Prepare the Cookie Dough

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
2. Mix Peanut Butter and Sugars: In a large bowl, combine the peanut butter, granulated sugar, brown sugar, eggs, and vanilla extract. Mix until well combined and smooth.
3. Combine Dry Ingredients: In another bowl, whisk together the flour, baking soda, and salt.
4. Combine Mixtures: Gradually add the dry ingredients to the peanut butter mixture, mixing until just combined.

Shape the Cookies

1. Roll Dough Balls: Using a tablespoon or cookie scoop, roll the dough into 1-inch balls.
2. Roll in Sugar: Roll each dough ball in the additional granulated sugar until coated.

Bake the Cookies

1. Place on Baking Sheets: Arrange the cookie dough balls on the prepared baking sheets, spacing them about 2 inches apart.
2. Bake: Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden but the centers are still soft.
3. Add Chocolate Kisses: Remove the cookies from the oven and immediately press a chocolate kiss into the center of each cookie.
4. Cool: Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
