Ingredients

  • 1 ⅓ cup (200g) frozen banana chunks (ripe is best)

  • 1 scoop (31g) lightly-flavored vanilla protein powder

I love this lightly-flavored vanilla protein powder for creamy protein shakes and smoothies. It is unsweetened, so you can add your favorite sweetener (or not), and its flavor is very subtle and does not outshine the flavor of the other ingredients in your shake.

Read more about why I love it here: The Best Protein Powder for Shakes and Smoothies. It is my go to protein powder for protein shakes and protein ice cream. Try it!

Equipment Needed

  • kitchen scale - I recommend using a kitchen scale for better accuracy and easier clean up.
  • high-speed blender - I highly recommend this personal smoothie blender for all protein shake and smoothies. Read why here: the best smoothie blender on a budget.

How to

1. Place frozen banana chunks, milk, peanut butter, protein powder, and a pinch of salt into the blender.

2. Blend 30-60 seconds, until smooth and creamy.

3. Pour into your favorite glass or to-go cup, and enjoy!

Ingredient Substitutions

Milk: Try a plant-based milk with a different flavor, like coconut milk or oat milk.

Peanut Butter: Experiment with almond butter, cashew butter, or even sunflower seed butter for unique flavors.

Protein Powder: For whey or whey/casein substitutions, chocolate whey or cinnamon flavored whey/casein protein powder are great options for this recipe. For plant-based protein powder options, I'd go with a chocolate protein powder (pea protein blend) or peanut butter powder.

Recipe Variations

Make a chocolate peanut butter banana smoothie by adding a tablespoon of cocoa powder or sugar free chocolate chips (or by using chocolate protein powder).

Turn this into protein ice cream by putting the blended shake into an ice cream maker.

Add ground flax seeds for added dietary fiber and a superfood boost!

Storage Info

This peanut butter banana shake will stay well for 24 hours after blending if kept in the refrigerator. I like to keep my shakes in these thermal tumblers in the fridge and for on the go.

FAQ

Is this suitable for weight loss?

Yes, it can be part of a weight loss plan with its balanced nutrition and no added sugar. Since this shake is higher in calories than some others, you might want to use this as a meal replacement or have ½ recipe as a high protein snack.

Can I make this without protein powder?

Certainly, but the protein powder adds an extra nutritional punch. It also helps with satiety, keeping you fuller longer.

Can I use fresh bananas instead of frozen?

Yes, but frozen bananas contribute to the creamy texture. Add a few ice cubes if using fresh bananas to keep the shake frosty.

How can I adjust the thickness?

Add more milk for a thinner consistency.

Is this peanut butter shake kid-friendly?

Absolutely! Kids love the creamy texture, and you can sneak in extra nutrition without them noticing.

Is it suitable as a meal replacement?

Yes, with its balanced nutritional profile, it can serve as a healthy and satisfying meal replacement.
