Chaffles are super popular right now in the keto community, and for good reason! They are so easy to make and they taste amazing! We started with our Best Oreo Keto Chaffles and they were so good that they inspired us to branch out and see what other kinds of dessert chaffles we could come up with!

It didn’t take much time at all for us to come up with this yummy keto peanut butter cup chaffle! Peanut butter cups are one of our favorite treats and they are probably one of yours too. There is really nothing better than sweet peanut butter and chocolate!

What Is A Chaffle? 

The chaffle is everyones favorite new keto invention as of late. The chaffle started popping up in all of the keto Facebook groups I am in, and everyone immediately began to come up with a bunch of amazingly creative ways to customize the chaffle.

There are really two kinds of chaffles: there are savory chaffles, and there are dessert chaffles. Savory chaffles are almost always made with an egg and cheese, and sometimes other savory ingredients like bacon bits.

Savory chaffles are typically used as a bread replacement or as a bun, but there is really no limit to what you can use them for! They are super versatile and adaptable.

Dessert chaffles are usually not made with cheese, but they can be. There are a million different ways that you can make and enjoy a dessert chaffle. Since we can’t talk about all of them here, we’ll just point out that most dessert chaffles are made with an egg, heavy cream, baking powder, sweetener, and sometimes vanilla extract.

There are a ton of amazing dessert chaffles out there but this keto peanut butter cup chaffle is one of our favorites!

Can You Make Chaffles Ahead and Freeze?

For sure! Chaffles freeze really well and they make for an awesome on-the-go snack. There are two ways you can freeze chaffles:

The first way is to individually wrap them and freeze them that way. This is simple to do and it prevents your chaffles from freezing together and being stuck together until they both thaw out. This isn’t a problem if you want two chaffles, but if you only want one this can be an annoying problem.

Another way that you can store your chaffles in the freezer is by flash freezing them on a baking sheet. Once they are frozen, you can place them all into a ziplock bag without worrying about them feeling together.

No matter what option you choose, you can rest assured that your chaffles will freeze well and taste great once they are defrosted. I would recommend that you reheat your chaffle in a toaster rather than a microwave. This will ensure that your chaffle gets crispy and not soggy.

Best Mini Waffle Maker To Use:

In our opinion, the Mini Dash waffle maker is one of the best mini waffle makers on the market. It is so easy to use, it is a breeze to clean after each use, and it makes the perfect sized chaffle each time! They come in many different colors and you can’t beat $10!

Another plus in using this mini waffle maker is that it is so easy to store. If you leave it on your counter it takes up almost no space. If you store it in a cabinet it will be almost unnoticeable. The mini Dash waffle maker is definitely worth checking out.

family waffle maker product

If you have a big family (or just really love chaffles like I do), you may also want to consider getting a waffle maker that will cook multiple miniature waffles at once.

The Burgess Brothers ChurWaffle Maker is very popular in the keto community, and it can make four waffles at a time! The mini waffle makers are great, but if you are making keto strawberry shortcake chaffles for the whole family, it could take a while making one at a time.

No matter what you choose, your chaffles will turn out great, and you will love this amazing new invention called the chaffle!

Ingredients Needed For Peanut Butter Cup Chaffle

This keto peanut butter cup chaffle is so easy to make, and that’s mostly because of the ingredients. There is a really good chance that you already have everything you need to make this chaffle.

For this peanut butter cup chaffle, we used an egg, some vanilla, sweetener, heavy cream, cocoa powder, coconut flour, cake batter flavoring (this one), and baking powder. If you have these ingredients (or most of them; cake batter flavoring is really good but not necessary), you are good to go!

Cleaning your mini Dash waffle maker is so easy already, but if you want to make it even easier, consider these silicon basting brushes. They make cleaning the nooks of a waffle maker so much easier!

Peanut Butter Cup Chaffle Filling

For the filling of this yummy keto peanut butter cup chaffle, we used heavy cream, peanut butter, and Lakanto powdered sweetener. It really is as easy as blending together some ingredients.

