Flourless peanut butter cookies are the perfect sweet treat for anyone, including those on a keto or gluten free diet. This easy cookie recipe uses 3 ingredients and 2 net carbs per cookie!
This is seriously the easiest and best gluten free peanut butter cookie recipe I have ever made. Plus, they are incredibly quick to make, keto-friendly, and dairy free too.
I’m not joking… with 3 simple ingredients, you can bake an entire batch in less than 25 minutes.
Ingredients for this gluten free peanut butter cookie recipe:
- Peanut butter – Using creamy peanut butter is my recommendation. Not only does this make mixing the cookie dough easier, but it also gives the flourless peanut butter cookies a silky smooth texture.
This being said, if you want to use chunky peanut butter, it will work just fine. Also, if you have peanut allergies, feel free to use a different type of nut butter.
NOTE: Since this recipe uses so much peanut butter, feel free to use the cheapest peanut butter you can find. However, I use peanut butter with the cleanest ingredients, no sugar, and the few carbs. - Sugar– To keep these PB Cookies keto and diabetic friendly use your favorite white sugar substitute. I prefer this one, but use your favorite. Otherwise, simple granulated white sugar is what you’ll want to use.
- Egg– For egg-free peanut butter cookies, feel free to use a flax egg or an egg replacer. I’ve had hit or miss results with egg substitutes. Try it if you need to and let me know how it works for you.
How to make flourless peanut butter cookies
Seriously, you won’t believe how easy these cookies are to make. You don’t even need an electric mixer!
Just toss the ingredients into a large bowl and use a mixing spatula or wooden spoon to combine them. Even young kids can make these cookies with no problem.
When the ingredients become creamy and smooth, drop the dough by teaspoonfuls onto cookie sheets.
To make the ridges on the top of peanut butter cookies:
- Dip the tines of a fork into a little bit of water, then into your sugar of choice.
- Gently press the fork down onto each ball of cookie dough. As a result, it flattens the cookie, too.
How to Store and Freeze Cookies
Store the gf peanut butter cookies in an airtight container at room temperature. They will keep well for 5 to 7 days.
The cookies freeze beautifully! Just be sure to cool them completely before transferring to freezer-safe containers or Ziploc bags. They keep well frozen for about 3 months. After that, they tend to develop freezer burn.
Oh, and to help prevent them from sticking together, I like to separate the cookies with squares of parchment or wax paper.
This cookie recipe is the inspiration for my Halloween Witches Brooms Cookies and also my Flourless Nutella Cookies! And if you love these, you’re gonna love my Coconut Chocolate Chip Oatmeal Cookies.
Flourless Peanut Butter Cookies
I don't think there is an easier keto friendly & gluten free cookie recipe than these 3-ingredient Flourless Peanut Butter Cookies.
Ingredients
- 1 cup Peanut butter (creamy or crunchy)
- 1 cup sugar (granulated sugar substitute or regular sugar)
- 1 Egg
Instructions
- Preheat oven to 350 degrees F. Line 2 cookie sheets with parchment paper, or use non-stick baking mats.
- Add all ingredients to a bowl and use a mixing spatula or wooden spoon to combine.
- Drop by teaspoonfuls onto greased cookie sheets. Use a fork dipped into sugar to press into cookies.
- Bake for 10-12 minutes, being sure not to brown them. Then remove pan from oven. Allow cookies to cool for 3 minutes on the cookie sheets, then transfer the cookies to a wire rack to cool completely.
Notes
Accommodating Allergies
- To make it the lowest carb possible: check label for the lowest carb peanut butter at your store. Pick one without added sugar and oils.
- This gluten free peanut butter cookie recipe calls for a lot of peanut butter. Therefore, feel free to use the cheapest peanut butter you can find if you aren't worried about carb count.
- To accommodate peanut allergies, feel free to use another type of nut butter.
- To keep the calories and carb count lower, use an equal amount of any cup-for-cup sugar free substitute. I like this one.

For those who have asked about sugar substitutes, Swerve measures cup for cup and works great.
is there any substitutions i could use for the sugar to make them healthy?? Like would agave nectar work?
I don’t think so Fatima! With so few ingredients you really need the structure that the sugar provides. ~w
Thanks for the recipe!!!!! My hubby can’t have flour, so when I saw this recipe I made them right away. We both loved them. He’s Gluten Free
That’s so great to hear Myrna. Glad y’all loved them. w-
Every time I’ve made these they turn out great, just like the real version! Except when I burn them :/ So simple and no one would ever know it is even GF thanks for sharing
I’ve made these a couple of times and the mixture is very crumbly and I have to use my hands to try to make them into rounds. What am I doing wrong? I use an electric hand mixer and no substitutions.
What kind if peanut butter are you using? What size eggs? Just curious so I can help figure out what’s going on.
could I substitutute almond butter or cashew butter?
I don’t see why you couldn’t make that substitution, but I haven’t tried it. Let me know if you try it and how it works out.
will do thanks for the prompt reply
I’d forgotten all about this recipe, I probably haven’t made them in 20yrs but they always come out perfect! I use super chunky peanut butter and they were wonderful, I’m going to make some tonight!
I haven’t tried with chunky PB Rose…might just have to give it a try!
Wonder if using stevia would work. May have to make a quarter recipe to try!
Not sure…haven’t tried it. Let me know how it works if you do give it a shot. 🙂
We shape them like lady fingers and dip half of them in chocolate…or use a whisk and drizzle chocolate over them, tastes just like a Reese’s.
Brilliant idea Ashley!!!!
Just popped these in the oven .mmm can’t wait. 🙂
I KNOW these cookies LOL and love them!!
My kids and I made this together this evening. I was a little sceptical at first because with the lack of flour, I figured these cookies would lose all fluffiness. But no! Surprisingly, these cookies were perfect. They were just a tad crip on the bottom and so chewy and peanut-buttery in the center. I LOVE peanut butter cookies, and the peanut flavor was strikingly stronger in this recipe than any other I’ve tried….which is a great thing of course! My husband is not a peanut butter enthusiast like muah, (more of a chocolate chip kind of guy), and he LOVED them! Thank you so much for sharing this recipe. This is definitely the easiest, fastest peanut butter cookie recipe I have found, and will be one to stick to when that craving hits again!
I used to make these often too!
I had forgotten about these! I used to make them all the time but they somehow fell by the wayside. They're fantastic! Thanks for the reminder. :o)
Yummy! I love that they are flourless! Thanks for sharing your yummy recipe.
As a gluten free family, we make these constantly and LOVE them!
That almost just as easy as opening up a package of Betty Crocker ones…haha! I love pb cookies and always forget about them!
