Peanut butter and banana have always been one of my favorite flavor combos. Years ago, I shared this peanut butter banana milkshake, and it's still one of my go-to treats. This smoothie is simply a high-protein twist on my classic favorite.
These days, I love turning dessert flavors into dishes that keep me full and use wholesome ingredients. This peanut butter banana protein smoothie tastes like a milkshake, but is good for me.
It works perfectly for a quick breakfast, an afternoon snack, or even a sweet treat when I'm craving something creamy and filling.
Why Make A Peanut Butter Banana Protein Shake
- Tastes like a treat. The pb and banana combo is creamy, rich, and will make you think you are drinking a milkshake.
- High in protein. Greek yogurt, milk, and protein powder give this shake a whopping 49g of protein.
- Quick and easy. Everything goes into the blender and mixes in under 5 minutes.
- Easy to change at any time of day. You can easily swap ingredients based on your needs for breakfast, lunch, or dessert.
Ingredients Needed
To make this easy peanut butter banana smoothie recipe, you will need the following ingredients. Scroll down to view the recipe card for ingredient amounts and complete instructions.

- Milk: Go ahead and use whole, 2%, or fat-free milk, or your preferred milk. I usually use Fairlife 2% for the extra protein.
- Greek Yogurt: Choose your favorite brand. I prefer Fage 2% plain Greek yogurt because it is high in protein and low in sugar. You can also use a vanilla-flavored yogurt for a slightly sweeter taste.
- Frozen Banana Slices: Provide the natural sweetness and thicken the shake.
- Natural Peanut Butter: A heaping spoonful kicks up the nutty flavor. If you want to reduce fat and calories, use a serving of PB Fit powder.
- Protein Powder: Adding a serving of peanut butter protein powder really boosts the protein content. I just tried the Ghost Nutty Buddy flavor, and it was good.
Optional Add-Ins
If you like to customize your protein shakes, here are a few ideas to change things up. Keep in mind that these additions will change the nutritional information.
- Spinach or Kale: A handful of leafy greens adds some extra vitamins. Trust me, you won't taste it.
- Chia Seeds or Flax Seeds: Increase dietary fiber intake.
- Cinnamon: Gives a warm, spicy flavor to the drink.
- Rolled Oats: Thicken the drink further and make it even more filling. Increase the liquid if you add oats.
- Honey or Maple Syrup: Add a drizzle if you like it sweeter or if your bananas are not fully ripe.
How To Make A Peanut Butter Banana Smoothie

- Add the milk, yogurt, and protein powder to the blender. Place the remaining ingredients on top.
- Blend until smooth and creamy. If the smoothie is too thick, add a splash of milk until you reach your desired consistency.
- Pour into 1 or 2 glasses. Drizzle the top with warm peanut butter and add a banana slice.
BruCrew Tip: This recipe makes one 12-ounce drink or two 6-ounce smoothies.
Smoothie Variations
You can easily mix this protein shake with whatever you have on hand.
- Make it dairy-free. Use an unsweetened non-dairy milk you like, such as coconut, almond, or oat milk. Add some dairy-free yogurt.
- Use a different nut butter. Try cashew or almond butter for a different flavor.
- Add a caffeine twist. Use cold brew coffee for part or all of the milk.
- Make a chocolate peanut butter smoothie. Use chocolate protein powder or a tablespoon of cocoa powder for a peanut butter cup twist.

Storing and Freezing
While this smoothie is best enjoyed immediately, you can keep extras in an airtight container in the fridge for up to 1 day. Add ice and blend again before enjoying the leftovers.
The mixture can also be frozen in freezer bags or an ice cube tray. Let thaw overnight in the fridge, then blend with ice to thicken.
BruCrew Tips
- Wait until your bananas are ripe and have spots before freezing them for the sweetest banana flavor.
- Keep frozen bananas in your freezer at all times. Slice bananas, then freeze them on parchment lined tray for 60 minutes. Place in a freezer bag and freeze for future shakes.
- Use a high-powered blender to blend the frozen fruit and ice better.
- Always pour the liquid in first. This allows the blades to better mix the ingredients.
- Adjust the texture by adding more or less liquid to your preference.
- Make a smoothie bowl. Thicken the mixture with ice and pour it into a bowl. Then top with banana slices, a drizzle of peanut butter, miniature chocolate chips, and peanut butter banana granola.