Because of the peanut butter, your heavy cream probably won’t form any stiff peaks, and thats okay. What you want to end up with is more of a whipped peanut butter rather than a whipped cream peanut butter, if that makes sense.

To make this peanut butter cup chaffle filling, just blend all of the ingredients together until you reach your desired consistency. It shouldn’t take more than 3 or 4 minutes to completely whip these ingredients together.

Also, there are many peanut butters out there that have a of sugar in them. We suggest stick to the Natural Peanut Butter where the macros are significantly different than others.

Variations To This Sweet Chaffle

With all of our recipes, and especially with all of our chaffle recipes, there is a ton of wiggle room. You can change this recipe up to suit your tastebuds and it will still turn out great.

Some of the things you can do to change this recipe are:

  • Swap coconut flour for almond flour. This won’t be a perfect 1:1 swap though, so be careful not to add too much or too little almond flour. As a rule of thumb, generally 1 part coconut flour will be equal to 3 parts almond flour.
  • Use a different sweetener. We recommend Lakanto’s powdered monkfruit for this recipe, but it is definitely not the only sweetener you can use. If you prefer stevia, use stevia. If you refer erythritol, use erythritol.  We like Lakantos Monkfruit just because to us, it’s the best tasting, meaning there’s no aftertaste and taste most like regular sugar. If you want to give it a try, use our code “BUTTERTOGETHER” for 20% off your entire purchase HERE.
  • If you love peanut butter, you can consider adding Peanut Butter Powder to the batter. Or, even use it for the filling and whip it up with some whipped cream. You can try Lakanto’s No Sugar Added Peanut Butter Powder, sweetened with Monkfruit HERE.
  • Feel free to add a teaspoon of cream cheese to the batter to make it thicker and richer!

  • Patti Weyers

    This looks good!! I don’t have the cake batter flavoring, it’s ok to just omit that?


  • Sherri

    Help, amount of cake batter extract if choosing to use? Can’t wait for your reply, as I’m excited to make this.TIA

  • Barbara Burditt

    I made a large recipe of these and froze them! Yay they are so yummy! Thank you! Thank you! Thank you!

  • Marilyn WarrenMOMG

    OMG also mode this today, I love this, made one tomorrow too. 5/5

  • April

    Have you tried it with almond flour? I’m becoming a not so big fan of. Coconut flour. Also if you don’t want it to eggy could you just use the egg white and not the yoke?

    • Kasey

      Absolutely! Use 1 tbsp Almond Flour instead. Yes, using just the egg white will definitely reduce the egg taste. Enjoy!

  • Brooke Heath

    This recipe has changed my life. I made it for breakfast this morning (because who doesn’t love dessert for breakfast?!) and found it to be quick, super easy, and decadently delicious! I didn’t have cake batter extract on hand so I doubled the vanilla (I always use Mexican vanilla because it’s so much better than the vanilla you can buy in the US) and you totally didn’t miss out on the cake batter flavor. The peanut butter filling was so creamy and delicious. I substituted PB Fit because I had it in the pantry instead of natural peanut butter and it worked out great. I will definitely be making this recipe again and again!

    • Kasey

      Thank you so much for the great feedback! I’m glad you loved it. 🙂

    • Debbie

      Using the pbfit did you just mix the powder with the cream or did you add water as well?

    • Sharon

      Thank you so much for this recipe! I had just about given up on finding a dessert recipe I enjoyed. I made this recipe this morning and it was amazing! There was no after taste and everything was perfectly sweetened. I immediately shared this recipe with my sister! Thank you!

    • melissa

      @Debbie,I used pbfit as well to cut the calories, I used water to make peanut butter and then added the cream, only needed 2 tb of powder. calories much better, the calories are upwards of 500 with peanut butter which has almost 200 cal per 2tb in itself

  • Shonda

    I’m seeing 2:1 and 1:1 lankanto. Which one do I get?
    Thank you!!

