This 3-ingredient peanut butter cookie recipe is insanely good

Although peanut butter itself was first made by the Inca hundreds of years ago, it wasn’t until the early 1900s that peanut butter became an ingredient for cookies. These cookies were met with so much acclaim in the United States that they now have an official holiday: National Peanut Butter Cookie Day is celebrated each year on June 12th. 

As one of the easier classic cookies to make, even the most complicated peanut butter cookie has only a handful of ingredients. But, for novice bakers or those baking with younger kids, sometimes even a handful of ingredients can be too many. That’s why we went on the hunt for a super easy — yet really yummy — cookie recipe that virtually anyone can make. With just three ingredients, you can create the most delectable dessert, starring everyone’s favorite nut butter spread. 

The very best recipe for 3-ingredient peanut butter cookies

Kids love baking, but some recipes might have too many steps or ingredients for them to follow. If you’re looking for a simply delicious cookie recipe for beginners and accomplished bakers alike, this three-ingredient peanut butter cookie is it!

It’s a 1, 1, 1, ingredient list:

  • 1 cup peanut butter
  • 1 cup white sugar
  • 1 egg


  • While your oven is preheating to 350°F, line your cookie sheets with parchment paper. 
  • In a medium-sized bowl, combine the peanut butter, sugar, and egg and mix until smooth. Drop spoonfuls of dough onto the cookie sheet. 
  • To get that trademark criss-cross pattern on your peanut butter cookies, use a fork to press down on the dropped dough. Press down twice: once horizontally and once vertically. For an added touch of sweetness, top with a light sprinkling of granulated sugar before popping into the oven for 6-8 minutes. 

These cookies are best when soft and chewy. To make sure that your cookies have the proper consistency, do not overbake. Instead, bake them until they are just barely brown on the bottom. 

The crisscross marks are there for more than just aesthetics. Peanut butter cookies are denser than many other types of cookies, and pressing them with a fork flattens the dough so it bakes more evenly. 

How to store homemade peanut butter cookies

To properly store peanut butter cookies, make sure they are 100% cool before placing them in the container, otherwise, they could end up producing steam inside the container and you’ll be left with peanut butter cookie crumble. For best results, store your cookies in an airtight container at room temperature for up to a week. Pro tip: Skip those countertop cookie jars. Although they look cute, they allow cookies to get stale pretty quickly. 

If your cookies start to become less soft ’n chewy after a few days, stick a piece of bread inside the container. The cookies will absorb moisture from the bread to make them soft and chewy all over again.
