Blueberry Peanut Butter Protein Smoothie

Jump to Recipe

While I tend not to drink a ton of smoothies in the wintertime (fellow cold persons relate?), I’ve been making an exception for this salty-sweet combo.

Lately, I’ve revisited a smoothie that used to be my absolute favorite: peanut butter, banana, and berry. But instead of peanut butter, I’ve been opting for peanut butter protein powder and choosing wild blueberries for my fruit.

The combination is seriously dreamy and I’m hooked! Let us show you how easy (and delicious) it is.

Banana, blueberries, Amazing Grass protein powder, spinach, dairy-free milk, and seeds for making a delicious smoothie

This 5-ingredient, 5-minute, 1-blender smoothie starts with frozen banana for a creamy, sweet base with plenty of healthy carbs and wild blueberries for a serious dose of antioxidants.

For nut milk, we opt to make our own (check out our Guide to Dairy-Free Milk!) or grab store-bought almond, cashew, or coconut milk.

As for protein powder, we’ve reviewed so many! (Check out our Vegan Vanilla Protein Powder Review, Vegan Chocolate Protein Powder Review, and Vegan Flavored Protein Powder Review.) But we keep going back to this favorite from Amazing Grass (not sponsored — just love!). Their peanut butter protein powder is legit and boasts 20 g protein and 2 g sugar / serving. Highly recommend!

Last but not least is a handful of greens for some fiber and nutrients (we like spinach for its neutral flavor) and an optional sprinkle of Seed Cycling Mix.

This would make the perfect mid-morning snack, on-the-go breakfast, or midday treat. We especially love it for post-workout recovery.

  • To a high-speed blender or small blender, add banana, blueberries, spinach, protein powder, dairy-free milk (starting with the lesser amount), and seeds (optional) and blend on high until creamy and smooth, scraping down sides as needed.
  • Taste and adjust flavor as needed, adding more banana for sweetness or protein powder for peanut butter flavor. Add more dairy-free milk as needed to thin.

  1. James says

    Tried this but used organic pea protein and added about a tbsp of peanut butter. Also added vanilla essence. Was great! Going to add spinach to a lot more smoothies now! Can’t even taste it and it’s a great iron boost. Forgot to add the seeds.

  2. Anna says

    I loved this smoothie! I used Trader Joe’s peanut powder instead of the protein powder because that’s what I had on hand. I otherwise followed the recipe exactly. Perfect post-run smoothie–thanks for the recipe!

    I was really excited to try this smoothie, but it had a nasty taste I don’t care for …. must be the amazing grass pb powder.

    • Avatar for Dana @ Minimalist BakerDana @ Minimalist Baker says

      So strange. I LOVE that protein powder. Perhaps next time ditch the protein powder (or use vanilla/plain) and just stick with 1-2 Tbsp peanut butter :D

  4. suzanne says

    Very disappointed in this recipe, especially since we bought the recommended pb protein powder. Overly sweet with a chemical chalky taste. None of us could finish it. Hard to believe this is your favorite protein powder.

    • Avatar for Dana @ Minimalist BakerDana @ Minimalist Baker says

      So strange! Sorry it didn’t work out. I happen to love the taste of this powder. However, if it’s not for you, you can drastically reduce the amount or sub with your favorite vanilla or plain protein, and add 1-2 Tbsp PB for peanut butter flavor.

  5. Nina says

    Thanks for sharing this new smoothie idea! I have already been adapting your Blueberry Almond Butter smoothie with peanut butter and swapping out the berries from time to time to keep it interesting. I never thought to use peanut butter powder before! Will give this a try because I literally drink one of your smoothies every morning for breakfast on my long commute to work. More smoothie recipes please!!

    I have been looking for a way to use some powdered peanuts (called peanut flour). I think it’s pretty similar to peanut protein powder, just different packaging and without a scoop. Is a scoop about a tablespoon? More? Less?

    • Avatar for Dana @ Minimalist BakerDana @ Minimalist Baker says

      So, their scoop is closer to 4 Tbsp or more. But start with 1 Tbsp and work your way up as it will be a more potent peanut flavor.

  7. Kristine Genovese says

    What would you recommend for banana haters? So many creamy smoothie recipes that are peanut butter or chocolate-based tend to use bananas, and I wish I could even just tolerate them, but I can’t! Any ideas for a replacement?

      • Kristine Genovese says

        OMG I have a very ripe mango sitting on my kitchen table right now!! I will definitely give this recipe a try, and it never occurred to me to use avocado instead of bananas! Most things are too sweet for me anyway, so that won’t likely be an issue–thanks so much for this tip!!

    Made this as is and it is fantastic! Never would have thought to add blueberries to peanut butter and I like the powdered PB since it’s easier to get a nice, smooth blend. Also, this a GREAT video. Love the music, the pace, the photography. Nice job.

  10. Alanna says

    This sounds tasty. Do you have any tips to prevent blueberries from giving a smoothie a “gloopy” texture? Anytime I include them I run up against this unpleasant texture, and it makes me less likely to want to use them. Thank you.

    • Avatar for Dana @ Minimalist BakerDana @ Minimalist Baker says

      Hmm, I haven’t noticed that! Wild blueberries are my favorite b/c they’re denser in flavor and nutrition and would probably provide less of the “gloopy” texture you’re referring to.

      • Alanna says

        Thanks for your reply. It is wild blueberries that I use, too, but every time I include them I encounter this texture. Have read of others’ similar experiences elsewhere.

  11. Julia Cooke says

    Looks delicious. If just using regular peanut butter instead of protein powder, how much do you suggest including?

  12. Lucy says

    Do you have a recipe for “blender bombs”? I bought ready made ones, but seems easy to make on my own, just need the right proportions. Looking to add more protein and good stuff, like flax and hemp to my smoothies and the balls are super convenient.

    Thank you
