This Peanut Butter Banana Smoothie is a quick and healthy recipe that’s perfect for breakfast, or an easy snack on-the-go. I love how ice-cream like bananas become when you freeze them, so when you blend them together with peanut butter it’s almost like you’re eating a decadent milkshake, but with no added sugar.
How to Make the Best Peanut Butter Banana Smoothie
You’ll need frozen bananas to make this recipe as written, so I recommend having a stash of ripe bananas ready-to-go in your freezer. When your bananas have lots of brown spots on them, make sure to peel them first, then place them in an airtight container with a lid and store them in your freezer to freeze overnight.
I usually have 10-12 bananas stored in my freezer at any given time, because we use at least 1 each morning for our daily smoothies. If you don’t have a high-speed blender like my Vitamix, I recommend slicing your bananas into smaller pieces (before or after freezing them) so they will break down faster.
Once you have frozen bananas on hand, all you need to do is blend them with peanut butter (you can use homemade peanut butter if you like), flax seed, and a little liquid. I like to start with as little liquid as necessary needed for blending, so this smoothie will have a thick texture. You can always add more as needed!
Can You Use Overripe Bananas in Smoothies?
I don’t know about you, but when I have overripe bananas on my counter, my first thought is that it’s time to make Coconut Flour Banana Bread. (Or Banana Oatmeal Muffins!) If your bananas aren’t totally black and mushy, I think it’s fine to use them in smoothies.
Remember, the flavor of the banana will transfer to your smoothie, so you want to make sure the flavor of the bananas are still appealing to you. Bananas with lots of brown spots are perfect for smoothies, but if the skin is getting borderline-black in color, I’d use them for baking instead.
What Can I Put in a Smoothie to Thicken It?
I think the best smoothie recipes are nice and thick, with an almost milkshake-like texture. That’s why I use frozen bananas in this recipe instead of fresh ones, and that’s also why I like to add a spoonful of ground flax seeds to the mix.
You can buy a bag of ground flax seeds in most grocery stores, making it a convenient smoothie addition. Flax thickens when it’s mixed with liquid, without adding much flavor to the overall drink. Plus, you’ll be getting some omega-3 fatty acids and extra fiber in each sip!
Are Peanut Butter & Banana Good For You?
Peanut Butter and banana are a classic combination, and with good reason. Not only do their flavors compliment each other well, they also have some potential health benefits!
- Bananas are a good source of fiber, so they are filling while being relatively low in calories. Bananas are also a good source of potassium, which is essential for kidney function, and may help to lower blood pressure and the risk of heart disease.
- Peanut Butter is about 25% protein, so it contributes 8 grams of protein to this dairy-free smoothie. Peanut butter is a good source of monounsaturated fats, antioxidants, as well as nutrients like magnesium, folate, and vitamin E.
If you don’t mind your drink turning green in color, try adding a handful of fresh spinach to this peanut butter banana smoothie. It won’t change the flavor at all, but you’ll get even more nutrients into your day!
What Other Fruits Go Well with Peanut Butter?
If bananas aren’t your favorite smoothie ingredient, you could make this smoothie with frozen strawberries or blueberries instead. It won’t be quite as sweet with only berries, so you might want to add a pitted Medool date or a tablespoon of honey for sweetness.
How to make a Peanut Butter Banana Smoothie (1-Minute Video):
This Peanut Butter Banana Smoothie tastes like a milkshake, but with no added sugar! It's a healthy breakfast or snack on-the-go.
In a blender, combine the water, banana, peanut butter, flax seeds, and vanilla. Blend until very smooth, stopping to scrape down the blender as needed. If you need a little more liquid, add it just 1 tablespoon at a time so the smoothie with have a thick, milkshake-like texture. (If you end up adding too much liquid, you can always add a handful of ice cubes to thicken it up again-- it will just dilute the flavor slightly.)
Taste the smoothie and adjust any flavoring to taste. If you need a sweeter flavor, you can add one pitted Medjool date or a tablespoon of honey. Serve right away!
