This high-protein smoothie is an easy addition if you’re trying to increase your protein intake. It uses simple pantry staples and a frozen banana for sweetness.

As written, it’s vegan-friendly, but it’s also easy to customize.

Ingredients You’ll Need

Instead of protein powder, this recipe features a combination of plant-based protein sources, including hemp hearts (hulled hemp seeds), peanut butter, and your favorite milk. 

Adding a spoonful of your favorite nut butter adds creaminess and extra protein. I prefer the flavor of peanut butter, but almond butter  or sunflower seed butter will also work. 

You can also add any other mix-ins you like, such as chia seeds or oats.

Detoxinista Tip

Dairy milk has 8 grams of protein per cup, and if you need a dairy-free option, soy milk has a similar protein profile! (This will vary slightly by brand; this recipe assumes you’ll use an unsweetened version.) If you prefer coconut or almond milk, those will work, too, but you’ll get less protein per glass.

How to Make Protein Smoothie without Protein Powder

In a high-speed blender, combine:

  • 1/2 cup soy milk (or milk of choice)
  • 1 handful fresh baby spinach
  • 1 frozen banana, sliced into pieces
  • 3 tablespoons of hemp hearts
  • 1 1/2 tablespoons unsweetened cocoa powder
  • 1 tablespoon peanut butter or almond butter
  • ​1/2 teaspoon vanilla extract

Secure the lid and blend until smooth. You may need to stop and scrape down the sides of the blender to ensure even mixing.

If the smoothie texture looks runny, add a handful of ice cubes and blend again. This will give your smoothie a slushy texture.

Just keep in mind that the more ice you add, the more diluted the flavor will be—so don’t overdo it! 

Serve the protein smoothie right away for the best texture and flavor. Turn it into a smoothie bowl by topping it with extras, like chopped walnuts, cashews, or pumpkin seeds.

Frequently Asked Questions

What can I put in my smoothie instead of protein powder?

Hemp hearts have 10 grams of protein per 3 tablespoons. Greek yogurt has roughly 11 grams of protein in a half cup. A half cup of silken tofu has approximately 9 grams of protein. You can add any extras to taste. 

Can I use different fruit?

Bananas taste sweeter than berries, but you can use a half cup of frozen blueberries, raspberries, or strawberries, if you don’t mind a less-sweet flavor. You can also use 3 pitted Medjool dates as a sweet swap. 

How can I change the flavor?

Add a dash of cinnamon, if you like, or swap the milk. Coconut milk will give it more creaminess, but less protein. (Canned coconut milk can also thicken when blending frozen ingredients, so use the boxed variety that is sold in the refrigerated section.)

Notes

Nutrition information is for the whole batch. This information is automatically calculated using generic ingredients, so it’s just an estimate, not a guarantee.
Banana Tip: I like to freeze bananas whole and then slice them into pieces before blending. This makes them break down faster in a blender. Check out my How to Freeze Bananas post for more tips.
Update Note: This recipe was posted in June 2014 and updated in January 2025. The update adds a tablespoon of peanut butter, uses soy milk instead of water, and corrects the nutrition information. You can find the original recipe here.

  1. I highly recommend this shake for your chocolate
    fix! I had it for lunch yesterday, and it kept me full for hours. It is nice to have a high protein shake that doesn’t require protein powder. This recipe is definitely is a keeper!

  2. This was really good! I did frozen bananas and then some frozen zuchinni as well. Really good and creamy! Will make again 🙂

  3. This recipe was so delicious after a workout. I recently bought a huge bag of hemp hearts at my local Costco and have been intimidated to use it. This delicious recipe will be in my regular rotation from now on. Thank you for all the amazing recipes.

  4. This was good. I did subtract 1 T hemp and add 1 T choc protein powder. I also added a small scoop of beet powder. I had no spinach so I skipped it. Thanks.

  5. I was skeptical but this shake is delicious….so good in fact that I drank it so quickly I wanted to make a second one. Luckily I waited a few minutes because what I didn’t expect is that I’ve been really full for a few hours now – must be all the protein. This will be on my list of regulars to have now. Didn’t add spinach yet, may try that next time. Yummy – thanks.

    1. It has the best texture when you serve it right away. If you let it sit, it will still be edible, just not quite as enjoyable!

  6. Yum. Also, thank you for not putting avocado in e v e r y t h i n g. Some people (like me) are sadly allergy to it. Great web site. Really enjoying it and feeling inspired.

  7. Hi Megan,

    Your protein shake recipe is fantastic. I have featured it in our website Green Thickies.
    Of course all credits are given to you and linked back to this page. I have not posted the actual recipe, but only a small snippet from this page and one photo from here.
    Hope that is okay with you. Thanks a lot 🙂

    Katherine,
