Ingredients

  • Almond Flour – I prefer using blanched ultra-fine almond flour instead of almond meal. It has a finer texture, and it works better in this recipe. Are almond flour recipes keto? If used with other keto-friendly ingredients, absolutely!
  • Natural Peanut Butter – Yes, peanut butter is keto-friendly! Always make sure you use unsweetened and fresh peanut butter. An old peanut butter jar tends to dry out and would not make as delicious cookies. You can either use salted peanut butter or unsalted peanut butter. If you use salted peanut butter, don’t add extra salt to this recipe.
  • Coconut Oil – I use unrefined coconut oil. Feel free to use refined coconut oil if you don’t like coconut flavor.
  • Baking Soda
  • Salt – optional, only if your peanut butter is unsalted.
  • Sugar-free Crystal Sweetener – I used erythritol in this recipe. Feel free to replace it with monk fruit sugar if preferred. Both options are 100% sugar-free and have no carbs. If you are paleo, coconut sugar will work but the recipe won’t be low carb anymore!
  • Xanthan Gum – optional but recommended to make sure the cookies hold any time!

Instructions

These cookies are very simple to make.

  1. Preheat the oven to 350°F (180°C)
  2. Combine all the ingredients in a bowl.
  3. Combine them with a spatula.
  4. Divide the dough into 8 cookie dough balls that you flatten with forks by making a criss-cross pattern on a piece of parchment paper.
  5. Bake the cookies for 10 minutes on a cookie tray.
  6. Cool them down for another 10 minutes on a cookie sheet and another 10 minutes on a cooling rack.

Expert Tips

Following are my tips to make the most delicious sugar-free peanut butter cookies:

  1. Follow the baking time. It takes 10 minutes, not more. The cookies will be very soft and will look undercooked, and that is what you want!
  2. Cool them down for 10 minutes on the cooking tray. Please don’t touch them. Start your timer and wait 10 full minutes. Now they are half hard.
  3. Cool them down for 10 minutes on the cooling rack. Transfer each cookie gently to a cooling rack by sliding a spatula under the cookie. Wait for another 10 minutes and let the magic happens!

Your keto peanut butter cookies with almond flour are now crunchy, buttery, and delicious!

So now, let me know what you think of these easy low-carb peanut butter cookies?

You can also use some vanilla essence or vanilla extract for a delicious vanilla taste.

Storage Instructions

These cookies can store really well as long as you follow some basic principles.

You can keep them for at least 3 weeks in a sealed jar, kept in a cool, dry place, away from direct sunlight.

Heat, moisture, and air would oxidize and degrade the taste of these cookies. But if you store them sealed, they will taste delicious for longer.

You can also freeze them for up to 3 months in individual ziplock bags or in small airtight containers. Again, try to remove as much air as possible to reduce the moisture. Thaw them in the fridge, or pop them in a toaster or oven to reheat.

Allergy Swaps

If you are allergic to any of the ingredients, you can do the following swaps.

  • Almond Flour: you can substitute almond flour for oatmeal or sunflower seed flour. Do not use coconut flour or flaxseed meal, they are too moisture-absorbent due to their higher fiber content.
  • Erythritol: you can replace the erythritol with any other crystal sweetener such as allulose, tagatose, or coconut sugar (if not keto). Do not use Monk fruit extract, Stevia extract, or any liquid sweetener.
  • Peanut Butter: if you are allergic to peanuts, you can swap the peanut butter for any other seed butter or nut butter such as Almond Butter, Sunflower Seed Butter, or Cashew butter. Make sure to use a fresh jar of natural nut or seed butter so it’s runny. Do not use Crunchy Peanut Butter or any peanut butter that has sugar as an ingredient.
  • Xanthan Gum: Xanthan gum is optional in this recipe. It helps make the cookie hold together, but you can do without it. Do not use a flaxseed egg instead, it would make the dough too wet.
  • Coconut Oil: You can pick any other oil with a high-enough smoke point, like avocado oil but the cookies will taste different (a bit like avocado).

