Peanut butter smoothie

Here’s the tastiest, best drink that happens to be healthy, too: a peanut butter smoothie! You can swear off milkshakes for good, because this smoothie is just as satisfying. It’s got the best pure peanut buttery flavor, and the silkiest, creamiest texture. Even better: all you need is 3 ingredients (plus ice)! It’s easy to make vegan or plant-based, and it’s the perfect breakfast or snack. We even serve it as an after dinner treat! Here’s how to make this easy recipe…and why you won’t be able to stop slurping it.

Why it’s the best peanut butter smoothie

Some peanut butter smoothies are just good: but this one is great. What makes it so special?

  • It’s got pure, sweet flavor. It’s perfectly peanut buttery and banana forward.
  • It’s got a silky smooth, creamy texture. Just the right thickness for sipping!
  • It’s full of healthy ingredients. There’s no added sweetener: just natural ingredients.
  • It’s easily plant based. It calls for just ¾ cup of milk, which can be non-dairy milk of your choosing!

Ingredients in this peanut butter smoothie

You could also call this a peanut butter banana smoothie. And right there, the name tells you most of the ingredients! This healthy smoothie is so easy, you might have all the ingredients already on hand. Here’s what you need:

  • Peanut butter: Naturally! Look for an all natural peanut butter without added sugar or oil, if you can.
  • Ripe bananas: All you need are 2 ripe, room temperature bananas! Many smoothie recipes call for frozen bananas, but that requires advanced planning. We never remember to put bananas in the freezer, so we customize our smoothie recipes to use room temperature.
  • Milk: The milk helps it blend and melds into the creamy texture. You can use dairy milk or non-dairy (keep reading for some options).
  • Ice: Ice completes the frothy texture!

Make it plant based! Non dairy milk options

You can use whatever milk you have on hand to make this peanut butter smoothie! It’s easy to make a vegan smoothie by using a plant based milk. Here are some of our favorites to use in smoothies:

  • Oat milk: The flavor is sweet and it has a nice creamy texture (a favorite!)
  • Almond milk: A little closer to water in its texture, but it’s popular and easy to find
  • Coconut milk: Super thick and adds a strong coconut flavor. If you want a coconut vibe, use it here
  • Soy milk: Has a nice sweet flavor and thick texture.

Variations and mix ins

Want to vary the flavor in this peanut butter smoothie? Here are a few ways to change it up:

  • Make a Chocolate Peanut Butter Smoothie. Add 2 tablespoon cocoa powder, then add 1 to 2 tablespoons maple syrup or honey to sweeten.
  • Change the nut butter! Make it an Almond Butter Smoothie with almond butter, or a Cashew Butter Smoothie with Cashew Butter.
  • Add vanilla. Just ½ teaspoon vanilla extract makes it taste like a milkshake.
  • Throw in coconut. Throw in a handful of coconut (or toasted coconut) for another flavor.

Smoothie storage

Smoothies are best eaten immediately. But this peanut butter banana smoothie actually lasts 1 to 2 days refrigerated! The flavor is best when it’s freshly made, but it stores well too.

Store it in a sealed container or a mason jar with the lid on. It may separate, which is perfectly natural. Just shake it up and you’re good to go! It’s nice to make this smoothie in advance so you can have breakfast or a snack on demand.

This peanut butter smoothie recipe is…

Vegetarian and gluten-free. For vegan, plant-based and dairy-free, use non-dairy milk.

  1. I tried the peanut butter smoothie and absolutely delicious and simple. My new go to dessert craving buster for sure.

  2. Amazing! I made the chocolate peanut butter version in my Ninja by just adding cocoa powder. By using frozen bananas, it comes out just like ice cream. I’ll put this into my banana “ice cream” recipe rotations.

    1. You could substitute 1 cup frozen mango, frozen pineapple, or fresh diced apple for each banana. Good luck!

  3. I used crunchy peanut butter and it wasn’t great, but with creamy peanut butter it’s really good. Any reason why?
