Preheat your oven to 350°F (175°C).

In a mixing bowl, whisk together the flour, baking soda, and salt.

In another bowl, combine the peanut butter, granulated sugar, brown sugar, egg, and vanilla extract. Mix until smooth.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Using a tablespoon, scoop the dough and roll into balls. Place them on a baking sheet lined with parchment paper.

Bake in the preheated oven for 8-10 minutes, until the edges are lightly golden.

Remove the cookies from the oven and immediately press a chocolate kiss into the center of each cookie.

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