Frequently Asked Questions

How Many Carbs Are In Keto Peanut Butter Cookies?

These peanut butter cookies are made with only keto-friendly ingredients and come at 4.3 grams of net carbs each.

Peanut butter is a good keto-friendly ingredient as it contains only 1.4 grams of net carbs per serving of two tablespoons!

However, store-bought peanut butter is not always made with only peanuts. In doubt, you can always make your own peanut butter. It’s effortless and rapid!

This recipe is also made with Almond Flour, and it is one of my favorite keto-friendly flours with only 10.6 grams of net carbs per 100 grams. Compare this with regular wheat flour that tops up at 75 grams of net carbs per 100 grams!

All this makes these Peanut Butter Cookies a great keto-friendly snack!

How Do They Taste?

So now you wonder what makes these keto peanut butter cookies so special? Well, compared to regular cookies, they will be super soft when out of the oven.

Like really soft! You might even think that they are undercooked. And you will think there is NO way this recipe will harden and works! But it does.

These cookies are egg-free and need more cooling time than baking time to become crunchy and delicious. 

Can I make different flavors?

The best way to tune the flavor of these cookies is to add sugar-free chocolate chips to make perfect peanut butter chocolate chip cookies.

Are these cookies gluten-free?

Yes, these cookies are 100% gluten-free, made with only low-carb ingredients.

Instructions

  • Preheat the oven using the fan-bake mode to 350°F (180°C).
  • Line a cookie sheet with a piece of parchment paper. Set aside.

Make the cookie dough

  • In a large mixing bowl, add all the ingredients: peanut butter, melted coconut oil, erythritol, almond meal, baking soda, salt, xanthan gum, and vanilla essence.
  • Combine with a spatula until it forms a thick cookie dough. 
  • Divide the dough into 8 large cookies (or 12 smaller cookies). 

Bake the cookies

  • Place each cookie ball on the prepared cookie sheet. Flatten slightly with your hand palm, then use a fork to flatten more and create a lovely fork print on top of your peanut butter cookies. Those cookies won't expand while baking, so there is no need to leave more than half a thumb space between each cookie.
  • Bake for 10 minutes or until the sides are golden. The cookies look uncooked, they are VERY soft after baking, and that is what you want!

Cooldown 10 minutes on the cookie tray

  • Remove the tray from the oven and let cool down for at least 10 minutes on the tray, at room temperature. I know this isn't easy to believe they will harden, but they will! Don't touch them. Just let the magic happens.

Cooldown 10 minutes on the cooling rack

  • Now, the cookies are a bit harder but still soft, so carefully slide a spatula under each cookie and transfer them one by one onto a cookie rack to cool down for 10 more minutes. Trust me. It is worth waiting for! I know it smells good, but wait for the magic to happen.
  • After 20 minutes, the cookies are ready to eat, but if you love them crunchy, wait until they reach room temperature – should not take more than 20 more minutes. They will end up very crunchy, hard, and buttery. 
  • Store in a cookie jar – glass or metal – for up to 2 weeks. 
Cooldown: These almond flour peanut butter cookies are mainly made of healthy fat, they don’t contain eggs, and they need the 2 steps of cool down to get hard and crunchy. Don’t skip these steps!
Sugar-free sweetener: you can use erythritol or monk fruit sugar in this recipe.
Paleo sweetener: Coconut sugar would be a good alternative (but it is not sugar-free). Use the same amount as erythritol. This would make this recipe not suitable for a keto diet!

    Wow… a Keto recipe that actually worked! 😀 I made these exactly as written and they turned out perfectly. Thank you for the great recipe.
    P.S. Why are the majority of comments always from people who DIDN’T follow the recipe reporting what they did differently? I don’t get that…

  2. 5 stars
    I special-ordered the monk fruit sweetener and xantham gum from Amazon and followed the recipe to a T, except that I decreased the sweetener by a couple of tablespoons. The cookies came out perfectly soft in the middle and a little crispy on the outside. This was my first time trying a keto baking recipe and I can’t believe it tastes as good as a traditional PB cookies.

