Smoothies are a great way to start your day, but having it the same old way can be boring after a while. To break the monotony, I often come up with different flavor combinations that work together well and include ingredients that my family already loves, such as peanut butter.

Most kids and adults love this nut butter and can’t get enough of it. This smoothie combines creamy peanut butter with bananas and oats to make a thick, delicious smoothie that tastes like a dessert (read milkshake). The best part is that it has no added sugar, just a handful of dates, which not only sweeten this drink but also provide nutrients, fiber, and antioxidants.

Ingredient notes/swaps

This banana peanut butter smoothie recipe is super easy to make and requires simple ingredients that you probably already have in your kitchen. So, let’s get started!

  • Bananas (fresh or frozen) – Use a frozen banana for a thick and creamy texture. Chop ripe bananas overnight and freeze the banana slices for at least 6-8 hours before using.
  • Storebought or homemade peanut butter – Different nut butter, such as almond butter or cashew butter, are great alternatives as well.
  • Whole milk or Greek Yogurt – You can also use non-dairy milk such as almond milk or oat milk instead of regular milk.
  • Seedless dates – Adds natural sweetness as well as protein to the smoothie. You can also use honey or maple syrup instead of dates.

How to prep ahead

To prep ahead for this peanut butter smoothie recipe, chop the bananas, place them in a freezer-safe bag, and freeze. Remove it from the freezer just before making the smoothie – no need to thaw.

Tips and Tricks

  • Use a high-powered blender like Blendtec or Vitamix for best results. You may have to run the smoothie cycle twice to get a chunk-free smoothie.
  • If using a regular blender, make sure to soak the dates in milk overnight or at least 20-30 minutes to soften it. 
  • Don’t toss those overripe bananas. Peel and chop them and put them in the freezer. Use it in this smoothie without thawing. Frozen bananas, when added to a smoothie, help make it thick and creamy.


Can we make this smoothie in advance?

Yes, totally. It tastes great for a day or two (at the max) in the refrigerator, after which it starts losing its taste.

Are peanut butter and bananas healthy?

Yes. Consuming a moderate amount of peanut butter and bananas is considered healthy as they offer a range of essential nutrients such as proteins, healthy fats, vitamins, minerals, and fiber. Make sure to use unsweetened, natural peanut butter with no additives to avoid unnecessary calories.

Do I need frozen bananas for the smoothie?

No. You can use fresh bananas. Frozen bananas not only make the smoothie frosty but creamy, too. You can always add ice to compensate but it’ll dilute the flavor a bit.

How can I adjust the thickness of the smoothie?

If you find your smoothie too thick, you can add a little more milk to reach your desired consistency. Alternatively, if you prefer a thicker smoothie, try reducing the amount of milk and adding more banana.

Can I add spinach to this smoothie?

Definitely. Add baby spinach since they are sweeter than mature spinach. You can’t taste the leafy greens but the color will definitely change.
