Keto Peanut Butter Cookies

The Easiest (& Best!)

If you crush on peanut butter as much as I do, then these keto peanut butter cookies are an absolute must! Lightly crisp on the outside with a melt-in-your-mouth center, they’re honestly bound to have you swooning.

Plus, they’re super duper easy to whip up (just whisk!) and they freeze great (both baked and unbaked!).

The Deets

Classic (you know, sugar!) peanut butter cookies call for a 1:1:1 ratio. i.e. 1 egg for 1 cup peanut butter for 1 cup sugar.

But if you’ve been keto for a while, you’ll likely find one cup of sweetener to be sickeningly sweet. I generally do 1/2 cup… but with the latest batch I think you could even go to 1/3 cup, particularly if you’ve really been limiting your sweet intake.

Now, be sure to check out my ingredient suggestions to ensure you nail these guys!

The Peanut Butter

While I generally favor homemade nut butters, these keto peanut butter cookies are an exception as you really want that creamy smooth texture.

My suggestion is that you go for an unsweetened and salted variety (I really like the 365 brand from Whole Foods).

Whatever peanut butter you decide, just be sure it’s runny at room temperature (i.e. that its natural). You see, the ‘always solid’ varieties have generally had some of the natural fat drained or have added emulsifiers.

The Sweetener

You’ve got options here. I’ve tested them with Lakanto Golden (pictured), xylitol (non-corn though to avoid tummy troubles!) and allulose (just be sure to add 30% more as it’s less sweet!).

Just note that you’ll get slightly different results if you use erythritol vs xylitol or allulose. Least aftertaste will come from xylitol or allulose (though tbh the cooling effect from erythritol is minimal here!)… but the cookies will tend to spread more with xylitol and allulose (and take a few hours to set).

And last but not least, just like with our famous bakery-style chocolate chip cookies, I like to add a hint of blackstrap molasses for that burnt sugar kick (and needless to say, a tonne of umami). It’s just 0.15g net carbs a cookie, but it’s also totally optional!

If using xylitol, make sure to be careful if you have a pup (or kitty!) around the house, as it’s highly toxic to the little guys! 🐕

Ingredients

Instructions

  1. Preheat oven to 350°F/180°C and line a baking tray with parchment paper or a baking mat. 

  2. Add the sweetener, molasses (optional) and egg to a medium bowl and beat with an electric mixer (or whisk!) until light and fluffy, about 3 minutes. If using erythritol, keep in mind it won't dissolve completely and that's ok. 

  3. Mix in the vanilla extract, followed by the peanut butter. If you use erythritol, your mixture will be a bit crumbly, worry not! And also note that depending on the savory-ness of your peanut butter, you may need to add a touch of kosher salt at this point (see notes). 

  4. Scoop out the cookie dough, form into rounds and press down with a fork. Place in a prepared tray and freeze for 15 minutes prior to baking. 

  5. Bake for 12-14 minutes, until lightly golden and set. Feel free to sprinkle with flaky sea salt half way through!

  6. Allow to cool completely before digging (seriously!), and store in an airtight container for 3-4 days or in the freezer for up to 3 months. 

Recipe Notes

*Traditional peanut butter cookies use roughly 1 cup of sugar, but I find 1/2 cup to be more than enough (and you could even get away with using just 1/3 cup for more sensitive keto palates). Please see section on sweeteners for more deets! 

**Peanut butters vary a lot! Having said that, as long as you use a natural (unsweetened one!) you'll be fine. I really like the 365 unsweetened, salted one

***Whether you choose to add a bit of extra salt will depend on how savory your peanut butter is. And even though I use salted pb, I still add a bit more as I like my peanut butter cookies a bit more savory. 

And last but not least, please note that nutrition facts were calculated using natural peanut butter and the blackstrap molasses (remove 0.15g net carbs if opting out).

