Melty Keto Cookies (Peanut Butter Chocolate Chip)

Good morning, everybody!

I’ve gotten several questions about a cookie I’ve posted on Instagram multiple times now. They’re a peanut butter chocolate chip cookie that I made based off of a sugary recipe I found somewhere… that I’ve since forgotten. Whoops. I apologize for not putting this post together sooner, but it’s been a damn long school year. The end is in sight – this is my last week of classes! With a little bit of breathing room, I decided to finally put this recipe down on paper, as it were, and post it here on my blog. So here goes.

I call these “Melty Keto Cookies” because when my non-keto homie taste-tested them for me, she got weirded out by how they melt in your mouth. That’s the erythritol. I’m not a huge fan of erythritol because I think it has a funky aftertaste, but in this recipe the peanut butter flavor overpowers it, so it’s all good! Fresh out of the oven and piping hot, they really do melt in your mouth. The rest of the time, when they’re cool, they just feel like they are!

I have to confess that I don’t make a lot of my other desserty recipes on here very often anymore. I can’t think of the last time I made my peanut butter cup fat bombs, for instance. I’ve whipped up some cheesecake fluff here or there, but that’s been it, other than these cookies. I love these damn cookies. Hot and soft chocolate chip cookies have always been my favorite dessert, and these really hit the spot for me, even more so than my other chocolate chip cookie recipe. These are that good.


Don’t mind Starfall. He wanted to pose all majestic af for you guys.  Isn’t he gorgeous?


  • 1 cup (250g) natural peanut butter, I prefer crunchy for these since it gives a bit of texture
  • 2/3 cup erythritol
  • 1/2 cup sugar free or dark chocolate chips
  • 1 egg
  • 1/2 tsp baking soda
  • 1/4 tsp salt


Preheat your oven to 350.

Throw all the ingredients into your mixer, or mix by hand until fully incorporated.  This will not make a nice lump of dough – it’ll be all chunky and broken up, as pictured above.

Grab dough by the handful, roll it into a ball, and then squish it down into a rough approximation of a cookie shape on your cookie sheet.  I like to use silpats to keep my cookies from sticking, although that may not be necessary here… these cookies are oily due to the peanut butter base.  But I’m not going to risk a perfectly good batch of cookies to test it, so let me know if you try and they don’t stick!

Bake for about 10-12 minutes.  These cookies don’t really go “golden brown” so try to just eye them and see if they look mostly not raw.  I say that because we’re still not done with the baking process.

Once your cookies are out of the oven, RESIST!  DO NOT EAT THEM!  THEY ARE NOT DONE BAKING!  Let them rest on the hot cookie sheet for another 10 minutes.  This will finish up some residual baking.  Because these cookies are not made with flour, they lack the elasticity granted by gluten.  If you try to pick them up straight out of the oven, they will crumble and fall apart and you will be left holding a bit of molten cookie, crying because it’s wasted.  Don’t be that person.  You don’t need that negativity in your life.

Ten minutes later, they’ll have a nice firm bottom (that’s what she said) and will be nice and melty in the center!

These bad boys clock in at about 176 calories each; 6g of protein, 1g net carbs, and 14g of fat.  Awwwwww yiiiiissssss.  If you don’t eat the whole damn batch, you can store them in an airtight container for several days.  Not gonna lie, sometimes I carry 2 or 3 with me to work as breakfast.  I like how they still feel all melty on the inside even when they’re cold and old.  Breakfast of champions right here!

  1. Hey Britt,

    I see you mention your Amazon Affiliate account, but I don’t see a link to the ingredients in your blog post. Just a heads-up, so you can hopefully see some affiliate $ from your post.


    • Thanks! But I have to ask – are you running an ad blocker? There are links to them directly under the disclaimer, but you can’t see them if you have an adblocker enabled! I can still see them on my end so I think they’re functioning as intended. I guess I could always embed them like text in the ingredients list… hadn’t thought about that… I just don’t like advertising to be so in-your-face.

  2. These look good! Just a question: Do you feel like these may “hold together” a little better if I were to add a little bit of almond flour? (or coconut flour?) – just wondering how it may affect the cookie. Thanks!

  3. So these are just cooked peanut butter? No flours of any kind? Awesome

  4. I used a little less sugar but these turned out great! I also used your beading recipe for chicken tenders and mozzarella sticks and it was great as well. Thanks! Love your blog!

  5. I just did my owm math on these and came up with about 5 carbs per cookie. I wish it was only 1 :(
    My PB had 4 net carbs per 30g. Multiplied by 8 (to get the 250g of PB) gives 32 net carbs just for the PB. (so 2.6 carbs per cookie)

    My chocolate chips (Lily’s Dark Chocolate) has 5 net carbs per 14g. I got 85grams in 1/2 cup. That comes to another 30 carbs for the batch, or 2.5 per cookie. So 5 carbs per cookie.

  6. I switched to a keto diet along with my girlfriend back in August. These have been a godsend. Thanks for posting the recipe. We love the peanut butter cups too!

  7. ***WARNING*** I call bullshit. I looked up the carbs on all of your items and you are no way at 1carb. With that PB, you are closer to 8 carbs.

    My PB only has 4net carbs and I used half the chocolate from a 100% cocoa bar, cracked. I came out to 6 net carbs.

    Double check your math and stop misleading people. This is highly irresponsible of you.

    • I am not a doctor, or a nutritionist, or anything like that…. as I’ve stated repeatedly on my blog. Those are the counts that MyFitnessPal recipe creator came up with when I added the ingredients and divided it by serving size. I don’t see how me posting that is “highly irresponsible” and how I’m “misleading people.” Always double check what you put in your mouth.

  8. Love the recipes, great cat, so regal!

I love comments, and read every last one. Talk to me!
