Keto Nutter Butters | The Best Keto Peanut Butter Cookies

These keto nutter butters combine two chewy and slightly crispy peanut butter cookies with a delightfully smooth peanut butter filling in the middle. And if you love peanut butter, these keto peanut butter cookie sandwiches will become your new best friend. Plus, they're just incredibly quick and easy to whip up too!

THE BEST KETO PEANUT BUTTER COOKIES

Nutter butters have to be one of my all-time favorite cookies. I mean, what's better than peanut butter on top of peanut butter? 

But the nutter butters you can buy from the store are, of course, loaded with carbs and sugar. 

Well, these homemade keto nutter butter cookies solve that problem. 

Basically, this recipe takes two keto peanut butter cookies - that are just to die for on their own - and sandwiches a thick and creamy peanut butter filling between them.

Honestly, if you love peanut butter, then this is the only keto cookie recipe you'll ever need.

That said, I do have a few other keto cookie recipes that are to die for as well - like these keto magic cookies, these keto thin mints, and these keto chocolate chip cookies. So, definitely give one of these recipes a shot when you're craving something other than peanut butter.

INGREDIENTS YOU'LL NEED

One of the best parts about this copycat nutter butter cookie recipe, is that you only 6 ingredients to make them. 

And I'm pretty confident that you'll have every one of these ingredients ready to go. 

For the cookies, you'll need:

• 4 large egg yolks 
• Just less than ⅔ cups no sugar added peanut butter
• ¼ cup blanched almond flour
• 1 teaspoon vanilla extract
• ½ heaping cup Confectioners Swerve

And for the filling:

• 2 tbsps. peanut butter
• Just less than 1 tbsp. Confectioners Swerve 
• ½ - 1 tbsp. almond milk 

You've got all of these, right?

Oh, and by the way, you can put all of these ingredients to good use by making these keto tagalongs next. They're shortbread cookies with peanut butter on top, covered in chocolate - so so good. 

 LOW CARB PEANUT BUTTER TO USE

So this recipe will make the most peanut buttery cookie possible. I'm talking peanut butter, on top of peanut butter, on top of peanut butter. 

And if we're using all that peanut butter, we want to make sure it's low carb.

Keep in mind that not all peanut butter is created equal. Most peanut butter has added sugars in it, adding unnecessary carbs to your cookies.

So, to keep them as low carb and keto-friendly as possible, I recommend finding a natural peanut butter like this one from Smucker's that has no sugar added to it. 

Also, make sure the peanut butter is on the runny side - this will allow it to mix better and give you the best results for your cookies.

KETO FRIENDLY FLOURS TO USE 

For our cookie dough, we will be making almond flour peanut butter cookies. 

And if you're a regular making my recipes - first off, you're the real MVP - and second, you probably know that my go-to almond flour is this blanched almond flour by Blue Diamond. 

This is my favorite keto flour to use because it has the lowest carb count out of all the other almond flours, and it works really well in every recipe.

But, if you don't want to use almond flour or have an almond allergy, you can use either walnut flour or sunflower seed flour to make these keto peanut butter cookies. Both are low carb flours and can be substituted with almond flour at a one-for-one measurement.

FLOURS TO AVOID

Now, a flour you DO NOT want to use to make these nutter butters is coconut flour.

Although coconut flour is a low carb flour and can be used in keto recipes - like to make these keto brownies - it will not work well for our cookies. 

Since coconut flour is a highly absorbant flour, it will cause these cookies to dry out and be super crumbly - if they even turn out at all.

SWEETENING OUR KETO NUTTER BUTTERS

Adding a touch of sweetness to our cookie dough and peanut butter filling makes these keto cookies go from the best cookies in the world to the best cookies in the universe. 

And, of course, we will be sweetening our keto peanut butter cookie sandwiches in a sugar-free way.

Doing this doesn't just make these low carb cookies - it actually makes them healthy too! Crazy, right?

With that said, we will be using Confectioners Swerve to sweeten up both our cookie dough and the filling. 

Using Confectioners Swerve will give our cookies the same amount of sweetness as using sugar would, but with 0 NET CARBS and 0 Calories. 

Another sweetener you can use is Lakanto's Confectioners Monk Fruit. It has the same sweetness level as Swerve, and it's totally keto friendly too.

SWEETENERS TO AVOID

Ok, so there are a couple of sweeteners you'll want to avoid using to make these cookies, mainly stevia and xylitol.

