My easy Coffee Protein Smoothie recipe combines the rich flavors of peanut butter and banana with iced coffee for a creamy, delicious breakfast treat!
Pair this smoothie with my strawberry protein muffins for an easy grab-and-go breakfast.

Why This Coffee Smoothie Recipe Works
- Classic combo with a twist. Sweet bananas paired with creamy peanut butter is a classic combination that I can’t get enough of. Add iced coffee and a scoop of protein powder, and you’ve got a delicious breakfast drink. Pour it into a to-go mug for an easy breakfast on busy mornings.
- Coffee lover’s dream breakfast. I always thought that nothing would beat my original recipe for a coffee smoothie, until I put peanut butter in it. o.m.g. 😱 Friends, this little addition made a huge difference. The following morning, I added a scoop of chocolate protein powder, too, and things got even better. The next morning, I added a scoop of chocolate protein powder too, and it was even more delicious. The creamy texture and rich coffee flavor make this one I come back to again and again.
- Household favorite. Smoothies are a breakfast favorite around here. Our go-to is the one and only green kale smoothie – SO amazing! – or a bowl of this rainbow protein smoothie. We love tossing a handful of ingredients into the Blendtec, and having breakfast ready in just a few minutes.

The Ingredients
You can make this fantastic Coffee Protein Smoothie with just five simple ingredients! This recipe combines brewed coffee with creamy ingredients to create a smoothie that’s rich, flavorful, and easy to make.
- Almond Milk: You can also use regular milk, coconut milk, soy milk, or another milk of your choice.
- Brewed Coffee: Brew a cup of your favorite coffee and pour it into an ice cube tray to freeze overnight.
- Large Banana: Adds sweetness and helps create a thick, creamy texture.
- Smooth Peanut Butter: Adds a rich, nutty flavor. Almond butter or another nut butter works well, too.
- Chocolate Protein Powder: Adds chocolate flavor. For a different twist, try vanilla or another favorite flavor.

How To Make a Coffee Protein Smoothie
Making coffee smoothies is so, so simple. Just freeze your coffee overnight, and in less than a minute of blending the next day, you’ll enjoy a refreshing smoothie.
- Brew and Freeze. Before going to sleep, start by brewing a cup of coffee. Do not drink it. 🙂 Instead, please pour it into an ice tray and place the tray in your freezer.
- Combine and Blend. 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 the mixture is well combined and thickened.
- Consistency. If the smoothie is too thick for your liking, add a bit more milk, about a couple of tablespoons at a time, and blend until combined. If it’s too thin, add ice cubes and mix until combined.
- Serve. Pour into glasses and serve.
Proper Storage
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 right next to a stack of protein waffles! 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.
any recommendations for a good chocolate protein powder?
Hi!
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. 🙂
Love having one of these for breakfast! Gives me a great boost for the day and keeps me full until lunch.
Love coffee, so this coffee smoothie looks amazing!
So stinking delicious! I want this for breakfast every day!
Love this for breakfast! I have made it the last few days and it’s so good.
oh I am totally doing this!! Love coffee smoothie!!
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 ,
Peel
Enjoy
I love this idea! Thank you for sharing!
