We love a breakfast smoothie, especially one that is packed with protein and fruit. This smoothie is made with blueberries, bananas, and peanut butter, which seems like a strange combination, but it is kind of like a drinkable peanut butter and jelly sandwich.

This protein-packed peanut butter blueberry banana smoothie made with frozen blueberries is a delicious and healthy treat for an afternoon snack or filling breakfast.

Smoothie Recipe Ingredients

Banana – I use a fresh banana with frozen blueberries. If you use a frozen banana, let it soften a little so your blender doesn’t get upset with you.
Milk – You can use dairy milk (I like to use whole milk), almond milk, or your favorite non-dairy milk substitute. I would not however use coconut cream.
Frozen Blueberries – We love to use frozen wild blueberries from our summer harvests. (Check out my blog post about how to freeze fresh blueberries for smoothies!)
Plain Greek Yogurt – You can also use a mix of yogurt and cottage cheese. You won’t taste the cheese!
Regular Peanut Butter – You can also use peanut butter powder to add even more protein and peanut butter flavor without increasing the fat and calories too much. Feel free to substitute any other nut butter if you cannot have peanut butter.
Flaxseed Meal – Optional.
Honey
Optional – Add a handful of spinach to the blender. It’s a great way to sneak in a serving of veggies that you can’t even taste – though you can see it, so if you have kids that won’t eat green things, only add a small amount.
Strawberries are a fun addition too – I like to just toss in whatever fresh fruit I have washed in the fridge!

The ingredients needed to make a blueberry, banana, and peanut butter smoothie - laid out and labeled. Milk, yogurt, bananas, peanut butter, and frozen berries.

How to Make a Peanut Butter Blueberry Banana Smoothie

Pour milk into the blender first to assist with blending, then add banana, blueberries, Greek yogurt, peanut butter, honey, and optional flaxseed into the blender.
Cover and blend until smooth and creamy.

Recipe Tip

Start your blender at its lowest setting so the liquid doesn’t splatter everywhere, then gradually increase the power/speed of the blades. Starting on low helps to better blend everything together.

Pour into glasses and serve. Top with a drizzle of warmed peanut butter and fresh berries if desired.

Make it a Smoothie Bowl

Reduce the amount of milk in the recipe to thicken the smoothie and turn it into a smoothie bowl. Top it with a drizzle of peanut butter, banana slices, peanuts, and whole blueberries. You could also sprinkle chia seeds and hemp seeds over the top.

Make it a Protein Smoothie

Add a scoop of protein powder to make it a protein smoothie. I like to use vanilla protein powder or unflavored protein powder. I also like to add two scoops of Vital Proteins unflavored Collagen Peptides to my smoothies.

Recipe Tip

If you use both frozen blueberries and frozen bananas the smoothie will be very difficult to blend, so I recommend letting the bananas soften a little before blending the smoothie.

Storage

Store leftovers in an airtight container in the refrigerator for 2-3 days or freeze. Stir before drinking as the contents may settle.
