This Peanut Butter Banana Smoothie tastes like a milkshake, but it’s made without any added sugar. The ratio of ingredients below gives you the perfect texture every time!
If you’re trying to cut back on added sugar, but you want to enjoy something sweet, this smoothie recipe is the perfect solution. It’s filling enough to make for breakfast, or you can share it for an easy snack.
Using frozen banana is key to this recipe, as it gives the smoothie an ice cream-like texture. Paired with peanut butter and ground flax seeds, this smoothie packs extra protein and omega-3 fatty acids in each sip.
Ingredients You’ll Need
All you need is a few simple ingredients, including frozen bananas (yes, frozen is key!), peanut butter, and a little liquid to make this smoothie recipe come together. Be sure to freeze ripe bananas, with plenty of brown spots on their skin, to achieve a sweet flavor.
Flaxseed adds filling fiber and helps the shake thicken up even more, but you can omit these if you don’t keep ground flax on hand. Chia seeds or rolled oats would also make an excellent add-in for thickening purposes. Feel free to use cashew butter, almond butter, or any other nut butter you have on hand.
Add a scoop of protein powder or Greek yogurt for extra protein, or switch up the flavor by adding cocoa powder or a dash of cinnamon. You can customize a smoothie with any add-ins you like!
Pro Tip: Be sure to remove the peel before freezing bananas. The peel is difficult to remove after freezing.
How to Make a Peanut Butter Banana Smoothie
Slice a frozen banana into small chunks for easier blending. Then add the banana pieces, peanut butter, ground flax seeds, vanilla extract, and almond milk to a high-speed blender.
Secure the lid and blend until very smooth, which takes about 60 seconds. You may need to use a tamper to keep everything blending smoothly. If you need to add an extra splash of water or milk, add just 1 tablespoon at a time, so the smoothie doesn’t become too runny in texture.
For a thicker smoothie texture, add a handful of ice to the blended smoothie. Secure the lid and blend again, until the ice is pulverized, with no visible chunks remaining.
Adding ice cubes will dilute the flavor slightly, so don’t add too much at once! You can always keep adding more if needed. This is a good option if you prefer to enjoy your smoothie with a spoon, rather than sipping it through a straw.
Serve this creamy peanut butter banana smoothie right away, for the best flavor and texture. Pour it into a glass, or serve it as a smoothie bowl with your favorite toppings, like a handful of peanut butter granola, hemp seeds, or sliced banana.
Any leftover smoothie can be poured into an ice pop mold and stored in the freezer if you want a frozen treat for later. Or, you can store it in the fridge for up to 48 hours, if you don’t mind a more runny texture later.
Frequently Asked Questions
Yes, of course! You can use any non-dairy milk like oat milk, coconut milk, soy milk, or even just plain water for blending this smoothie. (Regular milk works, too, if you don’t need a dairy-free recipe.) The combination of peanut butter and frozen banana provides a creamy texture, so the liquid isn’t a big deal in this case.
Feel free to add in a big handful of spinach to this smoothie, if you don’t mind it having a green hue. The spinach won’t affect the peanut butter smoothie flavor, so it’s a great way to get more leafy greens into your life. (If you prefer to use kale, try my Tropical Kale Smoothie, instead.)

You can add a squeeze of honey (but it’s not vegan, FYI), a splash of maple syrup, or a pitted date to this recipe, for a sweeter flavor.

Ingredients
- ½ cup almond milk (or water)
- 1 frozen banana , cut into pieces
- 2 tablespoons natural peanut butter
- 1 tablespoon ground flax seeds
- ½ teaspoon vanilla extract
- Handful of ice (optional; to thicken)
Instructions
- In a high-speed blender, combine the almond milk, frozen banana, peanut butter, flax seeds, and vanilla. Blend until very smooth, stopping to scrape down the blender as needed.
- At this point you can make adjustments, adding an extra tablespoon of water or milk if the smoothie isn't blending well, or you can add a handful of ice cubes to help it thicken up into more of a slushy texture. Just keep in mind that additions will dilute the flavor slightly, so keep them to a minimum. You can also add a squeeze of honey, or a splash of maple syrup, for extra sweetness.
- Once the smoothie is blended, it's ready to serve right away for the best taste and texture. Top with extra sliced banana or a drizzle of peanut butter, if you'd like.

This is freaking amazing!! Exactly what I was looking for. I didn’t have flax so I added hemp hearts instead. It is SO smooth!! Delicious, will make it again. Maybe even later today.
Delicious!! I skipped the flax and used a bit less liquid and it came out sooo thick and creamy! 🤤
I just had this for breakfast. I was a little skeptical. I wasn’t sure if I would like a drink with peanut butter, but it was so yummy! Thanks!
Such a great recipe!!! I sometimes will leave out the vanilla and add coco powder to make it chocolate flavored. The texture of this shake is my fav!
This was so good! Just PB, Almond Milk, Vanilla Extract and Banana. Couple of Ice cubes and it was the perfect texture and taste. I may try on TBSPN of PB instead of two for a little less PB taste.
Oh and Flax seed!
This Smoothie is really awesome, the taste is much sweetie, then it’s regular way. Try it’s great
I’m using the smoothie setting on my breville mixer and followed the directions and came out with a not as thick 3/4 cup of smoothie. The picture looks like a tall cup. It says add ice to thicken but my smoothie turns ice into water and I have a watery smoothie. Why aren’t more people having this issue?
Could it be the blender you are using? Make sure you follow the recipe to the T. I did, but only added two ice cubes and it was the perfect texture. Not too thick and not watery
Can you use an unfrozen banana?
I used unfrozen and it worked great.
By far the best and most filling smoothie! I’ve been making it at least twice a week for the last few months and it never fails to amaze me. (I don’t add ice)
Tasty! Left out the seeds on my husband’s since he’s recovering from dental surgery. He loved it. Already made the request to have another tomorrow. 🙂 Perfect texture.