  3. 5 stars
    It fees like such a treat to finally find a recipe for a low carb cookie that has crunch! These are amazing, thank you for the wonderful recipe and the care in detailing the magic to achieving the crunch! Unlike others I didn’t have any issue forming the cookies, however, I managed to find a superfine almond flour/meal (in Melbourne, Australia) so perhaps that made the difference. Love your recipes!

  4. 5 stars
    Well, this was my first foray into baking biscuits and into Keto. All would have been better had I included the Baking Soda which I even ticked then left it on the side!! Also learnt to look at what I was doing when setting the timer! 1st ten minutes extended cooking to 15-20 minutes resulted in somewhat chard but scrumptious cookies. I promise to do better next time.
    Like others, I had difficulty prepping the balls for the cookies it crumbled very easily – possibly due to the quality of the Almond Flour we have. However, I will cook them again once we’ve sharpened our teeth on the sad charcoaled edged results of this time. Thanks for all your posts and recipes. J

    Made this today and they worked out! My erythritol hasn’t arrived yet so I used around 2 tablespoons of liquid saccharine, which is diabetic-friendly. I dislike peanut butter (funny, I know!) but these were so lovely. I really kicked cravings to the curb with a couple mini cookies. Will use almond butter next time! ♪

  6. 5 stars
    These are so good! Best dietary requirement biscuits I’ve tried to date. I wonder if they would work with coconut added??

  7. I actually tried it with the peanut flour and by adding more coconut oil and cooked for a shorter time (kept eye on them), they come out mighty fine. Thank you for your recipe and stay safe, happy and healthy

  8. Made these tonight and they were absolutely delicious, and let me tell you, I’ve been trying all kinds of recipes to satisfy my type 1 diabetic grandson and he gave this recipe the thumbs up, that’s AWESOME.. so thank you for sharing

    • Unfortunately you can’t swap almond flour by peanut flour, peanut flour is much higher in fiber and it dries food quickly. It will be a new recipe to create, Enjoy the recipes on the blog, XOXO Carine

  9. 5 stars
    I have made this many times. Gave to friends too and they loved it. Thank you for all the wonderful recipe. You site is always in my favorite tab.

  10. Hi Carine — I don’t like erythritol. I have pure monk fruit sweetener (no other sweetener additives), but don’t know how much of the pure monk fruit to use in the peanut butter cookie recipe. Can you educate me on this? Thanks

    • The cookies won’t hold at all with pure Mon fruit. Erythritol melt, crystallised and solidify the cookies. I only use pure monk fruit in drinks, never in baking as it doesn’t add texture. Enjoy the recipes on the blog, XOXO Carine

    • Sure, as soon as you are using natural nut butter with no added oil or sugar and a fresh jar, it will work. XOXO Carine

    • The cookies don’t need the gum, it works without they can simply be more fragile. However a flax egg will add too much liquid and they won’t work. Enjoy, XOXO Carine

  11. I tried the recipe with crunchy peanut butter, because that is how my husband likes his peanut butter cookies, and found that it is way to dry to use, so I ended up adding in creamy peanut butter to help it come together. I was making a double batch and used about 3/4 cup crunchy to 1/4 cup creamy, but needed about another half cup of creamy. Took about 2 minutes longer to bake and they turned out softer with all the extra peanut butter, but they are delicious.

    • I am glad you find a way to fix them! However, that is the reason why I always recommend fresh, runny peanut butter in my recipe with no added oil or added sugar. That is the best product to avoid a too dry or too soft cookie. I am sure it wil get even better next time you make them ! Enjoy the recipe here, XOXO Carine.