Stevia in its purest form is up to 300 times sweeter than sugar, and that is just way too sweet to use. And most companies mix Stevia with maltodextrin, maltose, and dextrose. All are essentially other names for sugar and will knock you out of ketosis. 

Xylitol is another sweetener you'll want to avoid. Although it is labeled as "sugar-free," it actually has half the carbs and half the calories as regular sugar. 

So, make sure you use one of the recommended keto-friendly sweeteners above.

HOW TO MAKE KETO NUTTER BUTTERS

Before we start making our cookies, I want to mention that I suggest using a food scale if you have one. The food scale will allow you to get the most accurate measurements since some measurements aren't exact. 

However, if you don't have one, no need to worry - your cookies will turn out just as delicious and just as irresistible. 

Now gather your ingredients and let's make these keto peanut butter cookie sandwiches! 

STEP 1: MAKING THE DOUGH 

The first thing you'll want to do is preheat your oven to 350°F (177°C).

Next, separate the egg yolks from the whites, and then add the yolks to a large bowl, along with the rest of the cookie ingredients listed above. By the way, if you're looking for something to do with the leftover whites, you can make this keto bread with them.

Anyway, once you've added everything to the bowl, you're going to give the ingredients a good mix with a spatula until a thick peanut butter dough starts to form.

Then, once it forms, use your hands to shape a ball of dough out of it.

STEP 2: BAKING YOUR COOKIES

So, once you have the dough ball, you can use a tablespoon-sized cookie scoop to scoop out some dough. Then use your hands to shape the dough into cookies. 

And this recipe will make 12 thick keto peanut butter cookies. But feel free to make them a bit thinner if you want to make more cookies out of the dough.

Anyway, next add all of your cookies to a baking sheet lined with parchment paper, then pop them in the oven for around 7 to 10 minutes tops.

After you take them out, let them set and cool down on the tray so they can firm up. That said, the cookies will have to cool for about an hour to set, so be patient. They'll most likely be extremely soft when they first come out of the oven, and if you rush things, you'll ruin the cookies.

STEP 3: MAKING THE PEANUT BUTTER FILLING

Ok, so once the cookies set, you can make the peanut butter filling.

And making it is super easy. Just add all of the "filling" ingredients listed above to a small bowl, and mix them until a thick peanut butter sauce forms. 

By the way, the amount of almond milk you'll need to make the sauce come together will vary depending on how runny your peanut butter is.

So, just keep that in mind.

STEP 4: ASSEMBLING THE COOKIES

Once the peanut butter filling is ready to go, you can get your cookies out and pair each of them up with a cookie that's a similar size.

Then you're going to add a teaspoon of the peanut butter filling to the bottom of one cookie and sandwich it to the bottom of another cookie. 

Now, all that you have left to do is repeat this process until you've made peanut butter cookie sandwiches out of all of your cookies. 

And then you're all set to eat them!

STORING THE COOKIES

One of the best parts about making cookies as delicious as these is being able to look forward to eating them throughout the week. 

And you can enjoy these cookies all week long since they will last for up to 7 days at room temperature. Just make sure you put them in an airtight container. 

That said, I prefer to keep my cookies at room temperature, but you could also refrigerate them if you'd like. 

Also, if you want a frozen treat, you can store these keto nutter butters in the freezer for up to 6 months. 

Just place the cookies in a single layer on a baking sheet in the freezer first, then once they are completely frozen, transfer them to freezer-safe bags.

NUTRITIONAL INFORMATION 

Ok, so as I mentioned earlier, this recipe makes 12 thick nutter butter sandwiches. And if you make 12 cookies, each one will have just over 3.5 NET CARBS. 

That said, here's the rest of the nutritional information for 1 cookie sandwich:

• 275 Calories
• 22g Fat
• 6.25g Carbs
• 2.5g Fiber
• 3.75 NET CARBS 
• 10g Protein 

So if you make thinner cookies out of the dough, the carb count and the rest of the macros will be lower. 

And that my friends are the best keto peanut butter cookies you can make.

Healthy, low carb, and triple peanut butter all in one cookie - you truly can't beat it. 

If you have kids, they won't stop asking you to make these keto nutter butters once they try them.

And I guarantee you'll love the cookies just as much as them - so you should probably just make these keto cookies every week. 

Anyway, if you make them and tag me on Instagram  - I'd love to see how they turn.
