How to Make 3-Ingredient Peanut Butter Cookies Step by Step

Step 1: Prepare the Oven

Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cleanup.

Step 2: Mix the Dough

In a mixing bowl, stir together the peanut butter, granulated sugar, and egg until smooth and fully combined.

The dough will be soft and slightly sticky.

Step 3: Shape the Cookies

Roll the dough into 1-inch balls and place them on the prepared baking sheet, leaving about 2 inches of space between each cookie.

Step 4: Create the Classic Crisscross Pattern

Use a fork to gently press down on each dough ball, making a crisscross pattern on top.

Step 5: Bake

Bake the cookies for 10 to 12 minutes, or until the edges are lightly golden.

Step 6: Cool and Serve

Allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack.

Enjoy them warm or at room temperature.
