Preheat the oven to 350°F (175°C).

Line a baking sheet with parchment paper.

In a mixing bowl, combine the creamy peanut butter, granulated sugar, egg, and vanilla extract.

Stir in the baking soda and salt until fully incorporated.

Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheet.

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

Gently press a chocolate kiss into the center of each cookie as soon as they are removed from the oven.

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