    Paola,
    You are a blessing and definitely missed when away! I make so many of your recipes. Glad to hear you are on the mend. You are in our thoughts and prayers.

  2. Deborah says:

    Paola, loved these ! Went rogue and ate the first one warm because I just couldn’t wait. Numbers two and three were fully cooled…but just barely.

    I only had Jiff Natural peanut butter in the house….and chunky style at that. When it was mixed (used a combo of xyletol …no pups in the house…and tagatose) it wasn’t quite firm enough to drop as mounds. I added about 1 1/2 -2 Tbs inulin powder (zero carbs plus gut healthy fiber) until it felt firm enough to scoop out. And ta da….worked GREAT. Did the salt flakes as your suggested….the only bad thing about that is it made them absolutely binge worthy.

    And let me add my well wishes to that of the others….so glad you are feeling better and on your way to recovery. We would miss you so very much if you were not to return.

    Paola:
    These cookies are amazingly delicious. Once again I have to hide them from myself or else my husband’s lunch will be cookie-less! Crispy outside and tender and chewy on the inside… since my scoop is small, I made 23 cookies and oops – now there are 21 cookies left. Fortunately, at just .6g net carbs apiece, I haven’t blown my budget for the day.

    I made a fat head pizza crust so, except for adding toppings and baking some more, I’m done in the kitchen….oh yeah, the sink is full of dirty cookware so off I go.

    Thank you for another great recipe Paola♥️

  4. Susie says:

    Hi Paola, I just made these and they are delicious. I actually ran out of peanut butter and didn’t want to make any, so I did 1/2 peanut butter and 1/2 almond butter and they are ver good.

  5. Rosie says:

    Made them with allulose and they’re AMAZING!!! I used 1/2 cup and might go up a bit more for the kiddos next time but for me they were perfectly sweet.

    On another note I saw in the comments that you took some time off for health? Is everything OK? We surely missed your terrific recipes and trust you’re on the mend, you’ll be in our prayers daily. The whole fam sends our love Paola and we’re so grateful for your delicious food that allows us to be sugar and grain free as 3 of us have Celiacs! You’re a blessing for the community 🙂

    • Paola van der Hulst says:

      Rosie that’s so wonderful to hear! I love allulose 🙂

      And re-my health, thank you so much for your prayers and good wishes. I am on the mend, but I suffered an injury to my sciatica back in June (and it got really bad in December)… essentially bed rest and wheelchair, but I’m slowly getting back on my feet! Big kiss!

    • Paola van der Hulst says:

      Awww thank you so much Holly, slowly but surely getting back on my feet ;)! Hope you love them! big kiss!

  6. JGreen says:

    I’ve tried a similar recipe for these using just plain erythritol and then ended up with PB cookies that have a “cooling effect” in the mouth (from the erythritol). Does this golden erythritol sweetener cause that same cooling effect?

    • Paola van der Hulst says:

      IMO with Lakanto it’s very slight (I’m suuuuper sensitive to it). If you were to go down to 1/3 cup I think it would disappear (you would lose some sweetness of course, could make up for it with a tad bit more monkfruit!

      Alternatively there’s always allulose (zero GI, pet friendly, no gastric upset and tastes just like sugar) xo!

  7. Gigi Casino says:

    Would love to try this using unsweetened natural almond or sunflower butter. Do you think it’ll be ok? Thanks!

  8. Raven says:

    Paola, do you think that the 365 brand of Almond Butter could be used in place of Peanut Butter, to make a variation of Almond Cookies? Thanks for your time!

    • Paola van der Hulst says:

      Hi Raven! I haven’t tried myself, but I don’t see why not! I feel like the almond cookies would be awesome with some chocolate chunks/chips 😉 xo!

    • Paola van der Hulst says:

      Awww thank you so much Claire! Slowly but surely getting better thank you!! ps. I missed you guys so much too! Life is def not the same without cooking, sharing and chatting with y’all 😉 big kiss!
