shots of espresso and mixes easily in water so I don’t get extra calories from milk. I’ll have to try adding a scoop of chocolate! Thank you!

    For me , freezing bananas as they over ripen is easier then freezing my
    Cold brew coffee . You can freeze them up n their peels and then run them under hot water or stick them in the microwave or leave them on the counter for five minutes ,
