Yes, yes, they do! And blending them into a creamy smoothie might just become your new favorite way to enjoy these two morning staples.

It’s naturally sweet from ripe banana, packed with protein from Greek yogurt, and quick to make. I like to blend one up on busy mornings when I want something easy to take with me that’s full of bold coffee flavor.

Ingredient Notes & Tips

Cold Brew Coffee Concentrate
Adds bold coffee flavor without watering down the smoothie. I use Starbucks cold brew concentrate, which is easy to find in the coffee aisle of most stores.

Frozen Banana
Use a ripe banana with some black streaks on the peel—that’s a sign it’s sweet and ready for smoothies. Be sure it’s frozen, too. Frozen banana makes the smoothie cold and thick, so there’s no need for ice (which can water it down).

I slice ripe bananas into 1-inch chunks and freeze them. About 8 pieces equals one medium banana.

Triple duty: Frozen banana sweetens, thickens, and brings classic banana flavor to the smoothie!

Greek Yogurt
Plain, non-fat Greek yogurt adds both creaminess and protein. Full-fat or flavored yogurt also works, but I prefer plain so the coffee and banana flavors really shine.

Milk
A splash helps everything blend smoothly. I use 2% milk, but any kind works. For stronger coffee flavor, you can skip the milk and add more cold brew instead.

Sweetener (Optional)
If your banana is ripe enough, that might be all the sweetness you need. But feel free to adjust to taste with a little honey, maple syrup, or your preferred sweetener.

How to Make a Coffee Banana Smoothie

A blender is needed to make this homemade smoothie. It doesn’t have to be an expensive Vitamix, but it does need to be able to do a good job with frozen items.

I find that a powerful single-serve blender gets the job done easily.

Frequently Asked Questions

Can I use hot brewed coffee instead of cold brew concentrate?
I don’t recommend it. Cold brew concentrate adds bold coffee flavor without watering down the smoothie. Plus, adding anything hot can affect the texture and isn’t ideal when blending frozen ingredients.

Can I make this smoothie dairy-free or vegan?
Yes! Just swap the Greek yogurt for a plant-based alternative like almond, cashew, or coconut yogurt. Use your favorite non-dairy milk (like oat or almond), and you’ve got a vegan-friendly version.

What if I don’t have Greek yogurt?
You can use regular yogurt instead. Just note that the smoothie might turn out a little thinner, and it won’t have quite as much protein. Still tasty, though!

Can I add protein powder or other mix-ins?
Absolutely. A scoop of vanilla or unflavored protein powder blends in well. You can also toss in chia seeds, ground flaxseed, or even a pitted Medjool date for extra sweetness.

How long does the smoothie keep?
It’s best right after blending while it’s thick and creamy. If you need to make it ahead, refrigerate it in an airtight container. Just know the texture may thin out over time.
