Ingredients & Substitutions

Soy Milk: Or, go for any dairy-free milk of your choosing. However, keep in mind that soy milk is an excellent source of protein. Swapping it for something else may change the protein content in this recipe. 

Water: Or, use more soy milk.

Frozen Ripe Banana: FROZEN bananas will help yield a creamy and thick protein smoothie. It will also keep it cold without the use of too many ice cubes. You can use pre-packaged frozen bananas or freeze them yourself.

Cocoa Powder: We’re getting our chocolate flavor from cocoa powder! I personally love using Dutch-processed cocoa because it’s richer, darker, and less acidic. 

Chia Seeds: This will boost up the protein content in your smoothie while also adding plant-based fiber! 

Sugar: Optional. You may also use an alternative sweetener of choice. 

Peanut Butter: A great source of protein and flavor!  

Oat Bran: If you haven’t tried oat bran - you need to! It’s packed with protein and fiber and has many uses. For example, oat bran porridge. 

Ice Cubes:  You’ll just need 2-3 ice cubes. 

Tips To The Best Chocolate Peanut Butter Protein Smoothie

1. Go for a high-speed, quality blender. This will help get your smoothie perfectly creamy and completely blended. For a quality, affordable blender, I recommend an Oster Blender - which I use and love dearly! 
2. Depending on your preference for smoothie thickness (or thinness) adjust the amount of liquid added to the smoothie. For a thicker smoothie, add less liquid. For a thinner smoothie, add more liquid. 
3. Stick with frozen bananas! You might have fresh bananas laying around on your kitchen countertop, but it’s worth using bananas from frozen. Frozen bananas will give you a creamier smoothie texture and will keep the smoothie cold without the use of a lot of ice. 

Recipe FAQs

Is Peanut Butter A Good Source Of Protein For Smoothies

Peanut butter is a great source of protein! In 100 grams of peanut butter butter, there are 24 grams of protein. For the amount of peanut butter used in this recipe (1 tablespoon), there are about 4 grams of protein. 

Is Banana A Good Source Of Protein 

Bananas are an excellent source of plant-based fiber and carbohydrates. They are less known for their protein content. A medium banana has about 1.3 grams of protein. 

How To Make A Peanut Butter Chocolate Banana Protein Smoothie 

1. Pour all of your ingredients into your blender, starting with the liquids first. Then, blend until smooth and creamy.

Yes, it’s that easy! 

How To Freeze Bananas

There are two ways to freeze a banana and it depends on if you want to do the work now or later. I flip-flop both ways, depending on my laziness levels at the given moment. 

For any way you choose, I suggest starting with a very ripe banana. Ripe bananas become naturally sweet, which allows you to omit or reduce the addition of sugar/sweetener in the protein chocolate peanut butter smoothie. 

Freeze The Banana Whole 

Once the banana is ripe, throw the whole thing in the freezer. No additional steps are needed. If you plan on using the banana for a smoothie that same day, freeze it for at least 3 or so hours. 

Easy, right? The work just comes later - which is peeling the banana from frozen. 

Check out our 3 Ways To Unpeel A Frozen Banana. 

Unpeel & Cut Banana Before Freezing 

Unpeel a banana as you normally do. Once that’s done, cut up the banana into about ½-inch chunks. Place the piece on a plate and stick it into the freezer. No need to wrap or cover – just let them be cool, calm, and collected all on their own. 

Freeze for at least an hour.

If you are batch-freezing bananas, you can use a freezer-safe bag to keep things organized and make more space.
