This high protein powerhouse blueberry kale smoothie is full of antioxidants and plenty of protein to keep you full and satisfied until your next meal.

It’s time for me to come clean: my morning smoothie is rarely beautiful. But what it lacks in beauty it more than makes up for in taste, I promise. My secret? CINNAMON! Yes, cinnamon. Why should oatmeal have all the fun?

Cinnamon is good for you
Cinnamon is my favorite thing to add to a smoothie. Not only delicious but it adds a subtle, spicy balance to the sweet fruit. I have three reasons as to why cinnamon is a good addition.
- Helps Control Blood Sugars: When paired with high-carb foods such as fruits it can actually counter-balance any spikes in blood sugar. As a result, your energy levels will remain stable and you won’t experience that post-meal crash.
- Boosts brain power
- Rich in antioxidants
I use cinnamon in a few of my other favorite smoothie recipes like Apple Peanut Butter Smoothie, Peanut Butter Banana Oatmeal Smoothie, and Gingerbread Cookie Smoothie.
Kale and Blueberries in smoothies
Kale is an amazing superfood and is regarded as a nutrition powerhouse. This leafy vegetable contains high amounts of vitamins A, K, and C along with numerous other benefits such as preventing heart disease, lowering cholesterol, and providing bone health.
Blueberries are packed with antioxidants and phytoflavinoids. Phytonutrients are not essential but may help reduce disease and cancer. Blueberries are also high in potassium and vitamin C, making them anti-inflammatory as well.

Frequently asked questions:
What kind of kale is good for smoothies?
Traditional chopped kale is perfect for smoothies. I suggest not using lacinato kale as it has a bitter taste to it.
How do you blend kale smoothly?
Utilizing a high-speed blender such as a Blendtec, Ninja or Vitamix will ensure your kale is well blended into a smoothie. When blending I would not recommend kale stems in smoothies as it would make the end product taste bitter.
How do you adjust the thickness in a smoothie?
If you need to adjust the thickness of a smoothie, add more or less ice to reach the desired thickness. The amount of water you will need will depend on whether you are working with fresh or frozen fruit. I typically add 1/2 cup water with the protein powder as a way to get the smoothie going in the blender but it is optional.
This smoothie has over 17g of protein so it’s a great choice to stay full throughout your busy day.

Hi Liz,
Thanks for sharing this amazing recipe! My daughter got braces recently and I had to figure out a way to feed her veggies easily. It started off as a smoothie for her, but now our entire family loves this drink. I’ve made it three days in a row and need to head to the grocery store to get another head of kale… Absolutely delicious! :)
Absolutely creamy and delicious! I was so skeptical of the kale but I had half a bag leftover I needed to use. I found this recipe googling “ways to use up leftover kale” and it did not disappoint! I shared with my mom and sister. The cinnamon is perfect. I am stunned to say it is probably the best smoothie I have ever made at home. Thank you for the recipe!!
I have never left a review on a smoothie – or any food for that matter – before, but I had to on this one. I looked up a good kale smoothie recipe last week as a way to get rid of some kale going old for my post-workout smoothie, and I can’t stop making this now. It’s great protein and taste, and since I don’t add ice (using frozen blueberries instead), it’s the perfect thickness for my preference. It always creates the perfect single serving (again, because I don’t use ice) and allows me to use pre & probiotic plain yogurt for some extra gut-friendly nutrients. 6/5 stars on this one!
Thank you so much for your kind words! Glad you enjoyed it!
This looks like a recipe that I would really like. I have never purchased protein powder and would like to know which one you would recommend?
I love this! It came out so good. Next time instead of yogurt could I add almond milk? Trying to stay on track and enjoy the little things is crazy hard! But god this is so good. Only having half now and half later
You could definitely use Almond milk or Coconut milk, it will change the consistency though. Honestly, I like using plain Greek yogurt because it ups the protein and adds lots of healthy probiotics and healthy fats to the smoothie!
Homemade almond milk would be best.
This was very good I would definitely make it again
My son wanted more! Thank You!
That makes me so happy thanks for sharing!
It’s difficult to find a smoothie that is both healthy and delicious – this recipe nails that on the head! It’s got the right amount of sweetness from the banana and blueberries combined with the health benefits of all the ingredients. Using low fat coconut milk rather than yogurt left mine a little on the thin side so I added a tablespoon of natural peanut butter to thicken it up and another handful of ice. With and without the peanut butter were both delicious. Thanks for sharing!
I’m so glad you enjoyed it Greg! One of my favorites too!
How many is one severing. I end up after following about 40 oz. It is really tasty. An how long would keep in the fridge.
The serving size depends on how much ice you add I’m afraid! In terms of keeping in the fridge, I recommend enjoying right away. You can always put the ingredients in the blender first though and then blend later with ice?
