Are Smoothies Keto?

You may know that smoothies aren’t keto, and most of them are made with fruits and have sugar added. That’s why you’ll need to try this keto chocolate milkshake that’s free from sugar and fruit, made from wholesome ingredients that are super nutritious.

This sugar-free smoothie is dairy-free and paleo, but you can swap the coconut milk to heavy cream without any problem. The smoothie becomes super silky and rick. It’s a keto smoothie that everyone loves.

You can adjust the sweetness, too. That’s the beauty of homemade keto recipes.

Low Carb Keto Smoothie with Chocolate and Peanut Butter

Is Peanut Butter Keto?

Peanut Butter is usually low in carbs and high in fat, therefore accepted in a keto diet. It’s best to choose a peanut butter that’s made from 100% peanuts without added sugar or palm oil.

The suggested serving size of two tablespoons of 100% natural peanut butter provides 4 grams of net carbs.

The best peanut butter for keto is the one that’s made entirely for peanuts and has no sugar added.

Reasons You’ll Love This Peanut Butter Smoothie

  • Tastes just like a peanut butter cup
  • Extra creamy and thick
  • Easy to make in just 2 minutes
  • Made with dairy-free and sugar-free ingredients

Keto Peanut Butter Smoothie Ingredients

To make this delicious keto smoothie recipe you need only a few nutrient-dense ingredients. I bet you have most of them in your pantry right now because all of them are essential low carb ingredients:

  • Cocoa Powder – Of course, choose unsweetened cocoa powder. Opt for a high-quality brand to get in all those antioxidants and maximum taste.
  • Peanut Butter – In fact, you can use any nut butter. Just make sure to choose a creamy one that has no sugar added. My other favorite nut butter to add to this smoothie are cashew butter (slightly higher in carbs but heavenly delicious), almond butter, or macadamia nut butter.
  • Coconut Milk – Use the canned one that’s higher in fat and extra creamy. Coconut is smooth and thick and adds a little bit of sweetness to this keto peanut butter smoothie.
  • Sweetener – My favorite Sweetener is Powdered Erythritol because, to me, it doesn’t have any after taste and it’s low in carbs. Feel free to use Monk Fruit or a few Stevia Drops. Liquid stevia dissolves faster than erythritol making it a better choice in this keto smoothie recipe. Just choose your favorite sweetener and adjust the sweetener to your preference.
  • Ice Cubes

How to Make a Sugar-Free Peanut Butter Smoothie

Smoothies are undoubtedly the easiest recipe you can make:

  1. In a blender, add all the ingredients.
  2. Pulse until smooth and creamy. Taste and adjust the sweetness.
  3. Serve with a dollop of whipped cream!

Just blend all the ingredients, and in 30 seconds you have a delicious keto drink to slurp on.

After all this “hard work” and all that blending, it’s time to adjust the sweetness.

I’m a weirdo when it comes to sweetened drinks because I love my drink to taste at least sweet as possible. So, if you’re on the other side and want your low carb smoothie to be extra sweet add more sweetener. Just taste test it.

These are the main ingredients needed in this keto smoothie. In the recipe card below, you can find all the measurements plus other things to add to make this chocolate peanut butter to the next level.

Keto Smoothie Toppings

Toppings are vital for a perfect chocolate peanut butter smoothie. So don’t forget to add your favorites.

Add a dollop of homemade whipped cream, drizzle a sugar-free chocolate syrup, keto caramel, more peanut butter, chopped peanuts, and even chocolate chunks sound divine to me.

Breakfast Keto Smoothie or Snack?

To be honest, I love my smoothies anytime. Usually, I have a smoothie first thing in the morning because I am not a fan of heavy breakfast meals. My keto green detox smoothie is perfect for a quick morning energy boost too.

This delightful chocolate smoothie is perfect as a breakfast treat or as a snack on hot summer days.

    This was delicious! I didn’t have vanilla extract so ì had to leave it out but it was still so good. Might add a little extra cocoa powder next time because I’m such a chocolate lover.

    1. It’s great to hear that you enjoyed this keto smoothie! You can definitely add a little extra cocoa powder next time to enhance the chocolate flavor. Vanilla extract is not always necessary in recipes, so leaving it out should not have a major impact on the overall taste. Happy cooking!

  2. 4 stars
    This was excellent. I only used a little stevia but it didnt need much. The bonus is that its got plenty of fat in it for those days where I eat leaner than I would like
