Preheat your oven to 375°F (190°C) and line baking sheets with parchment paper or silicone mats.

In a large bowl, cream together softened unsalted butter, granulated sugar, and light brown sugar until light and fluffy, about 2-3 minutes.

Add creamy peanut butter, egg, and vanilla extract, mixing until smooth.

In a separate bowl, whisk together all-purpose flour, baking soda, and salt; gradually add to the wet mixture, stirring until just combined.

Shape 1-inch portions of dough into balls and roll in granulated sugar before placing on prepared sheets.

Bake for 10-12 minutes until lightly golden at the edges; press a Hershey’s Kiss into the center while still warm.

Cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
