Peanut Butter Strawberry Banana Smoothie


I’m here to bring you an amazing, nutritious, fresh smoothie recipe for you on this beautiful Monday to help you jump-start a wonderful week! This gorgeous smoothie recipe was part of our AK Smoothie Series last summer and I had to share it again because we filled that week with some of my favorite smoothies of all time.

If you grew up on deliciously sticky, sweet PB&J sandwiches with banana slices tucked in the middle, ohhh baby this smoothie has your name on it.

Say hello to my peanut butter strawberry banana smoothie made with just 4 ingredients that’s so delicious it may just knock you naked. You’ve been warned. I got the inspo from this amazing Peanut Butter Strawberry Banana Quesadilla, and the flavors are truly identical. The perfect amount of sweetness and flavor you know and love!

Four ingredient peanut butter strawberry banana smoothie

That’s right, this thick, creamy & delicious strawberry banana peanut butter smoothie is made with just 4 simple ingredients that you may already have on hand! Here’s what you’ll need:

  • Frozen strawberries: I recommend buying fresh strawberries when they’re at their peak ripeness and then freezing them for later. This will give your smoothies the best flavor!
  • Frozen banana: because PB&J’s are better with banana inside — don’t you agree?
  • Peanut butter: hello healthy fats and wonderful peanut butter flavor! I always opt for a natural, creamy peanut butter that’s just made with peanuts and salt. Use the code ‘AMBITIOUS15‘ to get 15% off of my fav nut butter brand, Wild Friends.
  • Milk: I like to use unsweetened almond milk in this smoothie recipe, but feel free to use any milk you’d like.
  • Optional add ins: feel free to also add chia seeds and/or hemp seeds for another boost of healthy fats, fiber and omega-3s. More nutritional add-ins below!

Want to change up the flavor?

You can! Feel free to swap the frozen strawberries for frozen raspberries, blueberries, or mixed berries. It will make the smoothie taste like a PB&J with whatever flavor of jam you like. Personally, I love a good seedy raspberry jam, so raspberries would be delicious in this smoothie.

Easy nutritional boosters

Looking to add an extra boost of nutrition to this peanut butter strawberry banana smoothie? Here’s what I suggest:

  • Flaxseed meal: this is one of my favorite ingredients to add to smoothies for a little boost of fiber and minerals, and is especially great for nursing mamas as flaxseed can help increase milk supply. Usually, a tablespoon is plenty! Here’s a brand I love.
  • Veggies: if you’re looking to get more greens in your smoothie, try adding a cup or two of raw or cooked spinach or kale. You could also try adding some frozen cauliflower for another boost of veggies — you’ll never be able to taste it!
  • Oats: to add a little heartiness to your smoothie and to help thicken it, feel free to add in 1/3 cup oats. Do not use steel cut oats as they will not blend well. This smoothie will really taste like a PB&J with oats blended in!
  • Avocado: add healthy fats and create a thick, creamy smoothie by adding ripe avocado. Usually 1/4 or 1/2 of an avocado will be sufficient and also help to keep you satisfied thanks to those healthy fats.
  • Protein: Easily add more protein to a smoothie by adding 1/2 cup of greek yogurt or 1 scoop of your favorite protein powder. I recommend Vital Protein collagen peptides or Four Sigmatic Plant-Based Protein Powder.

Reminder: you’ll likely need more milk than the recipe calls for if you add more ingredients. No worries! Just add a bit at a time and blend the smoothie until it’s nice and creamy but still thick.

Don’t forget these smoothie making tips

With a few tips & tricks you’ll have the perfect, thick and delicious strawberry peanut butter banana smoothie every time:

  1. Use frozen fruit. Using frozen strawberries and banana here is best as they help keep the smoothie cold and thick. Ice often waters down the flavor and doesn’t blend well, so it’s best to avoid adding it whenever possible.
  2. Add more liquid. As I mentioned above, don’t be afraid to add more milk if your smoothie is too thick or won’t fully blend. Adding mix-ins or using a smaller blender might require you to add more so that the smoothie blends nicely.
  3. Use your fav milk. Feel free to use any milk you’d like in smoothie recipes! Almond milk tends to have a neutral taste in smoothies, coconut milk will add a more tropical and creamy flavor, and regular milk will add a boost of protein. I think coconut milk would add delicious flavor to this peanut butter strawberry banana smoothie.

Recipe Notes

Buying fresh strawberries when they are at their peak ripeness and then freezing them gives the best flavor for this smoothie.
I love adding 1-2 cups of fresh spinach to this smoothie but it will change the color. The flavor will remain the same. See the full post for more ways to customize your smoothie.
Please note if you do add chia seeds, you may need to add more milk as it will thicken the smoothie after it sits for a few minutes.
