  • Peanut butter – as mentioned above, make sure you use natural peanut butter, no added sugar, no added oil. It’s full of healthy fat and contains almost no carbs.
  • Sugar-free crystal sweetener – I love to use Erythritol or Monk fruit blend, but xylitol will work as well. Learn more about keto sweeteners.
  • Unsweetened cocoa powder – this adds a delicious chocolate flavor for the best chocolate smoothie.
  • Cream – heavy cream or canned coconut cream for a dairy-free alternative. Learn why cream is a good keto-friendly dairy product.
  • Unsweetened almond milk 
  • Ice cubes – play with the amount of ice and change the texture! For an icier, frothier low-carb smoothie recipe, add a few more ice cubes!

Expert Tip: Varying Taste

This keto smoothie is a very versatile recipe that makes it tops the list of my best keto smoothie recipes.

You can transform it by adding the following ingredients:

  • Raspberries or Strawberries
  • Spinach or Kale – full of nutrients, vitamins, antioxidants, and minerals.
  • Almond Butter – instead of peanut butter. You can also use other nut butter.
  • MCT Oil – while it barely changes the flavor, it boosts the healthy fats in your smoothie.
  • Chia Seeds – to add thickness
  • Vanilla extract or almond extract.
  • Turmeric – for a touch of spices.
  • Fresh Mint, Cucumber, or Celery – for a fresh taste.

Storage Instructions

Keto Smoothies, like regular smoothies, are tricky to store as the various phases in the liquid tend to separate.

However, you can store them in a container with a lid in the refrigerator. Make sure to blend it again for a few seconds before serving to get its full creamy texture back!

Frequently Asked Questions

Let me answer the common questions about this keto smoothie.

Why can’t I use dairy milk in a keto smoothie?

Of all dairy products, milk is one of the highest in carbs.
Milk is therefore not keto-friendly since it contains a large amount of lactose, one of the disaccharides that increase blood sugar levels quickly.

Are You Allowed Smoothies On Keto?

Classic takeaway smoothies are most of the time not keto-friendly. However, keto smoothie recipes like this one are perfectly fine to have daily.

Can I Add Bananas To My Keto Smoothie?

Bananas are not recommended on a keto diet because they are quite high in carbs.
As a result, a very small amount of banana contains as many carbs as many raspberries or strawberries.

Can I Use Another Nut Milk?

You can use any plant based milk such as coconut milk, cashew milk, or almond milk.

Can I Take A Peanut Butter Smoothie As A Protein Shake?

Absolutely! Many Keto-friendly smoothies can be used as protein shakes. Just make sure to include enough good protein sources!
One way to add some healthy, keto-friendly vegetarian proteins is to add a scoop of low-carb protein powder. Most of them would not alter the total carbs but would boost your proteins!

Is Peanut Butter Keto-Friendly?

Yes, you can have peanut butter on a keto diet. Obviously, it has to be pure peanut butter made of 100% peanuts with no added sugar and no added oil.
In fact, vegetable oils are not keto-friendly, and many brands add oils or sugar to their products.
So make sure to check the ingredient list and look for peanuts only or peanuts and salt.
So, is this chocolate peanut butter smoothie keto? Yes, it very much is! Use it to top up your macros!

  1. 5 stars
    YUMMMMMYYY!!! This satisfies my chocolate craving while on Keto but feels and tastes like a cheat. I only added chia seeds as I do to almost all of my smoothies. 100/10!

  2. 5 stars
    I recently had gum surgery and have to be only on liquids for next few days. I try to follow keto as well and found this recipe. It was so easy to make, I had all the ingredients and it was delicious. I will be making this again and in future this will be a perfect breakfast as well. thank you

  3. 5 stars
    This was absolutely delicious. I unfortunately didn’t have unsweetened almond milk so I used soy milk, and I didn’t have natural peanut butter so my smoothies had about 6 net carbs per serving which isn’t bad at all. I also only used 2 tablespoons of stevia since I know how powerful it can be in small amounts. But all in all this was delish. My wife doesn’t like peanut butter but she loved this

  4. 5 stars
    Super yummy! Love peanut butter and chocolate. Might add a splash of banana extract next time (Olive Nation extracts rock!) for a Chunky Monkey flavor combo. Thanks for an awesome smoothie recipe!

  5. 5 stars
    Delicious and so very simple. I added 2 eggs to add protein and body (many don’t eat raw eggs I know but I have in shakes for yrs).

  6. 5 stars
    Delicious and so very simple. I added 2 eggs to add protein and body (many don’t eat raw eggs I know but I have in shakes for yrs).
    My only point here would be to clarify it contains heavy cream.

      So easy to make!
      So delicious!
      Felt like i was having a “milkshake” for the first time in over a year.
      Will definitely make this again!

    Delicious and so very simple. I added 2 eggs to add protein and body (many don’t eat raw eggs I know but I have in shakes for yrs).
    My only point here would be to clarify this is not. Dairy free as it contains heavy cream.

  8. 5 stars
    This smoothie recipe is absolutely amazing! I made it exactly as directed, and let me tell you, none went to waste. I am a huge peanut butter fan, but doing a low carb diet restricts how much I can have, so when I ran across this recipe I was so excited to try it! I will even admit that I drank both servings tonight. It was definitely worth it, though, I have no regrets. 😊I see a lot more of this smoothie in my future.

  9. 5 stars
    This turned out so good! I added kefir and baby spinach, even my picky toddlers loved it! Thanks for the great recipe.

  10. 5 stars
    Okay Ya’ll ,this smoothie is so delicious. I only made half and its a good thing cause I would have consummed both servings. It sweet, creamy and tastes so good. I squirted a dollop of whipped cream on top and I was in milkshake heaven.

  11. 5 stars
    Not on keto. but. pregnant and have gestational diabetes. I was craving chocolate and peanut butter, (I had to add my prenatal protein powder instead of the sweetener, mainly t o get more nutrition and make a meal of it) but this was good, curbed my cravings, extremely satisfying and didn’t spike my sugars 🙂

    • 5 stars
      I used Peanut butter powder and Half-and-half to cut some of the calories out. It was very delicious as one milkshake. I also added some frozen riced cauliflower to make it a little thicker since I took out a bit of fat.

  12. 5 stars
    Oh I love this drink so much! It filled me up and definitely supplemented my cravings. I doubled the amount because I’m sharing with my toddler. It still turned out amazing! It has the correct portion of the ingredients, just the right amount. The heavy cream made it frothy on top which is awesome! I really enjoy this recipe and will absolutely add in my collection list of best keto smoothies! Thank you.
    I would love to connect with you.

  13. 5 stars
    Second time I’ve made this one and I really like it. This time I just did the entire 2 serving recipe and drank it as one large one. I could get used to this smoothie, though I’d be curious to try it with almond butter as another poster said they did. Thanks for putting it together!

    • 5 stars
      I loved the simplicity of this recipe. I used sunflower butter instead of peanut butter (tastes exactly the same!), I added 2 tbls of organic super seeds (added fiber) and used frozen avocados (added fat) instead of ice. So yummy and smooth. I will adding this to my smoothie rotation.

  14. I would love to know where you get natural peanut butter with less than 180 calories per 2 tablespoons and how this recipe only has 172 calories for the whole thing when heavy cream has well over 150 calories by itself for 1/2 cup. I created the exact same recipe in my fitness pal and got total of 427 calories. everything else (carbs, fat, etc. was relatively the same.
