Ingredients for Banana Peanut Butter Protein Smoothie
Overripe Bananas: Pick very ripe bananas that have plenty of brown spots for the best results!
If you are using room temperature bananas instead of frozen bananas, be sure to add a couple ice cubes to the smoothie so that it is nice and cold.
Creamy Peanut Butter or Crunchy Peanut Butter: I use natural peanut butter or unsweetened peanut butter. You can also use peanut butter powder to keep the flavor but reduce the fat.
Milk of Choice: I use unsweetened almond milk, but oat milk, cashew milk, coconut milk, soy milk, or regular milk all work. To add more protein you can also use Greek yogurt for a portion of the liquid.
Rolled Oats or Quick Oats: Oats are highly satiating, which is why I love adding them to smoothie recipes. I like my smoothies to be filling so that I stay full for a long period rather than getting hungry right away.
I also like that the oats provide more texture so that the smoothie has more of a banana bread vibe.
Protein Powder: Pick your favorite protein powder! I like using unsweetened unflavored goat whey protein, but any kind works.
If you use a flavored protein powder, I recommend vanilla, chocolate, or peanut butter flavored. For vegan protein, use pea protein or hemp protein powder.
Chia Seeds: Adding a boost of omega 3 fatty acids and some plant-based protein, chia seeds are an easy addition to any smoothie recipe. You can also add hemp seeds or flax seeds if you prefer.
Pure Vanilla Extract (optional): A splash of warm flavor comes with vanilla extract. If you don’t have it on hand, feel free to skip it.
Ground Cinnamon: I love adding a dash of ground cinnamon for that banana bread vibe and extra flavor.
Recipe Customizations:
- Toss in some pure maple syrup or chocolate chips for a more decadent dessert smoothie or shake.
- Add one tablespoon of cocoa powder to make a chocolate banana smoothie.
This is not a low-sugar or low-calorie smoothie. But for those who like to begin the day with a filling smoothie, this recipe’s perfect for you.
It’s the ideal delicious breakfast for busy mornings!
Let’s make it!

How does this come out to 39g of protein? Can you gave a breakdown for what you use? I’m coming up with roughly 15g.
Hi there! Thanks so much for catching that – I had forgotten to add protein powder to the list of ingredients. I generally use 2 scoops of a vanilla protein powder. Still, when I re-calculated the macros I’m now getting 31 grams of protein instead of 39, so I’m not sure what brand of protein powder I was using back then to get the 39. Nevertheless, if you add in protein powder, it will bump up that protein count for ya 😉
@Julia, thank you! Glad I could help 😊 lol
Hi!
Is this a good alternative for dessert for someone who is diabetic?
Hi Marisa,
I’m not a doctor, but based on my limited knowledge of Diabetes, I don’t believe it would be a good fit. Fructose tends to spike blood sugar rather quickly and even though oats are a complex carb (slower burning), they raise blood sugar as well. I hope that helps! xoxo
Nice, can I premade this and leave it overnight for next day’s consumption?
I would think you could make it the night before, but I think it’ll taste best fresh 🙂
Who has two too-ripe bananas sitting on her counter and NOW KNOWS HOW TO USE THEM!? I’m so excited.
I just made this smoothie this morning. It was excellent!
I’m so happy you like it, Deborah! It’s one of my favorites! 😀
haha I definitely love me some banana bread! In fact I currently have some bananas sitting on my counter waiting until they get nice and ripe! 🙂 And I’d definitely be down for drinking my banana bread in smoothie form!
Ah heck yes, get thy bananas into thy blender! 😀
I’m with you, banana bread is the shit! 😉 Funny enough, right before I read this post, I looked at my fruit basket & decided I was going to make banana bread today…I could also go for this smoothie right about now!
Mmmmmhmmmm! This is the perfect use for those bananas…I was seriously tempted to bake a batch of banana bread to enjoy alongside this smoothie but then the little voice in my head that tells me when I’m being a lunatic chimed in. There’s no end to the obsession 😉
I feel you on the banana bread sitch. It’s like natural prozac. You can’t be upset when you got banana bread!
I love that you thought to put those flavors in a protein packed smoothie. And calories schmalories. If it’s made with whole foods then none of that nonsense matters. I would dunk the shit out of my banana bread in this smoothie and then slurp the whole thing down. 🙂
I love the way you think! And now I’m craving a hefty loaf with which to dunk 😉
