Extra flavor, extra protein, extra happiness

It’s time to ditch your regular afternoon pick-me-up in favor of this upgrade: the coffee protein smoothie. Not only is it a nutrient-packed alternative, this coffee beverage also tastes like a refreshing milkshake. It’s just way healthier!

These smoothies are made using cold coffee and lots of ice (and frozen banana) for an ice cold result sure to cool you down and fill your belly with protein. It provides sustainable energy, so you’re less likely to crash.

You’ll need 7 simple ingredients (one being ice) and 2 minutes, and your iced coffee smoothie will be ready in no time. As mentioned above, it’s the perfect afternoon pick-me-up to help you get through the rest of your day. But, it also makes a great breakfast and is the perfect post-workout meal!

Ingredients in this coffee banana smoothie

Ready for the coffee banana protein smoothie of your dreams? Good, because it’s about to happen! You’ll need the following 7 ingredients to get started.

  • Coffee: Coffee is the star of the show! You’ll need 2/3 cup (it should be cold).
  • Ice: Next, ice things up with 6-8 cubes. This will give the smoothie a tasty, refreshing consistency.
  • Banana: For flavor and thickness, include 1 frozen banana! Since frozen, this will also contribute to the icy texture.
  • Cocoa powder: Next up, include 1 tbsp of cocoa powder for a sweet chocolatey touch.
  • Almond butter: For thick buttery protein, add 1 tbsp of almond butter.
  • Protein powder: Then, we’ll take the protein even further by throwing in 1/4 cup of powder. Use whatever type you prefer. Unflavored or chocolate will most likely be best!
  • Chia seeds: Finally, add 2 tbsp of chia seeds as the final touch.

Tools needed to create your own coffee smoothie

This recipe keeps everything simple, and that extends ot the tools needed to create it. First, you’ll need a blender and spoon (for scraping down the sides if needed). After that, you’ll just need a few measuring cups: 1 tbsp, 1/4 cup, and 2/3 cup. That’s it!

How to make a coffee protein smoothie

Healthy coffee smoothies couldn’t be simpler to make – just blend and enjoy! In less than 2 minutes, you’ll have a refreshing, energizing cup of ice cold banana cocoa deliciousness.

Add all of the smoothie ingredients to a high speed blender.

Blend until completely smooth, letting it run for about 15-20 seconds.

If the smoothie is too thick, add more coffee or almond milk.

Serve immediately.

How many servings are in one recipe?

This recipe makes one delicious, heaping serving! You can easily double it to make a two-person recipe. If wanting 3+ servings, I recommend making them separately. You don’t want the blender to be too full!

If you liked this recipe, you’ll want to try these!

In the mood for some more recipes like this one? Here are some of my favorites for all things coffee and protein! Between coffee cake and protein treats, there are so many tasty ways to sneak both ingredients into your baking.

    I was really pleased with this recipe because I’m not a fan of protein powder but my doctor is really want me eating more protein so this very nicely covered up the texture of the protein powder!

    This sounds like the perfect summer breakfast smoothie to take in a thermos to an early nursing shift! Just wondering though why the protein grams are so low. According to Google the chia and almond butter alone have 7 g of protein, and most protein powders have a ton of protein in a quarter cup. How does it come to just over 14 g? Asking because I need close to twice that much protein for a smoothie to keep me filled up. This does sound so yummy!

    I added a bit of whole milk to top off the liquid to make a full 8oz for the protein powder to mix with. Amazing flavor!

    What brand of cocoa powder do you use? I’ve purchased some cocoa powder and it’s dark, unsweetened and bitter. Help!

    Made this today as I was craving a holiday mocha but needed some breakfast. It was delicious and kept me full for quite a while! I used vanilla protein powder as that’s what I had on hand it was still very good.

    This is incredible! I love replacing the almond milk that I normally use with cold brew – I use Trader Joe’s in a can. I’ll be making this every day!!
