Making 3-Ingredient Peanut Butter Cookies is incredibly simple. Follow these steps for perfect results:

1. Preheat Your Oven: Preheat your oven to 350°F (175°C) and prepare a baking sheet by lining it with parchment paper.
2. Mix Ingredients: In a mixing bowl, combine the peanut butter, sugar, and egg. Stir until fully blended and smooth.
3. Form Cookies: Using a tablespoon or cookie scoop, drop rounded balls of dough onto the prepared baking sheet, spacing them about 2 inches apart.
4. Flatten: Use a fork to gently press down on each cookie, creating a crisscross pattern on the tops.
5. Bake: Place the baking sheet in the preheated oven and bake for 10-12 minutes, or until the edges are lightly golden.
6. Cool: Remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.

These steps are all you need to create delicious, chewy 3-Ingredient Peanut Butter Cookies!
