What Ingredients Are in Three Ingredient Peanut Butter Cookies?

This recipe keeps things as simple as possible. You only need three basic ingredients, but each one plays an important role.

You’ll need:

1 cup peanut butter
1 cup white sugar
1 egg

Ingredient Notes

Peanut butter is the star of the recipe, so use one you enjoy eating. Creamy peanut butter gives the cookies a smooth texture, while crunchy peanut butter can add little bits of nutty texture.

White sugar sweetens the cookies and helps them bake with lightly crisp edges. Since this recipe has so few ingredients, measuring the sugar correctly helps keep the texture balanced.

The egg holds the dough together and gives the cookies structure. Without it, the mixture would be too crumbly to shape and bake properly.

How to Make Three Ingredient Peanut Butter Cookies

Making these cookies couldn’t be more straightforward. You mix, roll, press, bake, and cool.

Preheat the Oven

Preheat the oven to 350 degrees F, or 175 degrees C.

Line baking sheets with parchment paper. This helps keep the cookies from sticking and makes cleanup easier.

Mix the Dough

Add the peanut butter, white sugar, and egg to a medium bowl.

Mix until the dough is smooth and fully combined. The mixture should look thick, soft, and easy to scoop.

Shape the Cookies

Roll the dough into 1-inch balls.

Place the dough balls about 1 inch apart on an ungreased baking sheet.

Flatten each cookie with a fork, making a criss-cross pattern on top. This classic peanut butter cookie design also helps the cookies bake evenly.

Bake the Cookies

Bake the cookies in the preheated oven until they are just barely brown on the bottoms, about 6 to 8 minutes.

Be careful not to overbake them. These cookies can become too crumbly if they cook too long.

Cool and Serve

Let the cookies cool briefly on the baking sheets before transferring them to a wire rack.

Once they are completely cooled, serve and enjoy.

Should You Chill the Cookie Dough?

If you have time, yes.

Chilling the dough before rolling it into balls can make it easier to handle and may help the cookies hold their shape better while baking. This step is optional, but it’s helpful if your dough feels soft or sticky.

Even 20 to 30 minutes in the refrigerator can make a difference.

How to Store Easy Peanut Butter Cookies

Allow the peanut butter cookies to cool completely before storing them.

Once cooled, transfer them to an airtight container or cookie jar. Store at room temperature for up to five days.

For the best texture, keep the container tightly sealed so the cookies don’t dry out.

Can You Freeze Easy Peanut Butter Cookies?

Yes, these cookies freeze well.

For the best results, freeze the dough balls before baking. Roll the dough into balls, place them on a baking sheet, and freeze until firm. Then transfer the frozen dough balls to a freezer-safe bag or container.

When you’re ready to enjoy the cookies, remove the dough balls from the freezer and bake according to the recipe.

What to Serve With Three Ingredient Peanut Butter Cookies

These cookies are simple, sweet, and perfect with classic pairings.

Serve them with a cold glass of milk, hot coffee, tea, hot chocolate, or vanilla ice cream. They also make a great lunchbox treat or quick dessert after dinner.

For a fun dessert plate, pair them with chocolate chips, sliced bananas, or a drizzle of melted chocolate.

Three Ingredient Peanut Butter Cookies Substitutions and Variations

One of the best things about this recipe is how easy it is to customize.

Use Crunchy Peanut Butter

If you like texture, use crunchy peanut butter instead of creamy. It adds little peanut pieces throughout the cookies.

Add Chocolate Chips

Stir in a small handful of chocolate chips for a chocolate-peanut butter version.

Add Vanilla

A splash of vanilla extract can add extra warmth and sweetness to the dough.

Sprinkle With Sugar

Before baking, sprinkle the tops with a little extra sugar for a sweet, lightly crisp finish.

Make Them Smaller

Roll smaller dough balls for bite-sized cookies. Just watch the baking time closely so they don’t overcook.
