Who doesn’t love the chocolate and peanut butter combination?

Well, maybe not EVERYONE loves it.

But, I bet you do or else you wouldn’t be reading this Creamy Keto Peanut Butter Cup Smoothie recipe post.

This smoothie has been a staple around here even before we went Keto and transformed it into it’s current low carb goodness.

If you are reading this post, you love shakes and this one was inspired by this Classic Keto Vanilla Shake. It’s amazing.


You can make this recipe vegan by using coconut cream instead of heavy cream but it won’t be as thick.

There is no exact amount if ice the you “have” to use. You can even skip if if you want.

It just provides the “iciness” that a lot of people look for in their chocolate shakes.

Feel free to exchange this with powdered peanut butter. Or you could exchange half for peanut flour. It will make your shake very thick though.

Of course you know that you should be using the “natural” kind of peanut butter in this recipe.

When I first started eating “Keto” I hated “natural” peanut butter. I hated that the oil separates out of it and I hated the mess that stirring a new jar creates.

But, I discovered a trick.

Before I open a new jar of natural peanut butter I always store it in the fridge UPSIDE DOWN for at least a couple of hours.

Feel free to use less of this ingredient if you don’t like dark chocolate.

I use this a lot in Keto Baking. This is the best deal that I’ve found.

It’s organic and lasts forever.

You could use cacao if you prefer. If you don’t know the difference (most people don’t), check out this post.

It’s pretty interesting and includes all of the nutrition facts, benefits of each.

  • Allulose or sweetener of choice to taste.

My family is fully Keto adapted and we only use 1-2 tbsp of sweetener. But, I was getting a lot of complaints about it not being sweet enough so I altered the recipe.

Feel free to add as much as you like. It won’t affect the carb count.

I really have been  loving Allulose lately. It’s a rare sugar and doesn’t upset my stomach at all.

If you don’t have powdered allulose on hand just put granulated allulose in the blender first and “blend” before you add anything else.

This will make it finer and help it melt into your shake better.

Or, you can use any sort of low carb sweetener that you like.

It also has a couple of candy recipes you might like included.

  • Salt– optional but great.

Sweet and salty…need I say more? If you are the type that shakes a little sea salt on top of your low carb ice cream or enjoys salted caramel, add it.

The salt really enhances the flavors in a way that no other ingredient does.

👩🏽‍🍳 How to make the Smoothie:

  • Put everything in the blender and whip it up until it’s smooth and fluffy.
  • Pour and enjoy.

📋Tips & FAQ’s:

Can I make this recipe ahead of time?

Nope. Smoothies are best served right away. It’ll separate and have a funky texture if you make it ahead of time.

My Keto Peanut Butter Cup Smoothie is not sweet enough!

Feel free to add as much low carb sweetener as you like.

Your cravings for super sweet treats will diminish as you continue eating low carb foods long term.

  1. Hi Mary! Yes, full fat milk will work just fine but is significantly higher in carbohydrates. Not a big deal if you aren’t doing a low carb diet and it will still taste fantastic. Cheers!

  2. Hi Lauren! I would start with a couple of tablespoons and go from there. Then you can make the shake as thick as you like. cheers!

  3. 5 stars
    This is now my favorite breakfast drink! I don’t drink coffee and this gives me the energy boost that makes my morning. Thanks!

  4. Hi Abi! Smoothies generally don’t “save” very well. They get funky quick. If you don’t want the entire recipe feel free to cut it in half. Cheers!

  5. If I’m the only one who will drink it, is there a recommended way I can save the remaining? I don’t want to drink the whole thing or waste it…

  6. 5 stars
    This smoothie is so yummy and hits the spot I love the flavour and can’t thank you enough for posting this!!

  7. Did a quick Pinterest search. Helped kick my ice cream craving tonight! Delicious!

  8. Hi Deborah! Yes, you can sub in whatever you like. Not sure how thick it will get but I bet it will still be delicious.

  9. Can I substitute half n half for the Heavy Whipping Cream? Heavy Whipping Cream tends to give me heartburn.

  10. Hey Lesa! Thanks so much for leaving a comment. Chocolate almond milk is my favorite! I’m glad you liked it. Cheers!

  11. This is amazing! I only had chocolate unsweetened Almond Milk so I used that. This is my new go to drink!

  12. OMG!!!! I am trying this tonight. I even have all the ingredients. I can’t wait until I get home. Thanks a bunch!!!
