Peanut butter cookies! I just can't get enough of them.
I recently posted my third (baked) keto peanut butter cookie recipe, thinking I had reached full circle. It was this coconut flour peanut butter cookie recipe, joining my very lovely almond flour peanut butter cookies and these classic keto peanut butter cookies.
Here they are - 3 beautiful cookie stacks:
The Coconut Joy 
The Almond Twist 
The Classic
Turns out there was still one recipe missing - these keto no bake peanut butter cookies!
Peanut butter is just PERFECT for no bake keto recipes. I have quite a few on my website (listed at the end of this post). For these cookies, all we're doing is mixing smooth peanut butter with coconut flour. It's then covered in chocolate. Pure pleasure!
Regular peanut butter no bake cookies are made with oats. Since oats are high in carbs, I'm using coconut flour as a low carb, gluten free alternative. This way, one cookie is just 1.6g net carbs.
I know what you're thinking - Do low carb no bake cookies taste like REAL cookies? The answer is: They taste more like cookie dough or maybe really fudgy pb cookies. Totally delicious.
I think these cookies are ideal for the summer. Firstly, because there's no need to turn on the oven. And secondly, because they are nice and cool as they are stored them in the fridge or in the freezer. However, I know that a true peanut butter connoisseur will appreciate them all year round!
Ingredients for no bake keto cookies
- Peanut butter - I used a smooth creamy peanut butter. Crunchy peanut butter will also work. Choose a natural peanut butter with ideally just one ingredient - peanuts. I like Meridian or ManiLife.
- Coconut flour - You may need to add a little less or more coconut flour depending on how runny your peanut butter is. Instructions are below.
- Sweetener - I used a golden erythritol monk fruit sweetener, which is a 1:1 sugar replacement. You can also use powdered erythritol xylitol or allulose if you prefer a smoother result. Alternatively, use a sugar free syrup. As you're adding more liquid when using a syrup you may also need to increase the coconut flour to achieve the same dough consistency.
- Vanilla extract and sea salt - Neither are essential, but both lend additional flavour.
- To coat: chocolate and coconut oil. Both sugar free chocolate chips like Lily's or 90% dark chocolate such as Lindt are fine here. I also like to add 1 tbsp of coconut oil to make the chocolate a little softer and keep it from chipping.
How to make keto no bake cookies
Mix together all ingredients except for the chocolate and coconut oil in a bowl. You can use a fork for this. Option to also add a pinch of sea salt if your peanut butter is unsalted.
Form dough balls and put them on a baking sheet lined with parchment paper. Flatten them with your fingers. Freeze until set - this takes about 1 hour.
Melt 90% dark chocolate or sugar free chocolate chips plus the coconut oil in a water bath or in the microwave. Using 2 forks, dip the cookies into the chocolate. Sprinkle with a little more salt and place back in the freezer for 5 minutes to set.
Store cookies in the freezer or in the fridge.
Recipe tips
Peanut butter can vary in consistency fro runny to hard. Mine was somewhere in the middle. I recommend that you start with ⅓ cup or 40g of coconut flour and then add more if your dough is still too soft. I ended up using ½ cup or 60 grams of coconut flour. You should be able to press fork marks into the dough that do not flatten out by themselves and be able to roll balls that keep their shape.
It's also worth noting that by using granulated sweetener like I did you will be able to detect a slight graininess in the cookies. This did not bother me, but if you are after a smooth dough, do use powdered sweetener or even sugar free syrup.
Variations
For chocolate peanut butter cookies, add 2 tbsp cocoa powder into the dough.
To increase the fibre content, add 2-3 tbsp flax meal.
Feel like a bit of crunch? Add 2-3 tbsp hemp hearts (hemp seeds) or coconut flakes into the cookie dough. Or, in fact, throw in a handful of chocolate chips for chocolate chip cookies!
1-2 tsp cinnamon will give the cookies a bit of autumn flavour.
Last but not least, the million dollar question: Can you make low carb keto no bake cookies without peanut butter? The answer is - of course! Simply replace the peanut butter with almond butter or any other nut butter. Increase the coconut flour amount if needed - almond butter tends to be more runny.

I love this keto treat as do my kids. I added some spirulina powder for a little extra nutritional value.
Thank you thank you

Katrin,
I love your recipes! Have you worked with lupin flour? I just made fried green tomatoes using lupin flour. I added a small amount of hemp hearts, sea salt and freshly ground pepper to the flour. Eggs and whipping cream were the other part of the dredge. They were delicious.
Of all the keto recipes online, I like yours best. If you start to work with lupine flour, please let me know.
Thanks,
Karan

HI Karan, I've actually just bought a bag and want to start experimenting. BE sure to join my newsletter so I can keep you updated.
Sara says
Hi, 1/4 cup Coconut flour weighs 13g not 60g....
Katrin Nürnberger says
Hi Sara, this peanut butter cookies recipe uses 1/2 cup coconut flour which weighs 60 grams.
Daniela Affolter says
Whipped these up tonight, they are so easy to make and so delicious! I used my Thermomix to make my own peanut butter, coconut flour and to temper the chocolate. We are in covid lockdown at the moment...so could not go shopping. I might make another batch tomorrow
Katrin Nürnberger says
So glad you like the recipe!
Sharon says
Fabulous! I had my doubts when I read coconut flour in the recipe so I only made a half batch. Bad idea! These are awesome treats, not dry or crumbly. Next time I'm making the whole thing! Thank you for sharing your recipe with us.
Katrin Nürnberger says
So glad you like the cookies!
Melissa says
These look delicious and I'm very happy to have found your site. I am not able to tolerate coconut flour, it causes digestive issues. Do you think almond flour would work?
Katrin Nürnberger says
Hi Melissa, yes you could use almond flour. But you will definitely need more - up to 3x the amount, depending on how firm your peanut butter is. Almond flour absorbs less moisture than coconut flour.
Jennifer says
*****Please make aware that the erythritol xylitol or allulose is poisonous to dogs*****
With that being said the recipe was delicious.
Katrin Nürnberger says
Hi Jennifer, from my research it's actually only xylitol that is dangerous for dogs. Glad you like the recipe!
Barb Luhrsen says
Do you use sugar free peanut butter in this recipe? My granddaughter is 8 and just found out she has Type 1 diabetes so I want to make sure I do it correctly!
Katrin Nürnberger says
Hi Barb, my peanut butter contains only peanuts and a little salt. Try and find a brand that contains only peanuts and definitely no added sugar.
Rosália says
Excelente
mary lucereo says
Can you use regular flour instead of coconut flour? Seems it would be terribly dry without any oil or other liquid
Katrin Nürnberger says
I would not recommend it.
melissa knue says
I'm gonna dip the cookies in bakers chocolate for even lower calories. Should still have a sweet taste. Hopefully no strong after taste.
Katrin Nürnberger says
You could add some sweetener to the chocolate once you have melted it. 🙂
Richard C Miller says
I love the recipe and will probably use a variant of it. If you or any readers are eating peanut butter and not getting results on keto, there is a good reason. Peanuts are legumes (think beans) and are more likely to spike blood sugar. Some people do not tolerate peanut butter on keto and should switch to almond butter.
Katrin Nürnberger says
This recipe will definitely work with almond butter as well. I find that mine is always a little more liquid than peanut butter so you may need a touch more coconut flour.
