Ingredients needed for a chocolate peanut butter smoothie.

Is peanut butter keto?

Peanut butter can be keto as long as you choose a brand that has no added sugars and you limit the quantity that you eat.

Peanut butter is a legume so will naturally be higher in carbs and some on the ketogenic diet choose to avoid it. However, as long as you can tolerate peanut butter and you only use the minimum for flavor then it can be considered to be keto.

This low carb smoothie recipe only requires 1 tablespoon of unsweetened natural peanut butter = 2.5 g net carbs for the entire recipe. The creamy homemade cheesecake gets the lovely nutty taste of the peanut butter, but with minimal carbs.

Can I add fruit to my low carb smoothie?

This recipe is absolutely fantastic as is. However, if you want to add a bit more fiber to this smoothie, you can add a small handful of low carb fruit. The best low sugar options are berries.

You can simply change this into a low carb strawberry smoothie by adding some fresh or frozen strawberries. Or, opt to add raspberries, blueberries, or blackberries instead.

Just keep in mind, that this will change the nutritional info and the carb count. You’ll want to be conservative with the amount of fruit you add if you want to keep this a low carb smoothie recipe!

Can I make this a green smoothie?

Craving a bit of green? Turn this into a keto green smoothie by adding a handful of fresh or frozen spinach or kale. Green smoothies can be a great way to add nutrients to your smoothie, but keep in mind that it also adds carbs.

While the carb count for spinach and kale is fairly low, it’s something to keep in mind!

Is this a keto smoothie?

At 5.7 net carbs, and 12 grams of fat, this peanut butter smoothie can be considered a low carb keto smoothie!

To keep this keto-friendly, make sure to use a full fat yoghurt that has the fewest carbs possible.


Now, let’s get into how to make this low carb smoothie! Making a chocolate peanut butter smoothie is a simple process, but you will need a blender or food processor.

Start by adding all your ingredients to your blender.

Add all your ingredients to a blender to make your smoothie.

Then blend your smoothie ingredients until all the ice has been crushed. Depending on your blender this could take 20-60 seconds.

Blend your smoothie until the ice has been crushed.

Finally, pour your smoothie into a cup and enjoy! If you would like top your smoothie with a bit of unsweetened whipped cream.

Hint: For a thicker low carb smoothie add more ice. I like to add the ice to my blender last so that it stays colder for longer and gives that lovely crunchy slushy feel.


Do you really want to make this low carb chocolate peanut butter smoothie, but are looking for dairy free or nut-free alternatives?

We’ve got you covered. Check out our recommended substitutions below.

  • Yogurt – If you are looking for a diary free option use full fat unsweetened coconut cream instead of yogurt.
  • Almond milk – Coconut milk or regular milk can be used in place of almond milk in this low carb smoothie. Be aware if you decide to use a different type of milk, it will affect the carb count considerably. Also check for any added sugars. Oat milk and cashew milk often have the highest carb value and the smoothie will no longer be keto friendly.
  • Peanut butter – This smoothie will work with any nut or seed butter, so pick your favorite. Just make sure to choose a low carb option that’s sugar free.

Keep in mind that changes made to the ingredients will change the nutritional facts below.


Do you love the idea of chocolate peanut butter smoothies, but think it’s missing something? Or maybe you’ve tried and want to explore more options? Give these variations a try!

  • Vanilla – add a splash of vanilla extract for extra flavor.
  • Deluxe – top your smoothie with sugar free whipped cream, keto caramel sauce, and crushed peanuts!
  • Make it hot – believe it or not, this peanut butter smoothie could make an excellent hot chocolate. Warm it up after blending for an easy and delicous hot cocoa.

Pour your smoothie into a cup and enjoy!


You are going to need a blender to make this low carb smoothie recipe. The good news is you can make this smoothie with any sized blender.

I used an individual-sized blender to make this smoothie, but you can also mix it up in a full-sized blender or with a stick blender. Just use what you have on hand.


There really isn’t a good way to store this smoothie if you can’t drink it all. You can place it in the refrigerator to keep it cool and drinkable, but the ice is going to melt. If one smoothie is too much for you, feel free to cut the recipe in half.

These ingredients don’t stand up well to freezing. Your smoothie will turn into a popsicle in the freezer, but maybe that’s not a bad thing.

Top tip

The ingredients used in this low carb keto smoothie don’t have a lot of natural sweetness to them. That is why we added sweetener to the recipe.

Taste your smoothie to make sure you have added enough sweetener to match your tastebuds. You can always add a little bit more sweetener to your smoothie and mix it up again.

    What do you suggest to make it higher in protein?

    1. 5 stars
      If you want this to be higher protein you could add some unsweetened protein powder, whey protein powder, collagen powder, or chia seeds.
