Growing up, I ate a lot of peanut butter and banana sandwiches and then when I discovered smoothies, it became a staple flavor for me! It’s just something about the sweet flavor of bananas mixed with the salty flavor of peanut butter. SO GOOD.

What is in a peanut butter banana smoothie?

  • Bananas: You can buy frozen bananas at most grocery stores, but if you can’t find them. No worries! You can make your own at home for super cheap.
  • Greek yogurt: Greek yogurt is a great addition to all smoothies because it packed with protein and has a slightly tangy flavor. Feel free to use any kind of Greek yogurt such as plain or vanilla.
  • Flax seeds: Ground flax is where it’s at when it comes to smoothies because they’re easier to digest that way!
  • Almond Milk: This peanut butter banana smoothie recipe calls for unsweetened almond milk, but any kind of milk or liquid will work!
  • Vanilla Extract: Don’t have vanilla extract on hand? No worries! You can just nix it 😀
  • Peanut Butter: We love using all-natural peanut butter in our smoothies because it’s creamy and has no additives. Our favorite brands include 365 and Smuckers.
