This kickin’ coffee smoothie swaps the usual milk for brewed coffee. Made with frozen banana, dates, nut butter, oats, and cocoa powder, it tastes like a thick, creamy mocha milkshake and will give you serious energy for your day!

Everyone can be a morning person with this coffee smoothie recipe!

Much to Ben’s demise, I am unbearably chipper in the morning—after my mandatory cup of coffee that is!
This coffee smoothie uses leftover cooled coffee to create a thick, creamy breakfast drink that gives mornings an energy boost.
I like to add a scoop of chocolate protein powder to give the smoothie extra staying power, along with a pinch of cocoa powder to make it extra chocolaty.
It’s a yummy alternative to fruit-based smoothies like this Greek Yogurt Smoothie and Strawberry Smoothie.
Thanks to the additions of nut butter, protein powder, and oats, it’s more filling than my copycat Starbucks Mocha Frappuccino.
Even if you don’t consider yourself a “morning person,” this coffee smoothie drink will put bounce back in your step!

Key Ingredients
Find the full list in the recipe card below, but here are some notes to keep in mind.
- Banana. Use frozen to make the coffee smoothie thick, cold, and creamy. If you don’t have a high-powered blender, use a fresh banana instead, then thicken the smoothie further with ice.
- Coffee. In addition to an energy boost, the coffee gives the smoothie richness and depth. It’s a great way to use up leftover coffee from the day before.
- Oatmeal. Provides additional fiber and thickens the smoothie. Check out this Oatmeal Smoothie too!
- Dates. Instead of sugar, this smoothie is naturally sweetened with dates. I recommend Medjool, which are especially soft and sweet.
- Nut Butter. The healthy fats from the nut butter make this smoothie extra satisfying. I’ve used both almond butter and peanut butter; both are delicious.

Nutrition





I wasn’t sure how I’d feel about oats in a smoothie, but they actually made it more filling and the texture was smooth. I used my high-speed blender as suggested and everything came together quickly. I added a little cinnamon for fun and that worked really well with the coffee and cocoa. Would definitely make it again.
So glad to hear, Scarlette! Thank you!
Tried this for the first time today and it was pretty good! Not too sweet, which I liked, and the coffee flavor came through nicely. I think the banana really helps tie everything together. It feels like a healthy treat without tasting too “green” or bland. Love this! Thank you for sharing.
Great to hear, thank you Bianca!
I made this after my morning walk and it hit the spot. It’s not overly strong on the coffee flavor, but just enough to wake you up. I didn’t expect the banana and coffee to work this well together. I blended it with a few ice cubes to thicken it up and it turned out creamy and smooth. Might throw in some cinnamon next time just to mix it up a bit.
So pleased to hear it Irene, thank you!
I already know it’s gonna be good. Cawfee. Come on!!
But what if I don’t have protein powder?
Hi Jan, you can just leave it out! Enjoy!
This looks amazing. Can a double shot of espresso be substituted for the 1/2 cup of coffee??
Hi Suzanne, I think that could work! Enjoy!
I have not made it yet but anything I can use instead of protein powder?
Txs
Hi! You can leave the protein powder out! Enjoy!
Hi Erin!
I’m wanting to make your coffee smoothie. Can I make it without the protein powder?
Sure! Enjoy Jan!
I haven’t made this yet but I have the ingredients. Erin isn’t there a lot of sugar in this coffee smoothie?
I’ve been warned that I have pre diabetes so I am concerned. Advice?
Hi Jan! The amounts work well for us, but when it comes to health advice I am not qualified to give advice. I would suggest speaking with a registered dietitian or nutritionist to help guide you in your pre-diabetes journey.
Hi Erin, I wanted to let you know how much I appreciate this recipe and your other high protein recipes. My husband recently came home from a 10 day ICU stay, was very weak, and had no appetite. He acted like it was torture to have to eat anything, and would have a few bites at a meal after much prodding. He also hates Ensure. Oh, and he’s vegetarian. Anyway, I made this shake for him one morning and he enthusiastically drank the whole thing! I’m convinced this was the first step towards regaining his strength. Since then, I’ve tried some of your other high protein recipes, and he has devoured every one! I believe that enjoying these foods has re-stimulated his appetite, and he is now doing much better. I can’t thank you enough for being such a good resource for high protein — and tasty — recipes!!
Thank you so much for sharing, Sandy! Hope he is recovering well!
