Keto Peanut Butter Cup Chaffle Recipe

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.

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!
