3 Ingredient Peanut Butter Cookies use only peanut butter, brown sugar, and an egg. That’s it. Chocolate chips are a great addition but are totally optional.
You know how some recipes just seem wrong? Your friend jots down a recipe and you look at it and think, “Really, Mary? I know you forgot something, girl.” Or you hit up a blog and wonder why chicken isn’t listed in the chicken noodle soup*.”
*This one is probably just an oversight. Send the blogger a nice note. They will die when they read it and then correct the recipe asap.
That’s how I felt when I first saw a recipe for flourless peanut butter cookies. If you’re not familiar with it, the recipe goes like this: combine peanut butter, an egg, and some sugar. That’s it.
Looks wrong, right?
The first time I made it, I was pretty sure the recipe wouldn’t work. In fact, I think I made the recipe with that attitude. “Let’s see what all this ruckus is about!” I mean, c’mon, peanut butter, an egg, and some sugar? My baker’s sense told me that the peanut butter brings fat, the egg gives us structure. but the sugar stumped me. In baking, sugar is a liquefier. That means that when it gets hot, it turns to liquid. Too much sugar in a recipe and cookies can spread all over the place.
Without a little flour to hold the sugar in check, I really thought I’d have puddles of peanut butter on my baking sheet.
I grabbed my bowl, stirred everything together, and, well, the first surprise hit. The dough looked like…dough. It was maybe a little softer than regular cookie dough but it scooped out well and held the traditional fork imprints nicely.
As the first pan baked, I switched on the oven light–fully expecting to see puddles. That never happened. The egg did it’s thing, lifting the dough ever so slightly, and holding everything together.
After the cookies cooled, they looked perfect. I took a bite. Oh my! They tasted like the most peanut buttery-peanut butter cookies I’d ever eaten. They were soft with just enough crunch on the edge to make you feel like you were eating a cookie and not a power bar.
But…I wasn’t happy.
As much as I liked the cookies, I wanted to love them. The recipe I followed used a full cup of granulated sugar. This made for really sweet peanut butter cookies. Since granulated sugar only brings sweetness and not flavor, I decided to swap it for dark brown sugar. I figured a little molasses flavor would pair nicely with the peanut butter.
Then, since I like crunch, I used natural crunchy peanut butter instead of creamy. Because to me crunchy > creamy. Obviously this one is just a preference. But I do encourage you to use natural peanut butter. The fat in traditional peanut butter, usually a shortening-type fat, gives the cookies an oddly greasy and almost plastic texture. For fun, I stirred chocolate chips into half the batch. I don’t think I need to explain to you that peanut butter and chocolate are awesome together. I mean, you’re reading a food blog. You know this.
The cookies were exactly what I wanted. Deeply flavorful, crunchy, and full of peanut flavor
If you love peanut butter, add this recipe to your must-try list. It’s that good. And don’t I wish that finding out you were wrong always tasted this good.

Thank you for all the explanation that came with this recipe. I wanted to try brown sugar instead of granulated to get more flavor. You did it for me and helped me understand the why’s and the how’s. I will also follow your suggestion for natural, crunchy peanut butter. I look forward to my next batch of peanut butter cookies!
Dawne says
I’ve been using this the recipe for a long time. I use store brand peanut butter and half a cup of organic sugar and half a cup of turbanado sugar. THere was a fourth ingredient 1 tsp vanilla i have left that out as it didn’t make a difference in the flavor.
Glen McPherson Jr. says
Along with the Last Woman who had the same question I have wondered for a while now…Thank you for that explanation..They turned out Phenominal!!
MS. Robbin Dilger says
I have carpool tunnel very bad in both hands. I so love to bake and It has come down to how much i can do.
I accidentally came across your recipe and am getting ready to put them into the oven. Brb. Lol
The verdict is in… Next time fix a double batch…
This makes me so happy as I can bake these.
Ps… I wanted choc. chips and they didn’t. So I spilt the dough in half.. ????☺????
Is there anymore recipes like this one??
Pamela Simpkins says
Really want to try these today! Can I use Jif peanut butter?
Elizabeth says
Sure!
Heidi says
I was skeptical but these delivered . Best peanut butter cookies I have ever made and eaten!
M. GB says
Amazing! Brought me back to childhood. *Added some homemade jam, rather than sugar, at the end of step 3.
Cheryl says
I made these with regular Kroger brand smooth peanut butter, after reading that natural PB made them too oily. I used brown sugar, a little less than a full cup, and added a teaspoon of vanilla extract, which was in another variation of this recipe. The dough was a bit loose so I popped it into the freezer while the oven preheated. This helped immensely. They came out great. I will add chocolate chips and/or peanut butter chips next time, just to add something extra. All in all, a great, easy recipe for an inexpensive dessert, especially for peanut butter lovers. They were really good.
