This healthy recipe for a peanut butter banana strawberry smoothie is made with a nutritious blend of ingredients that are not only great for you but taste great too. Once you’ve gathered your milk, bananas, strawberries, peanut butter, flaxseed, and protein powder, the next step is throwing it all into a blender and pushing a button -and that’s it! A sweet and satisfying strawberry banana smoothie in seconds!

If you happen to have an Osterizer Classic Beehive Blender, there’s no need to use blender containers. Use my mom’s brilliant hack, and blend everything in mason jars. I’m not sure if it’ll work with other types of blenders, but if you have a mason jar lying around, it’s worth a shot.

Now let’s jump into the details of my kids’ absolute favorite smoothie recipe. Seriously. They request a peanut butter strawberry smoothie almost daily!

Ingredients You’ll Need

  • Non-Dairy Milk: For the smoothie base, use any milk alternatives (almond, coconut, soy, oat, etc.). If you can tolerate dairy, feel free to use regular milk.
  • Banana (frozen): You can use store-bought frozen bananas or freeze your own. You can also use a fresh banana. However, you may need to add ice to the blender. Frozen fruit creates a perfect smoothie consistency.
  • Strawberries (frozen): Strawberries make this smoothie taste like a PB & J! You can use fresh strawberries instead of frozen, but your smoothie won’t be as frothy. If you use fresh strawberries, adding ice to the blender will help thicken it up. Again, I highly recommend frozen!!
  • Peanut Butter: Natural, creamy peanut butter or PB2 powdered peanut butter work great here. Feel free to swap out peanut butter with almond, cashew, or sun butter.
  • Unflavored Protein Powder: You can use any unflavored protein powder here. For a vegan version, be sure to use a plant-based dairy-free protein powder.
  • Sweetener: Use your favorite natural sweetener to sweeten up your smoothie. Maple syrup, agave nectar syrup, date syrup, honey, stevia -whatever works for you. For a sugar-free smoothie, you can omit the sweetener completely.
  • Flaxseed: Add flaxseed for extra fiber. You’ll never know it’s there.

How To Make a Strawberry Banana Smoothie with Peanut Butter

Recipe Tips

  • Thinning your smoothie – If your smoothie is too thick, add a splash of milk and reblend at high speed until your desired consistency is reached.
  • Thickening your smoothie – Using frozen fruit is an excellent place to start when it comes to making a thick, frothy smoothie. You can also add more peanut butter, protein powder, or flaxseed.


  • Spices – When customizing this recipe, the options are endless. To warm up the flavor, add dashes of cinnamon and nutmeg.
  • Avocado – Add half of a ripe avocado for the healthy fats and the added creaminess.
  • Fruit – Feel free to add other frozen fruits like blueberries, raspberries, blackberries, cantaloupe, mango, and pineapple.
  • Veggies – This smoothie is so sweet and delicious that sneaking in veggies is super easy. Frozen or fresh spinach, kale, zucchini, and riced cauliflower are great options.

Storing & Freezing

Storing: Fill a container with a tight-fitted lid to the top to keep air out and store it in the fridge for a day or two. Your smoothie will probably separate, so stir it before enjoying.

Freezing: If you don’t plan on enjoying your smoothie immediately, it’s best to freeze it for later. Pour your strawberry smoothie into a freezer-safe container or bag and freeze for up to 3 months.

Recipe FAQ

Are strawberry peanut butter banana smoothies good for you?

Absolutely. Strawberries are a fantastic source of fiber, vitamins, and antioxidants. Peanut butter is packed with protein and healthy fats, and bananas are a great source of potassium. This recipe, in particular, also includes added protein and fiber-rich flaxseed.

Can you use yogurt instead of milk in smoothies?

You can use either yogurt or milk in smoothies. However, a smoothie made with yogurt will be much thicker than a smoothie made with milk. Another option is using equal parts of milk and yogurt to create the perfect consistency right in the middle.

How do I make a strawberry peanut butter and banana smoothie bowl?

Cut out about a 1/4 cup of milk to make a thicker smoothie. Serve in a shallow bowl topped with sliced banana, strawberries, a drizzle of peanut butter, and a drizzle of stevia.

  1. What a great idea to use a mason jar for single servings! What a clever idea your momma had. I’m going to have to get me some of these. And the Peanut Butter Banana Smoothie sounds delicious!

  2. 5 stars
    Since Amee posted this on instagram, I’ve been making this almost every morning to up my much needed protein intake. I feel SO much better overall!!! I bought the Isopure unflavored whey protein Amee recommended to me and it’s great (no flavor or sweetener, blends easily, etc.) It’s delicious and fun to try the variations. Mine: I use about 3/4 cup low-fat greek yogurt (for a dose of probiotics) with about 1 cup soy milk (with calcium), I add in 2 giant handfuls of spinach or baby kale, I use the PB powder & don’t add any sweetener. All else is the same (1/2 frozen banana, assorted berries, flaxseed, protein). I blend with immersion blender & it makes about a pint. It gives me long-lasting energy & keeps me from scrounging for “snacks”! Thanks Amee!! 🙂
