Peanut Butter Banana Smoothie FAQs

Do you want to make a different variation of this smoothie? Maybe substitute the bananas or peanut butter? Or make it thicker?

It might help if you went through the following answers to the frequently asked questions about peanut butter banana smoothie.

1. How Do I Thicken Peanut Butter Banana Smoothie?

A good smoothie should have a thick, milkshake-like texture. It’s the reason I use frozen bananas and ground flax seeds in this recipe.

Frozen bananas make this smoothie incredibly creamy. That’s why I always recommend keeping a couple of ripe bananas in your freezer all the time.

The ground flax seeds will thicken when mixed with liquids. And the good thing about flax is the fact that it doesn’t add much flavor to the overall treat.

Flax is also a great source of omega-3 fatty acids and fiber. Other ways to thicken the smoothie include adding a handful of ice cubes and blending until smooth.

2. What Other Fruits Go Well with Peanut Butter?

If you don’t like bananas, or if you’re looking to make a different variation of this smoothie, you could try using frozen blueberries or strawberries.

And to sweeten your blueberries/strawberries banana smoothie, you can add a tablespoon of honey or a pitted Medjool date.

3. What Other Variations of this Smoothie Can I make?

Other variations that you can consider trying include chocolate peanut butter smoothie or PB&J Smoothie.

TIP: If you don’t mind turning your peanut butter banana smoothie into green color, you can add a handful of fresh spinach. It gives you even more nutrients without changing the flavor!

And, if you don’t like peanut butter, you can try using sunflower seed butter or almond butter instead. They’re also very healthy and tasty!

4. Can You Use Overripe Bananas in Smoothies?

Ripe bananas with lots of brown spots are great for smoothies. Just keep in mind that the flavor of the banana will be transferred to your smoothie.

As such, you want to ensure the flavor is still appealing. I wouldn’t recommend using overripe bananas if the skin has turned brown-almost-black in color, I’d instead use them for baking.

5. Can I Make Peanut Butter Banana Smoothie with Yogurt?

Yogurt is a perfect addition to all smoothies since it’s not only packed with proteins and calcium, but it’s also great for enhancing healthy gut bacteria.

I recommend using any kind of Greek yogurt (vanilla, plain, etc) in this peanut butter banana smoothie recipe since it has a slightly tangy flavor.

Health Benefits: Is Peanut Butter and Banana Good for You?

Absolutely YES! Peanut butter and banana are an awesome combination. 

Not only do they possess flavors that complement each other, but they also offer some great health benefits.

For starters, peanut butter is about 25% healthy protein, which might tell the reason why bodybuilders and fitness enthusiasts include it in their diet!

It’s a great source of protein that is essential for repairing and building muscles. Furthermore, it’s a good source of other nutrients like vitamin E, magnesium as well as antioxidants and monosaturated fats.

Bananas, on the other hand, are a great source of fiber. Eating bananas will make you feel full but without consuming that many calories. 

Needless to say, bananas not only help in lowing the risk of heart diseases and blood pressure, but they’re a great source of potassium, which is essential for kidney function.

Fun Fact: Peanut butter banana smoothies make such a great healthy breakfast or post-workout snack, you get extra fiber and protein but with fewer calories!
