Over 10 years ago, I stumbled across this three-ingredient peanut butter cookie recipe in a little cookbook. I was in awe that 1 egg, peanut butter, and sugar could produce such a drool-worthy cookie. After trying them for the first time, my only regret was that I wish I had discovered this recipe much sooner!

In fact, I love them just as much as my super delicious Chewy Peanut Butter Brownies.

When it comes to baking, I am all about quick, and easy recipes. Sure, I love to get a little fancy once in a while, but for the most part, simplicity is key with three young children.


The only ingredients you’ll need to make 3 Ingredient Peanut Butter Cookies are 1 egg for binding the ingredients, traditional style peanut butter (not all natural), and white granulated sugar. That’s it!

You can use creamy or chunky peanut butter. I have made this recipe several times using either type of peanut butter and both bake up just fine. If you want a bit of crunch in your cookies, definitely use chunky peanut butter!

It’s also worth mentioning that these cookies are gluten-free! That makes them a perfect and quick dessert for people with gluten allergies! Most store-bought gluten-free cookies are higher priced than traditional cookies, so these are a blessing!

How to Make:

The process for making Three (3) Ingredient Peanut Butter Cookies can’t get any easier. After preheating your oven to 350 degrees Fahrenheit, grab a large bowl and add the peanut butter, sugar, and egg. Mix it together with a spoon or in an electric mixer until it’s well combined.

Once the batter is fully mixed, roll the dough into golf ball sized balls and place them on a parchment paper-lined baking sheet. The parchment paper will help prevent the cookies from sticking to the pan and make cleanup easier.

Here’s the most important part… Take a fork and press the cookies down until they’re about 3/8″ thick. Then turn the fork 90 degrees to make a crosshatch pattern on the top of the cookie dough. The cookies don’t spread on their own, so this step is important!

You’re now ready to place them in the oven to bake. Go ahead and place them on the center oven rack and bake them for 8-10 minutes until the edges look golden brown. Definitely check them after 8 minutes to make sure they’re not burning.

Allow them to fully cool, and enjoy your super easy three-ingredient peanut butter cookies!

These cookies will last for up to 3 days when placed in an airtight storage container at room temperature.


Freezing cookie dough is a great way to save time. The dough can be rolled into balls, placed on parchment-lined baking sheets, and then frozen for about an hour or two until solid.

Transfer the frozen dough balls by placing them in a freezer-safe container or bag. When you want some cookies pull out as many individual pieces as needed from the bag/container and bake with 1 minute of added time.

    These cookies are perfect to make rich Peanut Butter Blossoms (where you put a Hershey’s kiss in the middle when they come out of the oven).

    I usually use 1/3 cup each of brown sugar, powdered sugar, and regular white sugar because it’s a a very slightly different taste and texture. I also will add some vanilla extract if I remember it. It doesn’t really matter, the recipe is great as is.

    Thanks for sharing this great recipe!

    Is there no flour in the Recipe?

      There is no flour at all. I made these cookies for my mom who had celiac disease(so NO gluten) and she loved them. Sometimes added m&Ms or mini chocolate chips.
