Introduction

These classic 3-ingredient peanut butter cookies are wonderfully simple, delicious, and perfect when you want a homemade treat without a long ingredient list. With just peanut butter, sugar, and an egg, you can create cookies that are crisp around the edges, soft in the center, and packed with rich peanut butter flavor.

They are ideal for afternoon tea, lunchboxes, family gatherings, bake sales, or simply satisfying a sweet craving. The recipe is also easy enough for beginner bakers and can be prepared in just a few minutes.

Ingredients

Makes approximately 25 cookies.

• 1 cup peanut butter, approximately 240 g
• 1/2 cup granulated sugar, approximately 100 g
• 1 large egg

Optional additions

The three ingredients above are all you need, but you can add a little extra flavor if desired:

• 1 teaspoon vanilla extract
• 1/4 teaspoon salt, especially if using unsalted peanut butter
• A small handful of chocolate chips
• A sprinkle of granulated sugar for the tops
• Crushed peanuts for extra texture

Method

1. Prepare the oven

Preheat your oven to 175°C (350°F). Line a large baking sheet with parchment paper or lightly grease it.

2. Make the cookie dough

Place the peanut butter, sugar, and egg in a mixing bowl.

Using a wooden spoon, spatula, or electric mixer, mix everything together until thoroughly combined. The mixture should form a soft, slightly sticky dough.

If you are adding vanilla or salt, mix it in at this stage.

3. Shape the cookies

Using a tablespoon or small cookie scoop, portion the dough into approximately 25 equal pieces.

Roll each portion gently between your hands to form a ball. Place the balls on the prepared baking sheet, leaving enough space between them for slight spreading.

4. Create the classic peanut butter pattern

Using a fork, gently press down on each cookie ball.

Press once vertically and once horizontally to create the traditional crisscross pattern. Do not press so hard that the cookie becomes completely flat.

5. Bake

Place the baking sheet in the preheated oven.

Bake for approximately 8 to 12 minutes, depending on the size of your cookies and your oven.

The edges should look set while the centers may still appear slightly soft. Avoid overbaking, because the cookies will continue to firm up as they cool.

6. Cool

Allow the cookies to remain on the baking sheet for about 5 minutes after removing them from the oven.

Then carefully transfer them to a wire rack and allow them to cool completely.

They become firmer as they cool while retaining a pleasant softness in the center.

Important Baking Tips

Choose the right peanut butter

For the most reliable results, regular commercial creamy or crunchy peanut butter works well. Natural peanut butter can sometimes separate and contain more oil, which may affect the texture.

If using natural peanut butter, stir it extremely well before measuring.

Do not overmix

Once the ingredients are combined into a uniform dough, stop mixing. Overworking the mixture is unnecessary.

Watch the baking time

Peanut butter cookies can go from perfectly baked to dry quite quickly. Remove them when the edges are set and the centers still look slightly soft.

Let them cool

Freshly baked cookies can be delicate. Giving them several minutes on the baking sheet allows them to firm up before transferring them.

The History of Peanut Butter Cookies

Peanut butter cookies became popular in the United States during the late 19th and early 20th centuries as peanut butter became increasingly common in American kitchens.

Early peanut butter cookie recipes appeared in American cookbooks and magazines, and the cookies became particularly recognizable because of the fork-made crisscross pattern.

The pattern is more than decoration. Pressing the dough with a fork helps flatten the relatively dense cookie dough so that it bakes more evenly.

Over time, countless variations developed, including recipes containing flour, butter, brown sugar, vanilla, oats, chocolate, and other ingredients. The three-ingredient version remains popular because of its simplicity.

Formation and Texture

The formation of these cookies is remarkably straightforward.

The peanut butter provides the characteristic nutty flavor and much of the cookie’s fat and structure. The sugar contributes sweetness and helps create lightly crisp edges. The egg binds everything together and provides additional structure.

When the cookies bake, the heat transforms the soft dough into a firm cookie while allowing the peanut butter flavor to become more pronounced.

The finished cookies should have lightly crisp edges with a tender, chewy center.

Variations

Chocolate Peanut Butter Cookies

Add 1/2 cup chocolate chips to the dough before shaping.

Crunchy Peanut Butter Cookies

Use crunchy peanut butter instead of creamy peanut butter for pieces of roasted peanuts throughout the cookies.

Vanilla Peanut Butter Cookies

Add 1 teaspoon vanilla extract for a slightly sweeter and more aromatic flavor.

Salted Peanut Butter Cookies

Sprinkle a very small amount of flaky salt over the cookies immediately after baking.

Sugar-Coated Cookies

Before placing the dough balls on the baking sheet, gently roll them in granulated sugar for a slightly crisp exterior.

Storage

Once completely cooled, store the cookies in an airtight container at room temperature.

They are best enjoyed within several days for their freshest texture.

For longer storage, the baked cookies can be frozen in a well-sealed freezer container. Allow them to thaw at room temperature before serving.

You can also freeze portions of the unbaked dough. Shape the dough into balls, freeze them on a tray until firm, then transfer them to a freezer-safe container. When ready to bake, place the frozen dough balls on a baking sheet, make the fork pattern, and bake until done, allowing a little extra baking time if necessary.

Serving Suggestions

These peanut butter cookies are wonderful served with:

• A cup of tea
• Coffee
• Cold milk
• Hot chocolate
• Vanilla ice cream
• Fresh berries
• Chocolate sauce
• A glass of cold milk and a warm cookie straight from the oven

They also make a simple homemade gift when arranged in a decorative tin or wrapped in food-safe packaging.
