Thanks to Oster for sponsoring today’s On-the-Go Healthy Coffee Smoothies! 

Healthy Coffee Smoothies are the perfect way to get your caffeine fix with a side of protein, potassium, and sweetness. We combine concentrated cold brew coffee with sweet bananas, honey, vanilla, nut butter, and just enough oat milk to make this drinkable breakfast ultra smooth.

Healthy Coffee Smoothies

When every appliance under the sun is packed up in a box, including your beloved coffee maker and blender, you grab a Oster Blend Active Portable Blender, concentrated cold brew, and your favorite add-ins to blend up our Healthy Coffee Smoothie. 

These little on-the-go smoothies have been saving my sleep-deprived booty the last few days by giving me a boost of energy with a little hit of caffeine, a punch of protein from cashew butter, and a kiss of sweetness thanks to frozen bananas, honey, and a little bit of vanilla. 

These are sweet, but not cloyingly so (all from natural forms of sugar I might add), and has a solid coffee taste, which can sometimes get lost in other blended coffee drinks. Basically, they’re what I want for breakfast, to snacks, to afternoon pick-me-ups. 

The on-the-go component of this healthy coffee smoothie really came in handy when the movers we hired took over every square inch of our house, forcing me to blend it up in the backyard. The title on-the-go, has never been more accurate. 

Also, this is MY personal inclination when it comes to smoothies, but yours may be different, so add what you love. If you like a stronger coffee, add more or use espresso instead of brewed coffee. Throw in hints of almond extract or use coconut milk instead of oat. We’ve listed a bunch of different options below, so if you’re at a loss, be sure to check those out. 


Coffee. I always keep concentrated cold brew on hand, but you could also use a homemade strong brewed coffee. Cold brew espresso works as well, but keep it mind it’s more potent so you may not need as much. 

Banana. To keep the drink super cold, I like to use a frozen banana. Not only does it add a natural sweetness to the coffee smoothie, but it has lots of potassium too. 

Nut butter. Any nut butter will work great here. In this particular instance I used cashew butter but almond butter was the runner up choice. 

Honey. Honey is almost always my preferred natural sweetener, but you could also use brown sugar or maple syrup. 

Vanilla. Make sure to use pure vanilla extract. And remember, a little goes a long way. 

Avocado. Adding a sliver of avocado adds a really nice rich, creamy texture to the coffee smoothie, as well as plenty of good healthy fat. 

Optional ingredients. For extra calcium, potassium and folate, I love to add in a handful of baby spinach. It may alter the look of the coffee smoothie a little bit, but the taste will stay the same. Also, if you need to sweeten the drink up even more, adding one dried date will do the trick. 

Oster Portable Blender

These On-the-Go Healthy Coffee Smoothies all came about because of a need to throw something quick together despite the lack of a coffee maker or a blender. And our Oster Blend Active Portable Blender is here to save the day. 

This little gadget is a life saver, simply add your ingredients to the 10 oz cup (don’t exceed the max fill line), put the blender top on, turn it on with the press of a button and let it work its magic. Once it’s blended, swap the blender out with the portable drinking lid​ and get on your way. 

It’s also a great to bring on vacations or to work so you can blend up smoothies and such without having to haul around a high-powered blender. Also super convenient, the battery is charged through a USB port, so if you’ve got a phone charger, you’re good to go. 

If you’re interested in picking one up for yourself, you can easily snatch one at your local Target. 

Let’s make Healthy Coffee Smoothies

Prep ingredients. I like to get all my ingredients out first and if I’m taking them with me, portion them out so they can be easily transported. 

Add the ingredients. The key to an efficient blend is to add all the denser ingredients first. So this means first we layer in the ice, followed by the frozen banana, next, the avocado, then spinach (if using), followed by the nut butter, and milk.

I like to add the honey last to make sure it doesn’t stick to the bottom. 

If you’re adding dates, you’ll want to add them in with the nut butter. 

Secure the blender. Luckily, theOster Blend Active Portable Blender was created with user error in mind (those that forget to secure the blender lid and smoothie goes flying all over your perfectly white walls and ceilings) because the magnetic safety design ensures blades only run when the lid is on so it won’t turn on until the two little dots on the cup and the lid are lined up and secure. 

Blend. Push the little button two times, flip the blender over and let it go. If it looks like the smoothie is getting stuck, flip it over one more time and give it a shake. Repeat until the coffee smoothie is completely blended. 

Substitutions and Tips and Tricks for Recipe Success

  • This is not a cloyingly sweet smoothie. If you want it sweeter, simply add more honey or dates. 
  • Use any nut butter you like. We love cashew butter, but almond butter, peanut butter, or sunflower butter work great. 
  • For extra indulgence, add in a little bit of Nutella. 
  • For a hint of warmth, add in a dash of ground cinnamon.
