Pin ItI love baking all kinds of cookies (I am a cookie monster), but when I need an EASY recipe, I always turn to my 3 Ingredient Peanut Butter Cookies.
I have been making these cookies for years and I still can’t believe they turn out, ha! There really are only THREE ingredients and they turn out every single time.
If you love peanut butter, you are going to fall in love with these cookies. They have a rich peanut butter flavor, they are crisp around the edges, and soft and chewy in the center. Everything you want in a peanut butter cookie!
The cookies are gluten-free, dairy-free, and SO delicious!

3 Simple Ingredients
That’s right, you only need THREE ingredients!
- Peanut Butter– use creamy butter, Skippy and Jiff are classic brands. Don’t use crunchy peanut butter or reduced fat peanut butter, the cookies will be dry and crumbly.
- Sugar– basic white sugar does the trick!
- Egg– to add moisture and bind the ingredients together.
How to Make 3 Ingredient Peanut Butter Cookies
- Preheat the oven and line a large baking sheet with parchment paper or a Silpat baking mat.
- In a large bowl, mix peanut butter, sugar, and egg together until creamy and smooth. You can use a stand mixer, hand mixer, or mix by hand.
- Scoop the cookie dough into balls, about 1 tablespoon per cookie, and place on prepared baking sheet. Flatten each ball with the back of a fork, making a criss-cross pattern. The cookies don’t spread in the oven, so you can put them close together on the baking sheet.
- Bake for 8 to 10 minutes or until edges are slightly golden. Don’t over bake. If it’s your first time making the recipe, check the cookies early to be safe. The cookies should be slightly golden around the edges, but still soft in the center. They will set up as they cool.
- Remove from the oven and let the cookies cool on the baking sheet for 3 minutes. Transfer to a cooling rack to cool completely.
Customize the Cookies
These are technically 3 ingredient cookies, BUT if you want play around, you can add the following ingredients. They won’t be 3 ingredient cookies anymore, but still really easy!
- Vanilla extract– add a splash of vanilla extract.
- Salt– add a pinch of salt to the cookie dough. You can also finish the cookies with flaky sea salt.
- Chocolate– stir in a handful of chocolate chips or chocolate chunks.
- Candy– add some color to the cookies by stirring in Reese’s Pieces or M&M’s!
- Sugar coating– you can roll the cookies in granulated sugar before baking if you want to add a little extra sweetness!
How to Store
Store the cooled cookies in an airtight container on the counter for up to 4 days.
You can also freeze the baked cookies for up to 3 months. Make sure you freeze them in a freezer container or freezer bag (with the air removed) to keep them fresh.
You can also freeze the cookie dough. Roll the dough into balls and place on a baking sheet or tray. Put in the freezer until the balls are firm. Transfer the balls to a freezer container or bag and freeze for up to 3 months. When ready to bake, remove from the oven and add a couple of minutes to the baking time.
FAQ
Yes! They are flourless peanut butter cookies so they are naturally gluten-free.
I think the cookies have the best texture when I use a classic brand like Skippy or Jiff. If you want to try natural peanut butter, make sure the peanut butter is stirred really well and drippy, not dry.
You probably over baked the cookies. Check the cookies at 8 minutes to be safe. The cookies should be slightly golden brown around the edges, but still light in color and soft in the center. The cookies will finish baking as they cool on the baking sheet.
The fork marks in the cookie dough balls actually make them bake more evenly. The fork marks also give the peanut butter cookies a classic look.
