3 Ingredient Peanut Butter Cookies
With the right combination of fat and sugar, all you need are three ingredients to make a decent cookie. These 3 Ingredient Peanut Butter Cookies will fool everyone into thinking you put a lot of time and effort into the batch. But, little will they know that it takes just a few minutes to mix the ingredients and bake these cookies. This is a great recipe for kids to make, too!
3 Ingredient Peanut Butter Cookies Recipe
The title of the name pretty much says it all–three ingredients is all you need to make peanut butter cookies! Plus, it’s a 1:1:1 ratio (1 cup peanut butter, 1 cup sugar, and 1 large egg) making it easy to remember!
- Peanut butter–I used creamy, but you could also use crunchy. Just stay away from the natural peanut butter.
- Granulated sugar–You could substitute brown sugar for a more butterscotch flavor to the cookie.
- Egg–room temperature
The science behind the ingredients makes this recipe work. The peanut butter is the fat that is so important when baking cookies. It gives the cookies the color, flavor, and crispness that most of us want in our cookies.
The sugar is important for tenderizing the cookie as well as sweetening the cookie. Sugar crystals also make room for the leavening agent to react and allow the dough to inflate. Speaking of a leavening agent, that brings us to the egg. The egg yolk has some fat in it to give the cookie a light texture and the egg white acts as the leavening agent to give the cookie a bit of volume.
How to Make 3 Ingredient Peanut Butter Cookies
This really is one of the simplest recipes out there. Simply combine the peanut butter, granulated sugar, and the egg in a bowl, stirring until all the ingredients are incorporated. Evenly spread out your scoops of cookie dough onto a parchment-lined baking sheet and bake them for 6-10 minutes at 350°F. The baking time depends on the size of your cookies.
I used a 3 tablespoon scoop for the best results, but size does vary, of course. If you want that traditional criss-cross pattern that peanut butter cookies are known for, just use a fork to press down on the cookies before baking them. After you remove the cookies from the oven, let them cool before enjoying them.
How to Store Peanut Butter Cookies
3 Ingredient Peanut Butter Cookies are best served warm, but you can keep them somewhat fresh by storing them in a plastic zip sealed bag at room temperature for up to six days. You can always add up to a half piece of bread in the bag with the cookies to keep them from getting too hard.
To freeze the cookies, let them cool completely before storing them in an airtight, freezer-safe container for up to three months.

Why can’t you use natural PB? Not enough preservatives?
“The salt and sugar from that regular peanut butter can add a lot of flavor to a recipe, and the thickness of the peanut butter translates into less spread for peanut butter cookies, for instance. Natural peanut butter is often unsalted, so you may need to add additional salt to a recipe.”
I can’t wait to try this recipe.
I looooooove pb cookies and you only use 3 items makes this so much easier.
Woo hoo hoo
I only have skippy natural, what happens if I use it?
I have used that, it worked great. 🙂
That’s the way my mom taught me to make peanut butter cookies love it
Can you use a substitute sugar ? I am diabetic.
I haven’t tested these with a sugar substitute so can’t say.

I made my peanut butter cookies with jiffy whips, Lakanto Golden Sugar (monkfruit brown sugar for those who can have sugar cane) an egg and vanilla. It was delicious!
Sounds wonderful! Love peanut butter (Jiff). I think maybe I can’t screw this recipe up! 🤣

You give cookies without sugar.
I’ve made this recipe many times! Always a hit! I always use natural pb, though, with no problems. I also recently used Swerve (a sugar substitute), and it was great.
can you substitute maple syrup for the sugar?
Hi, M.T.! I work with iambaker and am happy to help with questions. We have not tried using maple syrup in this recipe, so I can’t say how the cookies would turn out. Let us know if you try it, and have a great day!
