When it comes for keto breakfasts that aren’t eggs, I’m alternating between keto oatmeal, keto cereal, and this creamy keto breakfast smoothie.

I’ve got a few keto smoothie recipes on here, but none with my all time favorite food- Peanut butter!

There is something special about peanut butter, especially when added with chocolate! This keto chocolate peanut butter smoothie ticks all the boxes. It’s thick and creamy, and tastes like dessert for breakfast! 

Unlike traditional smoothies, this low carb peanut butter smoothie is made dairy free and no fruit, but you’d never tell!

How to make a keto peanut butter smoothie

The Ingredients

  • Milk of choice– I used unsweetened almond milk, but you can use any milk you like (I also enjoy coconut milk). 
  • Peanut Butter- Smooth and drippy peanut butter is preferred, as it blends beautifully into the smoothie. Be sure you use a sugar free peanut butter. 
  • Cocoa Powder– Unsweetened cocoa powder. For an ultra rich flavor, use dark or black cocoa powder. 
  • Avocado– Avocado adds extra creaminess and thickens the smoothie, without using fruit. You can omit this, but this helps keep you even more satisfied. 
  • Sweetener of choice– Either keto maple syrup, a few drops of liquid stevia, or a tablespoon of erythritol or monk fruit sweetener. You can adjust the sweetness level to your preference. 
  • Powdered Peanut Butter– Optional, but highly recommended. Keto powdered peanut butter gives this smoothie a bigger hit of peanut butter flavor, without adding extra fat or calories. Powdered peanut butter is oftened referred to as peanut flour. 
  • Ice– Optional, but recommended if you want a super thick smoothie.

The Instructions

In a high speed blender or food processor, add all your ingredients, except for the ice. Blend until completely combined. Enjoy as it is, or for a thicker smoothie, add some ice. Blend once more and serve in a glass.

Can I add protein powder? 

For an extra protein boost, add some keto protein powder to it. I recommend either a keto chocolate protein powder or a keto vanilla protein powder. Be sure to check the carbs of the protein powder you use, to ensure there is no added sugar to it. 

Can I prepare this smoothie in advance?

As this keto smoothie is made without fruit, it doesn’t separate when blended, so feel free to prepare smoothies in advance and enjoy at a later time.

  • To store: Place smoothie in small glass jars or glass bottles, and enjoy within a week. 

Keto Smoothie Tips

  • Ensure you use a good quality high-speed blender to ensure all the ingredients are fully incorporated. Alternatively, a food processor works just as well.
  • Any milk will work, but I prefer canned coconut milk, as it adds a creamier flavor and richness.
  • The recommended amount of peanut butter is just that- a recommendation. Please don’t hesitate to increase it, as it will only make it taste better!
  • To reduce the fats or make this smoothie without avocado, you can omit it. To compensate, simply reduce the amount of milk and if it’s not thick enough, add a handful of ice.
  • You can omit the sweeteners if you add protein powder which is pre-sweetened.
  • If keeping this smoothie peanut-free, omitting the powdered peanut butter is fine, especially if you sub it with almond flour. If you use neither, just start with the minimal amount of liquid and add ice as needed.
  • Using ice is optional, and not necessary. Provided you start with the minimum amount of milk, you can still ensure the texture is creamy and thick without it.

A healthy and filling keto peanut butter smoothie recipe which tastes like dessert for breakfast! Loaded with peanut butter, peanut butter powder, and avocado, this thick and creamy low carb peanut butter smoothie keeps you satisfied all morning!  
Servings: 1 Smoothie
Prep: 1 minute
Total: 1 minute



  • In a high-speed blender or food processor, add all your ingredients, except the ice, and blend well.
  • If the smoothie is too thick, add enough milk to reach your desired consistency. If the smoothie is too thin, add some extra ice or powdered peanut butter. 
  • Pour into a glass and enjoy!


* My liquid stevia is 5 drops per serving. Adjust to taste.
** Only add ice if you want your smoothie thicker. For a thinner consistency, add extra ice.
Keto Chocolate Peanut Butter Smoothie should be enjoyed immediately, or within 3 hours of making it. I keep it in a cooler bottle to ensure it is consistently cold. 
If you pre-make it to enjoy it later, give it a good stir before drinking, as it may have separated.

    I was looking for something different for breakfast this morning when I saw this appetizing picture of your smoothie and just had to try it. The only thing I didn’t have was the dry Peanut Butter and I used 1tbls of Erythritol sugar. It came out Luscious!! I really enjoyed it. In fact, I just finished it and wanted to share my enjoyment with the recipe. I did add 1tbls of whipped cream on top but that really just adds to the beauty of the drink. LOL
    Thanks Arman!

    I take this super easy shake as a breakfast meal! Super satisfying and delicious!! Well done and thank you 👏🏻

  3. Oof, I NEED this smoothie now. I haven’t had a smoothie with avocado since visiting Vietnam two years ago–definitely have to try it out one day, but I might use coconut cream instead just to see what the result would be!

    1. Hi there, omit the avocado, decrease the liquid and add a little ice if needed to be thicker. Alternatively, add an extra tablespoon or two of nut/seed butter 🙂

  4. Hey Arman – here’s a tip: buy avocados on sale, mash them up with a fork and mix in a bit of lime juice, form into serving size patties on parchment paper, freeze, then store the patties in a freezer bag. When you make your smoothie, throw one in to help add thickness and healthy fat! 🙂
