Cookies as easy as 1-2-3-4— peanut butter, sugar, baking soda, and an egg. That’s it! These tasty peanut butter cookies are naturally gluten-free, but if I didn’t tell you they were flourless you might not have guessed.

My boys used to make these easy peanut butter cookies with me all the time, and now they’re old enough that they don’t even need my help anymore (that’s how EASY they are!). You won’t find a simpler cookie recipe, and kids and adults are sure to love them! Psst, I also have a flourless peanut butter chocolate chip cookie recipe variation, if that’s more your thing.

These were so delicious, and so easy. I loved that they weren’t overpoweringly sweet. I used Skippy natural peanut butter. I rolled the cookies in coarse sugar before baking. Brought them to my sister after she had a baby, and they were perfect! ⭐⭐⭐⭐⭐” —from reader Lisa

Yes, just 4 ingredients!

Here’s everything you need to make this easy peanut butter cookie recipe (full recipe at the end of this article):

baking tip:What is the best peanut butter for baking?

Many recipes will specify, and it’s always best to follow the recipe!

Crunchy or creamy? In many cases the decision is ultimately up to you, though creamy peanut butter is slightly more preferred for a lighter, softer end product. Chunky peanut butter can possibly create drier, more crumbly baked goods.

Traditional or natural-style? Unless stated otherwise, use traditional-processed peanut butter (think Jif, Skippy, etc.) instead of natural peanut butter for the best texture. It is possible to substitute natural-style peanut butter in many recipes, just know the results may be different.

How to make these easy peanut butter cookies

  1. Mix ingredients in a bowl, no mixer required! Use a spatula or wooden spoon to combine the peanut butter, brown sugar, egg and baking soda to make a uniform dough.
  2. Portion and flatten with a fork. I like to use a cookie scoop to make sure they’re all the same size, then roll dough into rounds. Make a criss-cross pattern with your fork to flatten the cookie dough balls slightly.
  3. Bake. Place on a baking sheet pan lined with parchment paper and bake in a 350°F oven for about 8-10 minutes.
  4. Enjoy! And watch how fast these cookies disappear.

  • Natural-style peanut butter vs traditional processed peanut butter: I recommend traditional peanut butter because it contains additional oil which will keep the cookies moist. If you use natural-style peanut butter, just know that your cookie may be a bit more dry and crisp.
  • Do not over bake! These cookies are done when they look slightly puffed with some cracks. If you wait till the edges are golden brown, the cookies will lose their soft texture and instead will be crisp and crumbly.
  • Cookie dough freezes very well. And it’s my favorite hack for fresh cookies whenever I want them. Simply take them out of the freezer, place on a sheet pan, and let them thaw a bit while the oven preheats.