Mary says
I have used this recipe for yrs. Love it. It’s a big hit with hubby and grandkid’s
Geneva Sucomba says
This worked better than I expected! They taste wonderful but don’t seem to be great for dunking in milk. My kinda fall apart, nothing really binding things together I suppose. The texture is more sand-y than cookie-y. Maybe a sprinkle of flour would help? All in all though, a nice easy recipe that accomplished its goal: getting sweet things in my tum ASAP ^_^
Misty Hatfield says
I was wanting to make some and was out of sugar so decided if brown sugar would work I googled it as I do a lot of stuff and seen how yours was made so I made some but I didntblet my dough set 10 mins I hope it didn’t hurt anything we will see shortly when their ready to eat thank you
Lillian Miller says
I absolutely love these cookies but I would like to know the serving size and the calories per serving size
Elizabeth says
I’m not sure of the calories. Sorry!
Tiff John's says
Is this on cookie recipe for keto low carb he looks good n can’t wait to try them thanks Tiff
Lynzie says
I used two eggs to make them gooey… and just Jif Peanut butter. And then scooped out 24 cookies. The calculations I came up with are only 18 calories per cookie??
Lynzie says
Okay I commented on this a minute ago with the wrong number lol I used light brown sugar, 2 eggs and a cup of Jif.. 24 cookies per batch. 91 cal per cookie
Brye says
Sounds delicious! Can I add oatmeal to this recipe?
Elizabeth says
Hmmm…I don’t know how oatmeal would do in this recipe. Sorry!
Robin Zebleckis says
Can I use light brown sugar if I dont have dark?
Elizabeth says
Yes! That will work!
Diana says
Could I use coconut sugar?
Elizabeth says
I haven’t tested the recipe with coconut sugar. Sorry!
Connie Congemi says
I tried this recipe but added quick cook oatmeal, and they turned out good. Had to cook a little longer because I didnt smash down like regular peanut butter cookies.
Mrs. Lovely says
What can I do to make sure the cookies are soft after cooling down?
Elizabeth says
These cookies aren’t soft, I’m afraid. Due to the lack of flour, they’re a bit crisp. I’ll work on a soft peanut butter cookie recipe. That sounds good!
Dee says
Can I use sunflower seed butter instead of peanut butter?
Elizabeth says
Absolutely!
Marissa K says
I just tried this recipe with light brown sugar and this was delicious. I couldn’t believe that they came out as good as they did. I put them in at 350 for 10 minutes and they are crispy on the outside but nice and soft on the inside. Definitely would make again.
Devon says
I had a sweet tooth real late at night and didn’t have any vanilla extract, cocoa, or much flour, and this recipe saved me! These turned out way better than I expected.
I used chunky peanut butter and half granulate sugar/half brown sugar (because I didn’t have enough brown sugar.)
12 minutes at 350 was a perfect recommendation. The middles were gooey and the outsides perfectly crunchy. ????????made 14 cookies. Great and simple recipe. Thank you!! ❤️❤️
Erica says
Love love love this recipe. Having to go to food banks you sometimes end up with lots of peanut butter & no jelly!! This recipe is great for snacks or dessert!! Add coconut & different flavored chips when they are given!! Kids I’ve to help make. Thank you for sharing this recipe!!♥️
Ashley says
Can this dough be frozen ahead of time?
Elizabeth says
Yes. The dough freezes well.
Julie Burdette says
I love these cookies but always add a teaspoon of soda. Makes them puff up. I could eat my weight in them!!
Robin Gore says
These are 1 of my Must make for Christmas, and my go to recipe whenever looking for something sweet and delicious. I’ve made with just regular sugar and I’ve doubled the recipe and used regular sugar and brown sugar in even amounts and they came out Super Yummy. I also sometimes dip my girl in powered sugar when making the cross marks on top of cookies. Time to bake some cookies!!!!
Robin Gore says
Oops just made a comment and somehow a word appeared wrong. I meant to say, I sometimes dip my fork in Powered Sugar when making crisscross marks on top of cookies! Love this site!!!
Patty says
I saw a recipe like this, but it called for some vanilla, baking soda and salt. I made these tonight, using chocolate chips and coarse sea salt. Oh my goodness! The chocolate chips and brown sugar with crunchy crystals of salt are amazing!
Elizabeth says
This is now my go-to recipe. I’m a single, stay-at-home mom to 2-year-old twin boys, and when it comes to baking (for us or anyone/anything else), it’s pretty much impossible. Everything takes too much prep time, etc., for me to get it all done in their half-hour long naps, and when they’re awake, they’re climbing on counters and chairs, no matter how, or how many times, I try to stop them. This recipe is so quick and easy to just throw together and whip up. Aside from the amount of sugar, they’re a healthy snack, and either way, they’re filled with protein… and they taste *amazing*!! I am going to experiment with ways to cut down on the sugar. I’m a Beachbody coach, and I use our nutritional supplement, Shakeology, every day, but while thinking of ways to cut down on the sugar in this recipe, I thought that maybe I could try the Shakeo in place of some of the sugar. I used a full scoop of Shakeo (I’ve tried it with chocolate, café latte, and strawberry – all came out tasting *incredible*) and only 1/4 cup of sugar. They came out *so* well, though just *slightly* dry. Next, I’m going to try to figure out how it works with less sugar and no substitutions to make it easier for people who don’t have Shakeology sitting around their houses!
Seriously, though… I love this recipe. It’s my new favorite.