    • Kasey

      2:1 Lakanto Powdered Sweetener 🙂 Be sure to use BUTTERTOGETHERK for 20% off the sweetener on the Lakanto website!

  • Amber White

    Do you have measurements for the peanut butter filling?

    • Kasey

      Yes, they are in the recipe card at the bottom of the post:
      3 tbsp All natural Peanut Butter
      2 tsp Lakanto Powdered Sweetener
      2 tbsp Heavy Cream

  • Ida

    Are both chaffles and the filling one serving?

    • Kasey

      Yes, the serving size includes both chaffles and the filling! Enjoy!

  • Pam

    Amazingly delicious!!!

  • Tina

    This was so good! I didn’t see to replace the cake batter with vanilla so I just omitted it. I did egg whites only because the first batch was too eggy for us.

    Also added about a handful of finely chopped dark chocolate that I had to the chaffels.

    So so good. Definitely a keeper!

  • Tanchinjim

    Plugged recipe into MFP app with standard ingredients (i.e. unsweetened PB) and am getting very different calories / macros for 1 serving with 2 chaffles + filling:

    Calories = 534
    Fat = 45.7g
    Protein = 19.7g
    Carbs = 14.6g
    Fiber = 7g
    Net Carbs = 7.6g

    Not sure if I’m misinterpreting something but 1 large egg (70 cal), 3 tbsp PB (270 cal) and 3 tbsp heavy cream (150 cal) alone is 490 calories.

    • Misty W

      @Tanchinjim, I just made them and had the exact nutritional info. I could only eat half. I was very disappointed that it was double calories and carbs. Super tasty though.

    • melissa

      I agree on calories, too high with 3tb of pb and 3 tb of cream. I substituted pbfit for peanut butter and used 2 tb made with water and then added 1 tb of cream. it came out good.also next time I might just use egg white , trying to keep it under 300 cals in total

  • Tessa

    Good recipe, tasty. Filling makes a LOT.

  • Jacqueline

    Tried this absolutely love it, couldn’t b any easier,, already made it twice so so good thank you

  • Amy

    Can you use powdered swerve? If so is it the same measurement. Thanks!

  • Ramona

    I just bought a mini waffle and have only just begun making “Chaffles”. I’ve tried a few that were okay, but many are too ‘eggy’. I just finished eating my Peanut Butter Cup Chaffle and I AM IN HEAVEN!!!

  • Krista

    OMG these were delicious!! I didnt make the cream filling, just the chaffles and were excellent. I didn’t think they were eggs, but spongy

  • Kimm

    These are slap yo momma fantastic!!!! I felt like I was eating a piece of cake.
    I HIGHLY HIGHLY recommend!!!!!

  • Carrie

    Calorie bomb, but yummy! Have to pay attention to the nutrition info, though. I saw on a macro counter where someone listed this but had it as TWO for the serving size when it says YIELDS 2, but serving size is ONE. The peanut butter center is AMAZING alone. I could get in trouble with that part!! LOL

  • Fadiylah Shabazz

    I made these but I didn’t have any cocoa so I used what I had. I used the Chocolate Slim Fast Meal Replacement instead and they came out beautifully. My husband thought I was making brownies. Using the Slim Fast replacement also took the place of the extra flavorings and sweetener. I don’t usually use Splenda but again, it was what I had to sweeten the peanut butter filling and it was so delicious I was tapping my foot while eating it. I took it for lunch with a few pieces of Turkey bacon to balance the sweet with a little salty. I’m making more tonight but I making cream cheese filling instead.

    • Kasey

      Thanks for the feedback and ideas. We are so happy you liked it!


    Wow, going Keto just got really exciting! I made a large batch to enjoy for days. Didn’t have cake batter flavoring, so I just used extra vanilla, but now ordering it. Thank you for the wonderful recipe!

  • Maureen Paige

    So good! I love anything chocolate and peanut butter, so this hit the spot!
    Thank you!

  • Kim

    Thank you for the recipe! Just made this for my husband and myself. It was delicious!
