Preheat your oven to 350°F (175°C) to ensure even baking.

In a large mixing bowl, combine the peanut butter, sugar, egg, baking soda, vanilla extract, and salt. Mix until smooth and creamy.

Using a tablespoon, scoop out the dough and roll it into balls, placing them onto a lined baking sheet with enough space for spreading.

Flatten each ball with a fork to create a crisscross pattern.

Bake in the preheated oven for about 10-12 minutes until the edges are golden.

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