This Keto Peanut Butter Cookies Recipe is pretty easy!

How to make Keto peanut putter cookies

Combine all the ingredients and mix until incorporated.

Then using a small cookie scoop scoop out dough and make balls. Place on a parchment paper lined baking sheet and press with fork to make a criss cross pattern.

This Keto Peanut Butter Cookies Recipe does not require chilling time. You can bake them right away. These cookies don’t spread.

I usually bake mine at 350 F for 12-15 minutes.

This Keto Peanut Butter Cookies Recipe makes cookies that are soft on the inside and slightly chewy on the outside.

They are very easy to whip up at the times when you are craving a keto snack or dessert, but don’t feel like eating dark chocolate.

One of these quick and simple low-carb desserts that you can make any time in under 30 minutes.

There is nothing worse than having to wait to chill a dessert, bake for a long time or letting it set.

These are nothing like this. Foolproof and simple.

There are so many variations of the recipe for these Keto cookies with peanut butter, but I like to keep things plain and with minimal ingredients.

Protein powder in cookies

I know that some people add protein powder to their peanut butter cookies.

Keto Peanut Butter Cookies Recipe on top of each other

I’ve tried some recipes, but the cookies were too dry.

That’s why I think that the combination of just peanut butter and powdered low-carb sweetener is just enough to achieve cookies that don’t fall apart, but still stay moist on the inside.

The list of ingredients is surprising!

No butter!

There is no cream cheese or nut flour.

No protein powder!

  • Peanut butter (creamy or crunchy)
  • Powdered erythritol
  • Egg

Can I use powdered peanut butter in these cookies

Looking into substituting powdered peanut butter for regular in this recipe?

I do not recommend it. Powdered Peanut Butter DOES NOT WORK in this recipe!

What sweetener to use for Keto cookies ?

  • For BEST results, use confectioners (powdered) sugar-free, low-carb, keto sweetener.
  • I use Swerve Powdered sweetener.
  • Monk fruit also works, but keep in mind that the cookies will be sweeter.
  • Truvia for baking could be used.
  • If you decide to stick to granulated sweetener, keep in mind that you still might be able to feel the granules in the texture of the baked cookies. I don’t personally like that.

I try to avoid the granulated sweeteners in cookie recipes like this Keto Peanut Butter Cookies Recipe, because I just love the cookie texture when using powdered.

Yes, because eggs help to hold the dough together.

Flourless cookies with pb

Yes! There is no flour, no gluten-free flour, not even nut (almond), flour used in there.

This Recipe for Keto Peanut Butter Cookies  requires baking.

Because of the egg, you can not consume these raw.

I usually bake mine for 12-15 minutes, until the tops are set and start to turn golden.

The size of these cookies is about 1.5 tbsp of dough.

This Keto peanut butter cookie recipe makes 9 cookies.

Double or triple it if you’d like to make more.

This is the best and my most-favorite recipe for Keto peanut butter cookies.

Crispy cookies

These Keto peanut butter cookies ARE NOT CRISPY.

Please note that these cookies are rather rubbery than crispy, due to the lack of flour. Please DO NOT expect the recipe to result into crispy cookies.

  1. Aw man, I used Skippy Crunchy PB, as it’s the lowest carb PB I saw, and doubled the recipe. I don’t know why, but the cookies ended up extremely rubbery. Any idea what I may have messed up? I used confectioners Swerve, and the sweetness was right on. The texture was the only problem, and it unfortunately ruined it. I also used a little bit of vanilla extract.

  2. I had a really hard time getting ten cookies out of this recipe, I got 6. I used a natural style peanut butter that I thought looked similar to the one in the video but maybe it was too loose. Definitely couldn’t roll into balls. They smell good though, so maybe the texture will be okay. Fingers crossed!

  3. Super easy and absolutely addictive ! Added a vanilla pod so mine was a 4 ingredient recipe. Thanks for sharing !
