3-Ingredient Peanut Butter Cookies Ingredients
For the Cookies
- Peanut Butter – Use smooth or crunchy for different textures; it’s the star of 3-Ingredient Peanut Butter Cookies’ rich flavor.
- Granulated Sugar – Balances peanut butter’s natural saltiness and creates that perfect crispy edge.
- Egg – Acts as a binder to hold the cookie dough together with a tender, chewy finish.
How to Make 3-Ingredient Peanut Butter Cookies
For the Cookies:
- Preheat your oven to 350°F (175°C) for at least 10 minutes. Line a large baking sheet with parchment paper for easy cleanup and even, golden-brown edges.
- Combine peanut butter, granulated sugar, and one egg in a medium mixing bowl. Stir vigorously until the dough is smooth, creamy, and free of lumps—about 2 minutes.
- Shape dough into 1-inch balls using a small cookie scoop or spoon. Roll each between lightly floured hands for smooth surfaces, then place balls at least 2 inches apart.
- Flatten each dough ball with the back of a fork, pressing in a crisscross pattern. Aim for about a 1/2-inch thickness so cookies bake evenly and remain chewy.
- Bake on the center oven rack at 350°F (175°C) for 10–12 minutes, or until edges develop a golden-brown hue. Centers will seem soft but will set as they cool.
- Cool cookies on the baking sheet for about 2 minutes to firm up. Then transfer gently to a wire rack and cool completely for the best chewy-yet-crisp texture.
Optional: Sprinkle flaky sea salt atop warm cookies for delightful flavor contrast.

- Don’t overbake: Remove cookies when edges turn golden but centers look slightly soft to keep that chewy texture.
- Press cookie dough gently: Too much force will make cookies thin and crispy instead of tender and chewy.

What kind of peanut butter works best for 3-Ingredient Peanut Butter Cookies?
Smooth peanut butter is ideal for a silky dough, but crunchy peanut butter adds wonderful texture and nutty bursts. Either works wonderfully—just avoid natural versions that separate unless you stir them well first.
How long can I store these peanut butter cookies at room temperature?

Why did my cookies turn out too dry or crumbly?
This usually happens if the cookies are overbaked or if the dough was too dry. Make sure to remove cookies from the oven as soon as the edges turn golden and centers still look slightly soft.

Are these cookies safe for people with peanut allergies or pets?
These cookies contain peanut butter, so definitely avoid serving them to anyone with peanut allergies or pets sensitive to nuts.
