In a mixing bowl, combine the creamy peanut butter and granulated sugar. Mix until well blended.

Add the egg, vanilla extract, baking soda, and salt to the mixture. Stir until fully incorporated.

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Scoop out portions of the dough and roll them into balls. Place them on the baking sheet, spaced about 2 inches apart.

Flatten each ball slightly with the back of a fork to create a crisscross pattern.

Bake for 10-12 minutes until the edges are lightly golden and the centers remain soft.

Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
