The ingredients we need for these keto peanut butter cookies are almond flour, baking soda, softened butter, unsweetened peanut butter, keto friendly brown sugar sweetener, egg, and vanilla. A few more ingredients than the 3 ingredient cookies, but so much better!
⅔ Cup Almond flour - for coconut flour, use ⅓ cup
1 teaspoon Baking soda
½ Cup Unsalted butter, softened
1 Cup Creamy peanut butter-unsweetened - feel free to use any nut butter you like. Almond butter works well.

How to make keto peanut butter cookies
This section explains how to make this keto peanut butter cookie recipe, step by step. For a full printable recipe, see the recipe card below.
line 2, 9x13 cookie sheets with a silicone baking mat or parchment paper.
Mix almond flour and baking soda in a medium mixing bowl and set aside.
Add the butter, peanut butter and brown sweetener to the medium mixing bowl with the almond flour and baking soda, mix until smooth. Add the beaten egg and vanilla and mix again until smooth. You can use an electric mixer or a stand mixer.
Once the dough is all mixed together, we need to refrigerate it for about 20 minutes to let it firm up. Here is how the peanut butter keto cookie dough should look after being refrigerated.
Scoop 2 tablespoon size cookies evenly spaced on the baking sheets.
I used a ⅛ cup measuring spoon to keep the cookies even. You can also use a 2 tablespoon cookie scoop.
There is no need to roll this into cookie dough balls, but you can if you like the cookies to be a little prettier. I just scoop them on the baking sheet and bake them as is.
These perfect keto peanut butter cookies makes 15 cookies and they bake in a 350F oven for about 15 minutes.
If you want them to be less calorie dense, you can divide them into smaller cookies.
They will spread into nice rounds and the edges will get crispy. The texture is so good! These remind me of nice big bakery style peanut butter cookies.
Pro tip:
- Use whatever nut butter you like. Almond butter works well in this recipe. Just be aware that sunflower seed butter will turn the cookies green due to a chemical reaction.
Can I use coconut flour instead of almond flour?
Yes! You would use ⅓ of a cup of coconut flour in place of the almond flour for these low carb peanut butter cookies.

Jennifer's tips
- I used a room temperature container of natural peanut butter. If your peanut butter has been sitting in the refrigerator, you will need to leave it out to soften for a bit where it is more pourable.
- Almond butter can be used in place of the peanut butter
- If you do not have the brown sweetener, you can use regular granular but the texture may be a little different.
- If you would like cookies that are less calories dense, you can make them smaller.

Sl says
Sounds so yummy! My diabetic daughter would love them. Is the nutrition info for total carbs or net carbs? She has to give insulin for total carbs. Thanks you for your help. Love your recipes.
Jenn Davis says
Jennifer, Which sweetener Do You (and your FamJam) prefer? Your link takes me to several, likely becuz Amazon.com is in the US and I'm in Canada. Due to filters that instead show me what is available for Canada, could you state the sweetener that you like best? I know it comes down to personal tastes, but I would like to know Your Pref. TIA!
Jenn Davis, in Canada!
jenniferbanz says
I use Lakanto or Swerve
Rhonda James says
So Yummy! And so filling that I found myself not feeling like I wanted more than 1 cookie for dessert! Thank you Jennifer!
NL says
Easy to make and delicious!
Gabriel says
Please clarify. How many net carbs for one cookie? Your title says 2 net carbs. Then you state "1 net carb per cookie!" But your NUTRITION shows 2 carbs.
Serving: 1cookie | Carbohydrates: 4g |Fiber: 2g. That equals 2 net carbs.
PLEASE EMAIL ME. YOUR RECIPE LOOLS GREAT. I just want to make sure my numbers are right. Thank you
jenniferbanz says
Sorry about that...they are 2 net carbs
Isabel says
Are you saying NOT to use Lakanto Golden for this recipe?
Julie says
I used Swerve brown "sugar" sweetener. This overpowered the peanut butter. I packed it like real brown sugar when measuring. Is that the correct way to measure brown sugar substitutes?
Is Lakanto less sweet than Swerve? I need to try a different brown sugar substitute although the cookies baked up well.
jenniferbanz says
I didn't pack the sweetener. I made these with Lakanto and the cooling was really strong.
