Why You Will Love This Cookie Protein Shake

The main reason why I personally love this protein shake is course the flavor and indulgence.

This is the main reason why I think you will love it. It’s completely guilt-free.

Other reasons include:

  1. Guilt-Free Indulgence: With the rich flavors of cocoa and peanut butter, this smoothie tastes like a decadent dessert but is made with health-conscious ingredients, allowing for a guilt-free indulgence.
  2. High in Protein: Thanks to the addition of protein powder and peanut butter, this shake is a fantastic source of protein. A serving of this shake contains 28g of protein.
  3. Energy Boosting: The combination of complex carbohydrates from oats natural sugars from bananas and optional honey or maple syrup provides a sustained energy release.
  4. Rich and Creamy Texture: The use of banana and yogurt gives the shake a creamy, smooth consistency that’s both satisfying and comforting, much like a classic milkshake.
  5. Nutrient-Rich: Packed with vitamins, minerals, and fiber, this shake is not only delicious but also incredibly nutritious, offering a well-rounded snack or meal replacement.
  6. Versatile and Customizable: Easily adaptable, you can switch up the ingredients according to dietary needs or flavor preferences.
  7. Quick and Convenient: It’s easy and quick to prepare, requiring just a few minutes and a blender.

Smoothie Variations And Recipe Notes

You can easily substitute some ingredients, or even add additional ingredients should you want to.

Below I am going to leave some options for you, but feel free to experiment on your own too:

  • Change The Protein Powder Flavor: You can use any flavor you like, peanut butter, chocolate, and even cookie dough protein powder!
  • Nut-Free: For a nut-free shake, swap the peanut butter for sun butter, and the almond milk for oat milk.
  • More Cookie-Flavor: For a more indulgent shake, crush 1 Oreo cookie in the blender before blending for a stronger cookie flavor!
  • Deeper Chocolate Flavor: Use 2 tablespoons instead of 1 of cocoa powder for a richer chocolate flavor. 
  • Boost Of Caffeine: Add a teaspoon of espresso powder for a caffeine boost.


Blender Type Suitability
Nutribullet 600
Vitamix Blender Propel 510
BlendJet 4000mAh x
Ninja Blender BL610
Oster 6640 Blender
Hamilton Beach 58148A Blender
AMZChef Blender 1800 W
Wamife Blender

Out of the 8 blenders and models I own and tested this recipe on, only the BlendJet 4000mAh didn’t do the best job.

For that reason, I suggest that you avoid making this protein shake using this blender.

Protein Cookie Shake FAQs:

Can I Add Fresh Fruit Instead of Frozen?

Absolutely! Using fresh fruit instead of frozen can change the texture slightly, making it less thick. If you prefer the thicker consistency typically provided by frozen fruit, you might want to add a few ice cubes to achieve a similar texture.

Is This Shake Suitable For Children?

Yes, this shake can be suitable for children, especially as a tasty way to get more protein into their diet. However, be mindful of any allergies and the added protein needs for kids, which are usually lower than adults.

How Do I Store Leftover Protein Shake?

Leftover protein shake can be stored in the refrigerator for up to 24 hours. Make sure to use a sealed container or a bottle with a tight-fitting lid. Give it a good shake or stir before drinking, as the ingredients may separate when stored in the fridge
