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.

Bake for about 5 minutes, or until cookies reach your desired doneness.

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.

  1. 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.

    1. 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!

  2. How can a cookie with only 3 ingredients be this good? dont know, dont care, they are excellent, double the recipe

  3. Hello.
    I am interested to bake biscuits, cabin crackers we call it here.
    Would you have a recipe for corn flour biscuits?

  4. Made these tonight they were awesome! So easy and quick. I also love that it’s a small batch recipe, like so many of yours are, you get to finish them before you’re sick of them.

  5. Well I hope you’re happy, you have created pb cookie junkies. This is the best pb cookie and by far the easiest I’ve ever made. My son just offered to go and get more pb!

  6. add a 4th ingredient: a chocolate kiss or rosette pressed into the middle makes an even more delicious and special cookie.
